YORKVILLE PGM8 Manuel De L'utilisateur page 7

With the PGM8's independent monitor mix, it can be beneficial to connect a graphic
equalizer between the MON output and the monitor amplifier (external amplifier or
powered speakers, depending on how you have it set up) and use the graphic equal-
izer to control feedback.
8. Digital Effects (EFX)
The channel EFX control adjusts the level of signal from each channel to the EFX Send
control. The signal for the EFX control comes from the Channel 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.
Alternatively, if you do not require any effects at all, the signal at the EFX Send jack
can connect to the input of an additional monitor system or another amp/speaker sys-
tem via the EFX Out jack using a standard balanced patch cord. In this case, the EFX
controls would act as send controls to achieve a semi-separate mix. Remember that
the Channel Fader level controls also affects this signal.
9. Pan Control (Mono Channels)
This controls the post Channel Fader signal routing to the Main fader through the
main bus. In the Pan Control, the signal levels are compensated at the L&R rotation
extremes so that panning during a performance will result in minimal sound level
change in the center-field audience areas.
In audio terminology, a bus is a mix-down channel where all the signals from the input
channels are blended into one signal. The PGM8 has 5 busses: MAIN (left and right),
MONITOR, EFFECTS and RECORD OUT
10. Balance Control (Stereo Channels)
This controls the stereo channel signal routing to the Main Fader. Similar to the Pan Con-
trol, the Balance Control can shift the center image between the left and right channels.
11. Mute Switch
Each channel's Mute Switch mutes that channel's left, right, and all of its sends signals. The
Mute function is a timesaving feature that enables you to mute channels without turning
down the Channel Fader that you preset during the sound check.
It's important to mute all unused channels during a performance as open microphones
increase the possibility of feedback, and can made a music mix sound muddy.
12. Clip/Mute LED
The Clip LED turns on at 3 dB below the channel's actual clipping level and with the
Clip LED threshold set below actual clipping level, it is possible to allow occasional
light activity without worrying about distortion. As a result, you may use the Clip
LED to help you adjust the proper gain with the Channel Fader control. When the Mute
switch is depressed, the Clip LED will illuminate at half–brightness to indicate the mute
condition but will still flicker to indicate clipping.
13. Channel Fader
The Channel Fader control's taper is expanded in the upper mid-slide area for pre-
cise volume adjustments and condensed at the extremes allowing you to increase or
decrease the audio level quickly. The audio out of the Channel Fader goes simultane-
ously to the channel EFX, and Pan controls.
