MAX Series
The MAX Series is Fonestar's most capable range of multi-zone PA amplifiers — built for professional fixed installations where power, flexibility and reliability cannot be compromised.
From a single 120W unit serving three zones, to a 480W powerhouse managing five independent areas, every MAX amplifier delivers Class D efficiency, an integrated media player, configurable VOX priority and attenuator control — all from a single rack-mount or desktop unit.
The problem with multi-zone audio
The MAX Series was engineered to eliminate the three recurring pain points in multi-zone fixed installations.
Separate amplifiers, Bluetooth receivers, media players, zone controllers — each one is another cable run, another point of failure, another thing to configure.
Staff can't adjust volume in their zone without going to the rack. Announcements interrupt the whole building. Different spaces end up at the same volume regardless of need.
Overloaded circuits trip protection. Music plays over emergency announcements. Zones go silent after a power cut. Issues that keep coming back long after the installer has left.
The solution
Every MAX amplifier combines the functions of multiple boxes into a single, professionally engineered chassis — so you deliver cleaner installations, fewer callbacks and systems that work exactly as commissioned every time.
Commission each zone independently. Set VOX sensitivity, attenuator priority and input levels once — and hand over a system that's locked, standardised and ready to use. Fewer site visits, fewer support calls.
Each zone has its own 7-position volume control. Background music plays from Bluetooth, USB or FM. Announcements cut through automatically via VOX priority. Chimes signal attention before messages. It just works.

System integration
The WALLMIX wall-mounted mixer connects directly to any MAX amplifier via a single RJ45 cable — carrying both audio and power. Local zone control for the end user, without touching the rack.
Together, MAX + WALLMIX deliver a complete, standardised room audio system: the installer sets levels and parameters once, the user sees only a clean wall panel.

Use cases
The MAX Series is trusted across the full range of commercial fixed installation environments.
"The MAX series, with class D amplifiers, offers precise control of attenuators and inputs in complex installations, as well as ringtones, microphone connection for zone management and input for remote panels. Everything a professional installation needs, without the complexity it doesn't."
Frequently asked questions
The main differences are power output and zone count. The MAX-120Z delivers 120W across 3 zones with USB/FM player. The MAX-240Z, 360Z and 480Z step up to 4 or 5 zones with Bluetooth added to the media player. All share the same Class D design, VOX priority, chime, AMP IN/PRE OUT and 100V/70V/4Ω outputs.
Yes — this is a native integration. The WALLMIX connects to any MAX amplifier via a single RJ45 cable that carries both audio signal and power. No additional cabling or power supply required for the wall panel.
VOX (Voice Operated Switch) priority automatically detects audio signal on a designated mic input and uses it to override lower-priority inputs — muting background music and playing the announcement instead. Sensitivity is configurable per input, so you can set the threshold to suit your space.
In an emergency, the 24V / 3-wire attenuator priority overrides all zone volume settings and forces every attenuator to maximum volume — ensuring emergency announcements reach everyone in every area, regardless of how the local volume controls have been set.
Yes. All MAX amplifiers output 100V and 70V line as well as a 4Ω low-impedance output, making them compatible with virtually all professional PA ceiling and wall speakers.
Yes. All models are designed for both rack installation and desktop use. Rack ears are included.
AMP IN allows you to bypass the MAX's internal preamplifier and feed an external processed signal directly into the power amp stage. PRE OUT lets you take the preamplified signal out to an external processor, DSP or additional amplifier before it is amplified.
Yes — all MAX models use passive cooling with no fan. This means silent operation, suitable for quiet environments such as offices, meeting rooms and classrooms, and fewer mechanical components to fail over time.
