The IsoPlus is small enough that it can be mounted on or under any pedalboard. Alternatively, it can be used directly in front of an amp, at the end of a long cable run from the pedalboard.

Use it anywhere in the signal path to immediately kill a ground loop, and eliminate its buzz, hum and noise. It can also be used to convert a ¼" TS unbalanced signal to ¼" TRS balanced or vice versa, at the end of a pedalboard or right in front of an amplifier, respectively.

An IsoPlus can split your signal between two amps, or one amp and 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).

Need more‡ than two amps? Just use an IsoPlus for each amp. Use a patch cable from the SPLIT output of one to the INPUT of another and connect the XFMR isolated outputs to the input of each amp. Repeat the daisy-chain for more amps and use the SPLIT output of the final IsoPlus to feed the input of one more amp.

‡ Multi-Amp Splitter

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