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
16. POWER SWITCH: Toggle this switch to the ON position to turn on
each channel.

8. MID BOOST SWITCH: Toggle this switch to the ON position to
NOTE: Always turn the power switch ON FIRST, OFF LAST. Use the
Standby switch (toggled to the Standby position) when first turning
the amp on as well as during breaks.
boost the midrange response of Channel B.
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!

The VC-6112/6210/6212 is covered with a durable black Tolex® material. To keep the cabinet in top con-
dition, wipe it clean with a damp lint-free cloth to remove dirt and road film. Never spray cleaning agents
directly onto the cabinet, and stay away from abrasive cleansers which could damage the finish.
