Product details
The MPR-604 is a 1U rack-mountable preamp mixer designed to provide a flexible, high-performance mixing solution for professional audio installations. It combines the features of a 3-channel analogue mixer with 2 microphone channels, a USB media player, Bluetooth and a DAB+ tuner to suit a wide range of applications.
A professional audio mixing and broadcasting solution.
The MPR-604 is at home in a wide range of professional applications, such as commercial facilities, hotels, schools, places of worship and conference rooms. Equipped with a full 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, complemented by 2-band equalisation and common talkover settings.
These inputs are mixed to 2 main outputs, each with a TRS balanced stereo output and an unbalanced RCA output, with a level limiter for each output. The Main 2 output features a summing filter and a 100 Hz high-pass filter for improved signal control.
Extensive connectivity.
In addition to its analogue mixing function, the MPR-604 includes a full-featured media player for playing music via the USB port, the level of which 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 incorporates 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 buttons on the front panel can be used to launch live jingles, in both FM and media playback modes.
The MPR-604 is versatile, with a Bluetooth input for sending music from a smartphone, and an FM/DAB+ 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 the music or announcements in progress to be temporarily interrupted to give priority to a microphone announcement, for example for an urgent communication, or for a simple communication without having to intervene on the level of a channel.
Robust design for professional use
Designed to withstand the rigours of intensive use, the MPR-604 is built from robust materials and finished to a high standard. Its reliable chassis and connectors ensure exceptional longevity, even in the most demanding environments. The 1U rack-mountable format allows easy integration into any audio equipment rack, making it easy to install in service cabinets or racks.
