FM VERSION DESCRIPTION ENG

11.8DIGITAL 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).

11.9SERIAL 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.
