High Power and Flexible Performance
Capable of full-range stereo operation, high-output midbass, or bridged subwoofer driving.
Versatile enough to suit any music genre or system configuration.

Ultra-Low Distortion Design (ULF)
Employs an extremely low-feedback structure to minimize distortion and coloration.
Reproduces transparency and depth close to studio recording quality.

Thermal Tracking Bias (TTB)
Automatically adjusts bias according to operating temperature.
Ensures stable tone and consistent sound quality even during long sessions.

Multi-Stage Isolated Supply Technology (M.I.S.T.)
Separates and supplies power in multiple stages.
Suppresses noise and interference for clean, stable power even under high loads.

Cooling System and Durability
Equipped with a microprocessor-controlled active cooling fan.
Delivers stable performance without compromising sound quality under heavy use.

Pure Signal Bypass
Allows the input signal to be routed directly to the output stage.
Ensures the shortest, cleanest path when paired with external DSP units.

Flexible Configuration
Supports both stereo and bridged (mono) operation.
Ideal for both competition and daily use.

Premium Exterior Finish
Brushed copper and satin silver body with gold-plated terminals.
