The Jensen Transformers Iso-Max CI-2RR - 2-Channel Ground Isolator is a passive, unbalanced stereo isolator, which prevents and eliminates hum and buzz caused by ground loops. It ensures that music is faithfully delivered without distortion, coloration or artifact, when used with audiophile systems, home theaters, computer sound cards or any other unbalanced audio signals.

The CI-2RR features a pair of high-performance Jensen transformers, which deliver pristine audio from 10 Hz to 40 kHz, with low distortion across all frequencies. Furthermore, the transformers are shielded in a MuMETAL can to protect against external magnetic fields and prevent "spectral contamination" due to ultrasonic and RF interference.

Easy to set up, with no power required, the Jensen Transformers Iso-Max CI-2RR comes with gold-plated RCA connectors to ensure optimal transfer of the audio signal. The unit is equipped with a rugged steel enclosure that is fitted with screw-down flanges for easy installation in racks or for mounting under shelves and cabinetry.

Q: 1. Will this device eliminate the 60 Htz hum from my mixer to the Atem Mini pro audio inmput?

A: If the 60Hz hum is a result of a ground loop in your system, then yes the Teenage Engineering Ground Loop Noise Isolator With Stereo Cable will work.

Q: 2. How long does it take to charge 150wh batteries? And is it simultaneous?

A: It takes just 3 hours to fully charge eight 45Wh Micros, 5 hours for eight 98Wh Micros, and 7 hours for eight 150Wh Micros to reach capacity. The Bebob Factory GmbH AS4Micro 4-Channel Charger offers 8-Channel Simultaneous Quick Chargers.

Q: 3. 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: 4. LINE input or MIC input or both ?

A: Both.

Q: 5. We use 70V PA systems in our conference room. They have built amplifier and equalizer. Would this transformer go between the equalizer and the amplifier or between the amplifier and the speakers?

A: This transformer is used to send balanced or unbalanced line level audio signals over long distances. It would be placed between an equalizer and an amplifier.

Q: 6. Does this Connecting Cable work with Sennheiser ew 100 ENG G3? Or does it need an adapter of some sort?

A: The Sennheiser CI1 cable will allow connection directly to the mini input on the EW belt pack transmitter with locking connector.

Q: 7. Can this be used with Nikon Z8 camera?

A: Yes, the Beachtek DXA-MAX 2-Channel Active Audio Adapter for DSLR can be used with any camera that has a 3.5mm microphone input jack.

Q: 8. 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: 9. Would this work to get balanced audio from an event sound system properly into an ATEM Mini Pro?

A: Yes, the Sescom 1-Channel Balanced XLR to Unbalanced RCA to Audio Converter will allow you to properly connect the sound system into the ATEM mini.

Q: 10. What is the weight capacity? What grade of alloy is used?

A: The weight of this DigitalFoto Solution Limited HULK-ISO Shock Vibration Isolator, is :0.5~8kg And the Material would be :alloy aluminum+stainless steel wire spring.
