LEVEL CONTROL:

This lonely knob is the DC-10's final output knob or overall master. After the relative balance of the two
channels has been set with the channel MASTER controls, use the LEVEL control to increase or decrease the listening volume. It is

POWER: 60 / 100 WATT: The DC-10 may be used in a 100 WATT (Full Power) configuration or can be switched down to a 60
WATT (Half Power) harness for smaller venues, added power clipping possibilities or, simply for different sonic characteristics. The
100 WATT position sounds fuller and richer with more defined bass response.

The 60 WATT position leans towards a more bubbly, brighter sound that can be pushed more easily for power clip
overdrive. The 60 WATT position shuts down the two center power tubes, keeping them in stand-by mode for instant
power increases and may be switched while the DC-10 is in operation. If you prefer the sound of the 60 WATTposition
you may feel free to use it all the time with no penalty. You may then swap the two center 6L6's for the outer pair in 6 -

failure, you may pull the faulty tube(s) and run the DC-10 with only the outside pair until you can replace the faulty
tube(s). If you ever have to resort to this procedure, be aware that you will notice a slight hum, but don't worry...it won't hurt your
amplifier at all and will cease when you have replaced the center pair with two good tubes.
NOTE: To obtain the maximum headroom for clean sounds when using the DC-10 in the 60 WATT position, it is recommended that
you remove the speaker cable from the 16 ohm jack and connect it to the 8 ohm jack. This is not mandatory, but will insure the best
impedance match giving you the maximum power. If you prefer the sound of the 16 ohm jack or wish to clip the DC-10 at reduced
volume levels...by all means leave the speakers connected to the 16 ohm output.
ON / STANDBY:
Perfect for set breaks...this toggle switch also serves an even more important purpose. In the STANDBY
position the tubes are at idle so that during power up they may warm up before being put to use.
ON
Before POWER is switched ON, make sure the STANDBY switch is in the STANDBY position. Wait at least 30
seconds and then switch the STANDBY to the ON position. This prevents tube problems and increases their toneful
life substantially.

This switch delivers the A.C. POWER to the DC-10. Make sure the unit is grounded (All three terminals of the
A.C. POWER:
A.C. cord should be connected whenever possible) and that the proper voltage is present. Follow the cold start
ON
procedure as described in the ON / STANDBY section above when powering up. The total power consumption
for the DC-10 is 3 Amps @ 117 Volts. Thus, a 15 Amp circuit (which is what most house circuitry is wired with)
is adequate. Make sure the Euro style A.C. POWER cord is firmly seated in the power receptacle before
powering up the unit.

also the Effects Return Level control, a point we thought you should know. This design
element makes processor interfacing a lot easier and gives you one less knob to deal

with when you want to adjust your overall playing volume in performance situations.
Optimum setting depends on the size of the room you wish to rock, but generally the
DC-10 sounds best with a setting somewhere between
LEVEL control.
