Setup, channel tuning and status monitoring are handled in the Sonos app. It is an installed product: it must be fitted and configured by an installer.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 amplified outputs, 125 watts per channel into 8 ohms with all channels driven\u003c\/li\u003e\n  \u003cli\u003eUp to 4 zones; you choose the zone for every output, in mono or stereo\u003c\/li\u003e\n  \u003cli\u003eClass D amplification with GaN transistors and post-filter feedback (PFFB)\u003c\/li\u003e\n  \u003cli\u003eProTune: parametric equalisation over 10 bands, gain and delay on every channel\u003c\/li\u003e\n  \u003cli\u003eStereo RCA line input and USB-C input for the Sonos Line-In Adapter\u003c\/li\u003e\n  \u003cli\u003eRCA subwoofer output\u003c\/li\u003e\n  \u003cli\u003eApple AirPlay 2 and Spotify direct control\u003c\/li\u003e\n  \u003cli\u003eEthernet and Wi-Fi 6\u003c\/li\u003e\n  \u003cli\u003eFanless cooling\u003c\/li\u003e\n  \u003cli\u003eRack mounting with the 2U mount, sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eZones and speakers\u003c\/h3\u003e\n\u003cp\u003eThe eight outputs are set one by one, in mono or stereo, and shared out between zones to suit the system design, up to four zones per unit. With Sonos Architectural speakers the minimum load allowed is 2.67 ohms, and a dedicated optimisation can be switched on in the app: it recognises them and adjusts the signal processing to match. A Sonos subwoofer can be added to each zone; the RCA subwoofer output is assigned to one zone of your choice.\u003c\/p\u003e\n\u003ch3\u003eAmplification\u003c\/h3\u003e\n\u003cp\u003eThe Class D output stages use gallium nitride (GaN) transistors and feedback taken after the output filter (PFFB). Stated figures: total harmonic distortion of 0.005%, frequency response from 15 Hz to 20 kHz within ±0.5 dB, signal-to-noise ratio of 114 dB, damping factor above 400 into 8 ohms. The chassis sheds heat without a fan; idle consumption is 5.4 watts.\u003c\/p\u003e\n\u003ch3\u003eTuning with ProTune\u003c\/h3\u003e\n\u003cp\u003eProTune matches each channel to the connected speaker and to the room. It includes parametric equalisation over 10 bands: for each one you set the gain (±15 dB), the width and the frequency, with bell or shelving filters; plus channel gain from −15 to +5 dB, a delay of up to 50 milliseconds and a high-pass filter between 15 and 100 Hz.\u003c\/p\u003e\n\u003ch3\u003eSources and network\u003c\/h3\u003e\n\u003cp\u003eAmp Multi is controlled from the Sonos app and supports Apple AirPlay 2 and Spotify direct control. The stereo RCA input feeds an analogue source to one zone; the USB-C input, with the Sonos Line-In Adapter, makes it available in every zone at 44.1 kHz and 16 bit. It joins the network by Ethernet cable (100BASE-TX) or over Wi-Fi 6, on 2.4 or 5 GHz.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThe unit measures 436.8 × 64.5 × 265.2 mm (width, height, depth), weighs 5.06 kg and comes in matt black. The \u003ca href=\"\/en\/products\/sonos-amp-multi-rack-mount\"\u003e2U rack mount\u003c\/a\u003e, sold separately, leaves room above and below for airflow and brings the width to 483 mm: no vent panels are needed between units. During setup each unit identifies itself in the app with a chirp; LEDs on the front and rear show the status of the unit, of the eight outputs and of the Ethernet port. The power supply is universal, from 100 to 240 volts.\u003c\/p\u003e\n\u003ch3\u003eIncluded accessories\u003c\/h3\u003e\n\u003cp\u003eAmp Multi comes with a 2-metre power cable and eight Sonos banana plugs.
