V-Series 4-Channel Class D Amplifier

The NVX VADM4v2 is a compact, full-range Class D 4-channel amplifier designed for car, marine, and powersports applications. It offers a robust 500 watts of total RMS power, with configurations of 80 watts x 4 channels at 4 ohms and 125 watts x 4 channels at 2 ohms. For higher output needs, it can be bridged to deliver 250 watts x 2 channels at 4 ohms. Its V-Series design emphasizes micro-friendly size and marine-grade durability, featuring a conformal coated circuit board to protect against moisture and corrosion. This amplifier includes advanced features such as 4-way protection circuitry (thermal, overload, speaker short, and DC offset) to safeguard your system. It is equipped with balanced differential inputs to minimize noise interference and offers selectable input modes (2 or 4 channel) along with switchable crossovers (FULL, HPF, LPF) with a 12dB/octave slope. Input sensitivity can be adjusted from 0.2 to 10 volts for both low and high-level inputs. The frequency response ranges from 20 Hz to 20 kHz, with a signal-to-noise ratio of 96 dB and total harmonic distortion below 0.1%. Variable high-pass and low-pass filters are adjustable from 40 Hz to 400 Hz. Installation is straightforward, with speaker-level (high-level) inputs supported, and an 8 AWG gauge amplifier wiring kit is recommended. The amplifier's compact dimensions (6.49" L x 3.3" W x 1.48" H) make it ideal for tight spaces, as noted by users installing it in motorcycle fairings, Escalade center consoles, and Jeep Compass dashboards. It comes with a 1-year warranty from the original purchase date.
