Parasound ZoneMaster 4 DAX DAC

Developed specifically to maximize the Sonos Connect®, ZoneMaster 4 DAX transforms the Connect® into a true custom install product

Parasound® has begun dealer shipments of the World's first four-zone DAC and crossover, the ZoneMaster 4 DAX.  The Parasound ZoneMaster 4 DAX frees the custom installer from the four biggest limitations of the Sonos Connect®; sound quality, connectivity constraints, rack space and profitability.  It is the first four-zone single chassis DAC with integrated crossovers, mono outputs, subwoofer connectivity and 12V DC trigger outputs.  The 4 DAX enables custom installers to upgrade their clients' high-resolution digital sound quality and increase speaker flexibility when creating multi-zone systems without the cost and complexity of additional preamps or house audio controllers. The 4 DAX complements streaming devices that have digital volume controls, such as the Sonos Connect®, Bluesound Node®, Google Chromecast Audio®and Apple Airport Express®. Most importantly, it provides a more profitable pathway for whole house audio system systems based around these streaming audio devices.

The Parasound ZoneMaster 4 DAX is a single chassis unit that achieves superior DAC performance by using four premium 192kHz/24-bit ESS DACs when using an optical or coaxial connection. In addition to the ESS DAC, each Zone has premium analogue crossovers with level controls and outputs for full-range stereo, high-pass stereo, full-range mono, high-pass mono and an 80-Hz low-pass mono subwoofer output. Each zone also has an audio-triggered 12V output to activate additional equipment such as amplifiers and cooling equipment. Parasound's own 2-, 4-, 6- and 12-channel ZoneMaster amplifiers have independent trigger inputs for each zone making them a perfect companion to the 4 DAX.

The Parasound ZoneMaster 4 DAX dramatically reduces the rack space and clutter that would have accompanied four separate DACs, four crossovers, plus power supplies and cables, and greatly reducing the time and cost of installation. While the Sonos Connect® traditionally competes in the retail marketplace, Parasound's 4 DAX creates a profitable value-added alternative for the custom installation industry.

"you can tell everyone at Parasound that we are super impressed by the 4 DAX as it transforms a commercial setup combined with several Sonos connects and a Parasound ZoneMaster 450, 650 or 1250. The sound is obviously much more clear, dynamic and involving in these challenging environments..."
