Control Room/Source Blend
With this control you can adjust the relative levels between the Musician and
Mix and/or 2Tr signals for the control room monitor speakers.
Master Volume
The master volume potentiometer globally controls volume for the three
monitor speaker pairs. This analog control regulates the audio signal directly
to avoid any coloration/distortion typical of VCAs, DCAs, etc., which require
higher inter-channel tolerances and tend toward higher distortion figures.
Moreover, this potentiometer possesses an optimal rotational torque and
“feel” for precise hand control.
Tip: Speaker Calibration
The MTC dispenses with speaker output trims, as they would unnecessarily
stress the signal pathes—all active speakers and also power amps have input
trims.
The adjustment process should begin with the quietest monitor pair (smallest
sound pressure level) with the input sensitivity at maximum level.
Leaving the MTC Master Volume control as set, you then perform the same
adjustment for the other monitor/speaker pairs until each produces the same
sound level as the first pair. Lacking a sound pressure level meter, you may
still accomplish this adjustment well enough by ear.
