29 . Bridge Select

The "Bridge Select (Sel)" terminals are the
access point to activate the "Bridge In / Out"
feature. To activate the feature connect the two
points together via an external contact closure.
These two points must be connected to send
or receive any signal. By connecting the Bridge
In / Out terminals of the Mixer amp, a simple
room combining system can be accomplished.
If using a remote switch and closing it, the
"Bridge Select (Sel)" will combine the amps
as one, opening the switch will separate the
amps.
Note:

If combining 3 or 4 Mixer amps
together the output level will have to be
adjusted before and after Bridge Sel terminals
are connected (shorted) together. We suggest
utilizing the Remote Level control when using
this feature.

30 . BRIDGE IN/OUT

Certain installations have the need to combine
one or more Mixer amps together. These Mixer
amps may operate different rooms of an install
but have the need to share a page or music
throughout the installation. These terminals
provide a way to send and receive balanced
line level signals from the internal mix bus of
the Mixer amp. The "BRIDGE IN / OUT" feature
is PRE Tone Controls and Low Cut Filter The
Bridge In/Out feature allows you to send and
receive a balanced signal. This is important for
allowing longer distances between the mixers.

Note: This function should only be used with
other Quest Sound mixers that have this
feature. The Send and Receive signals are
combined through the same terminals. To
activate this feature, see number 19 Bridge
