The ZVL multi-amplifier synching module allows a user to link, strap, and tune the preamps of multiple amplifiers from a single module. The ZVL was designed to work seamlessly with the new M Series, but it will also work with the DD Audio DM Series as well as other brands of amplifiers.
The ZVL can take the place of several separate components commonly used when setting up multi amp systems. It can replace a line driver, RCA distribution block, external bass knob, and external crossover.
Up to five amplifiers can connect to one ZVL, and multiple ZVLs can be linked together when more outputs are needed.
