RCF MX 3250/4
The RCF MX 3250/4 is a 4 channel voice evacuation master unit from the DXT 3000 system, fully EN54 compliant.
The digital DSP-based master unit is equipped with 4 RCF Class D+ power amplifiers. The total maximum output power (sum of all zones) is 250 W and is freely assignable accross the zones.
Amplifier outputs are for 100 V / 70 V constant voltage speaker lines. Each zone has two outputs (to get redundant lines).
Thanks to its internal digital matrix, each power amplifier can send to its zone a different signal (among all the available, e.g. emergency / routine announcements, pre-recorded messages, background music).
The last fourth amplifier channel can alternatively be used as spare (with automatic change-over) in case of a fault.
The MX3250/4 has an integral backup power supply that meets the EN 54-24 standard, with recharging unit and the necessary EN54-4 circuitry for the DC back-up and check of batteries. (see AC BAT 18)
Furthermore it offers inputs, controls and pre-recorded messages to get a real plug & play solution.
The system can be completed with monitored paging consoles BM 3804 and 6 button extensions BE 3806, allow to complete the installation by adding live announcements. Local single-button paging consoles (not monitored) BM 3022 and background music programs can be implemented as well.
DXT 3000 system has been designed to be wired by using very convenient fire-rated J-TYPE cables for paging console and interlink connections.
- Equipped with 4 RCF Class D+ technology power amplifiers
- Internal power supply with battery charger and space for batteries
- An audio input for a line made of up to four monitored BM 3804 paging microphones for selective announcements (linked in ‘daisy-chain’, with or without additional BE 3806 keyboards, according to the max. number of zones).
- An audio input for a line made of one or more BM 3022 paging microphones (not monitored and linked in ‘daisy-chain’) for general calls only.
- An audio input for a background music source (i.e. MP3 / CD players, tuners, etc.).
- Logic inputs and outputs to interface to the fire alarm system (or others).
- An internal player of pre-recorded messages stored on monitored SD CARD.
