4-CHANNEL CLASS D AMPLIFIER WITH 6-CHANNELL DSP · 340 WATTS RMS

The new M4+v3 DSP amplifier can be considered as the little brother of the M6 model. The only difference: The M4+ is coming with four amplified speakers, but still offering more power per channel than the larger M6.  The newly engineered Class D technology is particularly immune to EMC interference, which is virtually indispensable in today‘s electronic-packed vehicles.

A key-premise to enjoy interference-free music while driving. With four bridged power outputs, each one providing 135 watts RMS per channel (2  Ω), the M4+v3 offers remarkable output power with a total of 540 watts RMS. M4 + is perfect for tuning original 4-channel sound systems. Four additional DSP-tunable preamp outputs allow the integration of further amplifiers.

Technology

EPS technology which prevents when connected to an OEM factory radio that nofunctions are impaired or error messages are written into the vehicle memory.

6 -fold laminated board effectively suppresses EMC interference due to the favorable topology.

Bridging amplifier channels enables more flexibility to handle the power.
