Omnitronic Airbros MK2 5.8G Instrument Kit wireless instrument system 5.8 GHz

The Omnitronic Airbros MK2 5.8G Instrument Kit wireless instrument system operates in the 5.8 GHz band and provides cable-free audio transmission for electric instruments. The kit is designed for live performance and rehearsal use, offering a compact transmitter that connects to an instrument and a receiver that routes audio to an amplifier, mixer or PA. The system targets musicians who need a portable wireless solution for guitars, basses and other active or passive instruments with standard instrument outputs.

Advantages

The Airbros MK2 system removes the physical restrictions of cables, reducing stage clutter and the risk of cable-related trips or signal interruptions. Operating in the 5.8 GHz band, it minimizes interference from crowded 2.4 GHz networks and typical UHF sources in live environments. The kit’s compact form factor and straightforward connectivity make setup and transport simple, while the digital radio link maintains consistent audio transmission suitable for stage monitoring and front-of-house routing.

Suitable for

• Guitarists and bassists seeking a portable wireless instrument link
• Small bands and solo performers for live gigs and rehearsals
• Stage setups where cable management and mobility are priorities
• Backline use to route instrument signal to amps, mixers or wireless IEM systems

When it may not be suitable

The system uses the 5.8 GHz frequency band, which may be subject to different regional regulations and variable propagation characteristics compared with lower-frequency wireless systems. In very large venues or environments with many physical obstructions, the effective range can be reduced compared with lower-frequency systems. Users needing certified operation in specific countries should verify local regulatory requirements before relying on the kit for professional touring.

Key specifications

• Operating frequency band: 5.8 GHz
• Designed for instrument-level audio signals (guitar, bass, etc.)
• Compact transmitter and receiver form factor for stage use
• Audio connectivity: standard instrument jack on transmitter; receiver output suitable for amp or mixer input
• Portable and battery-powered transmitter (battery type and runtime depend on usage)

How to use

Connect the transmitter to the instrument’s output jack and mount or clip it as needed for comfortable playing. Power the transmitter according to the supplied battery instructions and switch on the receiver, connecting its output to an amplifier, mixer or PA input. Pair the transmitter and receiver following the kit’s pairing procedure, then set levels on the instrument and the receiving device to achieve the required signal without clipping. Position the receiver within line of sight where practical to maintain a stable radio link during performance.

What to consider before purchase

• Confirm that 5.8 GHz wireless operation is permitted and suitable in your country or venue
• Assess expected on-stage range and potential obstructions in your performance spaces
• Check compatibility with your instrument’s output type and the required input on your amp or mixer
• Consider spare batteries or power options for extended use

Usage recommendations

For reliable operation, use fresh or fully charged batteries, keep the receiver clear of large metal obstructions, and perform a soundcheck that includes moving around the intended performance area to verify consistent signal quality. If multiple wireless systems are used on the same stage, plan placement to reduce potential radio congestion and test for interference before the show.
