Genelec 1032A Monitoring Speaker

System

The bi-amplified GENELEC 1032A is a two way active monitoring speaker designed for high output, low coloration and broad bandwidth. It is based on the famous 1031A near field monitor but offers extended low frequency output with an increased maximum SPL. Due to its compact size, integrated construction, excellent dispersion and precise stereo imaging this speaker system is ideal for Near Field monitoring, mobile vans, broadcast and TV control rooms and home studios. Designed as an active speaker, this unit contains drivers, power amplifiers, active crossover filtering and protection circuitry. The DCW Technology used provides excellent frequency balance even in difficult acoustic environments.
achieved with the revolutionary DCW Technology pioneered by Genelec. The DCW also provides perfect phase and delay uniformity at the crossover frequency. Both drivers are magnetically shielded.

Installation

Each 1032A monitor is supplied with a mains cable and an operating manual. After unpacking, place the speaker so that its acoustical axis (see figure 2) is aimed towards the listening position. Do not place the speaker in a horizontal position as this may cause acoustical cancellation problems around the crossover frequency. Sufficient cooling for the amplifier must be ensured if the speaker is installed in a restricted space such as a cabinet or integrated into a wall structure. The minimum clearance for the amplifier is 10 centimeters (4") to any object. The space adjacent to the amplifier must either be ventilated or sufficiently large to dissipate heat so that the ambient temperature does not rise above 35 degrees Celsius (95F). Before connecting up, ensure that the mains switch is off (see figure1). Check that the mains voltage selector is correctly set (Models sold in Europe have a fixed 230 V setting). Audio input is via a 10kOhm balanced XLR connector, but unbalanced leads may be used as long as pin 3 is grounded to pin 1 of the XLR (see figure 3). Once the connection has been made, the speakers are ready to be switched on.

Crossover

The active crossover network consists of two parallel bandpass filters. Acoustically the filters are complementary and the slopes are 24 dB/octave. The crossover frequency is set to 1,8 kHz. Using the active crossover controls ('treble tilt', 'bass tilt' and 'bass rolloff') this speaker to be exactly matched to any room environment.

Amplifiers

The amplifier unit is mounted to the rear of the speaker enclosure on quick release vibration isolators, to ensure rattle free operation and long term reliability. The bass and treble amplifier produce respectively 180W and 120 W of short term power. The fast, low distortion amplifiers are capable of driving a stereo system to peak output levels in excess of 124 dB SPL at 1 m. The unit incorporates a special protection circuitry for driver overload protection and amplifier thermal overload protection. Variable input sensitivity allows for accurate level matching to the console output section.

Drivers

The low frequencies are reproduced by a 10" (250 mm) bass driver loaded in a 24 liters vented cabinet. The -3dB point lies at 40 Hz and the low frequency response extends down to 36 Hz (-6dB). The high frequency driver is a 1" (25 mm) metal dome with pure piston behavior up to 23 kHz. The uniform dispersion control is

Setting the input sensitivity
The input sensitivity of each speaker can be adjusted to match the mixing console output level or other source by using the input sensitivity control on the rear panel (see figure 1). A small screwdriver is needed for the adjustment. The manufacturer default setting for this control is -6 dBu (fully clockwise) which gives SPL of 100 dB @1m at -6 dBu input level. Note that to get the full output level of 113 dB SPL, an input level of +7 dBu is needed at this setting.

Console top mounting

If the 1032As are used for for near field monitoring, avoid mounting the speakers on the meter bridge of the console. Instead position them slightly behind the console by using floor stands or wall mounts. This prevents the the first reflections from the console surface from coloring the direct sound.

3. To prevent fire or electric shock, do not expose the unit to water or moisture. Do not place any objects filled with liquid, such as vases on the speaker or near it. 4. Note that the amplifier is not completely disconnected from the AC mains service unless the mains power cord is removed from the amplifier or the mains outlet. WARNING! This equipment is capable of producing sound pressure levels in excess of 85dB, which may cause permanent hearing damage.

Maintenance

No user serviceable parts are to be found within the amplifier unit. Any maintenance or repair of the 1032A unit should only be undertaken by qualified service personnel.

Setting tone controls

The response of the system may have to be adjusted to match the acoustic environment. The adjustment is done by setting the three tone control switch groups treble tilt, bass tilt and bass roll-off on the rear panel. The factory settings for these controls are All Off to give a flat anechoic response. See Table 1 for suggested tone control settings. Figure 5 shows the effect of the controls on the anechoic response. Always start adjustment by setting all switches to OFF position. Then set only one switch to the ON position to select the response curve needed. If more than one switch is set to ON (within one switch group) the attenuation value is not accurate.

Safety considerations

Although the 1032A has been designed in accordance with international safety standards, to ensure safe operation and to maintain the instrument under safe operating conditions, the following warnings and cautions must be observed: 1. Servicing and adjustment must only be perfor med by qualified ser vice personnel. The amplifiers rear panel must not be opened. 2. Do not use this product with an unearthed mains cable as this may lead to personal injury.

CROSSOVER FILTERS The crossover frequency of the active crossover is 1.8 kHz. In order to obtain uniform frequency balance in differing acoustic conditions, special calibrated controls are included in the crossover. Three such controls are at the users disposition including treble and bass tilt, and bass roll-off switch. Each of these controls allow for adjustment in 2 dB increments and also provide the possibility of muting the channel for test purposes. A high pass filter is included in the LF channel to protect the woofer from subsonic signals. The crossover network is driven by an active balanced input stage. Variable input sensitivity allows for accurate level matching to the mixing console.
The reference axis lies between bass and tweeter drivers.
The upper curve group shows the horizontal directivity characteristics of the 1032A in its vertical configuration measured at 1 m. The lower curve is a 1/3 octave band power response, measured in an IEC approved reverberation chamber.
DRIVERS The bass frequencies are reproduced by a 250 mm (10") bass driver loaded by a 24 litre vented box. The -3 dB point is 40 Hz and the low frequency response extends down to 36 Hz. The high frequency driver is a 25 mm (1") metal dome, with pistonic behavior upto 23 kHz, is loaded by a proprietary DCW. Both drivers are magnetically shielded for applications where the stray magnetic field must be minimized.
Calibrated 'Tilt' switch. MUTE disconnects the channel for testing.

The upper curves show the effect of the 'bass tilt' control on the free field response. The lower curves show the effect of the 'treble tilt' and 'bass roll-off' controls.
DCW TECHNOLOGY The revolutionary Directivity Control Waveguide Technology is a means of greatly improving the performance of a direct radiating multiway loudspeaker under normal listening conditions. The basic idea is to match the different drive units precisely, in terms of both frequency response and directivity. This will result in a smoother and virtually uncoloured off-axis system response. Also, due to improved directivity control, especially in the midrange frequencies, more direct sound and less early boundary reflections are received at the listening position. This gives improved stereo imaging and ensures the system is less sensitive to differing control room acoustics than any conventional direct radiator design. The DCW Technology improves the drive unit sensitivity by
+2 to +6 dB thus increasing the system maximum sound pressure level.
