Designed for use in performance venues, broadcast houses, and broad-scale AV installations, the Jensen Transformers Iso-Max DIN-MS-2P Mic Splitteris a passive, single-channel mic splitter that lets you distribute a microphone signal to two consoles at the same time, while eliminating hum and buzz caused by ground loops. Plug-and-play, with no power required, the unit snaps into place onto a standard 35mm DIN rail, for easy installation in a NEMA electrical enclosure.

The DIN-MS-2P features a premium Jensen mic-bridging transformer, which reduces common-mode noise by as much as 130 dB. The unit delivers a flat frequency response from 5 Hz to 50 kHz, with less than 2° phase shift at all frequencies. It also provides a 48V phantom power return path for use with condenser microphones or active direct boxes.

For safety, the DIN-MS-2P comes equipped with a gray, molded assembly made from UL94-VO flame-retardant Noryl.

Related Questions and Answers

Q: 1. Made in?

A: Made in China

Q: 2. What's the maximum weight it can hold?

A: While there is no specified maximum weight, in general we would recommend keeping the weight of a mic on this stand, without a counterweight, at around 1.5lbs.

Q: 3. Can this spilt audio and mic from an iPhone 11 Pro if connected via Apple Lightning to 3.5mm adapter?

A: It can not.

Q: 4. How do these compare with their On-Stage counterparts as far as weight, durability, and portability go?

A: The Auray MS-5230F Tripod Microphone Stand with Fixed Boom is made of steel and weighs 4.5 lbs. The On-Stage MS7701B Euro-Boom Mic Stand has a fixed boom, is made of steel, and weighs 5.2 lbs. The height and boom length are similar for both stands. The MS-5230F is height adjustable from 36.2 to 63" and has a boom length of 31.5". The base dimensions are 25.6 x 25.6". The MS7701B is height adjustable from 37 to 64" and has a boom length of 31". Its base dimensions are 23 x 23". For the shorter stands, the Auray MS-5220T Short Tripod Microphone Stand with Telescoping Boom is made of steel and weighs 3.5 lbs. The height is adjustable from 22.1 to 31.5", the base dimensions are 19.7 x 19.7" and the boom extends from 19.3 to 33.9". The On-Stage MS7411TB Kick Drum / Amp Tripod Mic Stand with Boom is made of steel and weighs approximately 4 lbs. The height is adjustable from 17 to 27", the base dimensions are 26 x 26" and the boom extends from 20 to 36". All of the stands adjust and fold up in the same manner.

Q: 5. Are the threads on top and bottom 3/8 16 or 1/4 20? Thank you

A: The threading on top and bottom is 3/8", and it comes with a reducer to make the female thread 1/4 20.

Q: 6. What is this boom arm's max weight capacity? The mic I want to use is roughly 3-3.5 lbs with the shock mount.

A: The manufacturer has not specified a maximum weight capacity, but the Auray MS-GIGBOOM is intended for use with lighter weight mics, like a traditional handheld style vocal mic. You may want to consider using something with better counterweight like the Ultimate Support Ulti-Boom Pro Telescoping Microphone Boom (B&H # ULTSMB) which has a 0.65 lb counterweight, or the Atlas Sound B2237 Platinum Design Series 37" Microphone Stand Boom (B&H # ATB2237) which has a 0.5 lb counterweight, or the Atlas Sound PB15EB Fixed-Length 34" Microphone Boom (B&H # ATPB15E) which has a 2 lb counterweight.

Q: 7. Can I use this with a logitech streaming webcam?

A: Some Logitech webcams have 1/4''-20 threading on the bottom like the C922 Pro for example. If your Logitech streaming cam does, then you can use B&H # CAC1361 to mount it to the Auray MS-5230F mic stand.

Q: 8. Can the bag for the 3 stand combo fit more than 3 stands?

A: We would only recommend 3 stands, as suggested, for the Three Mic Stands and Cables Kit with Stand Bag.

Q: 9. What is this arm's max weight capacity when fully extended?

A: This is not a publsished specification. I would keep it under 5 lbs.

Q: 10. Can the arm of this stand be removed so that I can hold it myself? I would like to be able to choose whether the arm is mounted on the stand or handheld, but I can't quite tell from the photos and description of this stand if that's possible. Thank you!

A: The boom arm on the Auray MS-5230T is removable.

[5 Hz to 50 kHz] There was a ground loop after I added the Parasound A21+ to my system. Using my Denon AVR 6500H as the preamp, there was a noisy signal traced to the ground midpoint on the DirecTV antenna cable at the home cable entrance. It is a difficult ground loop because the shield of the DirecTV coaxial cable carries the power for the roof antenna. It would not help to make a single star ground because there is always a length of powered shield between the home theater/stereo boxes and the outdoor grounded entrance (grounded there at the outside wall by electrical) code. Fortunately, the Iso-Max breaks the ground loop at the input the A21+, so other potential ground problems may be cleared as well. While I was very hesitant to add anything to the input analog signal path, this seems to be the best and most practical solution. So far, I do not hear any difference, no perceived distortion or loss of fidelity.

[0.365 lb] This is the second VRD-1FF I've bought. The first one lasted 9 years, but this spring our house was hit by lightning. The old VRD-1FF started adding 6dB signal loss, so I figured the lightning hurt it. Just like the original, the new VRD-1FF has eliminated the ground loop hum that was on our incoming CATV Cable

[1] We got a new cable box for the home theatre and with it a ground loop hum. This filter worked perfectly to get rid of the hum and did not interfere with the digital cable programming

[0.365 lb] Had a 60 cycle hum in my audio/video system and narrowed It down to the Blu-Ray player and cable box were causing a ground loop. Installed the Jensen ISO-Max VRD-1FF on the cable line before the box and it worked - no more hum. Much thanks to Jensen and B&H.

[0.365 lb] I have Denon & Atmos speaker setup, cablebox from Comcast & a subwoofer. The cheap $20 isolator available online didn't do a good job since comcast signal was degraded per their tech. He said that it introduced some noise feed back to their other customers. Not sure how much of that is true but he did say that if I were to get an isolator get something over 1000mhz and this one fit the spec. I installed it and so far all is great. No issues with performance but the box label instructed to read instruction which were not in the box. So I went to their website and read it.

[0.365 lb] The transformer worked perfectly. The low frequency hum from the TV was gone once it was installed. Make sure to follow the installation guidelines on the website - especially trimming the center conductor on the CATV coax cables. NOTE: There were no instructions included with the shipment even though the label on the transformer box seemed to imply there would be.

[0.365 lb] Expensive but knocked out the hum coming from my cable.

[5 Hz to 50 kHz] Great device, bought to fix a ground loop hum between my catv coax coming into the house and my other audio-video equipment.
So now no more hum and the video reception quality did not degrade.

[0.365 lb] Solved the problem of the DirecTV receiver causing ground loop (because of the ground at the home entry). Using a Denon AVR 6500H as the preamp for Parasound A21+, placed the Jensen Transformers Iso-Max CI-2RR - 2-Channel Ground Isolator about a couple of feet from the Parasound RCA input and 3 feet from the Denon (all bluejeans LC-1 capbles). Dead silence now during quiet periods.


The good part about placing the isolation break at the input to the power amplifier is that the Jensen should still be effective should there be other ground problems now or later, beyond the Directv receiver.
