Glensound GS-SW012 - 2-Input Reference Microphone Amplifier

GS-SW012 features two low noise reference microphones amplifiers designed for testing and comparing microphones.

There are two headphone monitoring amplifiers enabling two users to listen to the microphone inputs. A front panel switch selects which of the two inputs is being sent to the outputs. Rather than providing a coarse direct switch between the two inputs when the front panel select switch is operated a quick and clean cross fade is performed between the two microphone inputs.

The microphone inputs use the very latest digitally controlled microphone amplifiers and gain is accurately controlled in 1dB steps. The output of the microphone amplifiers is fed into a low noise and wide dynamic range analogue digital converter (ADC), before being fed into a DSP for cross fade and headphone level control.

Reference Microphone Amplifiers
The very best low noise and distortion microphone amplifiers chipsets from That Corporation are used in our very carefully designed pre-amp. The design of the preamp has been an ongoing love affair over several years with continuous development. This design provides crystal clear sound unaltered by unwanted characteristics.

Wide Dynamic Range ADC and DAC
Having a digital core there would be little point in utilising the best possible microphone amplifiers without backing this up with some of the very best large dynamic range analogue to digital (ADC) and digital to analogue converters (DAC).

Front Panel Display and PPMs
The backlit front panel display shows the gain of the two amplifiers which can be easily adjusted by using the simple up/ down gain controls. The two 7 LED PPMsprovide instant easy to see visual indications of the amplifiers output levels.

Two Headphone Amplifiers
To allow two people to simultaneously monitor the output of the microphone amplifiers two separate headphone amplifiers are incorporated, each with their own output and volume control..

Balanced Output
A balanced analogue output is provided in case the microphone outputs need recording or monitoring on external equipment.
