INTRODUCTION
DESIGN FEATURES
Thank you for purchasing the DD Audio ZVL (Vari-Link). The ZVL is a Multi-Amp
Sync Module that can take the place of several separate components commonly
used when setting up multi amp systems, making wiring your installs easier and
cleaner.
The ZVL can be simultaneously used as a master volume and preamp controller
for multiple sub amps and an active RCA distribution module for full range amps.
Multiple ZVL units can be linked together when more outputs are needed.
The ZVL can be used with any amplifier but it was engineered to work
seamlessly with DD Audio Amps equipped with a ZVL INPUT. To ensure ease of
use and proper setup please take a moment to thoroughly read through this
manual. We hope you thoroughly enjoy this product, and if you have any
questions regarding installation or setup please contact the DD Audio technical
support team.
!!WARNING!!
Severe Amplifier and Subwoofer damage
can result from improper installation and
setup of the ZVL. PLEASE take time to read
this manual carefully and contact a DD Audio
technician if you have any questions.
