SELECTING STEREO, PARALLEL, OR BRIDGE MODE
The amplifier can be set for normal Stereo operation, Parallel input Mode, or
BridgeMono Mode.
Stereo Mode -Each channel remains independent. The amplifier may be used
for two different signals.
Parallel Mode - This setting connects both inputs together. One signal feeds both
channels. Each channel's Gain control and loudspeaker connec tion remain independent.
Bridge Mode - This setting combines both channels into A single channel with twice
the output power. Use only the first channel's input and Gain control.
Do not connect different inputs to each side of a channel pair
when operating in Parallel or Bridge Mode.
.
XLR INPUTS
Each channel has a balanced 3-terminal XLR input. Inputs are
connected with standard cables and can be changed quickly. Pinouts are
marked on the rear panel and shown in the illustration.
The input impedance is 20k ohm balanced or 10k ohm unbalanced.
Balanced connections are recommended to reduce AC hum and interference,
especially with long cable runs. Unbalanced connections may be suitable for
short cables. The signal's source impedance should be less than 600 ohms.
OUTPUTS
Wiring connections are shown on the back of the chassis.
BINDING POST OUTPUTS
Stereo and Parallel Mode: Wire as shown by loudspeaker symbols 1 and 2.
Bridge Mode: Wire as shown by Bridge Mono loudspeaker symbol.
SPEAKON OUPTPUTS
Each channel accepts a normal 2-wire cable. In addition, Channel1accepts
4-wire cables for single cable stereo or (bi-amp)connection.
OUTPUT TERMINAL SAFETY WARNING!
Do nottouch output terminals while amplifier power is on.
Make all connections with amplifier Turned off. Risk of h
azardous energy!
Stereo and Parallel Mode-Connect each loudspeaker to its own
channel of the amplifier, as shown on the left side of the chassis label. The
Mode configuration switches must be set for Stereo or Parallel Mode.
Bridge Mode-Bridge Mode configures the channel pair to drive a single
audio circuit. The Mode configuration switches must be set for Bridge Mode.
Connect the load as shown on the right side of the binding posts or to the
left on Channel 1 s Speakon. 4 ohms is the minimum impedance for
Bridge Mode use.
Do not use less than 4 ohm load in Bridge Mode!
Note polarity of connection for Bridge Mode.
OUTPUT WIRING WARNING:
CLASS 2 WIRING SHALL BE USED. FOR BRIDGED MONO MODE,
CLASS 3 WIRING SHALL BE USED.
