Generally speaking, you'll probably end up with the Mid control in cut mode for most
problem solving uses of the Sweep control. In any case you will learn to use this feature
judiciously. The best P.A. EQ setting is the one with the least adjustment, but when you
need to solve a problem it is good to know how to use the tools.
8. Stereo Channel EQ
The VGM14's stereo channels feature 4-band Equalization with a control range of +/-15 dB.
The High EQ is shelving at 12.5 kHz, Low EQ shelves at 80 Hz, the High Mid EQ is centered
at 3 kHz, and the Low Mid EQ is centered at 400 Hz. The 4-band Equalization was carefully
selected to help achieve the best quality of sound for line level and stereo sources.
As with the Mono Channel EQ it is best to set the channel EQ during a sound check.
It is best to minimize the amount of EQ "boost" or "cut" you add to the audio. +/-15 dB
represents a considerable level change.
9. Mon (Monitor)
The Mon (Monitor) is the audio signal sent to the stage monitors for the musicians. This
control adjusts the level of signal from each channel to the master section's Mon fader.
The signal for the channel's Mon control is independent of the Channel Fader (pre-fader);
adjusting the Channel Fader will not affect your monitor mix.
Note: When feedback occurs, the cause is often the audio signals from the stage moni-
tors feeding back to the microphones. When this happens, the first thing to do is turn
down the master section's MON fader, this will make sure that the monitors (and not the
main P.A.) is the cause of the feedback. If the cause is the monitors follow these steps:
A. Turn up the master section's Mon fader until feedback is just starting.
B. Now turn down each channel's Mon control just a little, and then return the control
back to the original position. This will help you discover which control reduced the
feedback the most.
C. With that information, reduce the level on that particular control to the point of
no feedback. By using the Mon control, you will most-likely eliminate the feedback
without affecting that channel's level through the main P.A.
With the VGM14's independent monitor mix, it can be beneficial to assign the internal
graphic equalizer to the Mon output and use the graphic equalizer to help control feedback.
10. Aux (Auxiliary)
The Aux (Auxiliary) feature can be used to send audio for use as a 2 nd Mon (Monitor), a
2nd EFX, a additional subwoofer signal, or it can be used for a separate mix to be sent to
another piece of outboard gear. The switch, located beside the Aux level control, selects
either a pre-channel fader signal or a post-channel fader signal.
• In the Pre position, the audio signal is sent to the Aux mix before the signal is sent
to the channel fader. Since the channel fader does not affect the level of this signal
you can use the Aux control as a 2 nd Monitor mix.
• In the Post position, the audio signal is sent to the Aux mix after the channel fader,
this means the channel fader's level affects the signal set to the Aux mix. This behav-
ior allows the Aux control ideal for use as a 2 nd EFX mix, a separate Subwoofer signal,
or for use as a separate audio signal for a zone or other purpose.
Note: If used as a Subwoofer buss, the Aux control allows you to specify specific chan-
nels, such as the bass instrument channels, optimizing a clean well defined bass sound.
11. Digital Effects (EFX)
The channel EFX controls adjust the level of signal from each channel to the EFX Send
control. The signal sent to the EFX control comes from the Channel Fader (post-fader).
Adjusting the Channel Fader will change the level of the dry signal and the EFX signal.
The signal from the EFX Send control continues to the internal effects generator and to
the EFX Send jack, for use with an external effects unit.
