O PE RATING MO DE SWITCHE S
There are 3 different operating modes switchable for the CPD
series ampli昀椀ers.
STEREO - Each channel remains independent. The amplifier
may be used for two different signals.
PARALLEL - This setting connects both inputs together. One
signal feeds both channels. Each channel's Gain control and
loudspeaker connection remain independent.
BRIDGE - This setting combines both channels into a single
channel with twice the output power. Use only the 昀椀rst channel's
input and Gain control. Set the second channel's Gain control at
maximum. The load must be rated for the higher output power.
O UTPUT WIRING
The CPD Series employ Speakon output connectors. Ensure
that only heavy gauge two conductor speaker cables with
professionally wired Speakon connectors are used for
connection from ampli昀椀er to loudspeaker.
STEREO and PARALLEL Mode- Connect each loudspeaker to
its own channel of the ampli昀椀er, as shown on the left side of the
Speakon. The Mode 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 switches must be set for
Bridge Mode. Connect the load as shown on the left side of CH 1's
Speakon.
WARNING: Do not use less than 4 ohm load in Bridge Mode!
WARNING: Note polarity of connection for Bridge Mode.
OUTPUT WIRING WARNING: Class 2 wiring shall be used.
For Bridge Mode, class 3 wiring shall be used.
OUTPUT SAFETY WARNING: Make all connections with
ampli昀椀er turned off. Risk of hazardous energy!
Q UICK START G UIDE
1. Make sure that the power switch is set at the OFF position while making connections to and from the power ampli昀椀er.
2. Connect all devices in the signal path and ensure that each connection is secure.
3. Set all level and gain controls to their minimum.
4. After powering up all other devices 昀椀rst, turn on the CPD ampli昀椀er and verify that the POWER LED is illuminated.
5. Turn the ampli昀椀er volume control up to the 3 o'clock position. (This setting can be adjusted higher or lower, as needed,
after set-up). With source signal present starts to set each gain stage in your signal path, starting at the beginning of
the chain. It is best practice to make overall volume changes with the master fader of your mixing console once the
ampli昀椀er input trim has been calibrated.
6. When powering down, make sure that the power ampli昀椀ers are switched off 昀椀rst.
