Level Meter Accuracy O ver
Frequency
±0.1 dB from 20 Hz to 20 kHz with 0 to
–40 dBFS sine wave input, Peak Ballistic
mode. Within 5 Hz of some submultiples of
the sampling frequency it may be attenuated
additionally, as shown below. Sampling
frequency refers to the 192 kHz upsampled
data used for the bar ballistics For example:
1/12
th
of rate –0.30dB (16 kHz ± 5 Hz) 1/16
th
of rate –0.17dB (12 kHz ± 5 Hz) 1 /20
th
of
rate –0.11dB (9.6 kHz ± 5 Hz)
May not display full amplitude on fast
transients due to sampled nature of digital
signal
Audio Levels
Bars display signals up to 0 dBFS
Must not exceed maximum power
specification on analog outputs. Configure
output attenuation if necessary

The AES B connectors can be configured for input or output functionality.
Table 24: AES Audio Outputs (alternate function on second set of inputs)
Characteristic Performance requirement Reference information
Source AES Line B outputs can be sourced from
embedded, AES line A inputs (active
loopthrough) or analog inputs
If either Dolby option is installed, then the
source may also be a repeat of the encoded
Dolby stream, or decoded AES from a
Dolby input. See the Dolby spec section for
limitations
Number of Outputs
Up to 8 channels
Output Format AES 3-ID Output, 48 kHz, 20 bit for
embedded; 48 kHz, 24 bit for analog to AES.
For AES to AES loogthrough, output format
equals input format. Meets requirements of
SMPTE 276M-1995 (AES 3-ID)
For decoded Dolby Digital, output is 24 bits
at a rate of 32, 44.1, or 48KHz. For decoded
Dolby E the output is 24 bits at 48KHz, or
47.952KHz
Output Connector BNC, terminated, unbalanced
Output Impedance 75 Ω
Output Return Loss
Typically better than 30 dB to 24 Mhz
Tested in input mode
Output Amplitude Range 0.9 V to 1.1 V peak-to-peak into 75 Ω
