  • Page 4: Introduction

    Introduction Operating Safety Important security advices The recording industry has gone through some dramatic changes in the past years. The home recording market produces professional results with modest investments. Mainly inexpensive mixing consoles with lots of channels and 8-bus-option are being used.

    The M is equipped with two electronically balanced, female 3-pole XLR sockets to connect two microphones or a line signals. The outputs of the M male XLR sockets as well as unbalanced on 1/4“ jacks.The outputs can be used parallel to each other. This means that two output signals can be produced from one input signal.

    Control Elements Mic Gain Phase Reverse The preamplifier stage of the M semiconductor. The strengths of this particular component are its extremely low noise and distortion characteristics. Unlike discre- tely designed circuits, the SSM 2017 has 64 transistor functions (discretely up to 24), thus achieving a very high common mode rejection.

    2. The phase inversion feature is also very useful when the pola- rity of the XLR input jack has to be inverted to match the polarity of the microphone or the microphone cable.The pin assigment of the XLR connector is as follows: Pin 2 = hot (+) and Pin 3 = cold (-). 3.
  • Page 8: Power Supply

    Power Supply A stable and well-filtered toroidal-core power supply provides the basis for good sound processing. The GND LIFT switch helps to remedy hum loops. Ample filtering, smoothings and calibrations make for stable, constant service voltage. The phantom supply voltage is from a separate power supply with sophisticated filtering and selected components.
