Algam Audio MPR 604 - rack-mountable 6-input preamp mixer with USB and FM

The MPR-604 is a 1U rack-mountable preamp mixer designed to provide a flexible, high-performance mixing solution for professional audio installations. It features a 3-channel analog mixer with 2 mic channels, a USB media player, a Bluetooth interface and a FM tuner for a wide range of applications.

A professional audio mixing and distribution solution.
The MPR-604 finds its natural place in a wide range of professional applications, such as commercial facilities, hotels, schools, places of worship and conference rooms. Equipped with a complete mixing section, the MPR-604 features 2 channels in Rca format, with dedicated gain and level, for connecting an external audio source. The 2 balanced jack microphone inputs feature individual gain control, rounded out by 2-band equalization and common talkover settings.
These inputs are mixed to 2 main outputs, each featuring a TRS jack balanced stereo output and an unbalanced RCA output, with a level limiter specific to each output. The Main 2 output features a summing filter and a 100 Hz high-pass filter for better signal control.

Comprehensive connectivity.
In addition to its analog mixing capabilities, the MPR-604 includes a full-featured media player for playing music via the USB port, whose level can be controlled via the Media potentiometer on the front panel. Compatible with MP3 files stored on a USB stick of up to 16 GB, formatted in FAT32, this media player features various playback modes: normal or random sequence, single, continuous or loop playback. It also includes a jingle player, with a single trigger mode for teasers, and a programmed mode for announcements. 3 front-panel buttons let you launch live jingles, in both FM and media playback modes.
Versatile, the MPR-604 integrates a Bluetooth input for sending music from a smartphone, as well as an FM tuner for picking up and broadcasting radio station content.

A system designed for public areas
The MPR-604 is equipped with a dedicated emergency input which, when it receives a signal, automatically cuts the current broadcast to give priority to an alert message in the broadcast system. In addition, the Talkover function on the microphones allows you to temporarily interrupt the music or announcements in progress to give priority to a microphone announcement, for example for an urgent communication, or for simple calls without having to change the channel level.

Robust design for professional use
Designed to withstand the rigors of intensive use, the MPR-604 is built with robust materials and boasts a meticulous finish. Its reliable chassis and connectors ensure superior longevity, even in the most demanding environments. The 1U rack-mountable format allows easy integration into any audio equipment rack, facilitating installation in service cabinets or racks.
