Phenyx Pro In Ear Monitor System PTM-22 - Mono UHF IEM

In this review the Phenyx Pro In Ear Monitor System PTM-22 is evaluated for musicians and presenters who need a reliable, uncluttered stage monitoring solution. The bottom line: it delivers clean mono monitoring with a practical rack-mountable transmitter and four bodypack receivers, making it an attractive option for small bands, house-of-worship teams, and conference AV rigs that prioritize signal stability and straightforward setup over stereo imaging. It stands out for its solid build and simple daisy-chain outputs that help share a single monitor feed across multiple performers.

Key Features

• Mono monitoring: Provides a single, focused audio feed that eliminates stereo phase problems and preserves clarity for vocalists and presenters.
• Dual channel inputs with loop out: Two groups of left/right inputs and LOOP OUT jacks let you daisy-chain the monitor feed to additional systems without extra converters.
• UHF wireless performance: Operates in the 900 MHz UHF band with 2x50 selectable frequencies and a reported 164 ft range for flexible stage movement.
• Rack-mountable design: Metal chassis, removable feet and a rackmount kit allow neat integration into existing stage racks or small studio setups.
• Portable kit: Includes four bodypack receivers, earphones, antennas, batteries and a carry case for easy transport and deployment.

Who It's For

The PTM-22 is best suited for live performers, small touring bands, house-of-worship teams and conference hosts who need a dependable mono in-ear monitoring solution with simple setup and sharing options. Its durability, carry case and rack compatibility make it practical for repeated use in live venues and portable rigs.

It is less appropriate for artists who require true stereo monitoring or complex multichannel personal mixes, since the system is focused on mono operation and simplified distribution rather than individual stereo mixes for each musician.
