11.8 DIGITAL AUDIO INPUT
Transformer balanced XLR-type and optic connectors are used to input AES-3, S/PDIF,
IEC60958, EIAJCP1201 digital audio.
To avoid malfunctions, only one digital connector may be connected at a time. Please keep
the tos-link connector covered while not used.
The digital input accepts any sampling rate between 32 and 96 kHz. No user adjustment is
necessary since a sample rate converter is built into the unit. Furthermore, digital input
automatically recognizes the digital format
(AES, EBU, SPDIF, etc.) and the type of
connection (optic or coaxial).
Even though both analog and digital input audio cables can be connected, only one input
can be set active (analog/digital input selection is done through the software parameter
setting - par. 12.1). Input gain and level setting for digital input is fixed.
XLR pinout: Pin 1 Gnd
Pin 2 Signal
Pin 3 Return
In case of unbalanced connections (as required by S/PDIF format), shortcut pin 3 and 1 or
connect the unbalanced signal to XLR Pin 2 (hot) and Pin 3 (Gnd).
11.9 SERIAL PORTS
Falcon 15 features two optoinsulated RS232 serial ports which allow the remote control
and RDS programming via a connected PC (ref to Chapter 16).
Connect a standard serial cable (not crossed) between the RS-232 connector and a serial
port connector on the computer. Cable length must not exceed 10 mt.
The ports can be separately enabled / disabled via the menu (see par. 12.6.1).
The two serial ports support Tx and Rx signals only. One serial cable comes with the unit.
