Product Details

500W Rack Mixer Amplifier for Music, Paging and Announcements

The Pure Resonance Audio RMA500BT is a 500W 5-channel Class D rack-mount mixer amplifier designed for background music, paging, announcements, and distributed-audio systems. It combines speaker amplification, microphone mixing, Bluetooth streaming, USB and TF media playback, FM radio, tone controls, and emergency-priority functionality in a compact 1U chassis.

The RMA500BT supports both 70V distributed speaker systems and compatible 4–16 ohm low-impedance speakers, making it suitable for restaurants, schools, retail stores, offices, warehouses, fitness facilities, hospitality spaces, and other larger multi-speaker installations.

Who Should Choose the RMA500BT?

Choose the RMA500BT when you need a high-power rack amplifier that can handle background music, microphones, paging, and multiple speakers from a single unit.

Its 500W output makes it especially useful for larger 70V speaker systems where lower-powered mixer amplifiers may not provide enough system capacity.

500W Class D Amplification

The RMA500BT provides 500W of rated Class D amplifier power.

The efficient Class D design helps keep the amplifier compact while supplying substantial power for distributed music and paging systems.

70V and 4–16 Ohm Speaker Outputs

The RMA500BT supports 70V distributed-audio systems as well as compatible 4–16 ohm low-impedance speaker loads.

For 70V systems, add the transformer tap wattages of all connected speakers and keep the total connected load below the amplifier's available power with appropriate operating headroom.

Important: No 100V Output

Pure Resonance Audio specifies 70V and 4–16 ohm speaker outputs for the RMA500BT. A 100V speaker output is not listed for this model.

Bluetooth, USB, TF Card and FM Playback

The built-in multimedia player supports Bluetooth streaming from compatible phones, tablets, computers, and other source devices.

You can also play compatible audio from USB thumb drives or TF cards, or use the built-in FM tuner. FM reception can vary by location and interference, so it should not be relied on as the primary source for critical playback.

Four Microphone Inputs and Two AUX Inputs

The RMA500BT provides four microphone inputs and two AUX inputs for paging microphones, media players, computers, and other compatible sources.

This allows multiple music and voice sources to be managed from the same amplifier.

Emergency Priority Input

A dedicated EMC emergency input takes priority over normal program audio.

When activated by a compatible emergency voice or announcement source, the amplifier interrupts other audio so the priority message can be heard clearly.

Audio Pre-Output

The RMA500BT includes an AUDIO OUT pre-output rated at approximately 1V ±50mV / 100 ohms for connection to compatible downstream audio equipment.

This can be useful when additional amplification or system expansion is required.

Front-Panel Tone Controls

Low- and high-frequency tone controls provide approximately ±10dB of adjustment at 100Hz and 10kHz.

This allows basic tonal adjustment to better match the connected speakers and listening environment.

Forced-Air Cooling and Protection

A variable-speed forced-air cooling fan helps manage operating temperature during extended use.

Built-in overheat and short-circuit protection help protect the amplifier during abnormal operating conditions.

Compact 1U Rack Design

  • Height: 1.73" (44 mm)
  • Width: 19.05" (484 mm)
  • Depth: 12.4" (315 mm)
  • Weight: 11.5 lb (5.2 kg)

Power Requirements

  • Input voltage: 110–120V AC, 60Hz
  • Power consumption: 650W

What's Included?

  • 1 Pure Resonance Audio RMA500BT mixer amplifier
  • IR remote control
  • Power cord
