4Output connections

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.The Speakon connector for Channel A also contains contacts for Channel B out put as well (see Operation Modes).

5Ground lift switch

The recessed two-position ground lift switch is used to isolate the 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. Never lift the ground prong on the AC connector.

6Input connections

Input signals can be connected to the amp via the Combi connec- tors, the 1/4” TRS connectors, and the Female XLR (pin 2 hot) con- nectors. See Connections

Never connect a speaker of LESS		a
than 2Ω minimum impedance to an
individual channels’ output connections
when operating in STEREO or PARAL-
LEL mode.
Never connect a speaker of LESS
than 4Ω minimum impedance to
Channel A and B “+” output connec-
tions when operating in BRIDGE
mode. In BRIDGE mode operation, the
amplifier can produce output voltages
exceeding 120VRMS. Use extreme cau-
tion.
Never connect a hot	a
(red) output to ground
or to another hot (red)
output!
In situations where an UNBAL-		a
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.

7Mode selector switch

This recessed, three position switch configures the amplifier for Stereo, Parallel or Bridged Mono operation. The default factory setting is Stereo. See - operation modes.

a

Do not adjust the mode selection switch while the amplifier is turned-on.

8Input sensitivity switch

This three position switch allows the user to select the input sensitivity to .775v (0 dBu), X20, or X40 for full rated output power.The default factory setting is X20.
