Oklahoma City, Okla., November 20th, 2020 -- DD Audio, a manufacturer of high-quality mobile audio products for the masses, is proud to reveal the completely new ZVL Multi-Amplifier Synching Module. This innovative device was designed in conjunction with the new M Series amplifiers, giving users the ability to link, strap, and tune the preamps of multiple amplifiers from a single module for precision control of complex mobile audio systems. The new 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, remote sub control knob, and an external crossover making the set up and wiring of your system easier and cleaner.
Many amplifiers already have on board strapping or linking functions that work well for low to moderate power applications, but when amplifiers are pushed to their limits these circuits have inherent limitations that allow for slight phase shift and signal voltage discrepancies that can limit maximum power transfer and peak performance. By moving the strapping/linking circuit to an external component our engineers were able to eliminate these discrepancies and increase the reliability and performance of high power multi-amp systems. System designers will appreciate the ZVL’s ability to accommodate both preamp strapping and/or preamp linking. This allows the system to be configured to meet the needs of the application whether it be for competition or daily listening.
The ZVL was designed to work seamlessly with the new M Series amplifiers which will be equipped with a special ZVL input. When a ZVL ready amplifier, such as the M Series, is connected to a ZVL all the crossover and gain setting functions will transfer to the ZVL. This allows the installer to perfectly match the preamp settings of multiple amplifiers. For even more compatibility the remote gain knob included with the new M Series and DM Series amplifiers will plug directly into the ZVL for volume control and diagnostic feedback from the connected amplifiers.
Even though the ZVL is a perfect match for the new M Series amps it can also be incorporated into systems using non-ZVL ready amplifiers such as the DD Audio DM Series amplifiers or even amplifiers from other manufacturers. Setting up multiple subwoofer amplifiers with non-ZVL ready amplifiers will require a few more tuning steps, but when properly set up all connected amplifiers will be perfectly matched and ready to drive massive amounts of bass.
Not limited to just subwoofer applications, the ZVL has several configuration options. It can also be used as an active RCA distribution module for full range amps, and it can handle both subwoofer and full range functions simultaneously. Up to five amplifiers can be connected and controlled with a single ZVL, but when more outputs are needed multiple ZVLs can be linked together for unlimited system expansion.
