Doepfer A-119-2 Dual External Input / Amplifier (slimline)
Doepfer A-119-2 Dual External Input / Amplifier (slimline)
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.
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)
Technical details:
- for higher amplifications the two amplifiers can be daisy-chained
- 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
all inputs and outputs are DC coupled. Thus the module can be used also for the amplifications of control voltages.
Width: 4 HP / 20.0 mm
Depth: 30 mm measured from the rear side of the front panel)
Current: +20mA (+12V) / -20mA (-12V)
