Eight speaker connections across A and B outputs for each of the four channels allow up to eight speaker pairs to be driven from a single 1U chassis.\u003c\/p\u003e\n\n\u003cp\u003eEach zone has its own independent 12V trigger input and audio sensing, so individual rooms can be switched on and off independently. A master 12V trigger input can bring all four zones on or off simultaneously. A bus input with looping outputs allows the ZM4 to receive a source signal and pass it downstream to additional amplifiers without a signal splitter. A speaker-level input enables integration with systems that have no dedicated preamplifier outputs. ProHiFi is an authorised Parasound dealer in India.\u003c\/p\u003e\n\n\u003cp\u003eThe Class AB input stage with premium Class D power stage keeps thermal output low during continuous multi-zone operation. Per-channel level controls, detachable speaker connectors accepting up to 12-gauge wire, mono mode for each zone, and short-circuit and overheat protection with front-panel indicators provide the full feature set for professional and residential installation work. The rack mount kit is included in the box. The power supply accepts 100-250V AC automatically, confirming India 230V mains compatibility.\u003c\/p\u003e\n\n\u003c!-- KEY FEATURES --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0F527F;\"\u003eKey Features\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e120W x 4 into 8 ohm; 150W x 4 into 4 or 2 ohm\u003c\/li\u003e\n\u003cli\u003eClass AB input stage with premium Class D power stage\u003c\/li\u003e\n\u003cli\u003e2 ohm stable; 8 speaker connections (A and B per channel)\u003c\/li\u003e\n\u003cli\u003eIndependent 12V trigger input and audio sensing per zone\u003c\/li\u003e\n\u003cli\u003eMaster 12V trigger input to control all zones simultaneously\u003c\/li\u003e\n\u003cli\u003eLooping 12V trigger outputs for downstream components\u003c\/li\u003e\n\u003cli\u003eBus input with looping outputs for daisy-chaining\u003c\/li\u003e\n\u003cli\u003eSpeaker-level input for systems without preamplifier outputs\u003c\/li\u003e\n\u003cli\u003ePer-channel level controls; detachable connectors (12-gauge)\u003c\/li\u003e\n\u003cli\u003eMono mode per zone; short circuit and overheat protection\u003c\/li\u003e\n\u003cli\u003e100-250V AC automatic; India 230V compatible\u003c\/li\u003e\n\u003cli\u003e1U chassis; rack mount kit included; 437 x 63 x 362mm; 5.5kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- WARRANTY --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0F527F;\"\u003eWarranty:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e3-year manufacturer's warranty\u003c\/p\u003e\n\u003cdiv class=\"ph-warranty-box\"\u003e\u003c\/div\u003e\n\n\u003c!-- WHY CONSIDER --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0F527F;\"\u003eWhy Consider the Parasound ZoneMaster ZM4\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eThe ZM4 is the right choice for multi-room and custom installation applications where four independent zones of stereo amplification need to be powered and controlled from a single 1U rack unit. The per-zone independent trigger and audio sensing allows each room to operate autonomously or all zones to be switched together via the master trigger input. The bus input with looping output, speaker-level input, and eight speaker connections make real-world multi-zone wiring straightforward without additional distribution hardware. Compared to running four separate stereo amplifiers, the ZM4 consolidates zone amplification into one thermally efficient chassis that draws only 60 watts at typical listening levels across all zones.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cspan style=\"color: #0F527F;\"\u003eIdeal for\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMulti-room residential installations requiring four independent stereo zones\u003c\/li\u003e\n\u003cli\u003eCustom installations where per-zone 12V trigger and audio sensing control are essential\u003c\/li\u003e\n\u003cli\u003eSystems using the master trigger to power all zones simultaneously\u003c\/li\u003e\n\u003cli\u003eInstallations without preamplifier outputs using the speaker-level input\u003c\/li\u003e\n\u003cli\u003eHome cinema surround and height channels requiring compact four-channel amplification\u003c\/li\u003e\n\u003cli\u003eRack-mounted systems where one 1U chassis must replace four separate amplifiers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- SPECIFICATIONS --\u003e\n\u003ch2\u003e\u003cspan style=\"color: #0F527F;\"\u003eTechnical Specifications\u003c\/span\u003e\u003c\/h2\u003e\n\n\u003cstyle\u003e\n  .ph-spec-wrap { width: 100%;
