Instrument Input

This unbalanced high-impedance input connection is used to insert an instrument signal direct- ly into the preamp. Use the LINE switch to make instrument input or the rear panel line input active. Plugging into the instrument jack will override the rear panel 1/4” input jack (line input must be selected).

Line Select Switch

This switch, when lit, selects the rear line input or front panel instrument input (when some- thing is connected) as the source signal of the 376.

Drive Control

This control sets the amount of gain at the input of the vacuum tube stage. The range of gain available is +30 to +60 dB (-15 to +15 dB when LINE INPUT is selected).

Drive meter

This 4-segment LED meter indicates the input drive signal.

+48 Volt Switch

This switch activates phantom power for condenser microphones on pins 2 and 3 of the XLR mic input. You should connect your microphone before turning on the phantom power to pre- vent damage to your microphone. Be sure to always lower levels prior to using the +48 Volt Switch.

20db Pad Switch

This switch attenuates the microphone input signal by 20dB.

Phase Switch

This switch inverts the phase of the incoming signal at the Mic input by swapping pins 2 and 3 on the XLR connector.

Note- The +48 Vo lt , 20dB Pad and Phase functions are only available when the microphone input is in use.

Low Cut Switch

This switch places a 12 dB per octave shelving high pass filter in the signal path. The knee frequency of the Low Cut filter is 75 Hz. This filter is very useful for removing low frequency rumble or handling noise from a microphone input signal.
