Studer OnAir 2000M2 - Analog Output Module; Dual Analog Output Module

OnAir 2000M2 Digital Mixing Console
15-8 HW Modules SW V 4.0 Date printed: 12.11.03
15.8 Analog Output Module 1.942.120.xx (with balancing transformers)
The analog output module provides a transformer-balanced, stereo or
mono output signal (jumper-selectable).
The output signal selection is performed on the PCB by means of labeled
jumpers.
Note: In mono mode, the output signals of the stereo DAC are added in the ana-
log domain to increase the converters' dynamic range. Therefore, if the
DAC input signal is a stereo signal, the resulting mono output level is in-
creased by 3 dB referred to the stereo output, and if the DAC input signal
is a mono signal, the resulting mono output level is increased by 6 dB.
These level differences have to be compensated by adjusting the output
level with the two trimmer potentiometers “R ADJ.” and “L ADJ.” acces-
sible from the rear of the module.

15.9 Dual Analog Output Module 1.942.121.xx (with balancing transformers)
The dual analog output module provides a transformer-balanced, dual ste-
reo or mono output signal (jumper-selectable).
The output signal selection is performed on the PCB by means of jumpers;
refer to chapter 16.5.
Note: In mono mode, the output signals of the stereo DAC are added in the ana-
log domain to increase the converters' dynamic range. Therefore, if the
DAC input signal is a stereo signal, the resulting mono output level is in-
creased by 3 dB referred to the stereo output, and if the DAC input signal
is a mono signal, the resulting mono output level is increased by 6 dB.
These level differences have to be compensated by adjusting the output
level with trimmer potentiometers located on the PCB; refer to chapter
16.5 for component locations.
