1029A Active Monitoring System
System
The Genelec 1029A is a very compact bi-
amplified active monitor system, which has
performance comparable to much larger
systems. The vented speaker enclosure con-
tains an amplifi cation unit. This unit includes
an active electronic crossover, overload
protection circuitry and two power amplifiers,
one for each driver. The system's excellent
dispersion and precise imaging, together
with its compact size, make it ideal for near
field monitoring, mobile vans, home studios,
multimedia and home theaters.
The Genelec 1029A has been specially
designed to have a sufficient LF extension
(-3 dB at 68 Hz) for most monitoring applica-
tions. However if greater SPL's and a lower
cutoff frequency are required, it can be com-
plemented with the 7050A subwoofer, which
has a lower cutoff point of 38 Hz.
Genelec’s unique Directivity Control Wave-
guide (DCW) technology is used to provide
excellent stereo imaging and frequency bal-
ance, even in difficult acoustic environments.
Versatile tone controls allow further matching
of the system to its surroundings. A pair of
1029A's can produce peak acoustic levels of
over 110 dB SPL at 1 m.
Integrated construction
The 1029A is very easy to set up and use,
the only connections required are the mains
supply and the line level input.
The integrated design allows the amplifi ers
and the drivers to be calibrated as a single
unit, eliminating the effects of component
tolerances and ensuring consistent quality.
The rugged cast aluminium cabinet has
rounded corners and a hard-wearing painted
outer surface.
Crossover filters
The amplifier unit contains an active cross-
over, a feature more commonly used in large
and expensive control room monitors. This
is the ideal method for dividing the input
signal between the driver units. The active
crossover allows the overall response of
the system to be optimized to an extent
impossible with a passive system. To main-
tain uniform frequency balance in differing
acoustic environments, special calibrated
controls are included in the active crossover
network. These controls include treble 'tilt',
bass 'tilt' and bass 'roll-off' switches.
Input connectors
The input is made via a balanced female XLR
or a balanced 1/4" jack socket connector. The
two input connectors offer great flexibility as
they can be used in parallel. This offers the
possibility of having two sources connected
to the monitor at the same time. An additional
configuration is using a single 1029A to mon-
itor a stereo output. See figures 3 and 4.
The volume control is located on the front
panel. This allows easy level matching with
other audio equipment.
Amplifiers
The bass and treble amplifiers produce
40 W of output power each, with very low
THD and IM distortion values. The amplifiers
are designed to ensure the highest subjective

sound quality currently possible. The ampli-
fier unit also contains a protection circuit that
monitors the output levels and prevents any
damage to the drivers.This makes the system
immune to overloads and spurious signals.
Drivers
A 19 mm (3/4") metal dome tweeter is loaded
by a DCW, and is used to reproduce the high
frequencies. The DCW is integrated into the
one piece cabinet front baffle.
The 130 mm (5") woofer is a bass cone
driver mounted in a 4.5 litre vented cabinet.
The -3 dB frequency is 68 Hz and the low
frequency response extends down to 65 Hz
(-6 dB).
Protective grilles are positioned in front of
both drivers. Magnetic shielding is standard
on the 1029A. Shielding is vital for applica-
tions such as video post production, where
stray magnetic fields must be minimized.
DCW Technology
The revolutionary Directivity Control Wave-
guide (DCW) technology is a means of
greatly improving the performance of a direct
radiating multi-way loudspeaker under nor-
mal listening conditions.
One of the basic aims is to match the per-
formance of the drivers in terms of both fre-
quency response and directivity.This results
in a smoother overall frequency response on
and off axis. In addition, the improved direc-
tivity control causes more direct sound and
less reflected sound to be received at the
listening position. This provides improved
stereo imaging and ensures that the system
is less sensitive to differing control room
acoustics than conventional direct radiator
design. The DCW Technology improves the
drive unit sensitivity by +2 to +6 dB (depend-
ing on the particular application), thus also
increasing the available system maximum
sound pressure level.
Mounting
There are several possibilities for mounting
the 1029A. On the base of the monitor is a
3/8" UNC threaded hole which can accom-
modate a standard microphone stand.There
is a provision for an Omnimount®size 50
bracket, for which two M6x10mm screws
are required. Alternatively the speaker can
be hung on M4 screws with suitable heads
by one of the three keyhole slots on the
backpanel. The speaker can be hung in a
horizontal or vertical position. Friction pads
are provided for placement on a shelf or a
stand.
Options
The 1029A is available in three colours:
black, grey and white.The driver's protective
grilles, volume and power knobs and stick-
ers on the back of the loudspeaker are black
except for the bass driver grille on the white
version, which is white.
Other options include wall and ceiling
mounts, table stand and soft carrying bag.
Ask your local Genelec dealer for more
details.
