Connections

Rear view Loudness Maximizer, Model 9632

Before connecting the Loudness Maximizer switch the power off at all connected units.

The rear panel provides AES/EBU- and S/P-DIF-inputs and outputs. Any additional channel, status and user-bits are passed through unaltered, and the outputs can be used at the same time if required.

The Loudness Maximizer operates with 24 bit word width. It accepts 16 bit and 20 bit inputs and will create output signals according to the input resolution.

For synchronisation purposes Wordclock In and Wordclock Through BNC connectors are fitted with a switchable 75 Ohm termination.

MIDI In and MIDI Through connectors allow presets to be selected via MIDI program change commands.

For easy upgrade of future software releases, the rear panel offers RS-232 interface for PC and RS-422 interface for MAC.
