OPTIMOD TECHNICAL DATA
6-3
Maximum Input Level: +27 dBu, peak.
Connector: Two XLR-type, female, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and
3 electronically balanced, floating and symmetrical.
AD Conversion: 24-bit 128X oversampled delta sigma A/D converter with linear phase
anti-aliasing filter.
RF Filtering: Effective 0.5-1000MHz.
High Pass Filter: 0.15 Hz.
Analog Audio Output (Monitor)
Note that this output is not intended to be used as a transmitter output, rather it is for
monitoring. Nevertheless it has been designed for low noise, distortion, and overshoot
and can drive an STL or transmitter in an analog plant. Peak control will not be as good
as at the digital output because on-air samples will be asynchronous with peak-
controlled internal samples.
The source of this output is switchable between the peak limiter output and the multi-
band compressor output. Because most of the delay occurs in the peak limiter, this can
make headphone monitoring much more comfortable for on-air talent.
Configuration: Stereo output.
Source Impedance: 30
Ω
, electronically balanced and floating.
Load Impedance: 600
Ω
or greater, balanced or unbalanced. Termination not required or
recommended.
Output Level Control: Fixed at +14 dBu peak, with MON OUT source set to “POST LIM-
iter.” Pre-limiter peaks up to +26 dBu possible. No output level adjustment control is
provided.
Signal-to-Noise: 90 dB unweighted signal-to-noise, 20Hz-20kHz (bypass mode).
Distortion:
<
0.01% THD (Bypass mode) 20Hz-20kHz.
Connector: XLR-type, male, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and 3 elec-
tronically balanced, floating and symmetrical.
DA Conversion: 20-bit 128X oversampled D/A converter.
DC Offset: Less than 10mV.
RF Filtering: Effective 0.5-1000MHz.
Digital Audio Input
Configuration: Stereo per AES/EBU-standard (AES3-1992), 20 bits resolution, software
selection of stereo, mono from left, mono from right or mono from sum (as source to use
as a mono processor). Labeled “AES/EBU Input.”
Sample rate: 32, 44.1 or 48kHz, automatically-selected.
Connector: XLR-type, female, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and 3
transformer balanced and floating, 110 ohm impedance.
Status Bits: Input channel status is ignored. Input User bits are optionally passed through
to the output.
Input Reference Level: Variable within the range of
−
10 to
−
30dBFS (VU) in 0.5dB steps.
RF Filtering: Effective 0.5-1000MHz.
