Active Balancer

System

Genelec DI8A Active Balancer converts

an unbalanced line signal to a balanced

line signal, thereby reducing its suscep-

tibility to electronic interference. It is the

perfect complement for an unbalanced

signal source output and either Genelec’s

Active Home Theatre Systems or Profes-

sional Audio Monitors.

The DI8A is designed to be installed in

an equipment rack or on a shelf near the

signal source, such as a Surround Sound

processor or preamplifier. This ensures

that the unbalanced lines are as short as

possible, thereby minimising noise pickup.

The long cable runs from the equipment

rack to the loudspeakers are then made

with balanced cables and XLR connec-

tors further ensuring that noise pickup is

minimised.

Genelec DI8A Active Balancer has

eight independent signal channels. One

of the channels has duplicated outputs,

providing easy connection for twin sub-

woofers in large systems. All signal input

connectors are gold-plated RCA’s, and

professional quality XLR’s are used for

the output channels.

The DI8A also has the provision for

remote power ON / STANDBY switching,

by either a 12 V DC trigger or switch/relay

which can be connected to the remote

control inputs on the back panel of the

DI8A. This provides easy integration to

remote-controlled equipment combina-

tions. The DI8A is equipped with a muting

circuit to reduce noises caused by switch-

ing the unit on or off. Gain adjustment

switches allow the gain of each channel to

be increased by +6 dB, if the output level

of the decoder, or other signal source is

found insufficient. There is also a cover

provided for these swiches to ensure that

the settings are not altered accidentally.

Two rack ears are included in the kit for

easy assembly of the DI8A into a stan-

dard 19 inch equipment rack.
