Connections
Before connecting the S
PECTRALIZER
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 S
PECTRALIZER
operates with 24 bit word width. It accepts
16 bit and 20 bit inputs and will create output signals accor-
ding to the input resolution.
