equivalent)
Rating: 0.200A for 100 and 120V mains power,
0.100A for 220/240V mains power
Insert Switcher:
Applications: allows routing of three unbalanced
stereo analog audio signals into audio path
Switching: passive (no electronics in signal path)
Nominal Operating Level: not specified
Audio Inputs:
Qty: 4, stereo (separate left and right input
connectors)
Type: electronically balanced, direct coupled,
compatible with balanced or unbalanced signals
Impedance: 24k ohms
Nominal Input Level: –10dBv or +4dBu, each
input individually configurable
Common Mode Rejection: 100dB @ DC and
60Hz, 70dB @ 20kHz, 62dB @ 40kHz (typical)
Control Room Output:
Qty: 1, stereo (separate left and right output
connectors)
Type: electronically balanced, intended to
drive loads of 600 ohms or greater, balanced
or unbalanced
Output Level (input source at nominal level):
–68dBu at 0% rotation (fully counterclockwise),
–50dBu at 25% rotation, –32dBu at 50% rotation,
