  • 100% passive — no power supply required

The IsoFormer™ RCV is intended for use directly in front of an amplifier, audio interface and/or mixer, when the absolute best audio quality and noise immunity are desired, and money's no object!

Running two amps from a stereo pedal will normally result in unwanted ground loop hum and noise. Use the RCV in front of either the left / right amp input to immediately kill the ground loop, eliminating its hum and noise.

The RCV can split your signal between two amps, or one amp plus an audio interface or mixer, without any ground loop hum and noise. And, the included PHASE push-button ensures that you'll never have a phase cancellation issue (which results in a sound that can be described as hollow, thin, not as loud and/or lacking low end or fullness).

For splitting to more† than two amps, just use more of them, a RCV for each amp. Use a patch cable from the SPLIT output of one to the INPUT of another and connect the ISOLATED outputs to the input of each amp. Repeat the daisy-chain for more amps and use the THRU output of the last RCV to feed the input of an additional amp.

The buttons, input and output jacks are decisively arranged so that the RCV can serve as an amplifier head-rack's audio input patch-box or interface, even with daisy-chained RCVs. If the last device or pedal on your pedalboard has a balanced output, use the RCV to receive your ¼" TRS balanced guitar signal over extra long (up to 330ft./100m) distances with the best noise immunity possible — ensuring the tone reaching your amp is flawless and noise-free.

  • Power Requirements: 100% passive

User Manual

See our FAQ page for Axess' history with balanced guitar audio, Eddie Van Halen, and Jensen™ Transformers.

† Multi-Amp Splitter

The number of RCVs that can be daisy-chained for splitting to multiple amplifiers depends on various factors, but a minimum of 2 to 4 (for 3 to 5 amps) is conceivable.

‡ Premium JENSEN™ Transformer

"For over 40 years, Jensen Transformers has set the benchmark for delivering the highest quality transformers, with the widest frequency response, least distortion, best common-mode noise rejection, least phase deviation and maximum signal handling."

Though all Jensen isolation transformers provide impressive performance, our IsoFormer™ RCV utilizes their absolute best transformer, spec'd for the most demanding applications... We set the standard in 2014, you just didn't know it, until now!
