Module A-119-2 is kind of a dual version of module A-119 without envelope follower. Instead two amplifiers are available and the module width is 4 HP only.
The module contains two amplifiers with separately adjustable amplification levels. Each channel is equipped with an overload display. The module can be used also for stereo signals, e.g. the stereo output of a smartphone.
Technical Details:
- For higher amplifications the two amplifiers can be daisy-chained
- All inputs and outputs are DC coupled. Thus the module can be used also for the amplifications of control voltages
- The amplifiers invert the incoming signal and can be used as replacement of the obsolete module A-175 (dual voltage inverter)
- Normalling options: the signal applied to socket In 1 can be normalled to socket In 2 in different ways by means of a jumper on the PC board:
- Socket In 1 is connected via a mono patch cable (standard patch cable) to a monophonic signal and this signal is normalled to socket In 2 (i.e. the same input signal for both sub-units): jumper on pin header JP2 in upper position
- Socket In 1 is connected via a 3.5 mm stereo TRS cable to a stereophonic signal and the second channel of the stereo signal is normalled to socket In 2: jumper on pin header JP2 in lower position
- No normalling: jumper is removed from pin header JP2
