Professional multi-zone amplifier with 8 x 125 W:

The Sonos Amp Multi is a powerful 8-channel streaming amplifier developed specifically for professional audio installations. With eight individual amplifier channels delivering 125 W each at 8 Ohms, it can provide music in up to four separate zones. This makes it ideal for integrated audio solutions in homes where multiple rooms require high-quality sound from a single central installation.

Flexible channel assignment allows each output to be configured individually for stereo or mono and assigned to the desired zone. This enables installers to create a solution tailored to room layouts, speaker placement and specific requirements. Each zone can play its own content, while users can easily control their music through the Sonos system.

The amplifier uses advanced Class D technology with GaN (gallium nitride) and PFFB (post-filter feedback). This combination ensures high efficiency, precise speaker control and low distortion. At the same time, heat generation is reduced, making Amp Multi particularly suitable for installations where multiple amplifier channels operate together in a compact enclosure.

Precise sound adjustment with Sonos ProTune:

Sonos ProTune provides installers with extensive options for fine-tuning the sound to suit both the speakers and the acoustic characteristics of the room. The system includes a 10-band parametric equalizer, allowing frequency, gain and Q values to be adjusted individually for each channel. In addition, level, delay and high-pass filtering can be configured to optimise audio reproduction for the specific installation.

Amp Multi also supports automatic optimisation of compatible Sonos Architectural speakers. When this feature is enabled in the Sonos app, the amplifier identifies the speakers and applies a customised DSP profile that optimises frequency response and overall system performance.

With support for speaker loads as low as 2.67 Ohms when using compatible Sonos Architectural speakers, installers gain additional flexibility when designing larger audio systems.

Flexible installation and easy integration:

The Sonos Amp Multi is designed with professional installations in mind, where reliability, efficient use of space and organised cable management are essential. Its compact enclosure features a thermally optimised design that provides efficient passive cooling without fans. This eliminates mechanical fan noise while allowing the amplifier to be discreetly positioned in equipment cabinets or living spaces.

With the separately available Sonos Amp Multi Rack Mount, the amplifier can be installed in a standard 19" rack with a height of 2U. The mounting accessory is designed to ensure proper airflow without requiring additional ventilation panels between units.

Amp Multi connects to the network via Ethernet or WiFi 6 and supports Apple AirPlay 2, Spotify Direct Control and more. Analogue RCA inputs allow external audio sources to be connected, while a dedicated subwoofer output and support for Sonos Sub provide additional options for expanding the audio system.

Installation product - contact AV-Connection for a solution:

The Sonos Amp Multi is a specialised installation product that requires professional installation and configuration. It is therefore not available for individual retail purchase and cannot be ordered directly through the webshop.
