Volume Ch 1: Adjusting the level on this knob effects the amount of speaker driving signal power
exiting the Channel 1 speaker cable connector on the back of your Mod6G amplifier. This
control, whose input is parallel to the Volume Ch 2 control, allows for leveling control when
using different speaker loads and/or speaker cabinets with different sensitivities per channel.
Volume Ch 2: Adjusting the level on this knob effects the amount of speaker driving signal power
exiting the Channel 2 speaker cable connector on the back of your Mod6G amplifier. This
control, whose input is parallel to the Volume Ch 1 control, allows for leveling control when
using different speaker loads and/or speaker cabinets with different sensitivities per channel.
Limiter LEDs: These light emitting diodes on left and right of the "L" correspond respectively to the
power output Channels 1 and 2. The LEDs will illuminate when the the outputs of their
respective channels are have reached their headroom ceiling. Your Mod6G amplifier will
employ signal peak limiting circuitry to protect the amplifier and speakers from possibly
damaging waveforms resulting from pushing such high output levels, however operating the
amplifier at this output level is highly discouraged.
Thermal LEDs: These light emitting diodes on left and right of the "T" correspond respectively to the
power output Channels 1 and 2. The LEDs will illuminate when the amplifier has reached an
internal temperature that is too high for the integrated components to operate within their
specified temperature ranges. Your Mod6G employs thermal sensing technology to control the
variable speed fan in located inside the back panel. Under normal operating conditions, you
should not see the thermal LEDs illuminated. Should you see either or both of these LEDs
illuminated, turning down the Channel 1 and 2 Volume controls to minimum is advised to
allow the fan to cool down the internal temperature to safe levels.
Direct Injection: This XLR-type jack is where you can plug in an XLR-type cable to send your
amplifier signal to a mixing board for live sound P. A. support or for recording purposes. This
output on your Mod6G amplifier is transformer balanced, and sends your effected signal POST
6SL7 preamp gain stages, equalization stages, 6V6 power gain stages, output transformer, and
effects loop. This method ensures the most tone-accurate signal gets to the mixing board
without mic'ing your speaker cabinet. You or your sound engineer can still feel free to mic
your speaker cabinet, but this balanced output is handy for situations where transmitting a
signal isolated from environment acoustic modes, background noise, etc. is desired.
Power Switch: Your Mod6G amplifier incorporates relays and power circuitry to deliver voltage from
American standard single phase 120 volt 60hz AC wall jacks in a controlled, safe manner to
the circuitry inside the amplifier. When the switch is in the upward position, you will see
illumination coming through the Monarch Amplification laser-cut logo on the front of the
amplifier and the amplifier is on. The downward position for the Power Switch turns the
amplifier and internal illumination off. Your Mod6G amplifier does not employ a "standby"
switch found on many other tube amplifiers. A "standby" switch is not necessary on the
Mod6G amplifier, but waiting 5-10 seconds after turning on the amplifier to begin playing is
recommended to prolong tube life.
