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.

Good quality. Decent price.
Style: Fox, Raccoon, Squirrel
The small size is perfect for my 13# dog, but I was somehow under the impression that one squeaker was in the head while the other was in the tail (and that might be the case for rhe larger size), but one us in the main body, with the other in the tail. The head is flat, and there's no way to push the sqeaker in the body up into the head. Ordinarily, this wouldn't matter -- and my dog LOVES the one I gave him so far; he's squeaking up a storm! -- but I bought these toys specifically so I could fill the (presumably empty, but in reality not) body between head and tail with chopped up pool noodles so my paraplegic dog could take it into the water treadmill treatment he's starting in a couple weeks. I wanted something that would float and be largely waterproof (no fluff inside in case he drops it in the water), that he could hold in his mouth instead of wearing a muzzle. I've rated these toys 4 stars because he does love them, they seem well made, and they're pretty affordable. I would buy them again, though not for the same purpose. (He hates rubber toys, so this was my last hope. Lol?)

Longest lasting dog toys we’ve purchased.
Style: Fox, Raccoon, Squirrel
In 2020, we purchased these for our 6 month old puppy who was repeatedly destroying all of her toys. Christmas 2025, I gifted our dog a stuffed toy purchased from a local dog store. It was destroyed within an hour. Later that day, I found one of these little squirrels that we purchased FIVE years ago - still in action, a bit worse for the wear, but still very much loved by our dog. I decided to purchase another pack of these as they are clearly winners.

The Ad got me, the reality didn't
Style: Variety Pack - Large (3-pack)
Directly from the ad- "Exclusive Noisemakers - Each large toy includes 3 high-quality round squeakers to deliver more sound to keep your best friend entertained.". Now my neighbor bought this squirrel with three high-quality squeakers nearly a year ago. It's ragged and tattered I just recently sewed it up for him where he chewed the one leg odd, but those three noise makers are still squeaking. Whe I got my pup, I immediately went to buy one and they were no longer selling them, so I've been on a search for one or an equivalent. These are not. There's no stuffing to get all over the place when your pup breaks into it, a plus. However the squeakers weren't particularly loud and were silenced in a few hours. Two were dead and the remaining one was very well on its way. The toy itself was pretty much intact but that had more to do with the lack of attention from the dog than how rugged the toy is. He'll pick it up once in a while but it certainly didn't meet my expectations. The good thing is that there are three of them so I can give him some brief excitement in the future. Wouldn't buy again.

Strong Chewer Friendly Toy
Style: Variety Pack - Large (3-pack)
My dog is a rough chewer and these last a really long time (clearly since this beaver's face is long gone! The no stuffing is a win too for cleaning up afterwards.
