The ADL 600 utilizes a unique high voltage, Class A discrete design with three vacuum tubes per channel for maximum headroom and tonality. The ADL 600 is built by hand in the USA by PreSonus and utilizes the finest components in the world including switched attenuators, military-grade vacuum tubes, analog VU and LED meters, custom-designed proprietary transformers, and the list goes on. No expenses are spared with the ADL 600 down to the last polypropylene film capacitor. The ADL 600 is big, warm, smooth, and clear; a sound like no other.
