Its IP66-rated front panel is intended for exposed helm and console installations where water and outdoor conditions are a concern. The large color display and physical controls provide a direct way to manage sources and volume while underway.\u003c\/p\u003e\u003cp\u003eThis receiver is suited to boat owners building or updating a 12-volt marine audio system with up to four 4- to 8-ohm speakers. Its internal amplifier is CEA rated at 22 watts RMS per channel into 4 ohms, with a stated maximum output of 50 watts x 4 at 4 ohms. Separate zone controls help adapt playback levels for different listening areas on the vessel.\u003c\/p\u003e\u003cp\u003eThe HMR 20 supports two independently controlled audio zones through dedicated stereo RCA line outputs for Zone 1 and Zone 2. A separate subwoofer RCA output is also provided for adding an external marine amplifier and powered subwoofer system. Per-zone bass, treble, balance, loudness, zone naming, and maximum-volume settings support practical system tuning.\u003c\/p\u003e\u003cp\u003eA 3-inch color TFT IPS display with 640 x 360 resolution provides source, track, station, and voltage information. Bluetooth 5.0 supports wireless audio streaming with compatible A2DP and AVRCP devices, while USB playback supports MP3, WMA, and compatible 16-bit\/44.1 kHz WAV files. AM\/FM reception includes RDS where available, and the receiver is DAB+ ready when used with the optional Hertz HMB DAB+ module.\u003c\/p\u003e\u003cp\u003eThe HMR 20 is built for 12-volt negative-ground electrical systems and accepts 10 to 16 volts DC. It includes a battery-voltage gauge, over\/low-voltage alert, and over-temperature protection that can mute audio output during excessive heat. This makes it a flexible source unit for new marine installations or for replacing an older radio with modern streaming and multi-zone capability.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Zone Audio Control:\u003c\/strong\u003e Independently adjust listening levels for two onboard areas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP66 Front Panel:\u003c\/strong\u003e Helps protect the front control surface from water exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth 5.0 Streaming:\u003c\/strong\u003e Stream audio wirelessly from compatible Bluetooth devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Inch IPS Color Display:\u003c\/strong\u003e Delivers clear source and playback information at the helm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDedicated RCA Outputs:\u003c\/strong\u003e Supports Zone 1, Zone 2, and subwoofer amplification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB Media Playback:\u003c\/strong\u003e Plays supported music files from compatible USB drives.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe HMR 20 uses a compact rectangular marine-source-unit layout with a sealed IP66-rated front panel, physical source and zone controls, a rotary volume\/select knob, and multicolor button illumination. Hertz specifies a 3-inch color TFT IPS display for readable on-screen information. The manufacturer specifies protection performance for the front panel, but does not identify the receiver's enclosure material.\u003c\/p\u003e\u003cp\u003eInstallation requires a 122 x 52 mm (4.8 x 2.05 in) mounting opening and 99 mm (3.89 in) of mounting depth behind the panel, plus room for the harnesses and connectors. The receiver is intended for 12-volt negative-ground boats and uses a 15A fuse. Use its amplified speaker outputs for four compatible 4- to 8-ohm speakers, or use the RCA zone and subwoofer outputs when integrating external amplifiers.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631743131718,"sku":"HMR20","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61cVq_RUohL.jpg?v=1784381314","url":"https:\/\/audiowatt.store\/products\/hertz-hmr-20-marine-digital-media-receiver","provider":"Audio Watt Store","version":"1.0","type":"link"}
