The Mission
Monarch Amplification is founded on passion, focused toward the future of live sound
production. My mission is to bring forth technologically advanced solutions, each specifically
engineered to perfectly satisfy a set of requirements for the modern touring musician. I do not believe in
false claims, hocus pocus marketing, or fudged specifications. Each product shipped from Monarch
Amplification has my personal guarantee of quality and is conceived, engineered, troubleshot,
manufactured, and supported in the United States with as many American-made parts as possible. The
Monarch brand brings together pure and classic, hand-wired, single-ended, class A tone, and then
bootstraps it to a super high efficiency, class D power generation engine. Players gain features they have
never accessed before, such as post-tube-power effects looping, volume-decoupled 6SL7 and 6V6 tube
distortion, and post-power tube transformer balanced XLR DI. Each amplifier is a quality focused,
feature-packed, 1500 watt, sonic euphoria machine in a 15 pound package. You should expect the best
when you go with Monarch, because what you get is The Monarch of all Amplification Rigs.
I sincerely thank you for purchasing your Mod6G amplifier. I am sure you will find many years
of excitement and enjoyment playing through it. I stand behind my products proudly, and am happy to
answer any questions that you might have, directly. Feel free to contact me via the contact page on
www.monarchamp.com, even if you just want to make a comment.
Sincerely,
Kevin J Wehrle
President/Engineer

Front Panel
Input: This guitar signal input impedance is ~ 1 Megohms. Input and interstage wiring utilizes
shielded conductor to minimize radio frequency interference and noise.
Gain: Adjusting the output level on your guitar or utilizing a volume pedal between your guitar and
the input jack of your Mod6G controls the amount of signal that enters the first 6SL7 preamp
gain stage. The Gain control on your Mod6G controls the amount of signal that enters the
second 6SL7 preamp gain stage as well as the amount that enters the 6V6 power gain stage.
This control is used to alter signal to produce tones from clean to heavily distorted.
Low: Adjusting the level on this control effects the low frequency signal level on your Mod6G
amplifier. This is a passive, shelf-type equalization circuit that dynamically effects the output
level of frequencies between 0hz and 200hz. This control interacts with the Mid and High
controls to alter the effected low frequency range of the shelf.
Mid: Adjusting the level on this control effects the middle frequency signal level on your Mod6G
amplifier. This is a passive, subtractive circuit centered around the 600-800hz range. This
control interacts with the Low and High controls to alter the effected middle frequency range.
With Low and High controls set to minimum, the Mid control functions as an overall signal
level control governing how much signal the 6V6 power tube receives.
High: Adjusting the level on this control effects the high frequency signal level on your Mod6G
amplifier. This is a passive, shelf-type equalization circuit that dynamically effects the output
level of frequencies between 1Khz and 20Khz. This control interacts with the Low and Mid
controls to alter the effected high frequency range of the shelf.
FX ON/FX OFF: This switch enables or disables the post-power effects loop on your Mod6G
amplifier. When in "on" position, the effects loop is active. When in "off" position, the effects
loop circuit is completely bypassed.
FX Level: Adjusting the level on this knob effects the amount of signal passed on through the effects
send jack and to any effects units connected through the effects loop on your Mod6G amplifier.
FX Send: This jack is where line level effects pedals or studio effects rack units should be connected to
your Mod6G amplifier. Connect their inputs here.
FX Return: This jack is where line level effects pedals or studio effects rack units should be connected
to your Mod6G amplifier. Connect their outputs here.

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.

Back Panel
Fan: Your Mod6G amplifier utilizes temperature-controlled variable speed fan technology to cool
the components inside the amplifier.
Channel 1 Speaker Jack: This combination jack corresponds to the Volume Ch 1 control on the front
panel of your Mod6G amplifier. Connect to this jack with twist-locking or 1/4" speaker cables
to deliver power to your speaker cabinet. This output jack allows 8 ohm operation at 300 watts
RMS, 4 ohm operation and 500 watts RMS, and 2 ohm operation at 750 watts RMS. *Note:
While 2 ohm operation is permitted, a minimum 4 ohm load is recommended to maximize
peak power and thermal headroom.
Channel 2 Speaker Jack: This combination jack corresponds to the Volume Ch 2 control on the front
panel of your Mod6G amplifier. Connect to this jack with twist-locking or 1/4" speaker cables
to deliver power to your speaker cabinet. This output jack allows 8 ohm operation at 300 watts
RMS, 4 ohm operation and 500 watts RMS, and 2 ohm operation at 750 watts RMS. *Note:
While 2 ohm operation is permitted, a minimum 4 ohm load is recommended to maximize
peak power and thermal headroom.
Breaker: Your Mod6G incorporates internal self-resetting breaker technology for the vacuum tube
electronics portion of the amplifier, and also a resettable master power input breaker located
here on the back panel of the amplifier to protect the internal circuitry from power surges or
peak current overdraw.
Power Jack: Your Mod6G uses a standard 120 VAC 60hz plug found on other common electronic
devices such as computers, televisions, etc. A sufficient power cable for use here has been
included in the shipping materials with your amplifier.
