Use the POWER switch located on the front panel to power-on the appliance. The soft-start function protects against current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on. The loudspeaker outputs are activated via relay switching with a delay of approximately 3 seconds to efficiently attenuate eventual power-on noise. The PROTECT LED lights during the delay time and the fans run at maximum speed. This is normal, confirming the protection circuitrys immaculate operation.
This indicator lights when the power amplifier has been switched on. Causes for the POWER-indicator not lighting are: the appliance is not connected to the mains network or a defective primary fuse The PROTECT LED lights indicating that one of the internal protection circuits against thermal overload, short-circuit, Back-EMF, HF-occurrence at the output, etc., has been activated. The output relays interrupt the connected load from the power amps while input signals are interrupted as well, preventing the connected loudspeaker systems and the power amplifier itself from being damaged. Whatever caused the fault e.g. a short-circuited speaker cable needs to be remedied. In case of thermal overload you have to wait until the power amplifier automatically regains normal operation. The SIGNAL LED lights as soon as an audio signal of approximately 30dB below full modulation is present at the output. The LED is dimmed when speaker cables are short-circuited or a protection circuit has been activated The 0dB LED lights whenever the power amplifier is driven at its limits. Higher input voltage does not result in higher peak output voltage. In addition, the 0dB indicator comes in handy when adjusting external limiters. This indicator lights as soon as one of the integrated dynamic audio signal limiters is being activated and the power amplifier is driven at the clipping limit or generally at its maximum capacity. Short-term blinking is not a problem, because the internal limiter trims input levels of up to +21dBu down to a S/N-ratio of approximately 1%. If, on the other hand, this LED lights constantly, reducing the volume is recommended to prevent the loudspeaker systems connected from being damaged by probable overload.
Detent potentiometers scaled in dB for adjusting amplification levels of SUB and TOP channels. To prevent distortion in mixing consoles connected to the amp, setting these controls to a value between 0dB and +6dB is generally recommended. The dB-scale provides direct indication of the control attenuation applied to the fixed internal amplification.
The electronically balanced INPUT offers an input sensitivity of 0dBu (775mV) for direct connection of mixing consoles, equalizers, etc. The XLR-type connector OUTPUT is prepared for throughconnecting input signals to additional external power amps. The input signal is directly routed to the output connector. There are no repeaters or other electronic components within that signal path. Accordingly, input and output connectors are directly interconnected in parallel, offering permanent electrical connection, without regard to the setting of the Power-ON switch.
Choosing high-quality balanced cables (two conductors for the audio signal plus separate shielding mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting unbalanced cables to the power amplifier inputs is possible as well, using balanced cables is always preferable. A great number of todays audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction of external interference mostly noise and hum.

POWER AMPLIFIER OUTPUT CONNECTORS
Power amp output connection for SYSTEM, SUB and TOP channels is provided via professional SPEAKONtype output connectors. This mechanically and electrically safe connection method complies with any safety standard allowing the use of high-performance loudspeaker cables with diameters of up to 4 x 2.5mm2. The DYNACORD accessory program offers single connectors and couplings as well as high-performance loudspeaker cables. The four poles of the system connector are assigned as follows: the low-frequency signal is present via pins 1+ and 1- while pins 2+ and 2- carry the Mid/ Hi-range audio signal. Using four-pole SPEAKON speaker cables allows quick, trouble-free and correct connection of loudspeaker cabinets that provide system connectors like FX 12 and FX 20. A plastic lid covers SUB and TOP connectors to prevent inadvertent erroneous connection. Remove these covers only in the event that you are going to connect speaker systems that do not provide system connectors. Keep in mind that the bass and mid/hi audio signals are present on the SUB and TOP connectors pins 1+ and 1-.
Caution: The FLASH symbol at the loudspeaker connectors indicates that high voltages are present at these connectors which, when getting in contact, can cause harm to someones health.
The ground-lift switch allows eliminating noise loops. When operating the power amplifier in a 19 rack-shelf system or cabinet together with other equipment, setting the switch to its GROUNDED position is recommended. When operating the power amplifier together with appliances with differing ground potentials, set the switch to its UNGROUNDED position.
Under normal circumstances, the mains fuse only blows in case of fault. Replacing the fuse is only permissible for authorized service personnel using a new fuse of the same type with identical amperage, voltage and blow characteristics. The high-performance mains cord supplied with your power amplifier complies with applicable safety regulations, plus that its diameter corresponds to the power amps power output capacity. Whenever possible make sure to use the supplied mains cord for connecting the power amp to the mains network. Using a different mains cord with a smaller diameter results in higher leakage, consequently reducing the amplifiers maximum power output capacity.
MAINS OPERATION & RESULTING TEMPERATURES
MAINS OPERATION & RESULTING POWER AMP TEMPERATURES
The following tables are useful in determining power supply and cabling requirements. The power drawn from the mains network is converted into acoustic output to feed the connected loudspeaker systems plus heat. The difference between drawn power and dispensed power is referred to as leakage power or dissipation (Pd). The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table is meant as auxiliary means for calculating temperatures inside of rack-shelf systems/cabinets and the ventilation efforts necessary. The column Pd lists the leakage power in relation to different operational states. The column BTU/ hr shows the dispensed heat amount per hour. Pd (5) [W] BTU/hr(1)

NOTES ON ADJUSTMENTS
1. 2. 3. 4. 5. Turn the EQ controls on the mixing desk to a central position (linear setting). Switch any third-octave or octave equalisers to Bypass or set the equaliser controls to a central position. Connect a microphone and use the SUB and TOP control of the power amplifier to set the signal in such a way that the human voice sounds natural. This concludes the basic system setup. Using the EQ controls, a wide variety of microphone and instrument inputs can now be adjusted on the mixing desk to match personal preference.
EQUALISER Third-octave or octave equalisers should be set very carefully, if at all. With many third-octave or octave equalisers, even slight alterations in Lo or Mid range lead to unacceptable sound falsifications which cannot be eliminated via other EQ controls. ADJUSTMENTS WITH REAL TIME ANALYSER AND EQUALIZER Fine tuning of amplifier and loudspeaker systems with real time analysers and third-octave or octave equalisers is not normally advisable. Depending on the setting in question, third-octave equalisers in particular cause phase and group time distortions which falsify the sound considerably. The measuring microphone evaluates both the cabinet direct sound field and the reflections simultaneously, thus preventing any proper interpretation of the readings from a sound point of view. If particularly unfavourable acoustic conditions make fine tuning seem necessary, the following principles should be adhered to when tuning amplifier and speaker systems: 1. Only measure in the direct speaker sound field, normally at a distance of 3 - 5 metres maximum. If the measuring microphone is set up further away, (e.g. in the middle of the hall), both direct and room sound is measured. Any attempt to linearize this blend with EQ normally produces an extremely mid-, tinny- sounding, obtrusive sound image. When measuring in the critical range between ca. 250 Hz - 5 kHz, only cut with the EQ - do not boost on any account! A gap in the spectrum is not considered so obtrusive as a hump. It is essential to avoid substantial increases in the bass range as this would drastically impair the transient response of the entire system. When measuring, only work with 5 W maximum capacity (pink noise). This prevents amplifier clipping and related distortions. With conventional noise generators the peak value of the noise voltage is approximately 10 dB higher than the RMS value, meaning that even 5 W amplified power can lead to short-term peaks of up to 50 W. Dominant acoustic feedback can sometimes be suppressed somewhat by third-octave equalisers or parametric EQs. In applications of this nature, great care should be taken to ensure that the gain in volume does not mean reduced clarity and naturalness.
GENERAL INSTALLATION NOTES
GENERAL INSTALLATION NOTES When installing a sound reinforcement system for halls or festival tents over their entire length, the loudspeaker systems have to be set up on the left and right sides of the stage, slightly pointing to the center, resulting in a beamshape coverage pattern over the length of the hall or festival tent. Placing Mid/Hi cabinets on both sides on top of each other (STACKING) provides improved long-throw coverage. Stacking the loudspeaker systems in this way almost doubles coverage while at the same time near field reproduction is not too loud. When installing a sound reinforcement system for halls or festival tents on the wider wall side, the loudspeaker systems have to be set up on the left and right sides of the stage, aimed towards the audience. Because of the wider horizontal dispersion angle needed (covering the front and the sides), this kind of sound reinforcement application can only be satisfactory realized when employing two Mid/Hi cabinets per side. Exceptionally preferable for these applications is the stack and splay technique - turning the two MID-HI cabinets, which are placed on top of each other which results in smoother sound reproduction over the entire audience area. In many halls and festival tents low-frequency response can be dramatically improved by placing the woofer systems directly on the floor instead of on the stage. In return this requires installing the Mid/Hi cabinets on loudspeaker pole-stands. Arraying woofer systems in a center cluster results in extreme lowfrequency SPL in the proximity of the woofer cluster with SPL dropping rapidly over distance. Compared to woofer-cluster-configuration, de-centralized placing the woofer systems on the floor along the edge of the stage results in reduced lowfrequency SPL in the audience area next to the stage. De-centralized placing on the floor along the edge of the stage on the other hand provides considerably improved low-frequency response over wider distances.
EXAMPLES FOR ACTIVE 2-WAY APPLICATIONS
Fig. 1 shows a standard setup consisting of 2x Xa 4000, 2x FX12 used as Mid/Hi cabinets and 4x FX 20 used as woofer cabinets. This all-purpose setup fulfills the requirements of most applications. The use of four FX 20 bass cabinets produces solid low-frequency sound reproduction, which is most favorable for revival and jazz-rock bands as well as for other bass drum-oriented musical styles when performed in medium size clubs or festival tents. Sound reinforcement of side areas can be realized through employing additional sidefill speaker systems, like for example compact 2- or 3-way fullrange cabinets, which are simply connected via the TOP-Speakon socket of the Xa 4000. This connector carries the Mid/Hi audio signal via pins 1+/1-.
Fig. 2 shows a variation of the standard setup that is advantageous for wider stages. Whenever placing the loudspeaker cabinets on stage is possible, in most cases the use of a single FX 20 woofer to elevate the FX 12 Mid/Hi cabinet in the correct height on top of the woofer is sufficient. The remaining two woofer cabinets are configured as center cluster in the middle and in front of or under the stage providing homogeneous coverage of the audience area. In addition to that extra degree of homogeneous coverage this left-centerright setup allows achieving higher SPL in the low-frequency range.
Fig. 3 shows the possibility of how to achieve even higher SPL through employing an additional FX 20 woofer and Mid/Hi cabinets on each side of the stage. Additional cabinets are simply connected in parallel to the existing speaker systems. Of course, configuring woofers in a left-center-right setup as outlines in Fig. 2 is possible without problem. Stacking the Mid/Hi cabinets on top of each other almost doubles coverage, without the drawback of too high acoustic output in the proximity of the stage. Using the stack & splay technique turning the stacked Mid/Hi cabinets so that they aim at slightly different angles even improves coverage of the audience area.
Fig. 4 shows a setup consisting of a complete Xa standard installation per side, which is especially suitable for major clubs and large festival tents up to a size of approximately 3000 sqm. If needed, this configuration allows expanding each Xa system through adding additional loudspeaker cabinets (please refer to Fig. 3). The left-center-right setup delivers noticeably more SPL in the low-frequency range and most of all provides truly homogeneous dispersion and coverage in the audience area, without the annoyance of interference. This configuration is particularly recommendable for wide stages.
