The module contains two amplifiers with separately adjustable amplification levels. Each channel is equipped with an overload display. The module can also be used for stereo signals, e.g. the stereo output of a smartphone.  

Technical Details:

• for higher amplifications the two amplifiers can be daisy-chained 
• different normallling options are available via the rear of the modules with jumpers.
• all inputs and outputs are DC coupled. Thus the module can be used also for the amplifications of control voltages. 

Controls and displays:  

• Level 1/2: manual control of the amplification in the range 0 - about 45.
• Overload 1/2: overload LED, begins to light up for output levels beyond about 10Vpp (+/-5V)

• In 1: audio input 1 (monophonic or stereophonic, see technical details)
• In 2: audio input 2 (monophonic)
• Out 1/2: audio output (monophonic)
