23. POWER CORD: Connect the male end

of this cord to a properly grounded AC

power outlet. Use only a grounded outlet!

DO NOT defeat the ground pin of the

cord! If the amplifier is used outside of the

United States, see the area’s Crate dealer for

the proper power cord or consult a local pro-

fessional electrician.

24. EFFECTS LOOP RETURN: When

using an external signal processor, the best

results will be obtained when the device is

connected to the amplifier’s effects loop for

virtually noise-free operation. This jack

receives the output signal from such a

processor

25. EFFECTS LOOP SEND: This unbal-

anced jack lets you send a signal out to an

external effects processor or tuner. The signal

at this jack is post-EQ, pre-Master. Connect

this to the input jack of the processor or

tuner. Use shielded cables with mono 1/4”

plugs for connecting the Effects Loop.

26. BIAMP LOW OUT: When used in

the biamp mode, this output connects to

the low frequency power amplifier. See

the section entitled “Using the Biamp

Capabilities” on pages 6 - 9 for details.

27. BIAMP HIGH OUT: When used in

the biamp mode, this output connects to

the high frequency power amplifier. See

the section entitled “Using the Biamp

Capabilities” on pages 6 - 9 for details.

28. PREAMP OUT: A pre-amplified line

level signal may be tapped from this jack for

sending to an external amplifier, powered

monitor, recording console, mixing board or

effects processor. This is an unbalanced,

mono 1/4” jack.

29. POWER AMP IN: A pre-amplified line

level signal may be sent directly into the bass

amp’s power amp (as when slaving two

amplifiers together, for example). Connection

to this jack interrupts the signal from the inter-

nal preamp to the power amp. The Preamp

Out (#28) signal is not interrupted.

30. SPEAKERS: Use these jacks to connect
the amp to your speaker cabinet(s). Use
heavy duty speaker cables with mono 1/4”
plugs. These jacks are wired in parallel. Don’t
use cabinet combinations resulting in imped-
ance loads below 4 ohms. Use the following
chart to help determine parallel loads. If in
doubt, ask your dealer.

31. BALANCED LINE OUT: Use this 3-pin

XLR jack to send a line level signal to the

house sound board or mixing console. The

level of the signal at this jack is determined by

the setting of the Line Out Level control on

the front panel (#10). This signal is switch-

able to be either pre or post EQ through the

front panel Pre/Post switch(#11).
