Headphone Gain
Adjusts headphone output level. Turn down when not in use.
Headphone Jack
The headphones output is a high level stereo ¼” TRS Jack output, capable
of driving headphones impedances of 8 Ohms or above.
WARNING – High headphone levels may damage your hearing
The Headphones Gain control allows the headphone output level to be
adjusted.
The Mute ON and PA ON switches do not affect the headphones output.
This unit puts out up to half a watt per channel into 8 ohms – more than enough
for any player at home. We recommend using quality headphones such as Sony
model MDR 7505.
Tuner Out
Buffered output so it will not load down the pickup or the rest of the signal chain,
nor will it allow noise from the tuner to get back into the system. May be used
simultaneously with the Tuner Out jack on the rear panel. Output impedance is
approximately 500 ohms. These outputs are buffered for feeding to a guitar tuner.
The Mute ON switch does not affect these outputs; they are
always ON
.
Thermal

amplifier. The LEDs indicate a low (green), medium (yellow), or high (red)
temperature range. (For more details see the Thermal Management System
section)
The LEDs will also indicate a fan speed out of specification condition as
described later, in the
Thermal Management System; Fan Speed out of Spec
Indication paragraph
.
