Ideal for use in performance venues, broadcast houses, and broad-scale AV installations, the Jensen Transformers Iso-Max DIN-PB Line Isolatoris a passive, single-channel universal line isolator which can be inserted anywhere in the signal chain to prevent and eliminate hum and buzz caused by ground loops. Designed to work with professional, balanced audio systems, it is also capable of attenuating electromagnetic interference (EMI) and radio frequency interference (RFI) problems. The unit is plug-and-play with no power required, and snaps into place onto a standard 35mm DIN rail, for easy installation in a NEMA electrical enclosure.

The DIN-PB features a specially designed Jensen multi-tap isolation transformer that provides galvanic isolation between the input and output, reducing common-mode noise by as much as 125 dB. The unit delivers a flat frequency-response from 1 Hz to 200 kHz, and can withstand signals in excess of +24 dB, without discernible distortion.

Connections to and from the Jensen Transformers Iso-Max DIN-PB are made via removable screw-down wire terminals. The module comes equipped with a gray, molded assembly made from UL94-VO flame-retardant Noryl.

Related Questions and Answers

Q: 1. Does it have to be used with a particular mount?

A: The DigitalFoto Solution Limited HULK-ISO Shock Vibration Isolator is a universal solution. However if you are attaching a DJI Gimbal like the RS3 Pro or RS2 to the shock mount you would need a gimbal base adapter BH #DIPDRS2 https://bhpho.to/3BtjbLM

Q: 2. Will this work on the Leica SL3?

A: The Tentacle Sync Tentacle to DIN 1.0/2.3 Cable (BH # TETD123C) will interface with a Leica SL3 camera. It feeds devices with a DIN 1.0/2.3 input, including the Canon EOS R5 C or Atomos UltraSync ONE TCG. You can also jam-sync any Tentacle device from an external timecode source with a DIN 1.0/2.3 connector.

Q: 3. will this work with a Canon C400?

A: Yes, the Tentacle Sync Tentacle to DIN 1.0/2.3 Cable is fully compatible with the Canon EOS C400 6K Full-Frame Digital Cinema Camera, which features 1x DIN 1.0/2.3 (Genlock, Return, Sync) connector and 1x DIN 1.0/2.3 (timecode) connector.

Q: 4. Good for info on shooting flat and MLUTS? I'm looking at this book and Doug Jensen's Master Class on Vimeo. I'm basically trying to figure out which one to buy as I don't need or want both. I'd rather buy the less expensive book if it has the info I need. What I'm really looking for is some clarification on Cine EI and S-Log and it's function, MLUTs and Look Profiles and scene files and how they operate. I've been working with Sony cameras for a long time. Most of the operation is all very familiar to me, but I'm new to shooting flat and I don't really understand how one thing affects another when it comes to MLUTS and s-log, etc. Any help in making a decision would be greatly appreciated.

A: Hey Brad,Basically I was in the same boat as you, I know Sony cameras inside and out but was new to a camera that shot s-log and had the ability to show a client an MLUT on a monitor so they weren't looking at a flat, unflattering and washed out image that no matter how much you tell them won't look like that when you've finished adding a LUT. Dougs book is great especially when you are out in the field and you need a quick refresher, something you can't do with the video presentation that he also has. I also like the fact that at the end of each chapter Doug, gives his own personal recommendations which really do help. He really is able to break down the camera within each chapter and write it in a way that you automatically understand. Lastly Brad, this FS7 camera comes with way more menu options than even I thought it did and Doug breaks down what every single thing means. He also let's you know how many mbps each shooting style records at. I would definitely recommend this book to you or a friend. Good luck and enjoy the camera, I bloody love it!

Q: 5. In the video you can see a part in between the isolator and the power base of the gimbal. What would that be the bridge between the two?

A: There are several manufacturers that make the DJI RS2 (Power) Base Plate.

Q: 6. I'm thinking of purchasing this unit, but am curious to how you would connect it from your motherboard to PC speakers. I know it has RCA inputs/outputs, and would assume:- Speakers connect to the output?- Motherboard connect to the corresponding input?Only asking, as their website doesn't have an instructional/manual on this...Thanks.

A: The ART DTI will connect from your computers output jack to the RCA inputs of the unit using the correct cable. Output connections from the DTI will depend on the connections available on the speakers or other device to be connected.

Q: 7. What is the weight allowed for this? Can it be used for Tilta Hydra Alien?

A: The CAME-TV Isolator Cradle GS14 bears 5.5kg and can be adapted to Tilta Hydra Alien.

Q: 8. I'm looking for a way to reduce vibration while filming on a boat and am wondering if this could be mounted on a monopod?

A: The DigitalFoto Solution Limited HULK-ISO Shock Vibration Isolator has many mounting points that could be used with a MonoPod. The HULK-ISO will only help with motor vibrations and not the rocking and pitching motion of watercraft.

Q: 9. Will this item be good for my mackie dlz creator for the background like noise hum as well i have shure sm7db and pig hog cable?

A: The Radial Engineering IceCube IC-1 Balanced Line Isolator and Hum Eliminator will not eliminate background noise, but it can remove or reduce humming sounds caused by grounding issues.

Q: 10. How do we attach the Ronin2 mount on this thing?

A: A Ronin 2 can not be mounted directly to the Kessler Crane KillShock Isolator System unless it is mounted upside down so that the Ronin 2 can hand down from the mounting plate. If you were to mount the Ronin 2 in this way you can use the CineMilled R2 Main Mount for DJI Ronin 2 (BH #CICM021) to attach the Ronin 2 to the Kessler Crane KillShock Isolator System.

[1] It does what it's supposed to, providing good isolation. I haven't verified the specs (which are quite good) but I haven't noticed any audible degradation.

[1 Hz to 200 kHz] 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 Hz to 200 kHz] 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.

[0.93 lb] I was getting hum from my REL T9 subwoofer. REL customer service helped me track down the cause to electrical noise originating from my coax Xfinity cable connection and flowing through my cable box and my AV receiver and out to my subwoofer. After adding this ground isolator the hum immediately disappeared.

[1] I have an Onkyo NR5008 serving as a preamp to a Parasound 2250 stereo amp driving my Left and Right channel Tekton Design Double Impact speakers (high sensitivity 4 ohm speakers). Due to the potential current draws, these are on separate 20 amp circuits. The Jensen CI-2RR removed all the hum without changing the tonal balance or shaving off the high frequencies based on REW measurements. Bought this based on the success I had with the Iso-Max Sub-2RR I use to connect the Onkyo with my 1,000 watt subwoofer amplifier (plugged into a third 20 amp circuit). Both Iso-Max units eliminated the hum without sonically damaging the signal which was not true for the less expensive isolating transformers I tried first.

[1 Hz to 200 kHz] 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.

[0.93 lb] 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.
