Introduction
The 4407 is a eight output AES3 digital audio synchroniser/converter. It is designed
to synchronise non-synchronous digital audio when locked to a AES11 reference. It
will also sample rate convert from any valid digital audio signal in the range 32kHz
to 54kHz to one of the available output sample clock rates; 32kHz, 44.1kHzand
48kHz.
The module features an on-board gain control, remote fader option and a
programmable automatic fade facility is provided.Audio modify features include
channel swap, either channel to both output channels and digital silence.
Remote control of gain and fader response is available through a dedicated RS484
serial port.
The module may be used in the 1050 3U and 10511U ICON modular product
rackframes with a choice of balanced or unbalanced rear connectors.
Characteristics of the 4407 are:
· eight outputs
· AES3 or SPDIF inputs
· sample rate synchronising for asynchronous 32kHz, 44.1kHz or 48kHz sources
when module locked to AES11.
· sample rate conversion from 32 to 54kHz
· AES11 reference input
· gain control 0dB to -12dB
· jumper selectable audio modify facilities (A-both,B-both, A/B swap and digital
silence)
· RS485 serial control (four wire and two wire) of gain and fader response
· automatic fade to or from silence in 0,1,2,4 or 8 seconds under serial control
· compatible with Pro-Bel COSMOS status monitoring.
