EFX Send, Return Jacks and Controls
The Send and Return jacks of the YCS amplifiers allow convenient use of an external effect
unit. Simply connect a ¼-inch cable to the Send jack and then connect this cable to the input
of your effects unit. To send the processed signal back to the YCS amplifier, connect the
output of the effects unit to the Rtn jack on the YCS amplifier. The Efx Send Level control
(located next to the Efx Send and Return jacks) enable fine adjustments to the signal being
sent to, and returning from external effects units.
The ¼-inch TRS Send jack is used as part of an effects loop, in conjunction with the
Rtn jack. The -10dBu output is ideal for most guitar effects pedals and professional signal
processors. You can also use this output to slave the YCS amplifier with another guitar amplifier
by plugging into the return jack of the destination amplifier which will be the slave amplifier.
The ¼-inch TRS Return jack is used as your return jack for your effects loop. The individual
Effects Rtn controls are used to control the amount of effect returning to the amplifier.
Note: The Effects Send and Return have been designed with a parallel effects loop. This
design allows the true signal (bypassed) to be blended with the external effect using the
Effects blend control. The parallel loop also features balanced jacks which enables better
integration with rackmount effects processors.
Amp In and Preamp Out Jacks
The Amp In and Pre-Amp Out jacks can be used as a loop-thru for guitar pedals or other
effect devices. Simply plug a ¼-inch cable from the Pre-Amp Out jack of the YCS amplifier
into the input of the effect unit or pedal. Plug another ¼-inch cable from the output of the
effect unit, or pedal, to the Amp In jack of the YCS amplifier. This is handy when you have
devices that are intended to be inserted into the signal chain.
Tech Note: The signal level at this point is -10dBV so it will work with most guitar effect pedals
as well as professional rack equipment.
Footswitch Jacks
30
Connecting a footswitch to the ¼-inch TRS Footswitch jack deactivates the control panel mounted
Channel Select and Boost switches. These functions are then activated exclusively by the pedal.
The included footswitch features dual-latching switches, each with a separate LED indicator.
There is also a ¼-inch footswitch jack enabling the reverb and effects returns to be defeated.
The switching is accomplished with internal relays so there is no audio flowing through
the footswitch cable. Footswitch-induced noise is never an issue. The YCS50,YCS50H and
YCS90 are compatible with most aftermarket latching dual-footswitch pedals.
External Speaker Jack/s and Impedance Selector Switch
The dual ¼-inch jacks allow convenient connection of external speaker cabinets. By
disconnecting the internal 12-inch Celestion® speaker(s), up to two 8-ohm external
cabinets can be used.
Note: Insure that speakers are properly connected and that the impedance selector is set to
the appropriate position before operating the amplifier.
Speaker Cabinets
You can either connect speakers in parallel or series. Most speaker enclosures have
parallel output jacks that enable users to chain speaker extension cabinets together. Series
connections are rarely used.
The easiest way to describe this is if you have two 8-ohms speaker cabinets connected in
parallel the resulting impedance would be 4-ohms (16-ohms if they were wired in series).
