INTRODUCTION ORBAN MODEL 8382

Digital AES3 left/right inputs and outputs.

Analog left/right inputs and outputs.
OPTIMOD-TV can be operated in either stereo or dual-mono mode. In dual-mono
mode, processing parameters that determine the “sound” of the processor are the
same on both channels.
Dual-mono or stereo mode is a global system parameter. You can change modes
manually, via the 8382’s GPI inputs, via 8382 PC Remote software, or via the 8382’s
built-in time-of-day automation. Further, the 8382 can be programmed to recognize
the “stereo” and “dual-mono” flags in the AES input bitstream and to switch modes
accordingly. It will also set these flags appropriately in its output AES bitstream.
Digital AES3 Left/right Input/output
The digital input and output conform to the professional AES3 standard. They both
have sample rate converters to allow operation at 32, 44.1, 48, 88.2, and 96 kHz
sample frequency.
The left/right digital input is on one XLR-type female connector on the rear panel;
the left/right digital output is on one XLR-type male connector on the rear panel.
OPTIMOD-TV provides digital and analog inputs and outputs. You select whether
OPTIMOD-TV uses the digital or analog input either locally or by remote interface. If
OPTIMOD-TV is set to accept a digital input and the feed fails, OPTIMOD-TV will
automatically switch back to the analog input.
In dual-mono programming, the two programs must be combined into one AES3
stream to be accepted by the 8382. Similarly, the 8382 emits the two processed sig-
nals as one AES3 stream.
Level control of the AES3 input is accomplished via software control through System
Setup (see step 5 on page 2-23) or through PC Remote.
Both analog and digital outputs are active continuously.
The 8382’s output sample rate can be locked either to the 8382’s internal crystal
clock or to the sample rate present at its AES3 input.
The 8382 can apply J.17 de-emphasis to signals applied to its digital input and J.17
pre-emphasis to the processed signal emitted from its digital output. J.17 is a 6
dB/octave shelving pre-emphasis / de-emphasis standard with break points at 400 Hz
and 4 kHz. It is mainly used in older studio / transmitter links that use NICAM tech-
nology. The 8382’s provisions for J.17 make it fully compatible with systems using
this standard.
