BALANCED OUTPUT / BALANCED LEVEL (Continued)
going directly into the console with no alteration from the M-2000. Sometimes this is preferred when
playing venues with large sound systems that have plenty of low frequency
power of their own and don't always need the added shaping that is happening
on the stage.
The BALANCED LEVEL control enables you to match the optimum levels
required by most mixing consoles. It is always good practice to "zero out" the
level on the M-2000 before connecting it to a console, just in case the channel
at the console was last used for a weak signal and is set to extremes.
NOTE It is NOT necessary to connect a speaker load to the M-2000 when using the BALANCED OUTPUT for recording or
live use. No damage to the amplifier will occur from having no load connected. Simply turn the OUTPUT LEVEL (located in the
center, bottom portion of the Front Panel) to 7:00 (this would be the Off position for this control.)
NOTE In certain situations a hum or buzz may occur when using the direct BALANCED OUTPUT. This occurs due to different
references (impedance) to ground between the M-2000 and the console. If this occurs you may want to lift the M-2000 ground
path by either using an XLR Ground Lift Adapter or by simply making a cable with the grounds disconnected. You might also try a
simple A.C. Ground Lift ( 3 to 2 adapter ) on the M-2000's power cord just to make sure the noise that you are experiencing is
not A.C. Ground related.

will not be accidentally removed during a performance. Depress the catch on the plug when removing the
foot controller's cable from the amplifier.
The M-2000 has an advanced way of

EFFECTS LOOP

dealing with signal processing. You may
choose not only how much of a given effect you wish to blend
with the dry signal, but also which frequencies will receive
processing! The loop is wired in parallel with the direct
signal, ensuring that your tone stays bold and authoritative.
It is comprised of a SEND and a RETURN that appear as a pair of 1/4 inch jacks
forming a bridge between the pre-amp and power sections of the M-2000.
These are then fed to the crossover circuit, allowing you control of the
frequencies that you wish to apply signal processing to, via the CROSSOVER
rotary control. To either side (and slightly below this rotary control,) you will see
LOW and HIGH. When this control is swept to the left toward the LOW
position, the low frequencies will be the primary ones that receive
processing.
This 6 pin XLR jack accepts and powers the M-2000 FOOT
CONTROL unit. It uses a locking type jack so that the foot controller
