Algam Audio MZR 1005 - rack-mountable 5-input stereo mixer/zone 3 zones

A Mixer/Zoner Designed for Audio Distribution in Professional Environments

The MZR-1005 belongs to the category of audio management tools for installation: it does not aim to "perform" like a live console but to ensure reliable, clear, and controllable distribution on a daily basis. Its approach is straightforward: centralize multiple sources (background music, TV, player, control room, smartphone) and intelligently distribute them to different zones, with necessary priorities for announcements and safety.

Its 1U rack-mountable format facilitates neat integration in a technical cabinet or 19-inch rack, with a control logic separating front panel adjustments (routine operations) from rear panel settings (installation adjustments).

Who Is the MZR-1005 For and What Are Its Applications?

The MZR-1005 is particularly suited for bars, restaurants, shops, hotels, coworking spaces, or any establishment seeking multi-room sound system without unnecessary complexity. It allows different music to be played in each area, maintains consistent volume levels, and keeps control over microphones (announcements, reception, events) without needing to adjust each source individually.

It is also suitable for installations where zones require different behaviors: for example, a stereo zone for the main room, a stereo zone for a second space, and a mono zone dedicated to a corridor, restroom, entrance, or point of sale.

Multi-zone Control, Priorities, and Connectivity: An Efficient Installation Logic

5 Stereo Inputs and 2 Microphones to Centralize All Your Sources

The MZR-1005 provides 4 channels with line-level RCA inputs and gain control, routable to zone outputs. A 5th channel is designed for specific needs: it is only routable to zone C and has no gain control. For "plug and play" use, a 3.5mm mini-jack auxiliary input on the front panel allows quick connection of a device, routed to channel 1 via the AUX>IN1 button.

Two microphone inputs in balanced 6.35mm Jack format complete the set. Each mic has gain and volume controls, a shared 2-band EQ, and a general talkover activation switch to facilitate announcements.

Three Independent Zones: 2 Stereo + 1 Mono

The core of the MZR-1005 is its management of 3 zones: zones A and B are designed for stereo output, while zone C offers a mono output, useful when only one speaker or a mono amplifier is used. On the front panel, each zone features a source selector, master level, microphone level, a microphone signal exclusion function (very useful to prevent announcements in certain areas), as well as options like mono summing depending on the zone.

For fine-tuning during installation, the rear panel offers a 2-band EQ per zone, a talkover attenuation level adjustment, and a Euroblock input dedicated to remote volume control. Finally, a 5-LED level meter per zone provides a quick visual reference of the output.

FOH, Emergency, Output Mute: Key Functions for Public Venues

The MZR-1005 includes a stereo FOH input (rear panel) and a mini-jack auxiliary input (front panel) that can be routed to all zones, replacing the RCA input of channel 4 (for FOH) or channel 1 (for AUX). This is a practical solution when a "control room priority" source needs to take control without rewiring the installation.

For environments requiring strict priorities, the Emergency input in Euroblock format allows, upon signal detection, to disable source playback on the main output and broadcast the emergency message. The Output Mute function allows cutting the main output by short-circuiting contacts, useful for integrating an external cut-off device.

Finally, advanced settings via jumpers on the PCB offer installation adjustments: phantom power for microphones 1 and 2, high-pass filter for microphones 1 and 2, and management of microphone muting on different zones when a signal is present on the Emergency input. These options allow adapting the system behavior to the actual site constraints (intelligibility, safety, priorities, internal compliance).
