much of the wet (effected signal) is blended with the dry signal (un-effected signal). This can range
from totally dry (without effects) to mostly wet (effects applied).
Tip: If a wetter signal is desired, set the output signal from the external effects processor to a high output.
Bass Resonance control
The Bass Resonance control adjusts the amount of low frequency damping of the amplifier. Turning
the control clockwise towards loose reduces the damping factor and allows the resonance of the
speaker cabinet to be more pronounced. Setting the control towards tight increases the damping fac-
tor to help achieve a punchier sound.
Selectable Limiter
In order to prevent hard clipping of the power amplifier, a selectable limiter is provided.

Master Volume Control

The Master volume control allows adjustment to the overall signal level of the amplifier.
Blue-VU Meter
The 12 LED VU-meter monitors the overall signal going into the power amplifier. The amber LED indi-
cates that the signal is approaching maximum input to the power amplifier and a red LED indicates
the signal has exceeded its maximum (and clipping may occur). A peak-hold function allows the
highest signal LED, tracked by the VU meter, to remain momentarily lit allowing users to monitor the
output while playing.
Protect LED
The red Protect LED displays the status of the internal protection circuitry. When the XS800HH is ini-
tially powered up internal protection circuits are activated, no output will be heard until the red Protect
LED automatically shuts off. In a rare case of amplifier shutdown or if the output is shorted, the ampli-
fier will take approximately 15-20 seconds to re-initialize and obtain full power.

Mute Switch

The Mute switch disengages the preamp signal from the Line Out and power amplifier, disabling sig-
nals sent to the mixing console and speaker cabinets. The Tuner Out jack is still enabled (see Tuner
Out in the Rear Panel section).

Rear Panel

Dual Footswitch Jack (Tube-Drive and EFX-Return)
A dual footswitch jack can be used to switch the
The footswitch uses a standard TRS ¼-inch based dual footswitch (AFS-2). When either effect
is switched on, corresponding LED's on the amplifier and the foot switch will illuminate on and off
together. The Effects are only switchable by the footswitch, but the
abled by either the footswitch or the switch located on the front panel. The footswitch control will
override the front panel switch.
Tuner Out
The Tuner Out ¼-inch jack sends the signal from your bass guitar to an outboard instrument tuner.
Simply connect one end of a ¼-inch shielded cable to the Tuner Out jack and the other to the instru-
ment tuner. Pressing in the Mute button will mute the output to the speakers as well as to the line out.
Tip: Leave your tuner connected to the Tuner Out jack and Mute the signal any time you wish to tune
in silence. A very handy feature when onstage and the unpleasant sound of tuning is not something
you wish the audience to hear amplified through your performance speakers or the sound system.
