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

I wonderfully versatile athletically fitting summer polo
Color: Lightbluedot, Size: Small
Don't really have any down sides on this polo. It's lightweight yet surprisingly wind resistant, even on cooler days im not losing all my body heat at the slightest breeze. It feels more like a cotton blend while performing like a polyester with the stretch and drying performance. The fit is very athletic, with just enough room in the chest and shoulders while hugging close to the midsection. This polo is quality both in looks, with the collar holding shape and appearance, the faux chest pocket ups the look of the shirt without being a clunky piece with a pocket that bunches up.
Im thrilled with this polo and am buying more colors to have variety with this shirt. Wonderful wonderful value for the money if you're looking for a versatile close fitting shirt without hindering mobility

Great shirt with a couple of very insignificant flaws
Color: Bluedotwhite, Size: Small, Color: Bluedotwhite, Size: Small
Stylish, breathable, great fit, vibrant color, nice attention to detail with the colorway. Check out my photos for a look at the way the pocket colors and fabrics match that of the collar button, and the tiny perforations in the main fabric that allow you to stay cool in this shirt. There are a couple of spots where you can see flaws, but they're not significant enough to me to deduct a star. The flaws are the thread sticking out of the button, and how the collar has a bit of an indentation in it and isn't totally level smooth. It's hard to figure out how to iron the collar without creasing it in a bad location, so this is the way it looks after ironing with my best effort.
All in all, as I've found with the Alex Vando brand, I enjoy their polo/golf shirts a lot - the fit, look, pretty much everything.

Comfortable summer wear. Runs a little big and long
Color: Blueoval, Size: Small, Color: Blueoval, Size: Small
This is a very comfortable polo. I can tell from the features that the shirt is pretty much designed for golf.
- Very light weight like tees for runners. It is see through if not for the printed pattern.
- Definitely breathable, perfect for dry weather region. Will keep you dry throughout the round and does not cling onto the body to inhibit motion. Structure stays crisp throughout the round.
- Stretchable, does not restrict motion during golf, sweat or not.
- Longer length to stay tuck in.
Note:
- It runs big overall. The model shown is 6’1” and he is wearing a Medium. Seeing that, I bought a Small even though I normally wear medium. It fits my upper body perfectly with a little room to spare.
- It also runs a little long. It will definitely stay tucked in throughout the round. However, it is too long for me to wear it untucked. I am 5’ 8”.
Overall I like the shirt’s quality and a reasonable price for a golf shirt. It would have been perfect had it not been a little long for untuck wear.

Stylish, Comfortable, and Very Versatile Shirt
Color: Navygeometry, Size: Medium, Color: Navygeometry, Size: Medium
This is a very nice‑looking shirt and it fits perfectly for my size. The design really stands out, and the blue color with the white accents looks sharp and clean without being too bold.
The collar and buttons are good quality and add a nice, finished touch to the shirt. It feels well made and holds its shape nicely when worn. Comfort is another big plus—it’s comfortable enough to wear without an undershirt, which is great for warmer days.
What I really like is how versatile it is. You can easily dress it up for business casual with a sport coat, wear it with khakis or jeans, as well as for golfing. It works well in a lot of different settings without looking out of place.
It comes in at a good price point for the quality, and it would make a nice gift as well. Overall, a great‑looking, comfortable shirt that offers excellent value and flexibility.

Comfortable Polo Shirt
Color: Lightbluedot, Size: X-Large, Color: Lightbluedot, Size: X-Large
This shirt arrived quickly, and was vacuum wrapped (see photo). The sizing was appropriate, and the fit is comfortable. It still looks great after a few times through the wash. Recommended.
