INTRODUCTION
Input/Output Configuration
OPTIMOD-DAB is designed to simultaneously accommodate:
•
Digital AES/EBU left/right inputs and outputs.
•
Analog left/right inputs and outputs.
Digital AES/EBU Left/Right Input/Output
The digital input and output follow the professional AES/EBU standard. They are both
equipped with sample rate converters to allow operation at 32, 44.1, and 48kHz sample
frequency.
To ensure best control of peak modulation, operate the output at 48kHz. This
guarantees that the output samples are synchronous with the peak-controlled
samples produced by the processing.
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. A second
digital input is available to genlock the 6200's output sample frequency to house sync, if
required.
OPTIMOD-DAB is designed to simultaneously accommodate digital and analog inputs
and outputs. You select whether OPTIMOD-DAB uses the digital or analog input on the
System Setup I/O Calib screen or by remote interface. Both analog and digital outputs
are active continuously.
Level control of the AES/EBU input is via software control through System Setup.
Analog Left/Right Input/Output
The left and right analog inputs are on XLR-type female connectors on the rear panel.
Input impedance is greater than 10kΩ; balanced and floating. Inputs can accommodate
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 30Ω; balanced and floating.
The outputs are intended for monitoring. Their output level is fixed at +14dBu full scale.
They can drive 600Ω or higher impedances.
Level control of the analog inputs is via software control through System Setup. (See
step 2 on page 2-24 and step 3 on page 2-26.)
