(4) Level - This is the channel’s master volume control. It determines the amplitude of the signal sent
to the rear panel LINE OUTPUT ( #8 on page 16) and INSERT SEND ( #11 on page 16) jacks. This
control also sets the level sent to the A/D converter inputs.
(5) +48V - Most modern condenser microphones require +48 volts of phantom power to operate. When
in the up position, 48 volts of phantom power are available at the channel’s rear panel MIC INPUT.
(See page 21 for more information about phantom power)
(6) -15 dB PAD - When enabled (placed in the up position), the channel’s MIC INPUT signal will be
reduced by 15 dB (this switch has no effect on LINE INPUT or Hi-Z signal). Use the PAD to reduce the
incoming signal in cases where undesired distortion is present at low gain levels (for instance, where
especially sensitive microphones are used on loud instruments or if the A/D converter is clipping).
(7) Input Select - Determines whether the channel’s MIC (up position) or LINE (down position) input is
active. If the channel’s Hi-Z input is in use, this switch has no effect.
( See “Analog Connectors” on page 15 for more info on the rear panel inputs)
(8) Meter - This standard VU meter can display the channel’s overall output level, tube drive level, or
amount of compressor gain reduction. The function that is displayed depends upon the setting of the
Meter Function switch (#9 on page 11).
 Keep phantom power off (switch down) when it is not required.
 To avoid loud transients, always make sure phantom power is off when connecting or
disconnecting microphones.
 Always check the power requirements of your microphone with the manufacturer before
applying phantom power.
 The numeric values for the Gain and Level knobs are relative scale markings and do not
represent specific dB values.

You can come up with many useful tonal variations by experimenting with different Gain
and Level settings.
