"High power x high sound quality" Fully compatible with genuine multi-channel.

HELIX V-TWELVE DSP MKⅡ is a power amplifier with a built-in next-generation processor that inherits HELIX's traditional sound quality and technology while pursuing genuine multi-channel system compatibility.
The DSP section supports 14ch control and the amplifier section supports 12ch output (maximum 120W x 12ch@2Ω), enabling system upgrades and full multi-control of all vehicles with high sound quality.
Internal processing is 48kHz/24bit. The calculation section is equipped with a 64-bit processor (driven at 295MHz), achieving highly accurate and smooth sound playback. Furthermore, AD/DA uses a high-quality Burr-Brown 24-bit converter.
Boasts overwhelming sound quality performance typical of HELIX, with a maximum S/N ratio of 107dB and **harmonic distortion rate of 0.015%**.
It also supports 12ch high level input and is equipped with an auto power-on function, making it highly compatible with the original system. Furthermore, it is fully expandable with TOS optical input, RCA input, and HEC slot.
