Product Description

The InterM PMU120N Mixer Amplifier is the latest network-enabled commercial amplifier from this leading professional audio brand.
This 120W, 6-input Mixer Amplifier features state-of-the-art, built-in media player functions never previously available in an InterM product.

The PMU-120N features a built-in USB sound card / media player – allowing playback of MP3 / WMA / WAV audio files directly from a USB media stick (without the need for an audio player device such as CD / MP3 player).

The PMU Mixer Amplifier range now features internet radio capabilities – without the need to connect to a PC / smart phone, etc*.
Using a direct network connection to the PMU amplifier, its on-board processor will provide from the almost limitless choice of internet radio channels to be played through the amplifier – making it a fantastically flexible background music solution.
Internet radio connectivity is via a network / LAN / WAN and TCP-IP or RTSP.
(*Internet radio channels are initially chosen and set using a temporary PC / laptop connection and web browser)

The PMU120N Mixer Amplifier is also compatible with Inter-M’s new AOE212N Audio-over-Ethernet Transmitter – a brand new PA distribution device which allows for audio content or paging to be distributed over standard network connectivity to one or many receivers / amplifiers in a building, campus or multi-site PA system.
In such a system, the PMU120N acts as both Amplifier and audio-over-IP Receiver, allowing for huge flexibility and control in long distance, multi-zone / multi-site audio distribution.

The new PMU Series Amplifiers feature a built-in 2.8” LCD colour display on the front face, displaying operation status, internet radio channel, output level, USB MP3 song title / artist / album / cover art, etc.


The PMU120N also includes more ‘conventional’ features, of course; including 5 selectable microphone / line level inputs, telephone input and dual RCAs (stereo-to-mono sum), as well as mini-jack connector to the front of the device for easy connectivity of portable source devices such as iPhone / smart phone, iPod / MP3 player, CD / DVD player, etc.

Inter-M’s PMU Mixer Amplifiers feature Switch Mode Power Supplies (SMPS) to ensure greater energy efficiency and reduced power consumption compared with traditional amplifiers.
SMPS also ensures reduced heat dissipation and allows for reduced physical size and weight of the amplifier.

The PMU120N Mixer Amplifier provides outstanding value-for-money and functionality for installed public address and background music applications. Ideal for a wide variety of commercial environments including bars / pubs, retail outlets, education, restaurants, fitness centers, dance studios and training facilities.
