NOTE! When in HOT mode the tone controls still affect the sound slightly.
MASTER
9. TONE CUT Control
This circuit is placed in the power amp as opposed to the pre-amp section like the TREBLE and BASS
controls. What this does is the opposite of what you may expect. Turning it clockwise will decrease the
higher frequencies. Use in conjunction with the TREBLE control to fine tune the high end of your sound.
10. VOLUME Control
This controls the overall or MASTER VOLUME of your amplifier. Use in conjunction with the NORMAL
and TOP BOOST volume controls to find the perfect balance between pre/power amp distortion and out-
put volume.
11. MV/BYPASS switch
This switch allows you to completely remove the MASTER VOLUME control from the circuit. Giving the
tonal purist what they would expect from a vintage AC, but also allowing for lower volumes if needed.
OUTPUT Section
12. OP MODE Switch
This controls the output level of the power amplifier. When set to half power mode (15W AC30HW and 7.5W
AC15HW) the power amp distorts less and has a smooth high frequency roll off. When set to full power
mode (30W AC30HW and 15W AC15HW) the power amplifier breaks up at higher volumes and produces
a more harmonically dense sound.
13. POWER Switch
This is the ON/OFF switch for the amplifier. Please ensure the amplifier is switched off and unplugged be-
fore being moved.
Rear Panel
1. POWER OUTPUT jacks
This is where you can hook up an extension or external speaker cabinet(s) if desired.

EXTENSION SP: This speaker jack runs in parallel with the internal speaker which is 16 Ohms. The ex-
tension cabinet must be 16 Ohms and the IMPEDANCE switch should be set to 8 ohms.
EXTERNAL SP: This speaker jack will mute (disconnect) the internal speakers and you can hook up ei-
ther a 16 Ohm or 8 Ohm cabinet. Be sure to set the IMPEDANCE SELECT switch accordingly. (See “IM-
PEDANCE SELECT Switch”)
