Speakers can be connected via the high current binding posts and
the industry-standard Speakon (NL-4) connectors.
Binding posts: One pair (Red- hot, Black- ground) per channel.
Speakons - One connector for each channel. In Bridged Mono
mode, the Speakon connector for Channel A is used exclusively
(see Operation Modes).
5 Ground lift switch

amp’s signal ground from the chassis/AC ground.The factory default
setting is to the right, Grounded.To lift, or disconnect the signal
ground from the chassis/AC ground, slide the switch to the left.
In situations where chassis ground must be lifted, use this switch -
never lift the ground prong on the AC connector.

Input signals can be connected to the amp via the Phoenix connec-
tors, the 1/4” TRS connectors and the Female XLR (pin 2 hot) con-
nectors. Input sensitivity is .775v (0 dBv) for full rated output
power. See Connections

In situations where an UNBAL-
ANCED signal is fed to the amp, it’s
important to ground the unused
input. If the inverting (-) input of an
amp channel is left floating, the chan-
nels gain will drop by 6 dB. In effect,
the amp will not be as loud. For more
information about this, ask your dealer
or contact Crest Audio Technical
Support directly.
