The Fostex RM-3 is a high-performance 1U rackmount stereo monitor speaker system built to meet the needs of professional environments where space is limited but accurate audio monitoring is essential. Whether you’re working in a broadcast machine room, surveillance center, or mobile control unit, the RM-3 delivers reliable sound with clarity and flexibility.

Equipped with a powerful 10W + 10W Class-D amplifier and elongated 110 x 40 mm anti-magnetic cone speakers, the RM-3 provides excellent audio performance for its size. It supports analog (XLR and 1/4" TS) and digital AES/EBU inputs, offering seamless integration into diverse setups. Its digital and analog THRU outputs allow for signal pass-through, while the headphone output enables quiet monitoring when needed.

Professional-grade 26-dot LED meters for both left and right channels ensure precise level monitoring, with brightness and meter behavior (VU, peak, hold) fully adjustable. A programmable mute switch adds user control, either for complete silence or a -20 dB drop.

With selectable Voice and Music monitoring modes, the RM-3 adapts to spoken word or full-range audio material, making it an indispensable tool for critical listening in tight spaces.
