Phenyx Pro, a professional audio brand known for accessible wireless microphones and monitoring systems, announced the PTM-10 GEN2 and PTM-20, two UHF wireless in-ear monitor systems built on the same platform on Kickstarter. The PTM-10 GEN2 is a single-channel system for solo performers and simpler setups; the PTM-20 adds a second independent channel for bands, worship teams, and other multi-performer stages. Both are built to bring stereo, low-noise in-ear monitoring to houses of worship, small live music venues, rehearsal spaces, and touring acts that have outgrown wired monitors but don't need or want to pay for a flagship system.
Both systems share the same UHF platform. Auto Scan finds a clean frequency before the show starts, three-level RF power adjusts output for anything from a large stage to a small room, and 63 channels across the 555-575MHz band, up to 30mW of transmit power, and a range of up to 165 ft are built to keep interference, dropouts and dead zones out of the mix. The PTM-20's transmitter scales from 2 up to 2N bodypacks, so productions can add performers as they grow.
The real difference between the two systems is how many mixes they carry. The PTM-10 GEN2 runs a single, high-quality mix, enough for a solo vocalist, a host or a drummer who needs a dedicated feed. The PTM-20 splits that into two independent mixes on its A/B channels, so a duo act or a vocalist and drummer in a larger band no longer have to share one blend. For bands, worship teams, rehearsal spaces and small touring productions, that's the more practical starting point.
"PTM-10 GEN2 exists because our users asked for it. After the original PTM-10 shipped, we heard directly from performers and engineers about what they wanted improved, and we spent time testing and refining around that feedback. GEN2 is the result, a direct replacement that gives the same users a noticeably better experience. PTM-20 was built alongside it, on the same platform, for teams that need two independent mixes instead of one." said Vivian Lou, co-founder at Phenyx Pro.
That's a difference in how many mixes each system carries, not in sound quality. Both the PTM-10 GEN2's single mix and each of the PTM-20's two mixes support the same mono/stereo switching, so performers can choose a focused mono feed or a wider stereo image with more than 40dB of channel separation. A 50Hz-18kHz (±3dB) frequency response, a signal-to-noise ratio of ≥88dB, and less than 1% total harmonic distortion keep every mix clean, while up to 70mW of output gives most in-ear headphones enough drive to stay clear on a loud stage.
Because no show goes exactly to plan, both systems build in a few ways to adjust on the fly: a limiter for sudden volume spikes, PAD attenuation against overload, a Balance control for left/right preference, basic EQ on the bodypack, and a Lock function to keep settings from shifting mid-show.
Each transmitter connects to a mixer or audio interface through XLR/6.35mm combo inputs, and both systems support rack mounting for permanent installs or touring racks. Every kit ships complete: transmitter, bodypack receiver, antenna, power supply, batteries, manual, and a half-rack mounting kit, so there's nothing extra to source before a show; the PTM-10 GEN2 kit also includes a hard carrying case.
The PTM-10 GEN2 and PTM-20 are available on Kickstarter, PTM-10 GEN2 priced at $199 - 259.99 and PTM-20 priced at $389 - 509.99 respectively.
