Designed and hand-built (by Mario) in Canada.

Compatt/X IsoPlus™ is a multi-purpose passive device. Use it as a splitter for 2 or more amps, a ground loop hum and noise eliminator, a signal phase inverter, or as a balanced to unbalanced guitar audio receiver and converter. Affordable, compact, and good enough for Eddie Van Halen‡.

Connect the IsoPlus™ to amps using short standard 1/4" instrument cables. Feed its INPUT with the long cable run from a pedalboard, being driven by either the Compatt/X™ Unity+™, the Compatt/O™ Buffer, or an always on last pedal.

For extra long (up to 330ft./100m) cables between a pedalboard and a backline amp, with greater noise immunity, use a 1/4" TRS balanced cable between the Unity+ and IsoPlus.

For splitting to multiple† amps — just use more of them, one IsoPlus for each amp. Use standard 1/4" patch cables from the SPLIT of one to the INPUT of the next, and connect the XFMR output jack to the input of each amp. Repeat the daisy-chain for more amps. The unused SPLIT of the final IsoPlus in the daisy-chain can feed the input of one more amp.

  • The IsoPlus is a completely passive device and does not require a power supply.
  • Housed in a compact; 3.72 x 1.55 x 1.29in. (94.5 x 39.4 x 32.8mm) and rugged #1590A style die-cast aluminum enclosure.

Compatt/X [kom·patta & kom·patto] are the Italian, feminine/masculine noun translations for 'compact'.

† Multi-Amp Splitter:

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

‡ Balanced Guitar Audio: Axess' History

2001: After several years of building many custom buffers, I decided to offer a standard off-the-shelf buffer — the BS2™ Buffer/Splitter. Since it already had a transformer isolated output, I thought; "why not also wire it to be balanced?" For some reason I decided not to mention it in the BS2 user manual... Perhaps at the time I didn’t think many guys would make use of it?

2004: Eddie Van Halen uses the BS2 on his '04 Dave Friedman (Rack Systems Ltd.) built pedalboard for the reunion tour with Sammy Hagar. The long 1/4" TRS balanced cable from the BS2's Isolated Output ran to a balanced receiver and converter (similar to an IsoPlus) and fed his backline Peavey 5150II amp.

2006: A different Canadian company (that I almost worked for...) released their popular SG* balanced transmitter/receiver.

2014: I designed and developed the Clearlink Send and Clearlink Receive for Mesa Engineering.

2023: AXSGTR® Compatt/X™ Unity+™ & IsoPlus™.

Note: Yes, a couple of other companies have started offering similar products in recent years, and that is their history to share. [Mario]
