12. Connector Pinouts

TRS jacks of analog input / output

The stereo ¼" TRS jacks are wired according to international standards:

Tip = + (hot)

Ring = – (cold)

Sleeve = GND

The servo balanced input and output circuitry allows to use monaural TS jacks (unbalanced)

with no loss in level. This is the same as when using a TRS-jack with ring connected to ground.

XLR jacks of analog input / output

The XLR connectors are wired according to international standards:

1 = GND (shield)

2 = + (hot)

3 = - (cold)

TRS Phones jack

The analog monitor output on the front

is accessible through a stereo ¼" TRS

jack. This allows a direct connection of

headphones. In case the output should

operate as Line output, an adapter

TRS plug to RCA phono plugs, or TRS

plug to TS plugs is required.

The pin assignment follows interna-

tional standards. The left channel is

connected to the tip, the right channel

to the ring of the TRS jack/plug.

13. Firmware

The current firmware of the ADI-2 is version 1.4. This one is identical to version 1.3, except for a

changed brightness of the white QS LED (formerly orange). Firmware 1.3 (10/2005) includes

these improvements:

- No loud click anymore at changes of the input sample rate

- Support for ADAT S/MUX and S/MUX4 (ADAT up to 192 kHz)

- New function D-D. When the INPUT LEVEL button is pressed a fourth state 'LED Off' has

been added. Instead of the AD-converter signal the digital input signal is fed to the DA-

converter and to the digital output. The Level Meter displayes the digital input data.

- Competely re-programmed ADAT PLL

The firmware version is shown after power-on of the unit on the Level Meters for a brief mo-

ment, with 1 for the lowest and 6 for the highest LED. The left channel shows the first number,

the right channel the second number.
