Dangerous Music Monitor - Manual (Page 6)

Meter wiring
The “A-MTR” feed is a buffered output designed to drive the VU meters and
headphone amp in the MQ metering and cue box. The feed can also drive a standard VU
meter circuit. The Monitor’s D/A is calibrated so that a digital sine wave of 1 kHz
frequency at -14dBfs will provide a +4dBu signal level. Calibration tones are available
from the oscillator in the DAW or a test CD.
Standard VU meter circuit
The selected Digital Input to be monitored is fed to the “D-MTR” XLR on the rear panel.
This output is a standard AES digital output that goes to MQ’s AES input or another
digital meter or phase scope.
