(1) POWER SWITCH
This two-way toggle switch applies mains power to the
unit. The red POWER STATUS LAMP (3) will illuminate
when this switch is in the ON position.
(2) STANDBY SWITCH
This two-way toggle switch allows the amp to be placed in STANDBY mode. In the STANDBY position
the tubes stay hot but the amplifier is not operational. Switching to the ON position places the amp in
active mode.
(3) POWER STATUS LAMP
This indicator illuminates when mains power is being supplied to the amp.
(4) PRESENCE
This is used to fine-tune the high frequency range of the speaker enclosure by varying the damping
factor of the amplifier at high frequencies.
(5) RESONANCE
This is used to fine-tune the low frequency range of the speaker enclosure by varying the damping
factor of the amplifier at low frequencies.
(6) MASTER VOLUME
This control sets the overall volume level of the amp. Once the desired balance between the three
channels in the amplifier has been achieved, the entire output level of the unit can be increased or
decreased by rotating this control. Clockwise rotation increases the level; counterclockwise rotation
decreases the level.
(7) MASTER REVERB
This controls the overall reverb level.
