4X DUAL Series

Two For One.

No Compromise. The 4X DUAL combines the power and the safety of two completely separate amplifiers in one chassis.

Wear-free digital potentiometers, an integrated Noise Gate per channel, sequential remote power on, computer control, detachable connectors.

That’s what we call Intelligent Power!
