Data Sheet

Dante Surround Input
The Model 792 provides a 16-channel “wide” Dante input for direct interfacing with applications that utilize Dante technology. As
with the Analog Surround Input, the format of the 16 input channels is not defined. Signals with a bit depth of up to 24 and sample
rate of 44.1, 48, or 96 kHz are compatible. The Dante surround input channels have a nominal signal level of –20 dBFS.
Analog Stereo Input
A 3-conductor 3.5 mm jack is located on the Model 792’s front panel and allows direct interconnection with the output of a
personal audio device. The input circuitry is optimized for use with “semi-pro” equipment that has a nominal level of –10 dBu.
A rotary level control and two signal-present LEDs enable a user to easily optimize the sensitivity of the input circuitry, match-
ing its performance to the nominal level of the connected source. A high-performance ADC circuit converts the analog signal
to 24-bit digital.
Dante Stereo Input
The Model 792 provides two Dante digital audio input channels for interfacing with a stereo source. As with the Dante Surround
Input, the Dante Stereo Input has a nominal level of –20 dBFS, a bit depth of up to 24, and sample rate support of 44.1, 48, and
96 kHz.
Three Monitor Outputs
The StudioComm with Dante Support system provides three monitor outputs: one 16-channel Dante digital, one 16-channel ana-
log, and one 2-channel stereo Dante digital. Configuration choices allow the characteristics of the three outputs to be optimized
to meet the requirements of specific applications. For flexibility, a configuration menu choice allows the level of each analog
output channel to be individually adjusted (“trimmed”) over a range of ±20 dB in 0.1 dB steps.
Analog Output
The Analog Surround Output is 16 channels “wide” and can be selected for pre- or post-fader (before or after the level control)
operation. These analog output channels are intended for connection to inputs on audio amplifiers or powered loudspeakers
associated with a monitor loudspeaker system. Power-up/power-down muting relays help to protect the loudspeaker system
from unwanted transient signals.
The analog surround output channels have a nominal level of +4 dBu and are electronically balanced, capacitor-coupled, and
ESD (static) protected. High-quality components, including the critical digital-to-analog converters, are used to provide low-
distortion, low-noise, and sonically excellent performance. Robust circuitry provides protection from damage should a moderate
DC voltage be accidentally connected, something especially useful in broadcast applications. The analog outputs are compatible
with virtually all balanced and unbalanced loads with an impedance of 2 k ohms or greater.
The Model 792’s analog output channels have a maximum level of +24 dBu. This allows both compatibility and significant
headroom in applications where digital audio input signals with a nominal level of –20 dBFS need to be converted into analog
signals that have a nominal level of +4 dBu.
Dante Surround and Stereo Outputs
The Model 792 provides two Dante monitor outputs. One is 16 channels and the other is 2-channel stereo. Each is selectable to
be either pre- or post-fader and can be routed (Dante subscribed) to inputs on compatible monitor loudspeakers. They can also
be utilized for level metering or other general-purpose uses, typically configured for pre-fader operation. The nominal level of
the Dante monitor outputs is –20 dBFS. Each Dante output channel can have its level individually adjusted (“trimmed”) over a
range of ±20 dB with a step size of 0.1 dB.
Dante Performance
Two of the Model 792’s three gigabit Ethernet ports are utilized by the Dante audio interfaces. These ports can be selected, using
the Dante Controller software application, for switched or redundant Dante operation. Support is provided for both AES67 and
Dante Domain Manager™ (DDM) operation. The Model 792 will also support Dante’s ST 2110 implementation.
The StudioComm with Dante Support system allows the Dante audio sample rate to be selected for 44.1, 48, or 96 kHz with
a bit depth of 24. The Dante Controller software application is used to route (subscribe) the Model 792’s receiver (input) and
transmitter (output) channels with the associated Dante compliant-equipment.
