Page 2: General Description
The MADA-2 has AES3 and SPDIF digital inputs and outputs, as well as a Word Clock input and output. Analog inputs and outputs are balanced and floating so that they can used with either balanced or unbalanced signals. -

Each time you power up the MADA-2, the “Over” LED will light up. Press the reset switch to turn-off the Over LED. - Page 4 MDAC board inside the MADA-2 that will allow you to change the level calibration for the DA section. Digital inputs There are two digital inputs on the MADA-2. One is configured as an AES-3 or AES/EBU input, and the other is an SPDIF input. The AES-3 input is a 110 ohm, transformer isolated, and balanced XLR input.
