The D SERIES-BTN44 modules are wall-mounted user Dante audio interfaces that include bidirectional Bluetooth audio, unbalanced analog stereo or mono audio inputs and outputs, and a balanced or unbalanced line-level output. Stereo audio from a compatible Bluetooth-enabled device feeds two Dante network audio channels. Stereo audio connected to a front-panel Mini-Jack or L and R RCA jacks feeds two other Dante network audio channels.

Stereo audio is available to users through a front-panel Mini-Jack fed from two Dante network channels. A rear-panel terminal block provides either a balanced (+4 dBu) or unbalanced (-10 dBV) output from one Dante network channel. That output may feed a variety of RDL wall panels to provide a specific mic or line level output to users, or it may be used to feed the audio power amplifier in the associated audio zone. One Dante channel may be routed back to a connected device through the Bluetooth interface enabling full duplex communication.

The D SERIES-BTN44 modules are powered from PoE. The installer can customize the module name and programming password through RDL Console 2.0 software. These modules feature studio-quality circuits and analog filters to provide audio performance exceeding expectations from consumer interface technologies. High performance, simplicity of operation and efficiency of installation make RDL the best value in professional Bluetooth interfaces.

Clean, comfortable staple for casual business wear
Color: Black, Size: Medium
Every wardrobe needs a sharp black button-down, and this JEMLDL Oxford shirt hits the nail on the head for versatile styling. The fabric has a nice, substantial weight to it—it's classic oxford cotton that feels durable but remains soft against the skin. The fit is tailored nicely without being a restrictive slim-fit, and the integrated back pleat gives your shoulders plenty of room to move without the shirt pulling untucked. It features a traditional chest pocket and a crisp button-down collar that holds its shape under a blazer or worn casually open over a white tee. It washes up great and doesn't shrink up into a mini-shirt after a cycle in the dryer. Pros: Heavy-duty, high-quality oxford cotton weave. Back pleat offers excellent shoulder mobility for active movement. Versatile styling that dresses up or down effortlessly. Cons: Like all quality cotton oxfords, it requires a quick iron or steam to look crisp. Fits true to size, but has zero elastane stretch in the fabric.

Nice Quality, Great Fit, and Very Comfortable!
Color: White, Size: XX-Large, Color: White, Size: XX-Large
I ordered this shirt for my husband, and he is very pleased with it. He says it is a really nice shirt that fits true to size and looks sharp. The fabric has a great, quality weight to it that gives it a structured appearance, making it versatile enough to easily transition from a casual day out to a more business casual setting at work. The biggest selling point for him is how comfortable it is. He mentioned that it feels great against the skin and offers excellent mobility throughout the day, thanks in large part to the classic back pleat design. The chest pocket is a nice, practical addition, and the classic Oxford style looks great right out of the dryer. It is a well made, reliable closet staple that he is already getting a lot of use out of, and we highly recommend it!

An excellent button down that fits well, looks great, and feels as good as it looks.
Color: Navy Blue, Size: X-Large
From the office to dinner and the to church on Sunday, this is a perfect shirt for any situation. It even looks great worn open over a t-shirt with a pair of jeans and boots or tennis shoes. Who said a nice button down needs slacks and dress shoes? It is a cotton?polyester blend so it is lighter weight than a standard cotton oxford. It also isn't as crisp or harsh and it doesn't wrinkle nearly as bad either. The sleeves are a standard long sleeve but they cuff well. The shirt looks great when cuffed too so that helps when it's hot and humid. There isn't really any stretch to this shirt but that isn't a problem becuase it is perfectly true to size. Just follow the size chart and fit is near guaranteed. For only 20 bucks, basically, (22 to be exact), this is a great choice for any situation when a nicer than completely casual look is desired.
