Fusion MS-SRX400 Stereo

You can use the MS-SRX400 as a standalone receiver for a single zone, but its real strength lies in its ability to integrate into a larger PartyBus network. It works perfectly as a compact, independent source for a cabin or cockpit, or as an extension of a wider vessel-wide audio system.

PartyBus allows you to synchronize audio across multiple Fusion stereos on the same network. You can play the same music in every zone simultaneously or group specific zones together, all controlled wirelessly through the Fusion-Link app.

Yes, it includes a dedicated subwoofer output, allowing you to connect an external amplifier to power a sub. While the unit itself has built-in amplification for your main speakers, you will need a separate amplifier for the subwoofer.

Wi-Fi is required if you want to use the PartyBus network features or high-quality wireless streaming. If you only need basic Bluetooth playback, you can operate the unit without a Wi-Fi network, though you will lose the advanced multi-zone synchronization capabilities.

No, Class D amplifier technology is highly efficient, meaning it produces less heat and consumes significantly less power than traditional marine amplifiers. It is designed specifically to maximize battery life during extended use.

The unit is very compact, measuring roughly 4-5/16" x 2-3/4" x 7/8". You will need a mounting cutout of 2" x 3.9", making it ideal for tight spaces where a standard-sized head unit wouldn't fit.
