Multi-Zone DAC & Crossover
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.
Four Independent DACs 192kHz / 24-Bit PCM ESS Sabre DACs 1U Rackmount Per-Zone Trigger Outputs
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.
FAQ — ZM4 DAX
How many zones does this unit support?
It supports four independent zones, each with its own DAC section, outputs, level controls, and trigger output.
What digital inputs are included?
Each zone includes optical and coaxial digital inputs for PCM sources.
Can it work with subwoofers or smaller speakers?
Yes. Its output structure includes low-pass mono/subwoofer and high-pass output options that make system tuning much more flexible than a basic DAC alone.
Is it rackmount friendly?
Yes. It is built in a 1U chassis and includes rackmount accessories for installation use.
Who is this best suited for?
It is best for custom installers, whole-house audio systems, and multi-zone applications where high-quality digital conversion and zone-specific output management are required.
