The Front Panel Controls and Their Use:  
1. INPUT JACKS: The High input is a direct connection for “stan-  
dard” electric guitars. The Low input is padded 6dB and is best  
suited for guitars with “hot” pickups or on-board active electronics.  
(Use a high quality shielded instrument cable.)  
10. BASS CONTROLS: These controls adjust the low end levels for  
each channel.  
11. MASTER CONTROLS: These controls govern the output volume  
levels of each channel.  
2. CHANNEL SWITCH: Toggle this switch to the desired channel: up  
for Channel A, down for Channel B. A footswitch also may be used  
to select channels, in which case this switch is bypassed – see  
#25, rear panel.  
12. REVERB CONTROLS: These controls govern the amount of  
reverb applied to each channel.  
13. PRESENCE CONTROLS: These controls govern the upper-high  
frequencies for each channel, allowing an enhancement to the  
sound beyond the Treble and Mid controls.  
3. GAIN CONTROLS: These controls govern the amount of signal  
going to the output stage of the amplifier. Channel A Gain offers a  
range of sounds from clean to a bluesy crunch; Channel B from a  
slight crunch to full tilt screaming distortion.  
14. POWER LAMP: This dual color jewel lamp glows when the amp is  
turned on – an amber color indicates Channel A, a red color indi-  
cates Channel B.  
4. BRIGHT SWITCH: Toggle this switch to the ON position to boost  
the upper register of Channel B.  
15. STANDBY SWITCH: Toggle this switch to the ON position to acti-  
vate the amplifier – once the power switch (#16) has been on for  
at least 30 seconds. (This allows the tubes to come up to a safe  
operating temperature before use.) The amp should be set in the  
Standby mode (switch down) during extended breaks to help pro-  
mote longer tube life.  
5. MID BOOST SWITCH: Toggle this switch to the ON position to  
boost the midrange response of Channel A.  
6. TREBLE CONTROLS: These controls adjust the high frequency  
levels for each channel.  
7. MID CONTROLS: These controls adjust the midrange levels for

9. LOW BOOST SWITCH: Toggle this switch to the ON position to  
boost the low end response of Channel A.

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.  
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”).  
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.  
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.  
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.  
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.  
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!
