The Rear Panel:

17. AC LINE IN: Firmly plug the female end of the supplied

power cord into this socket, pushing it in until it is fully seat-

ed. Plug the male end of the cord into a properly grounded

AC outlet of the correct voltage. DO NOT DEFEAT THE

GROUND PIN OF THE AC PLUG! Use only the supplied

power cord. If the amplifier is to be used outside of the

United States, see your authorized Crate dealer for infor-

mation about alternate line cords and power converters if

needed.

18. FUSE: This fuse protects the amplifier against damages

caused by overload conditions in the unit. If the fuse blows,

replace it only with the same size and type as indicated on

the rear panel. If the fuse blows continually, the line voltage

may be incorrect, or the amp may need servicing.

19. BIAS ADJUST / BIAS TEST POINT: For qualified

Service Personnel only! (All others please just ignore

these internal Bias adjustment potentiometers.)

20. IMPEDANCE SWITCH: For the best performance and

least strain on the amp, you MUST match the amp’s imped-

ance to that of your speaker cabinet(s). Set the selector

switch to the 8 or 16 ohm position, depending on the total

impedance of your cabinets. The chart below can help you

determine that impedance based on the following combi-

nations of speakers connected in parallel.

CAB IMP. # OF CABS TOTAL IMP.

16 ohms 2 8 ohms

32 ohms 2 16 ohms

32 ohms 4 8 ohms

21. SPEAKER JACKS: The amplifier is shipped from the fac-

tory with its internal speaker connected to Main speaker

jack. An second cabinet may be connected to the Ext. jack,

as long as the Impedance switch (#20) is properly set. If an

external speaker cabinet is to be without the internal speak-

er, uplug the internal speaker cable from the amplifer and

connect the external speaker to the Main jack. (When

reconnecting the internal speaker, be sure to use the Main

speaker jack!

22. EFFECTS LEVEL CONTROL: Use this knob to set the

input level of the signal from the Effects Loop Return jack

(#23). The Effects Loop Send level is adjusted by the

Master volume controls (#11).

23. EFFECTS LOOP RETURN JACK: Connection from an

external effects device is made via this jack. Connect a

shielded instrument patch cord from the output jack of the

effect to the return jack. The return jack also doubles as a

"power amp in" jack, to feed a line-level signal directly into

the internal power amp. This is useful when "slaving" two

amplifiers together. When using in this mode (slaving),

make sure the front panel Master volume controls are all

the way down (at “0”).

24. EFFECTS LOOP SEND JACK: Connection to an external

effects device is made via this jack. Connect a shielded

instrument patch cord from the send jack to the input jack

of the effect. The send jack also doubles as a "preamp out"

jack, to feed a post-eq signal to a mixing board, recording

console or external amplifier.

NOTE: Effects loop operation is parallel with the signal

path. Mix controls on the effects should be set to 100% (full

wet). If no effects are connected to the Effects Loop, the

Effects Level control (#22) acts as an extra volume boost

which can be activated by the footswitch. For the best sig-

nal to noise ratio when NOT using the effects loop, keep

the Effects Level control (#22) set to “0”.

25. FOOTSWITCH JACK: Connect the supplied two button

footswitch for control of channel switching and the effects

loop on/off. The tip of the jack is for channel switching; the

ring is for effects. When a footswitch is connected here, the

front panel channel select switch is disabled.
