21.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 out- side of the United States, see the area’s Crate dealer for the proper power cord or consult a local professional electrician.

22.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.

23.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 exam- ple). Connection to this jack interrupts the signal from the internal preamp to the power amp. The Preamp Out (#22) signal is not interrupted.

24.SPEAKERS: Use these jacks to con- nect 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 combina- tions resulting in impedance loads below 4 ohms. Use the chart below to help determine parallel loads. If in doubt, ask your dealer.

Cab Imp.	# Cabs	Total Imp.
8 ohms	2	4 ohms
16 ohms	2	8 ohms
16 ohms	4	4 ohms

25.BALANCED LINE OUT: Use this 3-pin XLR jack to send a line level signal to the house sound board or mixing con- sole. 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 switchable to be either pre or post EQ through the front panel Pre/Post switch(#11).

26.EFFECTS LOOP SEND: This unbalanced 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.

27.EFFECTS LOOP RETURN: This jack receives the signal from the output jack of an external effects processor. Use shielded cables with mono 1/4” plugs for connecting the Effects Loop.
