HELIX NEXT V TWO 2-Channel Class D Amplifier – 2 x 400W RMS / 800W Bridged

HELIX NEXT V TWO – compact power for DSP-based audio systems

The HELIX NEXT V TWO combines powerful two-channel amplification with low-distortion Class D technology in a compact chassis. Use it in stereo to drive demanding speakers or bridge its outputs to power a subwoofer. Rated output is 2 x 200W RMS at 4 ohms, 2 x 400W RMS at 2 ohms or 1 x 800W RMS bridged at 4 ohms.

Designed to complement standalone DSPs and DSP amplifiers, its DirectDSP RCA inputs maintain a direct, linear signal path without conventional crossover circuits. V-AMP Link provides an additional high-level connection specifically optimised for the speaker outputs of HELIX V series amplifiers, making it a practical choice for expanding an existing system.

Precise setup and flexible operation

The Amplifier Control Panel offers push-button adjustment with LED feedback for gain, input mode and input reference configuration. Auto Gain Ranging automatically matches input sensitivity to the connected source, while manual adjustment is available from 0.5 to 8V in 0.5V steps. An integrated clipping indicator helps with accurate setup. Mono / Stereo Mode enables stereo speaker operation or mono subwoofer use; in mono mode a single input signal is sufficient.

Stabilized Output Power technology and an intelligent regulated power supply help maintain consistent performance as vehicle supply voltage changes. Start-stop capability supports brief voltage drops to 6V, and the compact 44 x 220 x 180mm chassis is the same size as the V EIGHT for coordinated installations.

Installation notes

This amplifier has no built-in high-pass, low-pass, band-pass, subsonic or bass-boost controls. Any required crossover filtering must be provided upstream, such as by an external DSP. Minimum rated speaker impedance is 2 ohms per channel in stereo or 4 ohms bridged; 1-ohm stereo and 2-ohm bridged operation are not specified by the manufacturer. V-AMP Link is designed specifically for compatible HELIX V series outputs and should not be assumed to be a universal factory-radio input.
