Pioneering at Air Studios
Hampstead 23/07/09 Well, there was no excuse for me not to walk the eight minutes down the road from Hampstead Village to visit Air and spend much of a day drinking in that heady musical atmosphere. We got to talk to recording engineers, sample sounds in monitoring suites and hear demos in the studio areas themselves. While we have heard it before the key message, was we are out of plasma, lovely though it was. The Pioneer flat TV business was rumoured to be profitable only in the UK and this highly regarded vision line will finally be closed out this year though some valuable, licensable technology patents remain from the endeavour. The new message is We are returning to our traditional core business, which is AUDIO By way of proof we were educated in Pioneers long history in quality audio, in fact long pre-dating Hi Fi as we have come to know it. While Rice and Kellog got the mass controlled, essentially flat response cone speaker right by 1926, it was very soon after that the founder of Pioneer, the company and the brand had designed a refined drive unit using this advanced technology. They have long taken loudspeakers seriously and these were the foundation of the business for decades, and are planned to become influential again. Here presenting new speaker lines was Bertrand Mellot (- Pioneer France) with input from Japan , the US TAD division and the European industrial design and product group based in Paris, these models are intended to embody technologies , performances and standards derived from their professional speaker products. Recording engineer Tim Vine-Lott of Air Studios was on hand and his responsibility includes helping to voice the Pioneer audio products with reference to the Air studio house sound and available recordings. Event MC Mike OMahoney , UK General Manager of Pioneer explained that they were regrouping to concentrate on their audio core though activity in multichannel audio and home cinema was to remain important with two new Blu ray players and two receivers launched at this event, joining existing models including the flagship. That was showcased with its new iPod and iPhone connectivity, including video material, this achieved with simple cables namely USB and RCA jack video, and without need for a custom dock. The revised operating systems can be downloaded to an existing receiver via its own dedicated internet port, or downloaded to a cd and played back into the unit.
A-8 (Our first ever speaker)
While BitStream multi-channel HD audio is just fine as it is on the so equipped the Bluray releases, those with PCM audio tracks suffer transmission loss when sent, as is usual, down the HDMI link and so like other players in this arena Pioneer have a crystal clock reference arrangement which substantially removes audio jitter occurring in the HDMI path, and they did successfully demonstrate the improvement as better sound. The new receivers use a customised Icepower Class D amplification which efficiency allows Pioneer to claim full continuous rated power from all 7 channels simultaneously, good on the test bench but I wonder whether this ever happens in real life. Certainly the efficiency does allow for physically smaller powers supplies, less transformer iron , much smaller heats sinks and less weight to transport around the planet. A total of 720W was claimed which should make a loud enough noise. It was a treat to hear a full home theatre system using the classy, established Pioneer EX speaker series, these clearly of international audiophile standard and showing off their TAD pedigree, though the open plan small studio space used was not very representative of home use unless you have a 240 cubic metre listening room. In straight stereo mode the centre image was so pin point sharp I could have sworn that the centre channel speaker present was operative. An impressive HT surround demo followed, unquestionably well set up. A few attendees stayed behind for an exclusive demo of some other full spec TAD monitoring speakers after the main show, of which more later.

The second course was the premier of some Pioneer stereo separates, two integrated amps, two CD/SACD players and the first models of a new euro speaker line. Quoting Pioneer : Tthe new G-Clef Audio Series: Available from July, the new G-Clef products, all with elegant cosmetic designs and leading technologies for immersive musical experiences, include the A-A9MK2-K and A-A6MK2-K amplifiers, the PD-D9MK2-K and PDD6MK2-K Super Audio CD players and the F-F6MK2-K tuner.
The A-A9MK2-K Stereo Amplifier: There is also a line of smaller EX speakers designed in France, including the full home theatre set.

INTRODUCTION

TAD History

Founded in 1975, Technical Audio Devices (TAD) has continued to stand at the frontier of cutting-edge sound technology, maintaining a well-established tradition of creating high performance speakers for professional use. TAD products are designed, crafted, and produced with strict adherence to the most rigorous standards demanded by musicians and professional audio-system designers around the world. TAD loudspeaker components are found in studio monitors, sound reinforcement systems, public address and concert hall speakers, cinema theater audio systems, and many other applications that require the highest-quality sound reproduction. With this high standard of quality, world-class recording studios rely on TAD components for original recordings and digital remastering of audio performances. In recent years, TAD has met the demand for high-quality home audio speakers by delivering world class audio components that carry the TAD pedigree into the home.
TAD Reference One Description
The TAD Reference One loudspeaker is a breakthrough product for the home audio market, and represents the culmination of over 30 years experience in developing class-leading loudspeakers for the professional studio monitoring environment. Central to the performance of the TAD Reference One loudspeaker is the Coherent Source Transducer (CST), a concentric unit featuring TADs unique beryllium-diaphragm design. Beryllium is used for both the tweeter dome and the midrange cone, to provide a point source radiator covering the frequency range from 250 Hz to 100 kHz. The CST is supplemented by dual 25 cm (10 in.) bass drivers enclosed in structurally inert cabinet. The result is a very wide-band, resonance-free monitor loudspeaker of the highest quality.
About The Manual And Warranty
To obtain optimum performance from this product, please carefully read the remaining pages of this owners manual, along with manuals of other components in your system. To register for warranty support, please fill out and mail the enclosed warranty card.

TECHNOLOGY

Beryllium Diaphragms

Each TAD Reference One loudspeaker features proprietary beryllium-manufacturing technology for the midrange and tweeter diaphragms. The lightest and most rigid metal available for diaphragms, beryllium performs with strength and damping characteristics unmatched by any of the materials currently used in high-end audio loudspeaker manufacturing, as shown in Figure 1. Berylliums combination of light weight and exceptional strength enables diaphragm resonance to be pushed far beyond the operating band of its drive units. This produces near-perfect piston behavior in the speakers, resulting in cleaner sound and greater accuracy of reproduction.
The heart of the system is the Coherent Source Transducer (CST), shown in Figure 2. The tweeter diaphragm is mounted concentrically within the apex of the midrange cone and provides a point source of sound from 250 Hz to 100 kHz. It is time coherent, due to the shallow midrange-cone profile made possible by the superior strength of beryllium, and produces a superbly-controlled radiation pattern. CST ensures a perfect spectral balance between the direct and reflected sounds that arrive at the listeners ears, providing a more consistent sound throughout the listening room and improved imaging capability.

Bass Drivers
The foundation of the TAD Reference One loudspeaker is the bass drivers, as shown in Figure 3. The driver cones are constructed from a tri-laminate of front and rear-woven aramid fibers that sandwich a foamed acrylic core. This provides enormous strength to the cone in order to resist any flexing due to the high forces exerted during loud bass passages. To achieve high drive linearity, the motor structure employs short coil and long gap geometry, Faraday shorting rings, and a novel flux path for even lower distortion. Combined with advanced spider and multi-roll surround design, the bass driver has over 30 mm (1.25 in.) of linear drive capability, as shown in Figure 4.

TAD-R1_En.book 7

CST Mounting Construction
The CST driver is mounted into an extremely firm enclosure that features a headboard specially formed to optimize the sound emitted from the driver. To further enhance the performance, ISO-Drive technology is used to mechanically isolate the CST driver from its mounting. This greatly reduces the mechanical energy that is the source for enclosure vibration, resulting in reduced delayed resonances and improved resolution of fine detail.

Crossover Networks

The crossover networks use only the finest components. Air cored coils, noninductive resistors, and film capacitors in the signal path are all carefully chosen and optimized for the CST driver to provide the greatest transparency to the signal. The bass drivers use laminated steel-core inductors for highpower handling and low saturation. All components are built on high-grade, glass-epoxy, printed circuit boards with thick copper traces to ensure stability and repeatability of performance.

Bass Enclosure Construction Enclosure Finish
The enclosure of the TAD Reference One's bass drivers features a frame of 21 mm (0.9 in.) thick laminated birch plywood supported by a CNC processed plywood back board spine up to 137 mm (5.7 in.) thick, clad with 50 mm (2 in.) curved side panels created by high-frequency heating. The bass reflex port was modeled after the design concept of the TAD compression driver and horn, resulting in the reduction of wind noise for clear, deep bass. In order to fully realize the drive unit's potential, the drivers are securely mounted to the enclosure and the enclosure is slanted at a four-degree tilt back, optimizing the unit's center of balance. The 150 kg (330 lb) mass of this system produces a correspondingly powerful bass sound that is both clean and subtle. The teardropshape both reduces sound diffraction, allowing for excellent acoustics, and also serves to eliminate unnecessary resonance and internal standing waves. The enclosure features rare, elegant natural wood that is treated with a transparent finish. Its surface has a beautifully polished mirrored finish, the result of the meticulous, painstaking work of skilled craftsmen. This product is designed to elicit the full potential of the natural wood used in its enclosure. Note that the color and pattern of the wood is slightly different for each unit.

INSTALLATION AND PLACEMENT
Caution: About installation
This unit is sold with the understanding that it is to be installed by a properly trained and equipped specialist. All matters concerning installation and mounting should be handled by specialists or by your local dealer. Pioneer waives all responsibility for damages to this unit as the result of improper installation/mounting, improper use, remodeling/alteration, and natural disasters.
Caution: About the placement of this unit
This product weighs 150 kg (330 lb). Make sure that you place this product upon a surface that can easily sustain this weight. Additionally, note that when using spikes, each spike supports some 50 kg (110 lb), and as such may cause damage to flooring underneath a carpet or other surfaces. To avoid causing such damage, be sure to place a sufficiently large and strong cushion underneath each spike. As a precautionary measure, be sure to not place the unit anywhere where it might fall on a sleeping individual in the event of an earthquake.

Concerning The Placement Of This Unit
There is an aluminum plate attached to the bottom of the unit's cabinet. It can be placed normally upon a flat surface. This unit comes with two types of spikes that you can use to adjust the unit to the shape of the floor for best possible placement. We recommend the following placement methods: For flat surfaces: no spikes Thick carpet or mat: cone-shaped spikes Thin carpet or mat: round spikes

Cone-shaped spike

Round spike

TAD-R1_En.book 9

Installing The Spikes
WARNING! Be sure to use two people when installing the spikes. Be careful to not pinch your fingers under the loudspeaker and make sure the loudspeaker does not fall on its side. The installation of spikes on the bottom of the unit allows you to establish a firm connection between the ground and the loudspeaker when placing the loudspeaker on uneven surfaces. The bottom of the cabinet features three areas for these spikes. The use of three spikes for support eliminates the need for fine adjustments, allowing you to keep the loudspeaker firmly in place. See Choosing Where To Place The Loudspeakers on page 10 for help deciding where to place the loudspeaker, and Figure 5 for how to install the spikes. There are screw holes on the aluminum plates located on the bottom of the cabinets.
Removing The Grille Covers
The bass drivers come equipped with grille covers that should be removed when the loudspeaker are in use (see Figure 6). To remove them, grasp each grille along the edges, pull it out, and store it in a safe place in case of future use when moving or storing this unit.

TAD-R1_En.book 10

Choosing Where To Place The Loudspeakers
Loudspeaker placement within the listening room will have a great impact upon the total performance of TAD Reference One loudspeakers in terms of bass performance, tonal accuracy, and imaging. All rooms are different and so this section is intended as a guide only. Experimentation in your room will yield optimum results. Begin by placing the rear of the loudspeakers approximately one to two feet in from the front walls and the sides one to two feet in from the side walls of your listening room, as shown in Figure 7. Your listening position should be roughly equal to the distance between the two loudspeakers. Also, turn the loudspeakers inward so each axis points toward the listening position. Next, connect the audio system as described in CONNECTING THE LOUDSPEAKERS on the next page. Then, optimize the loudspeaker placement as described in OPTIMIZING THE SYSTEM on page 16. WARNING! Keeping the spikes inserted can cause damage to the bottom of the unit in the event that you move the loudspeaker. Be sure to remove the spikes before moving the loudspeaker to another location. In order to protect the bottom of the unit from damage when moving the loudspeaker, you should place a thick cloth or mat beneath the system before moving it to a new location.

CONNECTING THE LOUDSPEAKERS

Single-Wire Connections

For single-wire connections, connect the high- and low-frequency sections of the crossover network with the shorting link that was included with this unit, then connect the (+) wire from your amplifier to either red binding post and the (-) wire from your amplifier to either black binding post, as shown in Figure 8.

Bi-Wire Connections
In a bi-wiring connection, you independently plug in the loudspeakers running from the amp to their respective high- and low-frequency plugs. This results in the CST driver and bass drivers being independently connected directly to the amplifier, offering you the freedom to optimize the cable type for each of the drivers. Connect one set of wires to the bottom set of binding posts (bass driver-specific network). Then connect a second set of wires to the top binding posts (CST-specific network). Next, connect both sets of wires to the appropriate terminals on your amplifier. Take care to connect both (+) wires to the (+) amplifier terminals and both () wires to the () amplifier terminals, as shown in Figure 9.

Bi-Amplification Connections
Bi-Amplification allows the best performance from the TAD Reference One loudspeaker by using dedicated amplifiers for low- and high-frequency sections. There are two possible configurations, commonly referred to as horizontal and vertical bi-amping. WARNING: Remove the shorting links before connecting speaker cables in bi-wiring connections. Failure to do so may result in damage to your amplifiers.
Vertical Bi-Amping With this configuration, identical stereo amplifiers are used for each loudspeaker. One channel of each amplifier drives the low frequency section and the other channel drives the high frequency section, as shown in Figure 10. Connect one set of wires and amplifier channel to the bottom set of binding posts (bass driver-specific network). Then connect a second set of wires and the other amplifier channel to the top binding posts (CST-specific network). Take care to connect both (+) wires to the (+) amplifier terminals and both () wires to the () amplifier terminals.

Horizontal Bi-Amping With this configuration, you may use different stereo amplifiers for the low- and high-frequency sections of the loudspeaker (e.g., tube amplifiers for high frequency and solid state for low frequency). Each channel of one amplifier drives the low-frequency section of each loudspeaker and each channel of the other amplifier drives the high-frequency section, as shown in Figure 11.
This method requires that both amplifiers have the same gain; otherwise an imbalance will be heard between the low- and high-frequency reproduction from the loudspeaker. If in doubt, please consult your TAD dealer.

OPTIMIZING THE SYSTEM
Improving Bass Performance
Select a music track with well-recorded bass, such as acoustic string bass. Listen for all the bass notes having roughly equal level. If any notes jump out at you more strongly than others, try moving the TAD Reference One loudspeakers until you get the most even progression of the notes. Typically, moving them towards the walls will increase low bass output, but can result in more unevenness higher up the musical scale. Moving them closer to the side walls will not produce the same effect as moving closer to the back wall, so try experimenting moving both ways for the most pleasing sound. Also listen to drum sounds. The kick drum should sound tight and fast, without low-frequency boom. Changes in loudspeaker position of as little as a few inches can have a large effect upon bass performance, so take time and try many positions. A useful tip to speed up the process is to have a partner move around the room while talking. Listen to where the voice sounds most natural, without added chestiness, and position the loudspeaker in that location. performance of the CST driver, the strength of the side-wall reflections will be reduced, and at the same time, the image will be stabilized and focused. Now listen to music with well-recorded acoustics. Check that the image is wide and deep. Limited depth suggests that the speakers are placed too close to the front wall. Try moving them forward.

Final Optimization

You may find that as you move the loudspeakers to optimize one aspect of performance another worsens; for example, trading improved image accuracy for poorer bass response. If this occurs, try moving your listening position. Bass response is governed strongly by both loudspeaker and listening positions, whereas imaging is mostly determined by the loudspeaker position. Therefore, you may find that if optimizing for imaging compromises bass, then changing the listening position will bring back bass performance. The room characteristics will also have a profound influence upon the sound. Live rooms, with few soft furnishings and hard floors, will impart an artificial sense of spaciousness to the sound but reduce the intimacy and accuracy. Overly dead rooms, with lots of furnishing, carpets, and drapes will produce a very dry, lifeless sound and require lots more power to drive the loudspeakers to adequate sound levels. The optimum is somewhere in-between. Avoid hard, unbroken, parallel walls, especially side walls, as these impart strong flutter-type echoes and will have a bad influence on the imaging. Try and break up long expanses of walls with drapes, wall hangings, or bookshelves, and try not to introduce too much asymmetry into the room layout, as this will also affect the imaging.

Improving Imaging

Now select music with a strong center image. Listen for that image to be exactly centered between the loudspeakers, and to be well-focused. If the image is unclear and spreads wide, the side walls are probably creating strong reflections. Try moving the loudspeakers closer together to reduce this effect. If this brings them too close, try instead toeing in the loudspeakers so that the axis crosses in front of the listening position. Because of the superior off-axis

TAD-R1_En.book 17

LOUDSPEAKER CARE
Each TAD Reference One loudspeaker has a polymer finish that requires care similar to a grand piano. For accumulated dust and fingerprints, simply wipe the cabinet with the included cleaning cloth. CAUTION: Do not use any cleaners or polishes on the cabinet or grille! In areas of high humidity, use a dehumidifier, and in areas of excessive dryness, use a humidifier to adjust the rooms humidity level. Avoid exposure to direct sunlight, and do not install in areas near by heating appliances. Conditions considered unpleasant by humans are detrimental to speakers as well. Providing a comfortable environment for the speakers will assist them in demonstrating their best performance. Please maintain the usage environment as follows: Temperature: 15 C to 25 C Relative Humidity: 35 % to 65 % (winter) 40 % to 70 % (summer) When using room air-conditioners or stoves to rapidly cool or heat room spaces, take precautions to avoid excessive dehumidification. Do not try to force a low-powered amplifier to produce loud volumes of sound (the amplifiers harmonic distortion will be increased, and you may damage the speaker).
