INTRODUCTION

Analog Left/Right Input/Output

Remote Control Interface

You select whether OPTIMOD 6300 uses the digital or analog input either locally or
by remote interface. If OPTIMOD 6300 is set to accept a digital input and the feed
fails, OPTIMOD 6300 will automatically switch back to the analog input.
In dual-mono mode, the two programs must be combined into one AES3 stream to
be accepted by the 6300. However, you can configure the 6300 so that one digital
output is dedicated to channel 1 and one output to channel 2 in dual-mono mode.
You can also configure the outputs so that one or both outputs carry both channels.
Level control of the AES3 input is accomplished via software control through System
Setup (see step 7 on page 2-23) or through PC Remote.
Both analog and digital outputs are active continuously.
The 6300's output sample rate can be locked to the 6300's internal crystal clock, the
sample rate present at its AES3 input, the sample rate present at its AES11 sync in-
put, or wordclock.
The 6300 can apply J.17 deemphasis to signals applied to its digital input and J.17
preemphasis to the processed signal emitted from its digital output. J.17 is a
6 dB/octave shelving preemphasis/deemphasis standard with break points at 400 Hz
and 4 kHz. It is used mainly in older studio / transmitter links that use NICAM tech-
nology. The 6300's provisions for J.17 make it fully compatible with systems using
this standard.
The left and right analog inputs are on XLR-type female connectors on the rear
panel. Input impedance is greater than 10k; balanced and floating. Inputs can ac-
commodate up to +27dBu (0dBu = 0.775Vrms).
The left and right analog outputs are on XLR-type male connectors on the rear
panel. Output impedance is 50; balanced and floating. The outputs can drive 600
or higher impedances, balanced or unbalanced. The peak output level is adjustable
from –6dBu to +24dBu.
Level control of the analog inputs and outputs is accomplished via software control
through System Setup (see step 5 on page 2-21 and step 8 on page 2-23) or through
PC Remote.
The Remote Control Interface is a set of eight optically isolated GPI inputs on a DB-
25 connector, which can be activated by 5-12V DC. They can control various func-
tions of the 6300:

Recall any Factory Preset, User Preset, Test Mode state (Bypass or Tone), or exit
from a Test Mode to the previous processing preset.
