Description
The Radial ProISO solves a common studio headache: mismatched gear that speaks different electrical languages. This passive stereo unit converts balanced +4dB professional line level down to unbalanced -10dB consumer level, letting you connect studio equipment to gear that wasn’t built to talk to it directly.
- Passive design — no power supply, no batteries, no noise floor added by active circuitry
- Converts balanced +4dB signals to unbalanced -10dB output
- Stereo XLR configuration for two-channel signal paths
- Optimized for voice range applications
Because it’s passive, the ProISO stays out of the way sonically. There’s no coloration, no extra hiss, and no need to find an outlet or worry about ground loops introduced by an active converter. Just patch it in between mismatched line-level devices and let the transformer-free circuit handle the conversion.
It’s a small piece of gear that solves a specific, recurring problem: getting professional balanced outputs to play nicely with unbalanced consumer or semi-pro inputs, or vice versa, without introducing hum, noise, or level-matching headaches. For voice-focused recording chains where you need a dependable bridge between equipment standards, the ProISO is a straightforward fix that stays reliable session after session.
