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 contains an amplification 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 theatres.
The Genelec 1029A has been specially designed to have a sufficient
LF extension (-3dB at 68Hz) for
most monitoring applications.
However if greater SPL's and a
lower cutoff frequency are required, it can be complemented
with the 1091A subwoofer, which
has a lower cutoff point of 38Hz.
Genelec’s unique Directivity Con-

trol Waveguide (DCW) technology is used to provide excellent
stereo imaging and frequency
balance, 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 1m. The speakers may be used
in a vertical or horizontal orientation.

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
amplifiers 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

INPUT CONNECTORS

The amplifier unit contains an active crossover, 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 maintain 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.

The input is made via a balanced
XLR female 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 monitor 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.

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 (-6dB).

Figure 3: Using two sources.

Protective grills are positioned in
front of both drivers. Magnetic
shielding is standard on the 1029A.
Shielding is vital for applications
such as video post production,
where stray magnetic fields must
be minimized.
DCW TECHNOLOGY
The revolutionary Directivity Control Waveguide (DCW) technology
is a means of greatly improving
the performance of a direct radiating multi-way loudspeaker
under normal listening conditions.

Figure 4: Using one monitor and a
stereo source.

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 amplifier
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.

One of the basic aims is to match
the performance of the drivers in
terms of both frequency response
and directivity. This results in a
smoother overall frequency response on and off axis. In addition,
the improved directivity 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 (depending on the particular application), thus also
increasing the available system
maximum sound pressure level.

OPTIONS
The 1029A is available in three
colours: black, grey and white.
The driver's protective grilles,
volume and power knobs and
stickers on the back of the loudspeaker are black regardless of
cabinet colour. Other options include wall and ceiling mounts,
table stand and soft carrying bag.
Ask your local Genelec dealer for
more details.

There are several possibilities for
mounting the 1029A. On the base
of the monitor is a 3/8" UNC threaded
hole which can accommodate 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.
