4 Configuration

The ADC-AES has two eight-way miniature DIP switches located near the front of the card.

Groups of 3 switches control the input gain of the analogue inputs. Switches marked 1L and
1R control the levels for converter 1 while switches marked 2L and 2R control the levels for
converter 2. The settings for the level switches are presented in the following table.

4.1 Analogue input levels

0 corresponds to off. 1 corresponds to on.

The three numbers in the top row should be read as: S2,S1,S0.

Switch 1-8 sets the default sample rate. 0 = 48 kHz, 1 = 44.1 kHz.
Switch 2-8 sets the sampling mode. 0 is nominal rate (48 or 44.1 kHz), 1 is double rate (96 or
88.2 kHz).
Note: The external sync input always takes priority for the sampling rate.

The figure below shows the DIP switch SW1 set for + 18 dBu @ 0 dBFS and an internal
sampling rate of 48 kHz.
