Yorkville Sound All-Tube Guitar Amplifier YS1036 - Manuel (Page 6)


Channel 1
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 1
Select button on the supplied footswitch pedal. The
red LED, located next to the Channel 1 Select Switch
illuminates when Channel 1 is active.
Gain & Volume Controls
4
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 volume of the channel.
Boost Switch 5
A boost circuit is provided to help achieve more
overdrive for leads. The boost can be selected via the
front panel switch. A red LED illuminates to indicate
when the boost is active.
Channel 1 Tone Controls
7
The Treble, Bass, and Middle tone controls help shape
your sound. These controls are post-gain and pre-
volume and are active only when Channel 1 is selected.
Modern Switch
8
The Modern switch controls the frequency range that
the tone controls work in. You can choose from a more
vintage sound with emphasis on the midrange or a
slightly deeper modern sound. The green LED above
the switch indicates that you are in modern mode.
Scoop Switch
9
The Scoop provides deep midrange cut with a bass
boost to get that deep, chunky sound. A yellow LED
indicates when you are in the Scoop mode.
Reverb Return
11
The Reverb Return controls the amount of reverb return
from the internal Accutronics® spring reverb tank. This
control is active only when Channel 1 is active.
Effects Return 12
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 1 is active.
Channel 2
All of the functions of Channel 2 are
identical to Channel 1 with the exception
that there is slightly more bass dialed in
so that Channel 2 will sound a bit fatter
at lower gain settings, making it better
suited for crunch sounds.
Channel 3
Channel 3 is the clean channel; it has one less gain
stage available. All of the functions remain the same
as Channels 1 and 2 with the exception that the Scoop
function has been replaced with a Bright switch to add
more sparkle to your clean sound. By incorporating the
Boost switch, Channel 3 can also give you a variety of
overdrive sounds as well.
Master Controls
Presence Control
13
The Presence Control shapes the overall brightness of
all three channels.
Resonance Control
14
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) adds more rumble, turning it
down (counter-clockwise) tightens up the bottom end.
Solo Control
15
The Solo Control adjusts the amount of extra volume you
can kick in via the footswitch or the panel mounted control.
Master Volume
16
The Master Volume control adjusts the overall level of
all three channels.
Tuner Mute
17
The Tuner Mute switch cuts the amplifier, D.I. and
headphone outputs. The Tuner Out jack will remain
active for silent tuning of your guitar.
Standby Switch & Indicator
18 19
The Standby switch controls the high-voltage power being
supplied to the output tubes only. Standby mode 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 (when in Standby
mode). 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.
The pre-amp tubes remain active so that the D.I. and
headphone outputs can be used for silent practice or for
recording. You do not need to connect speakers to
the amplifier when operating in standby mode.
EFX Send Jack, Return Jack & Send Level 23
24

Send jack of the YCS100 and then connect
