Output Level Control
The OUTPUT LEVEL control provides gain or attenuation to adjust for a variety of system operating levels.
This control affects the levels sent to the A/D converter and to the balanced analog OUTPUT jacks.
Output Level Meters
The ART Voice Channel™ provides both analog and digital output meters. The meters monitor the signal
level just after the output control. This signal is sent to both the analog and digital outputs.
“0” VU on the analog VU meter corresponds to +4dBu on the balanced outputs, and about –20dB on the LED
bargraph meter.
The LED bargraph meter indicates peak levels as well as average levels. Average levels are indicated by a
continuous string of LEDs being lit. Peak levels are indicated by a single LED and are held for about 2
seconds. The last LED in the meter is marked “Clip”, and it indicates that the output level is set too high.
The A/D Clip indicator LEDs act independent of the OUTPUT LEVEL meter. This provides an accurate
indication of A/D converter clipping. This is useful when using the A/D insertion jacks, since the level at the
converters will not be indicated on the main meters when these inputs are used.
