The black DB-TPS8A Active Two-Pair Sender from RDL is a two-pair audio sending module compatible with RDL Format-A twisted pair products. This module is designed to be mounted in wall boxes, cabinets, or other enclosures that allow users to connect audio sources and features a black front-panel laminate.

The DB-TPS8A module features a stereo mini-jack input on the front panel. The input is designed to receive standard -10 dBV consumer-level signals from sources such as a computer or personal media player. The input signals are amplified using studio-quality preamplifiers optimized for normal operating levels. The buffered left and right inputs are routed to output cable pairs B and C.

This module drives only two cable pairs and therefore it accepts signals and power from one mic-level or line-level Format-A single-pair sender. One single-pair sender may be chained with the module. A single-pair sender must be set to feed pair A if it is connected together with the DB-TPS8A Sender.

The DB-TPS8A module has a Format-A input on the rear panel. This RJ45 input receives left and right signals from preceding senders and sums them together with the local mini-jack input. This allows multiple DB-TPS8A modules to be connected in series with all the mini-jack inputs remaining active.

The DB-TPS8A Sender is remotely powered through the twisted pair cable from any other module, signal distributor, or RDL power inserter connected to the same twisted pair cable. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. The unit features automatic fused power, hum rejection, low noise, and low distortion for designers and installers looking to work with twisted pair products.

Q: 1. Does anyone know if this provides power to Lavs like the the Cos-11 that require power?

A: While I have not tried it with this particular Lav, Sennheiser did say that this systems wiring scheme is identical to the Sennheiser EW Evolution wireless and is compatible with all mics that are wired for the Evolution wireless.

Q: 2. Will it send plugin power through? This would enable the use of Rode Videomic.

A: It will not send plugin power to a microphone that operates off of plugin power.

Q: 3. What is the deepest table/desktop thickness this stand can be mounted on, i.e. 2.5 inch thick desktop, 3 inch thick desktop, etc.?

Q: 4. Could this work with the larger size v-mount batteries as well?

A: Yes, you can use larger size V-mount batteries with the CAME-TV Mini V-Mount Plate.

Q: 5. Can I ask if these come with the charging docks or do they need to be purchased separately?

Q: 8. Hi can I use this device with my Nikon D5200 to record sound directly from mixer with RCA cable from mixer side and in other is AUX and plug in to this device the gave output to my camera

A: The Kopul CMX-1 is not made for taking a line signal from a mixer. It is made for use with microphones that have a 3.5mm connector. If you want to take a line out from a mixer directly into your camera, you want to look at an adapter that can take line input, like the Kopul CMX-2 instead (B&H # KOCMX2V2). https://www.bhphotovideo.com/c/product/1332706-REG/kopul_cmx_2_v2_two_channel_passive_camcorder.html

Q: 9. If I use a splitter, could I feed audio into the camera and monitor at the same time?

A: No, a splitter may not work properly with headphones since the CMX-1-V2 is a passive mixer that outputs a mic level signal while headphones need a line level signal. The headphone volume would be very low. As a better option, you may want to consider something like the Comica Audio CVM-AX3 Dual-Channel Audio Mixer for DSLRs (B&H# COCVMAX3) which is a two-channel mixer that is powered by a 9V battery and includes many more features that you may find useful, including a dedicated headphone jack. Its two XLR inputs can supply phantom power and also accommodate 1/4" TRS jacks. It also has the the same three mono and stereo 3.5mm mic inputs as the CMX-1-V2, but the inputs on the CVM-AX3 can supply 3V plug-in power. You can use any types of mics and send one signal to the camera. We do have other options that may be suitable for your needs.
