  • Page 9: Dxt 3000 System Description

    (UNI ISO 7240-19). MXR 4500 is the main unit with a metallic enclosure for rack-mounting into a 19” rack cabinet (4 units), and it has all necessary components inside for the system operating, included a digital sound processor (DSP) that allows a proper equalization.
  • Page 10 MXR 4500 main unit has a backup power supply that meets the EN 54-4 standard, with recharging unit and check of batteries (18 Ah). To ensure a full system efficiency, it is strongly advised to check batteries every two years and replace them if necessary.

  • Page 11: Unpacking, Installation And Cooling

    MXR 4500 master unit shall be installed into a 19” rack cabinet (4 units) leaving 1 empty unit between other units, in order to guarantee the air flow necessary for an effective thermal dissipation.

    SPARE AMPLIFIER SETTING WARNING: before proceeding with the setting, make sure that the unit is switched off and disconnected from the primary power source and from the batteries. To set the spare amplifier functionality remove the metal flap on the lower left side of the unit’s front panel. Behind the flap set the jumpers as shown in the pictures below.

  • Page 27: Batteries Connection

    BATTERIES CONNECTION System batteries shall be placed on a stable shelf inside the rack (e.g. RCF BH 1042). Each unit requires 4 batteries (12 V – 18 Ah), to be connected together using the dedicated cables, included in the package.
  • Page 28 Connector E shall be linked to the 2 meters long extension cord provided in the package, and then to the connector placed on the unit’s rear panel.

    LOUDSPEAKERS CONNECTION Loudspeakers lines connectors (euroblock) are placed in the upper right side of the unit’s rear panel. For loudspeakers connection refer to instructions shown on the cover label.
  • Page 30 NOTES ABOUT CONSTANT VOLTAGE SYSTEMS • The loudspeaker input voltage (Vd) shall correspond to the amplifier output voltage (Va). • The sum of nominal power values (Pd x n) of all loudspeakers connected to the line shall not exceed the amplifier power (Pa).
  • Page 31 The amplifier board has two outputs (two zones) and the max. overall total power is 500 W (max. 250 W per each zone). The zone number can be increased to 4 or 6 (by adding one or two amplifier boards), but the max. total output power is always 500 W.
  • Page 32 “The recommended tolerance value is the highest of the available options, but lower than the weight of the smallest percentage change in impedance, usually due to the disconnection of the speaker having the highest impedance and installed at the end of a line branch.” An example: a line has a total impedance 80 Ω...
  • Page 33 NOTE : the line impedance (Zline) here is considered at the frequency of 20 Hz (which is not equal to the one measured by an impedance meter at 1 kHz)! In case of a single line having a particularly low impedance load or lines including horn speakers (open circuits at 20 Hz), it will be necessary to add more EOL in parallel.
