it disables the Instrument and Aux/Mic inputs. Therefore, they
cannot be used in conjunction with the Stereo function.
PHASE SWITCH
A Phase switch is provided for each channel to help eliminate
feedback and other phasing problems. In the OUT position, the input
and outputs are normal (in phase). Pushing the switch IN reverses
the phase. If you are experiencing early feedback with an acoustic
instrument, try using the Phase switch to alleviate the situation. As
well, remember that your position on stage can influence when
feedback can occur. Always start out with the Phase switch in the
normal (out) position.
PHANTOM POWER SWITCH
Pushing this switch in provides nine-volts DC to the Aux/Mic input
jack or to the Ring of the Stereo jack. This voltage is slightly higher
when using the optional A/C adapter. Activate this function ONLY
when you are using a soundhole mic or other device needing 9 volt
"phantom power". Engaging the Phantom Power Switch with nothing
plugged into the Aux/Mic or Stereo input jack, will effectively reduce
battery life. ALWAYS check the position of this switch BEFORE
turning on the Master Blender. If you need phantom power, push the
switch in after your connections are complete.
GAIN CONTROLS
Each channel is supplied with an individual Gain Control. It affects
the level going to your tone controls, and all output jacks. Once you
have set your Gain to a desired level, use the Master Volume for
"live" adjustments. This will avoid changing the level at the XLR
direct out.
Start with the Gain control at about the 10 o'clock position. Then
adjust your tone contols to their desired settings. Adjust the Volume
to a comfortable listening level. Boost the Gain until you hear some
distortion or "clipping" upon striking a loud note or chord (depending
on the output level of your instrument, this may not occur). Now,
lower the Gain control just below where the distortion disappears.
Use the MasterVolume to set your overall volume. This allows you
the maximum signal to noise ratio the Master Blender has to offer.
Remember that boosting any one of the tone controls can affect the
optimum position of the Gain Control.
TONE CONTROLS
Individual Bass, Midrange, and Treble controls are provided for each
channel. The "flat" position, or where the controls have no effect, is
when the pointer is straight up (12 o'clock). Turning the control
clockwise from the flat position boosts the tone control, counter
clockwise cuts the tone control. Cut or boost is a maximum of 12 dB.
The Bass is centered around 80 Hz, midrange is set at 800 Hz, and
the Treble boosts at 3 KHz. The bandwidth of each control is
different, and set to be
musically pleasing.
