Master Controls
Master Volume Control 12
The Master Volume control adjusts the overall volume of the amplifier.
Reverb Control 13
The Master Control section also includes a rotary Reverb control that adjusts the overall reverb level for both channels. The YCV50 is equipped with
a
Standby Switch & Indicator 14 15
This switch controls the high voltage power being supplied to the tubes. This mode effectively keeps the tubes warmed up when the amp is not in use. The large, jewel indicator on the front panel glows Red when the amp is fully powered- up and changes to Yellow when the high voltage circuit has been turned off. Putting the amp into Standby mode (i.e. during set breaks) shuts off the amplifier output stage and effectively increases tube life by reducing wear on the tubes.
EFX / LINE Send & Return Jacks 18
The Send and Rtn jacks of the YCV50 allow convenient use of an external effect unit. Simply connect a 1/4 inch phone cable to the Send jack of the YCV50 and then connect this cable to the Input of your effects unit. To send the processed signal back to the YCV50, connect the output of the effects unit to the Rtn jack of the YCV50.
The 1/4 inch TRS Send jack can be used as part of an effects loop in conjunction with the Rtn jack. It can also be used as a direct line out
The 1/4 inch TRS Rtn jack can be used as your return jack for your effects loop. It accepts an input signal that is passed to the power amplifier, so it can be used as a power amp in. The Master Control section regulates the signal, so you can add Reverb as well as Presence.
Footswitch Jack 19
Connecting a footswitch to the 1/4 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
The switching is accomplished with internal relays so there is no audiable noise flowing through the footswitch cable.
