Meet the ZM4 DAX

The Parasound ZM4 DAX Four Zone DAC is a purpose-built multi-room audio solution that combines four independent high-resolution DACs and four analog crossover sections inside a single 1U rackmount chassis. It is designed for custom installations, distributed audio systems, and whole-house listening environments where space efficiency, signal flexibility, and reliable zone-by-zone control matter just as much as sound quality.

For integrators and serious multi-zone system designers, this unit solves multiple problems at once by eliminating the need for separate DACs and external crossover hardware for each zone.

Highlights & Benefits

• Four DACs in one chassis — gives each zone its own dedicated digital-to-analog conversion path inside a compact rack-friendly enclosure.
• Flexible analog output architecture — each zone offers stereo full-range, stereo high-pass, mono full-range, high-pass mono, and low-pass mono/subwoofer outputs for more adaptable speaker and subwoofer integration.
• Installer-friendly control features — each zone includes its own 12V trigger output, plus level adjustments for left and right channels.
• Strong digital compatibility — coaxial and optical digital inputs support PCM signals up to 192kHz / 24-bit.
• Clean rack integration — the 1U design helps preserve rack space in larger distributed audio and whole-house installations.
• Purpose-built whole-home performance — the Parasound ZM4 DAX Four Zone DAC is ideal where multiple rooms need high-quality digital audio conversion with better output flexibility than a conventional zone processor can offer.

Technology & Design

ESS Sabre conversion — Parasound equips each zone with an ESS Sabre ES9023 DAC, using high-quality 192kHz / 24-bit conversion to deliver clean, stable audio performance across multiple zones.

Analog crossover capability — unlike a simple zone DAC, this unit includes Parasound-designed analog crossover functionality so installers can better support subwoofers, bass-limited speakers, and more refined system tuning in each zone.

Signal monitoring and integration support — front-panel indicators provide confirmation of digital input lock and analog output activity, while per-zone trigger outputs simplify coordination with companion amplifiers and related system hardware.

In a professionally planned distributed audio system, the Parasound ZM4 DAX Four Zone DAC delivers a rare combination of conversion quality, output flexibility, and installation efficiency.
