Biquad Tuner M1 Professional AM/FM Radio Receiver

Biquad Tuner M1 is a professional AM/FM radio receiver with 40 station memories, balanced XLR outputs and a hi-fi headphone output for precise off-air audio monitoring.

Biquad Tuner M1 is a professional AM/FM radio receiver designed for off-air monitoring of broadcast audio in studios, control rooms and technical sites. It provides high-fidelity reception of one or more stations so engineers can check programme quality, modulation and coverage using the same signal that listeners hear.

The Biquad Tuner M1 tuner covers both AM and FM bands and offers up to 40 memory presets per band, allowing quick recall of monitored stations. Electronically balanced XLR audio outputs on the rear panel deliver clean line-level signals to consoles, monitors or logging systems, and a front-panel hi-fi headphone output with dedicated amplifier lets operators listen directly at the rack or test position with excellent clarity. The unit is optimised for continuous operation and precise monitoring rather than consumer listening, giving stable tuning and consistent output levels.

A digital display shows tuned frequency and memory information, while front-panel controls handle band selection, tuning, memory storage and recall. The compact rack design makes it easy to integrate into existing broadcast or measurement racks without taking excessive space. Tuner M1 is ideal for main studio monitoring, backup chains or regulatory monitoring positions where off-air audio must be supervised and recorded.

Biquad Tuner M1 integrates naturally with off-air monitoring systems such as the
Audemat FM/HD Probe, which adds detailed RF, modulation and RDS analysis to the tuner’s audio monitoring. Its balanced line outputs also connect directly to studio consoles from
Broadcast Warehouse’s mixer range, creating a complete monitoring chain where received audio and technical parameters of your broadcast can be checked side by side.
