Send Level Control; Loop Select Rotary Control; Slave Level Control; Speakers - Mesa/Boogie Dual & Triple Rectifier Solo Heads Owner's Manual

REAR PANEL:
NOTE: We suggest that when using the power section only of either the DUAL or TRIPLE RECTIFIER Solo Head, that you
have the amp switched to the Vintage Orange channel and the Channel Cloning switch set to 'Normal'. This assures a more neutral
power sensitivity thus making both versions more friendly to use as a power amp.
This is the master SEND LEVEL Control for the parallel Effects Loop. The inclusion of this control makes it

information regarding SEND LEVEL.
This 5 position rotary type switch determines the status of the Effects Loop. The Loop can be assigned to

either the DUAL or TRIPLE RECTIFIER Solo Head as a master pre-amp, or additional power amps may be connected for
more power when needed. Some players use this to derive an FX Send Signal and go to other amps for their wet
sound.
NOTE: Once a signal is taken from the Slave, it can not be inserted back into the FX Loop Return jack or a

feedback loop will occur. Much like holding a microphone into the PA system's cabinets...a loud high pitched
squeal will occur.

time insuring that you will not overload your processors' INPUT stage with an incompatible signal strength.
For the best results, try this method:
1.) Set up the VINTAGE and MODERN channels to your preferred Gain and Tone control settings.
2.) Adjust the individual channel MASTER Controls to the desired listening level.
3.) Set the Rear Panel Effects Loop SEND LEVEL Control so that your processors' INPUT indication

switching devices by connecting the EXTERNAL SWITCHING jacks and selecting EXT. SW. on the Loop
Select rotary. As you might surmise, the ORG. AUTO position assigns the Loop automatically to the
VINTAGE / ORANGE Channel and every time the ORANGE Channel is called up, the Loop will be engaged.
RED AUTO duplicates this scheme for the MODERN / RED Channel. For you purists, both the DUAL
and TRIPLE RECTIFIER Solo Heads gives you the ability to remove all Loop circuitry from the signal
path completely by selecting the BYPASS LOOP position.
This 1/4" jack and control provide a signal derived from the speaker jack. Perfect for using
RECTIFIER Solo Heads are not very sensitive to speaker mismatches and will not be
damaged by them, except that very low ohmage loads will cause the power tubes to wear
4 OHM faster. A single twelve-inch 8 Ohm speaker should generally be connected to the 8 Ohm
output. When using two 8 Ohm speakers, connect them both to the 4 Ohm outputs provided
(because the total load is 4 Ohms in that case.) Check out the information further back in
this manual regarding speaker impedance and possible speaker hook-up schemes.
