Yorkville Sound YS1003 owner manual Channel 1 5, Channel 2 8 9, Master Controls

Channel 1 5 7

Channel 1 is the lead/overdrive channel and is selected in one of two ways, via the Channel Select switch on the control panel, or via the Channel Select button on the supplied footswitch* pedal. A Yellow LED located next to the Channel 1 Volume control illuminates when Channel 1 is active.

*Note: Plugging in the footswitch deactivates the panel- mounted Channel and Boost controls.

Gain & Volume Controls 2

Channel 1 uses a Gain control in conjunction with a Volume control to control the amount of tube-based overdrive and volume. The Gain control is used to adjust the amount of overdrive, while the Volume control allows you to set the actual loudness of the amplifier.

Boost Switch 3 4

A boost circuit is included to help you achieve ‘a-bit- more’ overdrive for leads. The boost can be selected via the front panel switch or through the supplied footswitch pedal. A Red LED illuminates to indicate when the boost is active.

Channel 1 Tone Controls 6

The Treble, Bass, and Middle tone controls are used to help you shape your sound. They are post-gain and pre-volume. These are active only when Channel 1 is selected.

Channel 2 8 9 11

Channel 2 is the clean channel and thus has no Gain control. In other respects the layout is the same as that of Channel 1, with independent Volume and Treble, Bass, and Middle tone controls. When channel 2 is active the green LED located next to the Channel 2 Volume control is illuminated.

Brightness Switch 10

Channel 2 includes a Brightness switch that activates a circuit to provide additional treble boost to help make your tone sparkle.

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

along-style Accutronics® dual-spring reverb for authentic vintage reverb.

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 (preamp-out). The - 10dBu output is ideal for most guitar effects pedals and professional signal processors. You can also use this output to slave the YCV50 with another guitar amplifier by plugging into the Rtn jack of the slave amplifier.

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 dual-latching switches, each with a separate LED indicator.

The switching is accomplished with internal relays so there is no audiable noise flowing through the footswitch cable. Footswitch-induced noise is never an issue. The YCV50 is compatible with most aftermarket latching dual-footswitch pedals.

External Speaker Jack/s 20

These under-the-chassismounted 1/4 inch jacks allow convenient connection of an 8-ohm external speaker cabinet. If you disconnect the internal 12 inch Celestion® speaker, you can connect up to two 8-ohm external cabinets.
