8 Mono input & 3 Stereo Input Monitor Mixer with DSP - 1U

General
The Glensound GS-MM83 is an 8 mono and 3 stereo input audio monitor 1u subrack (sometimes referred to as a pre hear unit). The GS-MM83 allows production personnel to control and listen to various programme and communication sources.

Front Panel
From left to right, the first eight potentiometers are mono sources, which have indicators for signal presence and left/right/both signal routing switches. The last three potentiometers are stereo sources, which also have indicators for signal presence, left/right/both signal routing switches, as well as a left only, both, right only, signal routing switches from the individual stereo inputs.

There is a front panel Loudspeaker that is driven via a DSP, volume control, cut switch, dim switch and a control for the dim level, when either the front or external dim switches are activated.

Both 6.35mm and 3.5mm headphones are fitted with a potentiometers to control both outputs the insertion of headphones will cut the front panel loudspeaker. 

Rear Panel
All rear panel balanced inputs are mounted on 3 pin Xlr's except input 9 which is a 3.5 mm stereo jack socket.

Outputs on the rear panel include a pair of stereo 3 pin Xlr's for a set of un-powered monitor loudspeakers, a pair of terminals for powering an external loudspeaker. A switch on the rear panel selects the front or rear loudspeakers and a second switch selects the preset equalisation mode that that the user requires for their loudspeakers. 

Potentiometers provide control of the three separate loudspeaker outputs on the GS-MM83.

A 9 pin D type connector enables remote control of the cut and dim functions on the GS-MM83 monitor panel the wiring is listed below:
      Pins 6,2 = External cut loop
      Pins 3,8 = External dim loop
      Pins 1    = Chassis

DSP
At the heart of the GS-MM83 is a DSP, which is used to control the signal paths to the loudspeaker outputs and the logic functions (cut and dim). The filters in the DSP have been optimised to provide the very best performance for voice or music situations, as well as a third position for a flat eq response if required. The eq functionality is implemented by using the rear panel switch and rear panel indicators.

PSU
The GS-MM83 uses a high quality switch mode supply and requires an external supply of 100 -240v AC and 50/60Hz.

Holes in brackets are not spaced for studs!
Color: White, Number Of Shelves: 2, Size: 67"W x 6.5"D
So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.

These floating shelves look great and were easy to install. The invisible brackets give them a clean, modern look, and they feel sturdy once mounted. Perfect for adding storage or décor in a bathroom, living room, or bedroom. Great quality for the price.
