Product Overview
The M70.4D full range class D four channel amplifier is part of the new mini amplifier series product lineup from SENNUOPU Audio. The M70.4D was engineered to be compact, but provide the power and reliability expected out of larger amplifiers. Featuring a high speed MOSFET power supply, and an efficient Class D design, this amplifier is powerful, reliable, and extremely versatile.
The M70.4D makes for a great amplifier in applications where space is limited but power cannot be sacrificed. In addition, this four channel amplifier features high level input connections for those installations that lack an RCA connection. In addition to the high level inputs, this amplifier also utilizes an adapter harness for the speaker outputs allowing for an easier installation.
➤ MOSFET Power Supply
Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output.
➤ Class D
Our Class-D amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency.
➤ Bridgeable
Combine the channels of a 2 or 4 channel amplifier to provide a dramatic increase in power output.
➤ 2 Ohm Stable
2-Ohm stable comfortably powers speakers or subwoofers when in use at 2-Ohms, resulting in more power and volume.
➤ Variable Low Pass Filter
Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.
➤ Variable High Pass Filter
Variable high-pass filter gives you the ability to filter the frequencies that pass through to the full range speakers.
➤ Variable Bass Boost
Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
➤ High and Low Level Inputs
High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units.
