Studio Technologies Model 76D Central Controller

As creating and distributing multi-channel surround (5.1) and stereo audio material has become a day-to-day reality, the ability to simply and effectively monitor these sources is imperative for recording, post- production, and broadcast facilities. And with audio-with-picture applications becoming so prevalent, additional monitoring challenges have arisen. Studio Technologies has addressed these needs with the StudioComm for Surround Model 76D Central Controller and the Model 77 and Model 71 Control Consoles. With digital audio inputs, digital monitor outputs, support for multiple user control surfaces, and an extensive set of operating resources it's a simple task to integrate a monitoring system into virtually any facility. The carefully selected group of features, including surround and stereo inputs, configurable input-signal time delay, multiple pre- and post-fader outputs, configurable downmix and mute/solo functions, and bass management, along with a multi-format sync input, make the system powerful yet simple to operate. And by using the best of contemporary technology, as well as following rigorous design practices, the system's audio quality is excellent.

New Features: 

A new software release adds enhanced capabilities to the StudioComm 76D/77 system. To support a broader range of loudspeaker systems an advanced set of bass management resources has been added. The bass management function redirects low-frequency energy from the main channels, combines it with the LFE content, then routes the sum to the subwoofer output. The downmix capability of the 76D/77 has also been enhanced with the addition of configurable level coefficients.

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: AES3 unbalanced (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: AES3 balanced (110 ohms/5 Vpp) or unbalanced (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 adjustable 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 being 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
