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
Input-to-Output Latency: two samples (e.g., 0.042
milliseconds @ 48 kHz sample rate)
Digital Audio Inputs: 5 (18 audio channels)
Configuration: two surround (5.1) and three stereo
Type: unbalanced AES3/SMPTE 276M (75 ohms/
1 Vpp)
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 Source: configured to follow L/R of currently
selected input or signal connected to sync input
Sync Input:
Compatible Sources: word clock, DARS (AES11),
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: 16 (eight pairs)
Configuration: organized as two surround (5.1)
and two stereo
Dynamic Range: >135 dB
Type: balanced AES3 (110 ohms/5 Vpp) or
unbalanced AES3/SMPTE 276M (75 ohms/1 Vpp),
selectable
Connector: 25-pin female D-subminiature (DB-25F)
Configurable Input Delay: 0 to 340 milliseconds @
48 kHz sample rate (scales up or down depending
on actual sample rate)
Post-Fader Monitor Output Level Offsets: each
surround and stereo channel independently adjust-
able in 0.5-dB steps over a ±12-dB range
Bass Management:
Supported Sample Rates: 44.1, 48, 88.2, and
96 kHz only
Crossover Frequency and Type: –6 dB @ 40, 50,
60, or 80 Hz, symmetrical for low-pass and high-
pass filters, maximally flat
Filter Slope: 12 or 24 dB/octave
Overall Operation: independent on/off selectable
for surround and stereo post-fader monitor outputs
Downmix:
Functions: surround to stereo, stereo to mono
Surround to Stereo:
L @ 0 or –3 dB;
R @ 0 or –3 dB;
C @ –3 or –6 dB summed with L and R;
LFE @ full attenuation or –6 dB summed with
L and R;
LS @ –3 or –6 dB summed with L;
RS @ –3 or –6 dB summed with R;
C, SUB, LS, and RS monitor outputs mute
Stereo to Mono:
L @ –3 dB summed with R @ –3 dB to C;
L, R, LS, RS, and SUB monitor outputs mute
For a surround input this results in the C output be-
ing the sum of L @ –3 or –6 dB, R @ –3 or –6 dB;
C @ –3 or –6 dB, LFE @ full attenuation or –6 dB;
LS @ –6 or –9 dB, and RS @ –6 or –9 dB.
Control Console Interface:

Connector: 9-pin female D-subminiature (DE-9F)
Remote Control Inputs: 2
Functions: remote mute all, remote dim
Type: 5 Vdc logic, activates on closure to system
common
Connector: 9-pin female D-subminiature (DE-9F)
AC Mains:
Requirement: 100 to 230 V, +10/–15%, 50/60 Hz,
15 W maximum
Connector: 3-blade, IEC 320 C14-compatible
(mates with IEC 320 C13)
