Pure Resonance Audio RMA500BT 500W Bluetooth Rack Mixer Amp

500W rack mixer amplifier with Bluetooth for 70V paging and commercial background music

The Pure Resonance Audio RMA500BT is a high-headroom 500W Class D rack-mount mixer amp designed for commercial spaces that need consistent music plus reliable paging. It combines amplification and a 5-channel mixer in one unit, so you can run microphones and music sources without building a stack of separate components.

Why it fits real commercial installs

• 500W Class D power: Strong headroom for busy environments where clarity must hold up at higher volume.
• Built-in 5-channel mixer: Manage mics and music sources in one chassis with simple onsite control.
• Bluetooth streaming plus IR remote: Easy day-to-day playback control for staff without touching the rack.
• 70V and 4–16Ω support: Run distributed 70V speaker systems for long wire runs, or low-impedance speakers when needed.
• Cooling and protection: Variable-speed forced fan cooling plus overheat and short-circuit protection for long operating hours.
• Quick tuning controls: Bass and treble adjustments help clean up speech and shape music for the space.
• Audio Out pre-output (1V): Feed another amp, recorder, or add a future zone without rebuilding the rack.

Best use cases

• Restaurants and retail spaces needing background music plus paging
• Schools, offices, and warehouses requiring clear announcements over 70V systems
• Houses of worship and event spaces mixing microphones with music sources
• Facilities that want one rack unit to simplify both mixing and amplification
