left, positions 1 and 2 dip the midrange in two different places giving you two amazing choices for classic round, warm R & B sounds.
Turning right past the 12:00 noon FLAT position unveils two variations on the mid-bump theme. Positions 4 & 5 boost adjacent mid
regions to create two powerful mid-focused sounds that push articulate fingerstyle playing to the forefront of any mix or add the tight
drive to Rock. Great Tone doesn't get any simpler!
The Front Panel MASTER control makes adjusting your playing volume levels quick and easy on stage. A TUNER MUTE pull pot is
added to the MASTER Output control for silent tuning in live or studio applications. This feature can also be triggered remotely from
the included Footswitch.
The Rear Panel follows suit with simplicity dictating the layout of the essential features every pro rig should include. Tucked securely
between the intake/exhaust vents sit the SPEAKER OUTPUTS, the FOOT SWITCH jack and the VOICE DEFEAT switch.
The SPEAKER OUTPUTS utilize stage ready SPEAKON UNIVERSAL connectors which accommodate both standard ¼" phone type
and Nuetrik SPEAKON locking plugs. A SPEAKER IMPEDANCE switch keeps things in the Output section properly matched and
allows you to select between 8/4 Ohm loads or switch down to 2 Ohms (CRITICAL when loads of 2 Ohms are used) for full power
with these low load settings.
The FOOTSWITCH jACK located under the SPEAKER OUTPUTS is a standard ¼" stereo female jack that accepts the supplied
stereo Footswitch Cable. The Footswitch allows you to control the Graphic EQ and the Tuning Mute function from the front of the
stage or other remote location during performance.
The M9 includes a VOICE DEFEAT feature that works in conjunction with the Footswitch and allows you to automatically defeat the
Front Panel VOICE modes when you engage the Graphic EQ via the Footswitch. The choices are VOICE ACTIVE (toggle up) and
VOICE DEFEAT (toggle down).
In the VOICE DEFEAT position the VOICE circuit will automatically return to a flat/bypassed state (same as position 3) whenever the
Graphic is engaged at the Footswitch, regardless of where you have the VOICE control set. This prevents redundant "doubled-up" or
"contradictory" application of the EQ and ensures the maximum shaping power of the Graphic EQ will be achieved. It also allows you
to have a second Footswitchable sound that is truly different and unique from that which you have dialed up on the Front Panel.
In VOICE ACTIVE (switch up) the VOICE mode you have engaged on the Front Panel will remain active when you trigger the Graphic
EQ "on" from the Footswitch. When using this setting, be aware of the pre-existing EQ curve of the VOICE mode called up – and
try to use the Graphic for subtle enhancement of frequencies other than those already most affected by that VOICE mode. Don't be
surprised if the Graphic EQ seems a little less powerful when you apply it to an "already EQ'd sound" that includes one of the VOICE
modes.
NOTE: For the maximum Graphic EQ control over the sound when the Footswitch is not in use, defeat the VOICE feature manually
from the Front Panel by selecting the "Bypassed" position "3" on the VOICE rotary control when the Graphic EQ is in use (ON). This
way you will not be "EQ-ing an already EQ'd sound" which can diminish the effectiveness of the 9 Band EQ.
The TUNER OUT jack will feed a signal to your outboard tuner and you can use the Front Panel PULL MUTE feature located on
the MASTER control to mute the signal for silent tuning. The MUTE can also be remote triggered by the Footswitch. The EFFECTS
LOOP is wired in series with the main signal. Insert your favorite processor(s) here with the SEND feeding the INPUT of the device
and the RETURN connected to the OUTPUT of the device.
To the right of the air intake vent are the EFFECTS LOOP and DIRECT OUTPUT sections. The DIRECT OUTPUT consists of a
standard 3 pin male XLR jack and a ground lift for the circuit-to-chassis ground connection. Leave the switch set to GROUND (switch
down - circuit grounded) unless you experience hum when connecting to a live sound board or studio recording console in which case
try the LIFT position to eliminate the hum caused by the two different references to ground.
That wraps up our Overview of the controls and features of the M9 CARBINE and now we're ready to look at the controls and their
individual roles in creating the sounds you hear in your head. Once again, thank you for choosing Mesa and most of all Enjoy!
