{"product_id":"marantz-model-m4","title":"Marantz MODEL M4 – Multi-Channel Power Amplifier","description":"\u003cp\u003eThe Marantz MODEL M4 is a professional-grade 8-channel distribution amplifier built for whole-home audio systems. Designed in Shirakawa, Japan, it delivers 100 W per channel across four independent zones, making it ideal for multi-room setups. Whether you're streaming music or routing TV audio, the built-in HEOS® engine powers seamless wireless playback, while its robust, rack-mount design ensures stable performance in custom installations.\u003c\/p\u003e\n\u003cp\u003eEach of the four zones can be managed separately, allowing independent streaming or grouped playback. The M4 supports high-resolution formats including FLAC, ALAC, WAV (24-bit\/192 kHz), and DSD. For TV integration, there are optical digital inputs, and with Dolby Digital decoding, you can easily stream source audio into any zone.\u003c\/p\u003e\n\u003cp\u003eFor advanced control, every zone has pre-outs and selectable subwoofer outs with adjustable high-pass and low-pass filters. You also get tone control (bass\/treble), balance, and volume limits, making it highly configurable. The amplifier features Marantz Musical Digital Filtering (MMDF) for refined clarity and texture. With 12V trigger outputs per zone and a bridge mode that increases output to 200 W per 4 channels, the MODEL M4 is both powerful and flexible for any multi-room setup.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e8-channel distribution amplifier with 4 independent audio zones\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e100W per channel (8Ω) with low-distortion digital amplification\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBridge mode: 200W output on 4 channels\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHEOS® built-in for multi-room wireless streaming\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh-resolution audio support: FLAC, ALAC, WAV, DSD\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDolby Digital decoding via optical input\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e4 stereo RCA inputs and 2 optical digital inputs\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e4 stereo pre-outs and 4 subwoofer outputs (one per zone)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAdjustable high-pass (40–250Hz) and low-pass (40–120Hz) filters\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBass \u0026amp; treble EQ ±5dB and balance ±15dB\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVolume limit control for each zone\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSound modes: Stereo, Direct, Virtual, Dialog Enhancer, Night Mode\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTV Sound Grouping for syncing TV audio across zones\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMarantz Musical Digital Filtering for refined sound quality\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e4 × 12V trigger outputs\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRack-mountable design with active cooling\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output:\u003c\/strong\u003e 8 × 100W (8Ω), 8 × 125W (4Ω)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridge Mode:\u003c\/strong\u003e 4 × 200W (4Ω)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz – 40kHz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker Impedance:\u003c\/strong\u003e 4–16Ω\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 4 × RCA, 2 × Optical\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 4 × stereo pre-outs, 4 × subwoofer outs\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilters:\u003c\/strong\u003e HPF 40–250Hz, LPF 40–120Hz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEQ:\u003c\/strong\u003e Bass ±5dB, Treble ±5dB, Balance ±15dB\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound Modes:\u003c\/strong\u003e Stereo, Direct, Virtual, Dialog, Night Mode\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetworking:\u003c\/strong\u003e Wi-Fi, Ethernet, HEOS multi-room\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 415 × 106 × 442 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 8.0 kg\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 year\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Marantz","offers":[{"title":"Default Title","offer_id":43810017443919,"sku":null,"price":374900.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6746\/4527\/files\/modelm4_image_5_na.png?v=1772107044","url":"https:\/\/www.delhiaudio.co.in\/products\/marantz-model-m4","provider":"Delhi Audio","version":"1.0","type":"link"}
