DESCRIPTION

8-channel amplifier utilizing Adaptive Voltage Switching Power Supply technology with explosive power and ultra-low distortion.

Peak Power: 280W@4ohm, 170W@8ohm.
RMS power: 220W@4ohm, 120W@8ohm.
Multizone: Bus A, Bus B, and Line In.

The NuPrime MCX-800MZ is a multizone eight-channel amplifier that has four stereo modules, each with its Adaptive Voltage Switching Power Supply technology and integrated amplifier incorporating highspeed gate driver error correction. This technology enables each module to deliver explosive power and ultra-low distortion, with a neutral and detailed sound characteristic. The MCX-800MZ has advanced protection circuitry that safeguards it from fault conditions such as short circuits, overload, overtemperature, and under-voltage.

The Adaptive Voltage Switching Power Supply is the most innovative SMPS design introduced by NuPrime. The amplifier’s output signal feeds back into the power supply’s servo power stage, causing a change in the output voltages supplying the power stage of the amplifier. This design resulted in more details at a low music level and explosive power at a high volume.

Inputs switch:

• L: Each channel has an independent input (Line In)
• B: All inputs are transmitted through XLR cable (Bus B)
• A: All inputs are transmitted through RCA cable (Bus A)

Inputs:

• Switch L position: RCA analog input x 8
• Switch B position: XLR analog input x 2
• Switch A position: RCA analog input x 2

Outputs:

• Stereo Speaker Out x 8
• XLR analog Bus Out x 2
• RCA analog Bus Out x 2
• DC 5V Output x2

Control:

• GAIN Control VR x 8
• MUTE Control x 2
• Trigger in x 1
• Trigger out x 1

Bus Function:

• Bus L: When the switch is in the L position (Line In), each channel has an independent input to drive each corresponding speaker output.
• Bus B: When the switch is in the B position(Bus B), all inputs are transmitted through the Bus B XLR cable, the left channel drives speaker outputs 1, 3, 5, and 7, and the right channel drives speaker outputs 2, 4, 6, and 8 and Bus Output can feed Bus Input of another MCX-800MZ.
• Bus A: When the switch is in the A position(Bus A), all inputs are transmitted through Bus A RCA cable, the left channel drives speaker outputs 1, 3, 5, and 7, and the right channel drives speaker outputs 2, 4, 6, and 8 and Bus Output can feed Bus Input of another MCX-800MZ.
