Channel Numbering Channel numbers per SMPTE 272M and
SMPTE 299M (1 through 16) will be correctly
shown on all displays.
Audio Levels Bars display signals up to 0 dBFS. Must not exceed maximum power

Characteristic Performance requirement Reference information
Number of Channels Provides up to two sets of six channels of
professional balanced differential inputs
for each video input, 12 channels total.
Input Connector
Balanced, unterminated through rear
panel connector.
Level Meter Accuracy over Frequency ± 0.5dB from 20 Hz to 20kHz 0 to
–40dBFS sine wave, Peak Ballistic mode.
Cross Talk (typical) ≤ –80 dB, typically ≤ –90 dB from 20 Hz to
20 kHz, inputs driven from <600 Ω source
impedance.
De fi ned as the displayed bar level in
any channel that results from a full scale
signal on a different input pair in that
input.
Maximum Input Levels +24 dBu
Must not exceed max power speci fi cation
on analog outputs. Con fi gure output
attenuation if necessary.
Sampling Resolution 24 bits at 48 kHz.
Input Impedance (typical) 24 k Ω , balanced. Unbalanced input impedance is typically
18 k
Ω .
Off Isolation (typical) ≤ –80 dB, from 20 Hz to 20 kHz. Unused
input terminated by <600 Ω source
impedance.

Audio Modes Balanced: Provide a full-scale output
of 24 dBu. This mode is intended for
professional balanced applications.
Unbalanced: Intended to drive the
unbalanced inputs of consumer ampli
fi ers,
in which case one side of the line must be
grounded.
Outputs are to drive line level inputs. Not
intended to drive speakers directly.
