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.

It HAS helped with my energy levels!
Size: 360 Count (Pack of 1)
Might be better to take the powder, because I end up taking 12 of these tablets at a time to get the 6 grams of spirulina I want to take. But because they are simpler and cleaner than a powder would be, I may just stick with this! I have noticed my body has more stable energy on the days I remember to take this. And I can take them on an empty stomach which tells me they don’t have toxins or bad preservatives.

Quality Spirulina, A "Superfood"
Size: 360 Count (Pack of 1)
Google Spirulina if you don't know what it is. In short, it's from algae (in this case) that has been shown to provide many health benefits, and studies are underway to validate other claims. One important value: it is one of the few foods that cover essential amino acids. As I said, do your own research. I'm relating what I read and my personal experience. This is, so far, the best spirulina I've found. It is a raw product, vegan, certified organic (by USDA), and proven "bio-active," meaning for me, I absorb it well. It does have an "algae taste" and mild odor (of same). This is difficult to describe, but call it a mild "hay" tone to the flavor. Since it's a pill, it shouldn't bother you. I did notice it the first few weeks, though. IMPORTANT: Not recommended for anyone suffering from phenylketonuria. Ask a medical professional first.
