14 I/O BASIC SETTINGS

14.1 ANALOG AUDIO INPUT IMPEDANCE

The analog input impedance may be set to 600 Ohm, rather than the default 10 kOhm, by moving the two jumpers J1
and J2 on the analog input/output board (see figure below).

J1-J2

INPUT INPEDENCE 604 OHM

INPUT INPEDENCE 10K OHM

14.2 DIGITAL INPUT IMPEDANCE

The digital input impedance may be set to 75Ohm, rather than the

default 110Ohm, by moving the associated jumper on the digital

I/O board (see figure).

110 OHM - AES/EBU

75 OHM - SPDIF

NB the digital I/O board is available as an option
