Selecting Bridge Mode (See Diagram 12)
Under normal operation, this should be left in the 8 ohm position as illustrat-
ed in
Diagram 11
. It is sometimes desirable to combine two channels into
one through bridging. The output of the combined channels can then be
used to power one speaker.
To bridge two adjacent channels first make sure that the Impedance Switch is
in the 8ohm position. Next move the switch marked “BRIDGE” to the “ON”
position.
The speaker must be connected to the terminals immediately under the
“BRIDGED” text as indicated in
Diagram 12
. All input selection and settings
for the bridged channels will be done on the channel to the left.
Do not connect more than one speaker to the outputs of the bridged
channel.

Selecting Inputs (See Diagrams 9 & 10)
Each channel is capable of delivering the source from many inputs. The three
main inputs are BUS, AUX and LINE IN. The selection for these inputs is done
via the Input Selection switch, marked “BUS-AUX-LINE”. To select a source for
each channel, follow the steps below:
1. Select the desired source input. Set the Input Selection switch to BUS (will
play source connected to the BUS INPUT), AUX (will play source connect-
ed to the AUX INPUT) or LINE (will play source connected to the LINE IN).
2. The BUS and AUX inputs each have a left and right input. The left, right
or combined left and right signal from these may be selected via the
switch marked “R R+L L”. Select the side you want the channel to deliver.
Selecting “R” will play the right channel of the selected input. Selecting
“L” will play the left channel of the selected input. Selecting “R+L” will
play the combined signals of right and left.
Select the Impedance Setting (See Diagram 11)
CAUTION: The switch must always be set to 8
Ω
if the adjacent channels are
bridged.
For best results, if you will be using multiple speakers that will make the over-
all system impedance load drop to below 4 ohms at any pair of outputs,
make sure that the switch above the speaker inputs is in the 4 ohm speaker
setting. If the system impedance load will not drop below 4 ohms, leave it in
the factory setting of 8 ohms.
