Specifications
Model 76D Central Controller
General Audio:
Supported Sample Rates: 32, 44.1, 48, 88.2, 96,
176.4, and 192 kHz
Word Length: 24 bits maximum
Internal Processing: 32 bits
Dynamic Range: 134 dB
Input-to-Output Latency: one sample (e.g., 0.021
milliseconds @ 48 kHz sample rate)
Digital Audio Inputs: five (18 audio channels)
Configuration: two surround (5.1) and three stereo
(2-channel)
Type: AES3id-2001/SMPTE 276M (75 ohms,
unbalanced)
Connectors: BNC (per IEC 60169-8 Amendment 2)
Sample Rate Conversion (SRC):
Application: available on Stereo Input C
Input Sample Rate Range: 8 to 216 kHz, limited to
1/6 to 6 times the output sample rate
Latency: 1 millisecond, nominal
Sync Input:
Sources: word clock, DARS (AES11), AES3id,
bi-level video, tri-level video
Jitter: 4 ns pp maximum
Connector: BNC (per IEC 60169-8 Amendment 2)
Termination: 75 ohms, selectable on/off
Digital Monitor Outputs: four (16 audio channels)
Configuration: organized as two surround (5.1)
and two stereo
Type: AES3 (110 ohms/5 Vpp) or AES3id/SMPTE
276M (75 ohms, 1 Vpp), selectable
Connector: 25-pin D-subminiature female
Configurable Delay: 0 to 340 milliseconds @
48 kHz sample rate (scaled up or down depending
on actual sample rate)
Downmix:
Functions: 5.1 to stereo, stereo to mono
5.1 to Stereo: LS @ –3 dB summed with L; RS @
–3 dB summed with R; C @ –6 dB summed with
L and R; LFE @ –6 dB summed with L and R (if
enabled); C, LFE, LS, and RS monitor outputs mute
Stereo to Mono: L @ –3 dB summed with R @
–3 dB to C; L, R, LS, RS, and LFE monitor outputs
mute. (For a surround input this results in the C
output being the sum of L @ –3 dB, R @ –3 dB,
C @ –3 dB, LFE @ –3 dB (if enabled), LS @ –6 dB,
and RS @ –6 dB.)
