SYSTEM The Genelec 1032A is a two-way
active monitoring system including magnetically shielded loudspeaker drivers, speaker enclosure, mul­tiple power amplifiers and active, low signal level crossover. Based on the famous 1031A near field monitor, the 1032A offers extended low frequency response and an increased maximum SPL. Due to it's compact size, this system is ideal for high power near field moni­toring. Furthermore, it is well suited to general purpose broadcasting applications, TV control rooms, mobile vans and CD mastering as well as home studios.
The unique Directivity Control Waveguide (DCW) Technology used provides excellent stereo im­aging and frequency balance even in difficult acoustic environments. The fast, low distortion amplifiers are capable of driving the stereo system to peak output levels in
excess of 124 dB SPL at 1 m with program signals. Versatile crossover controls allow for precise matching of the speaker system to different acoustic condi­tions. The system can be used in both vertical and horizontal orienta­tion by simply rotating the DCW unit.
INTEGRATED CONSTRUCTION The system is very easy to use as
only mains power and input signal are needed. Uniform performance is obtained through the integration of the loudspeakers and amplifiers as a complete matched and cali­brated package. The rugged am­plifier is mounted into the enclosure with vibration isolators which also act as quick release hinges making maintenance operations very easy and straightforward. The speaker cabinet is constructed of veneered MDF, which is heavily braced to eliminate structural resonances.

AMPLIFIERS The bass and treble amplifiers each
produce 180 W and 120 W respec­tively of short term power with very low THD and IM distortion. Special attention has been paid to the elec­tronic design to ensure the highest subjective sound quality currently possible. The system incorporates special circuitry for driver overload protection. Thermal protection is included for the amplifiers.

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 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 repro-
duced 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.
DCW TECHNOLOGY The revolutionary Directivity Con-
trol 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
Calibrated 'Tilt' switch. MUTE disconnects the channel for testing.
+2 to +6 dB thus increasing the system maximum sound pressure level.
The tweeter driver is mounted in a DCW to match the dispersion characteristics to that of the bass driver. The DCW may be rotated for horizontal or vertical mounting.
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.
