Q: Does the Twin Iso require power to work?
A: No. The Twin Iso is completely passive. In other words, it does not employ any chips or ICs that require power to make it work. It uses passive components such as transformers and resistors to perform its tasks. Just plug & play.

Q: Will I notice less output when I use the Twin Iso?
A: Considering that it is completely passive, you may notice a slight drop in level. This is easily compensated with line-level equipment, as there is usually plenty of headroom.

Q: Can I use the Twin-Iso between a keyboard and a mixer?
A: Yes. The Twin-Iso will reduce hum and noise caused by ground loops and provide a good clean signal to the mixer. Just keep in mind that the Twin Iso is a balanced device and both source and destination should really be balanced to get the most out of your unit.

Q: Can I use the Twin Iso with hi-z (high impedance) devices?
A: You can. Just make sure that you connect the ground to pin-1 and the tip to pin-2. Obviously hi-z signals are more prone to noise than balanced signals but this will still work.

Q: Will phantom power hurt the Twin Iso?
A: No. 48 Volt phantom power will simply not pass.

Q: What causes ground loops?
A: What engineers refer to as 'ground loops' are caused by several factors. A 'ground loop' is a noise that is often created when two pieces of electrically charged equipment are connected together and their differing ground reference voltages interact. This is often unpredictable, whereby the system noise may be 'acceptable' in one venue and be absolutely horrendous in another. Transformers isolate the two devices by converting the electrical current into a magnetic field and then back to current. A good transformer passes the signal and eliminates the noise without introducing artifacts.

Q: I heard that some transformers can sound bad?
A: This is true. Cheap transformers tend to use low-quality core materials that can saturate when subjected to a hot signal and this will cause distortion. The Radial Twin-Iso employs high-quality Jensen Transformers that have been designed to handle line-level signals without choking. Alas, good transformers are more expensive!

Q: Can I use the JS2 to stop buzz and hum between two consoles?
A: You could but this is not ideal. The Radial Twin-Iso is specifically designed to do this as it has larger line-level transformers for this purpose. In a pinch, the JS2 will work but you would have to use the mic inputs (not line level inputs) to receive the sub-console signal.

Q: Can I rack mount the Twin Iso?
A: Yes, the J-Rak allows up to 8 units to be rack-mounted in 2 RUs.
