``Ultra-high-speed processing and ultra-high sound quality'' Full multi and active systems can be done with this one unit.

HELIX V-EIGHTEEN DSP is a class D amplifier with a built-in HELIX top-class processor that combines a 20ch DSP processor and an 18ch digital power amplifier.
Achieves maximum 20ch DSP control and 18ch amplifier output (maximum 160W x 6ch), and is compatible with everything from genuine multi-speaker systems to full active configurations.
Equipped with high-level 18ch input, it has excellent compatibility with genuine audio.
Equipped with two 64-bit processors (295MHz drive) + 32-bit coprocessor inside, all settings such as time alignment, level, EQ, etc. are reflected at high speed and with high precision.
AD/DA uses high-quality 24-bit Burr Brown, achieving overwhelming sound quality with **S/N ratio of 107dB and distortion rate of 0.015%**.
In addition, the **SCP terminal (changed from CONTROL terminal)** enables smart connection and power supply to the external controller "DIRECTOR".
