4.10 Output Meters

A pair of peak

reading 10 segment LED

meters are used to indicate

output level. Green LED's

are used below 0 VU, yel-

low above 0 VU and red

LED's indicate clipping. 0

VU is equivalent to +4 dBu

(1.228Vrms). This meter

pair is switchable (with the

headphone output) to either

the Main Left and Right

outputs or the Aux 1 and 2

outputs. The red clip LED's

will illuminate if the sum-

ming amplifiers are clip-

ping even if the main output

controls are off, in which

case one or more inputs

must be turned down. Note:

The output meters are accu-

rately calibrated to the

transformerless output lev-

els, but not necessarily the

transformer-balanced out-

puts. See note on Trans-

former Balanced Outputs.

4.11 Main Output Level

These controls de-

termine the level of both

transformer balanced and

transformerless output stages for the Main Left and Right

outputs.

4.12 Main Output Mutes

These switches turn off both the transformer-bal-

anced outputs as well as the transformerless 1/4" stereo

outputs, and indicate the mute mode by lighting the red

LED near the switch. The headphone and metering func-

tions continue uninterrupted even though there is no sig-

nal on the mixer's main outputs.

4.13 Phantom Power Switch

This front panel switch enables the 48 Volt phan-

tom power supply for condenser microphones which can

use this feature. One switch controls all the inputs. If you

have a mix of condenser and dynamic microphones, the

phantom power will not affect the operation of the dy-

namic mics.

4.14 Mono Output Level

This control adjusts the level of the summed mono

output. It is completely independent of the Main Left and

Right masters.

4.15 Headphones Level

This control adjusts the level of the designated

output signal (Mains or Aux) to the headphone jack.

4.16 Meter/Phones Select

This switch selects either the Main Left/Right

outputs or the Aux 1/Aux 2 outputs to the LED meters and

the headphone jack.

4.17 Headphone Output

This front panel 1/4" TRS connector feeds a stan-

dard set of stereo headphones. A selector switch that also

controls the level meter allows monitoring the main or Aux

outputs.
