SYSTEMSYSTEM

SYSTEM

The Genelec 1029A is a very com-

pact bi-amplified active monitor

system, which has performance

comparable to much larger sys-

tems. The vented speaker

enclosure contains an amplifica-

tion unit. This unit includes an

active electronic crossover, over-

load protection circuitry and two

power amplifiers, one for each

driver. The system's excellent dis-

persion and precise imaging,

together with its compact size,

make it ideal for near field monitor-

ing, mobile vans, home studios,

multimedia and home theatres.

The Genelec 1029A has been spe-

cially 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 re-

quired, it can be complemented

with the 1091A subwoofer, which

has a lower cutoff point of 38Hz.

Genelec’s unique Directivity Con-

trol Waveguide (DCW) technol-

ogy is used to provide excellent

stereo imaging and frequency

balance, even in difficult acoustic

environments. Versatile tone con-

trols 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 orienta-

tion.

CONSTRUCTIONCONSTRUCTION

CONSTRUCTION

The 1029A is very easy to set up

and use, the only connections re-

quired 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, elimi-

nating the effects of component

tolerances and ensuring consist-

ent quality. The rugged cast

aluminium cabinet has rounded

corners and a hard-wearing

painted outer surface.

CROSSOVER FILTERSCROSSOVER FILTERS

CROSSOVER FILTERS

The amplifier unit contains an ac-

tive crossover, a feature more

commonly used in large and ex-

pensive control room monitors.

This is the ideal method for divid-

ing the input signal between the

driver units. The active crossover

allows the overall response of the

system to be optimized to an ex-

tent impossible with a passive

system. To maintain uniform fre-

quency 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 CONNECTORSINPUT CONNECTORS

INPUT CONNECTORS

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 hav-

ing 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.

AMPLIFIERSAMPLIFIERS

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 high-

est subjective sound quality

currently possible. The amplifier

unit also contains a protection cir-

cuit that monitors the output levels

and prevents any damage to the

drivers. This makes the system

immune to overloads and spuri-

ous signals.

DRIVERSDRIVERS

DRIVERS

A 19 mm (3/4") metal dome tweeter

is loaded by a DCW, and is used

to reproduce the high frequen-

cies. 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 fre-

quency is 68 Hz and the low

frequency response extends

down to 65 Hz (-6dB).

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 TECHNOLOGYDCW TECHNOLOGY

DCW TECHNOLOGY

The revolutionary Directivity Con-

trol Waveguide (DCW) technology

is a means of greatly improving

the performance of a direct radi-

ating multi-way loudspeaker

under normal listening conditions.

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 re-

sponse on and off axis. In addition,

the improved directivity control

causes more direct sound and

less reflected sound to be re-

ceived at the listening position.

This provides improved stereo

imaging and ensures that the sys-

tem is less sensitive to differing

control room acoustics than con-

ventional direct radiator design.

The DCW Technology improves

the drive unit sensitivity by +2 to

+6 dB (depending on the particu-

lar application), thus also

increasing the available system

maximum sound pressure level.

MOUNTINGMOUNTING

MOUNTING

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 Omni-

mount® size 50 bracket,for which

two M6x10mm screws are re-

quired. 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. Fric-

tion pads are provided for

placement on a shelf or a stand.

OPTIONSOPTIONS

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 loud-

speaker are black regardless of

cabinet colour. Other options in-

clude wall and ceiling mounts,

table stand and soft carrying bag.

Ask your local Genelec dealer for

more details.
