Power Switch – Switches both channels of the amplier ON or OFF. The
power light will glow when power is ON.
Unbalanced (¼") Input (×2) – Unbalanced input of the amplier (one per
channel). The ¼” input overrides the balanced XLR input if both are
connected.
Standby Switches (×2) – These control high voltages to the tubes,
independently for each channel. Allow 60 seconds aer powering up before
seng standby to the ON posion.
Warning! If you are only using one channel make sure that the other
channel is set to STANDBY, regardless of whether or not input signal is
present in the unused channel.
Level Control (×2) – These knobs set the output volume for each of the
amplier’s 2 channels.
Presence Control (×2) The acve presence circuit alters the high
frequency component of a signal, adding “brightness” or “sparkle” while
retaining a pleasant high-end quality. The presence circuit is completely
disengaged for true at response with the knob fully counterclockwise.
Channel Fuse – These dual compartments house the 250A Fast blow
type fuses which protect the le and right channels.
Bias Controls – Each channel is equipped with a front panel bias adjust
trim pot, plus its own test point. A common ground serves both channels.
