7.2 Analog Outputs
The short circuit protected, low impedance and balanced line outputs are available as (stereo)
1/4" TRS jacks and XLR jacks. Both are internally connected, and can be used simultaneously.
The electronic output stage is built in a servo balanced design which handles monaural and
stereo jacks correctly. When used unbalanced it automatically corrects the gain by 6 dB.
To maintain an optimum level for devices connected to the analog outputs, the ADI-2 includes
a discrete hardware gain stage, directly behind the DA-converter. Electronic switches of the
latest technology, which introduce no additional noise or distortion to the audio path, are used
to control the gain, and offer highest operating comfort. This way, the key OUPUT - LEVEL
allows a convinient adaptation to the most often used studio levels -10 dBV and +4 dBu.
As with the analog inputs, the analog output levels do not follow any single standard, but are
designed to maintain a problem-free operation with most other devices. The headroom of the
ADI-2 is defined according to the chosen reference level.

+4 dBu
-10 dBV
At +4 dBu a headroom of 9 dB offers a problem-free operation with most devices, and meets
the latest EBU recommendations for Broadcast usage. At -10 dBV 12 to 15 dB headroom are
common practice, each mixing desk operating at -10 dBV is able to send and receive much
higher levels. Hi Gain results in maximum level for professional users who prefer to work bal-
anced and at highest levels.
