Yorkville VGM14 - Manuel (Page 13)

To start, select the channels you desire effects on (vocals, lead guitar, brass
instruments and keyboards - most likely not on the drums or the bass guitar). During
the sound check, turn up the EFX Send control level to 5. On the channels that you
want effects, turn the EFX control up about halfway; turn up the Channel Faders to
about 0dB. Now dial in one of the sixteen desired effects, the simplified list of the
presets is located at the top of the mixer.
Next, position the ‘EFX - Return to Main’ fader (main sliders) to 0 dB. Turn up the MAIN
fader to a moderate listening level for previewing. Adjust the ‘EFX Return to MAIN’ control to
increase or decrease the effect’s intensity in the main mix. Similar to the ‘EFX Return to MAIN’
control, there is an ‘EFX to MON’ control for adding effects to the monitor signal if desired.
4. Internal Digital Effects Generator
The VGM14 includes an onboard, 24-bit, digital effects generator with 16 versatile presets.
Use the EFX selection control to choose from the 16 presets of different effects such as
reverb, echo, chorus, flange as well as a rotary speaker. There’s an acoustic guitar effect to
enhance the quality of sound from an acoustic guitar’s piezo pick-up. The ‘EFX Modify’ con-
trol allows you to adjust the selected effect for an almost unlimited number of variations.
Similar to the audio compressor on the input channels, there’s an audio compressor
used for the audio signal sent to the internal effects generator. This compressor behaves
like an automatic gain circuit, ensuring an optimum audio signal enters the internal
effects generator. If the EFX Send Clip LED blinks occasionally the maximum amount of
compression is being used. If the Clip LED remains illuminated for longer periods, turn down
the ‘EFX Send’ level until the LED blinks occasionally.
It is possible to use the internal digital effects and an external effects unit at the same
time. You can set one effects unit for reverb, and the other for a ‘special’ effect not
used often (like echo). Connect a cable from the EFX Send jack to the input of your
external effects unit, then connect a cable from the output of your external effects unit
into the Stereo Return jacks of the VGM14. You will then be able to use the Stereo
Return fader to control the level of the external effects.
5. Footswitch Jack
To switch the internal effects on and off, connect a standard footswitch to the Foot-
switch jack (e.g. Yorkville Apex model AFS-1). The EFX Mute LED illuminates when the
internal effects are muted (‘off’) by the Footswitch.
6. MON Fader
Audio signals from each channel Mon level control sum at the Mon fader. The Mon fader
adjusts the level of each channel’s signal into the monitor mix. From the Mon fader the
audio signal arrives at the Mon output phone jack, located on the top panel. The highlight-
ed section on the Mon fader’s graphics shows the fader’s usual operating position. If the
Mon fader’s knob is up at 10 dB, or down at -18 dB, check the position of the channel Gain
or Mon controls; be sure that they are not turned to either extreme of their setting range.
7. MAIN Fader
Audio signals from each channel Pan level control sum at the Main fader. The Main fader
adjusts the level of each channel’s signal in the main mix. From the Main fader, the audio
signal passes through the Main EQ to the Main Out phone jacks on the front panel and to
the Main Output XLR jacks on the rear panel. The highlighted area on the Main fader front
panel graphic shows the fader’s usual operating position. If the Main fader’s knob is up at
10 dB or down at -30 dB you may want to check the position of the channel Gain or Channel
Fader controls to be sure that they are not turned to the extreme of their setting range.
To ensure maximum signal head room and clarity, set the channel Gain and
Fader controls first for a good signal without clipping, then set the master for
the overall volume desired.
