Rear Panel - Traynor Custom Special 50 Mode D'emploi

Channel 2 Tone Controls
15
The Treble, Middle and Bass tone controls help you shape your sound. They are pre-gain
/ pre-volume in the U.S.A. mode and post-gain / pre-volume in Brit mode. These are active
only when Channel 2 is selected.
Reverb Control
17
The Reverb Return controls the amount of reverb return from the internal Accutronics®
spring reverb tank. This control is active only when Channel 2 is active.
Effects Control
18
This controls the amount of return signal from the external effect plugged into the rear panel
EFX RTN jack. This control is active only when Channel 2 is active.
Master Controls
Presence, Resonance Controls and the Voice Switch
The Presence Control shapes the overall brightness of both channels. The Resonance
Control adjusts the damping factor of the speakers in the bass frequencies, helping loosen or
tighten the bottom end. Turning the Resonance control up (clockwise) will add more rumble,
turning it down (counter-clockwise) tightens up the bottom end.
The voice switch bypasses the Resonance and Presence controls. The amplifier is now
operating in an "open loop" mode which permits full tube tone without alteration.
Master Volume
22
The Master volume controls the overall level of both channels.
Standby Switch and Indicator
This switch controls the high voltage power being supplied to the output 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 output tubes.
Note: The preamp will remain active when in Standby mode allowing the use of the D.I. Output
for direct recording without sound coming from the speakers.

Amp Mode
25
The YCS amplifiers can be operated in two different modes, full-power class AB and low-
power class A. When operating in full-power mode, the full voltage is applied to the output and
preamp tubes and the amplifier operates in a traditional class AB configuration. Selecting the
low-power mode cuts the operating voltage by half and increases the bias in the output tubes
to full class A operation. This allows the output and preamp to operate with a great deal of
more 'saturation.' Operating in Low Power mode also results in extended tube life.
XLR Balanced D.I. Line Out Jack
For maximum versatility, The YCS amplifiers have an XLR D.I. Line Out. The signal sent from
this output is post-master and has the Traynor Dyna-Sound speaker simulator compensation.
This speaker output does not remain active when the amplifier is in standby mode so the
YCS amplifier can be used as a preamp for recording.
Note: The XLR Balanced line output signal is affected by all tone controls, including reverb
(but not the Master Volume).
