JBL CSMA1120 Commercial Series Mixer Amplifier - 1x120WDesigned for commercial and industrial use, the CSMA 1120 Commercial Series Mixer Amplifier from JBL is a mixer amplifier with four mixer channel inputs and one output channel. It's capable of reaching 120W of peak power with 15W per channel.

The volume controls are illuminated so they can be seen

Designed for commercial and industrial use, the CSMA 1120 Commercial Series Mixer/Amplifier from JBL is a mixer/amplifier with four mixer-channel inputs and one output channel. It's capable of reaching 120W of peak power with 15W per channel. The unit's front panel sports volume controls for each channel, as well as a master volume adjustment knob, bass and treble controls, and a power switch. The volume controls are illuminated so they can be seen and operated in darkened environments.

The amplifier, capable of driving both eight and four Ohm loads, can be used with 70V and 100V distributed audio systems without the need for a separate transformer. On its back panel you'll find the mic/line inputs, unbalanced RCA inputs, speaker connections, Hi-Z and phantom power switches, and more. The unit is also equipped with a RJ45 connector for use with JBL CSR-V in-wall volume controls (available separately). 

This Commercial Series mixer/amplifier boasts such features as voice activating ducking (useful for paging over background music), priority muting for channel one's input, and a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes. Also, with an auxiliary output, you may connect to an additional amplifier, though the master volume and tone controls will have no bearing on the resulting signal.

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.

#1 Winterwear Choice
My favorite jacket I own. This jacket is not only one of the most stylish articles of clothing I have, but perhaps one of the warmest. When I bought an XL I got an XL, it fits perfect. Its heavy for a denim jacket, but that means it is built with quality. Not only does it have a clean aesthetic, but it is extremely utilitarian: If you're getting a jacket, you're getting it for a purpose. This jacket serves that purpose, in fact it serves multiple. This jacket has deep pockets, so your valubles don't slip out while standing or sitting. The price for this jacket is phenomenal, and almost unreasonable for the manufacturer compared to the actual quality you get. The materials to make this jacket may be inexpensive or cheap, but they certainly don't don't look or feel that way. If this jacket ever tears or gets ruined, I'm just going to buy another honestly. I highly recommend this jacket to anyone who wants quality, warmth, durability, aesthetic, and a budget conscious choice compared to designer brand apparel.
