AR7000 Series Features
The AR7000 Series are recommended for users planning a full-scale car audio
system. At the core of these amplifiers are Pulse-Width Modulation Regulated
MOS-FET Power supplies, which deliver a more consistent power supply and ensure
that maximum power output and clarity are achieved, even if the input power is
unstable. Arsenal Mono amplifiers also feature Low-Pass and Subsonic filters, as
well as a Variable Bass Boost for more specific low-end response and control. The
2-ch and 4-ch amplifiers also feature both variable Low and High-Pass filters for
even greater system flexibility.
The AR7501D is a class-D amplifier model in the AR7000 Series, featuring a high
power of 1000W RMS x 1@1 Ω, and a massive power supply for handling high
currents.
