ALGAM AUDIO MR-702

Rackmount Audio Mixer MR-7027-Channel Mixing designed for professional integration: conferences, fixed installations, events.Comprehensive Connectivity: microphones, RCA line inputs, balanced inputs, balanced main output + Euroblock, RCA recording output.Smart Priorities: priority microphone channel (talkover) + emergency input that overrides all other sources.Robust 1U Rack Format: ideal for technical racks, control rooms, service cabinets.A 1U Mixer Designed for Installation: At the Heart of Clear and Controlled Sound DistributionThe MR-702 was designed as a rackmount audio mixer intended for environments where reliability, clear control settings, and priority management are essential. Its philosophy is simple: centralize multiple sources (microphones, players, console outputs, background music) in a 1U chassis ready for integration, while maintaining precise control over levels and signal hierarchy. In a conference room, event space, place of worship, or corporate installation, it naturally fits between sources and amplification to ensure consistent and secure sound distribution.Who the MR-702 Is For: Conferences, Announcements, and Event Sound ReinforcementThe MR-702 is aimed at audio professionals and integrators who need reliable mixing without unnecessary complexity. Channels 1 to 5 manage microphones (speakers, podiums) or line sources (players, wireless receivers, auxiliary outputs), while channel A facilitates connection of a mixing console or dedicated balanced source. The M channel, a priority microphone, meets the typical needs of installations where speech must remain intelligible: announcements, hosting, moderation, public messages, without manually cutting the music.Key Features: Versatile Connectivity, Priorities, and Front Panel ControlChannels 1 to 5: Mic or Line with Full ControlsChannels 1 to 5 offer a very practical approach for installation: each features a balanced 6.35mm TRS mic input, switchable to an unbalanced RCA line input. This dual connectivity allows quick adaptation of the MR-702 to on-site realities (wired microphones, player outputs, links from existing systems). Each channel has individual gain control, level adjustment, and a 2-band equalizer to tailor clarity and tonal balance according to the room and voices.Channel A (FoH): An Input Designed for Consoles and Balanced SourcesChannel A is designed to accommodate a "master" source such as a mixing console (FoH) or any balanced source. It features two balanced 6.35mm TRS inputs on the rear, complemented by a 3.5mm minijack input with automatic switching when a source is connected. The result: you can easily switch between a fixed link and a temporary source (computer, portable player) without complex operations, while maintaining dedicated level control.Channel M: Configurable Talkover to Always Let the Voice Come ThroughChannel M (Priority Microphone) is the ideal tool for announcements. Its talkover function automatically lowers the level of other channels during speech to improve intelligibility without abruptly "cutting" the audio. The attenuation setting and trigger threshold allow fine adjustment: a discreet announcement in a restaurant does not require the same attenuation depth as a safety message during an event.Emergency Input and Advanced Options: A Security- and Control-Oriented ArchitectureThe MR-702 includes an Emergency input (Euroblock format): upon detecting a signal on this input, the main output disables all other sources to prioritize the emergency message. This function is particularly relevant in installations where audibility of priority announcements must be guaranteed. For further customization, some advanced settings are accessible via jumpers on the PCB, including phantom power activation on mic channels and muting of microphones during an emergency signal.Outputs, Monitoring, and Limiting: A Mix Ready for BroadcastThe main output is available in balanced 6.35mm TRS and Euroblock formats, with master volume control and maximum output level adjustment (limiter). An RCA recording output allows easy capture or archiving of the mix. For headphone monitoring, a 6.35mm Jack output with PFL level control is included, accompanied by a 10-LED meter to visualize the main output level (before any limiter action). Finally, a Mono switch allows summing the main output to mono according to broadcast requirements.Technical SpecificationsChannels and Mixing7-channel rackmount audio mixerChannels 1 to 5: balanced 6.35mm TRS mic input and switchable unbalanced RCA line inputControls for channels 1 to 5: gain, mic/line switch, level, 2-band EQChannel A (FoH): 2 balanced 6.35mm TRS inputs and 1 3.5mm minijack input with automatic switching upon source connectionChannel A controls: levelChannel M (Priority Microphone): balanced 6.35mm TRS mic inputChannel M controls: gain, talkover attenuation control, talkover thresholdTalkover on channel M: automatically lowers music level during microphone announcementsPriorities, Safety, and Advanced SettingsEmergency input (Euroblock format): disables all other sources on main output upon signal detection and broadcasts emergency messageOutput Mute: cuts main output by short-circuiting contactsAdvanced settings via PCB jumpers: phantom power for microphones on channels 1 to 5Advanced settings via PCB jumpers: phantom power for microphone on channel MAdvanced settings via PCB jumpers: priority for emergency microphone (mutes all other microphones when an emergency signal is received on the Emergency input)Outputs, Monitoring, and General ControlMain outputs: 2 balanced 6.35mm TRS and one EuroblockMain output controls: master volume, maximum output level, Mono switch for summing main output to monoRCA recording output6.35mm headphone output with PFL level controlMain output level indicator (before possible limiter action): 10 LEDsConstruction and Interface1U rackmount formatPower button with status LED
