The bi-amplified GENELEC 1032B is a two
way active monitoring speaker designed for
high output, low coloration and broad band-
width. It is based on the famous 1031A near
field monitor but offers extended low fre-
quency output with an increased maximum
SPL.
Due to its compact size, integrated con-
struction, 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 cir-
cuitry. The DCW™ Technology used provides
excellent frequency balance even in difficult
acoustic environments.
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
achieved with the revolutionary DCW Tech-
nology pioneered by Genelec. The DCW also
provides perfect phase and delay uniformity
at the crossover frequency.
Both drivers are magnetically shielded.
Crossover
The active crossover network consists of two
parallel bandpass filters. Acoustically the fil-
ters are complementary and the slopes are
24 dB/octave. The crossover frequency is set
to 1,8 kHz. Using the active crossover con-
trols ('treble tilt', 'bass tilt' and 'bass roll-off')
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 vibra-
tion isolators, to ensure rattle free operation
and long term reliability. The bass and treble
amplifier produce respectively 180 W and 120
W of short term power. The fast, low distor-
tion 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 protec-
tion and amplifier thermal overload protection.
Variable input sensitivity allows for accurate
level matching to the console output section.
Installation
Each 1032B monitor is supplied with a mains
cable and an operating manual. After unpack-
ing, place the speaker so that its acoustical
axis (see figure 2) is aimed towards the lis-
tening position. Do not place the speaker in a
horizontal position as this may cause acousti-
cal cancellation problems around the crosso-
ver frequency.
Sufficient cooling for the amplifier must
be ensured if the speaker is installed in a
restricted space such as a cabinet or inte-
grated 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 suf-
ficiently large to dissipate heat so that the
ambient temperature does not rise above 35
degrees Celsius (95°F).
Before connecting up, ensure that the
mains switch is off (see figure 1). Check that
the mains voltage selector is correctly set
(Models sold in Europe have a fixed 230 V
setting). Audio input is via a 10 kOhm bal-
Audio input is via a 10 kOhm bal-
anced 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.
Autostart function
The signal sensing Autostart function of the
loudspeaker powers it up when playback
begins. Automatic powering down of the
loudspeaker happens one hour after the
playback has ended and the loudspeaker
goes to standby mode. The power consump-
tion in standby mode is less than 0.5 watts.
The loudspeaker will automatically and rap-
idly start once an input signal is detected
from the source.
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 sensi-
tivity control on the rear panel (see figure 1).
A small screwdriver is needed for the adjust-
ment. 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.
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 ane-
choic 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.
Console top mounting
If the 1032B’s are used for for near field moni-
toring, 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.
Maintenance
No user serviceable parts are to be found
within the amplifier unit. Any maintenance
or repair of the 1032B unit should only be
undertaken by qualified service personnel.
Safety considerations
Although the 1032B has been designed in
accordance with international safety stand-
ards, to ensure safe operation and to main-
tain the instrument under safe operating con-
