Tone Controls; Effects Loop; Power Switch - YORKVILLE 100K Owner's Manual

Channel 3
This channel is also optimized for line level signals. The phone jack input is balanced
(TRS or Tip/Ring/Sleeve, +/-/gnd), however, it can also accept regular unbalanced cables.
Adjust the volume on the Channel 3 control for the level of sound desired.

TONE CONTROLS

The LOW and HIGH controls allow a wide range of tonal adjustment. The tone controls
affect the sound output from both channels. Increase or decrease the LOW control to
affect low frequency information and the HIGH control for high frequency information.

EFFECTS LOOP

The EFFECTS LOOP can be used to insert signals from external sources such as a Digital
Effects or Equalizers into the signal path. The loop is inserted after the tone and volume
controls. To use the EFFECTS LOOP connect the EFX SEND jack to the input of the
equalizer or effects unit. Connect the output of the equalizer or effects unit to the EFX
RTN jack to complete the loop.
LINKING TOGETHER MULTIPLE COMBOS
The EFX SEND jack can also be used as a LINE OUT source. The output is balanced
although an unbalanced cable can be used. The EFX RTN jack can also be used as an
AMP IN connection.
REVERB
The built in reverb adds reverberation to all three channels. The REVERB control sets the
level of reverberation added to the signal. To turn off the internal reverb, turn the reverb
control to zero. The effects loop is independent of the reverb circuit, so using the effects
loop does not affect the internal reverb.
PHONES
Headphones can be connected to the Yorkville 100kb by inserting a headphone plug
into the PHONES jack located on the front panel. While headphones are connected, the
internal speaker is disconnected. Always use stereo headphones. The audio heard
through stereo headphones will be a mono signal separated into the two earpieces.

POWER SWITCH

When the Yorkville 100kb Power Combo is turned on, the LED beside the power
switch will be illuminated.
