with Dante Support
Support for two 2-channel stereo inputs is
also provided. A Dante stereo input allows
two channels of Dante audio to be selected
for monitoring. An unbalanced analog in-
put, located on the Model 792’s front panel,
allows the output of a “semi-pro” personal
audio device to be directly connected.
The audio performance of the Model 792’s
analog inputs is very good. Low-noise, wide
dynamic-range circuitry ensures that the
audio quality is preserved. The analog audio
signals are routed to high-performance ana-
log-to-digital conversion (ADC) circuitry that
supports a bit depth of 24 and sample rates
of 44.1, 48, and 96 kHz. A precision volt-
age-reference circuit helps the ADC circuitry
perform highly accurate signal conversion.
The audio signals, now in the digital domain,
are routed to a high-speed programmable
logic (FPGA) device where they are mixed
and level-controlled as necessary.
Each of the four inputs, two surround and
two stereo, can have a unique name as-
signed to it. This can be helpful when a
Model 793 Control Console user is selecting
which input to monitor. In addition, a time
delay can be applied to each input, useful
for compensating for video processing or
display “latency.” Delays of up to 999 milli-
seconds, as related to a sample rate of
48 kHz, can be applied. Each input channel,
36 in total, can be level “trimmed” over a
±20 dB range in steps of 0.1 dB.
Analog Surround Input
The Model 792 provides 16 independent
analog input channels which are compat-
ible with balanced or unbalanced line-level
sources. These inputs have a nominal level
of +4 dBu and are electronically balanced
(dierential), capacitor-coupled, and ESD
(static) protected for reliable operation in
demanding applications. Extensive ltering
minimizes the chance that radio frequency
(RF) energy will cause interference. The
analog inputs are protected from damage
should a moderate DC voltage be acciden-
tally connected. These characteristics make
the analog inputs suitable for use in studio
and mobile facility environments. The analog
input signals are converted to 24-bit digital
and then utilized by the internal logic circuit-
ry. Compatible signal sources include audio
consoles, broadcast playback equipment,
and analog output ports on routers and
networked audio equipment.
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 for-
mat of the 16 input channels is not dened.
Signals with a bit depth of up to 24 and
sample rate of 44.1, 48, or 96 kHz are com-
patible. 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, matching 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
