Revoltage WST-IEM-100 Wireless In-Ear Monitoring

Wireless In Ear Monitoring for Cable-Free Stage Performance

The Revoltage WST-IEM-100 Wireless In Ear Monitoring System gives performing musicians a dependable UHF link between the mixing desk and the stage. Working within the 863–865 MHz band, it delivers a personal monitor mix straight to the artist's ears, removing cable clutter that restricts movement. For audio engineers, straightforward inputs and level controls accelerate setup time.

What Sets This Wireless IEM Apart

Equipped with a rack-mountable transmitter and compact bodypack receiver, the WST-IEM-100 is fitted with an external antenna to enhance signal pickup in challenging RF spaces. Musicians remain mobile thanks to AA battery operation, while a plastic carry case keeps all components protected during travel.

Wireless Transmission and Signal Stability

Operating on UHF in the 863–865 MHz band, this model maintains a reliable signal in clubs, concert halls, and outdoor venues where 2.4 GHz systems can falter.

• System: UHF — transmission remains stable and less susceptible to Wi-Fi interference compared to 2.4 GHz alternatives.
• Because the operating frequency is 863 – 865 MHz, performers benefit from a license-free band that's widely accepted across Europe.
• External Antenna — improves reception range and reduces dropouts on larger stages.

Inputs, Outputs, and Power Options

Combo XLR/Jack and 6.3 mm Jack sockets allow the transmitter to accept both balanced and unbalanced sources. Since the bodypack receiver uses AA batteries included in the package, replacements are quick even mid-show.

• Transmitter Inputs: 2 × Combo (XLR/Jack) + 2 × Jack 6.3 mm — supports stereo or dual-mono monitor mixes.
• Plug any standard IEM or the supplied headphones into the 3.5 mm headphone connector output on the receiver.
• Power Supply — AA batteries (included) plus mains adapter for the transmitter.

What's in the Box and Onboard Controls

Arriving as a ready-to-use kit, this instrument includes Volume and Input Level controls so engineers can tailor the mix during soundcheck.

• Quick adjustments are possible on stage using the Volume and Input Level knobs—no menu navigation required.
• Package Contents — Receiver, bodypack, AA batteries, adapter, antenna, rack mount, audio cable, antenna base, earphones, plastic case, manual.
• Color: Black — blends discreetly on stage and in equipment racks.
