Fusion Apollo MS-SRX400 Marine Zone Stereo with AM/FM, Bluetooth, Wi-Fi, DSP and 140 Watts Peak

The Fusion Apollo MS-SRX400 is a single-zone receiver meant to extend an Apollo audio system to other parts of a boat. A typical layout starts with an MS-RA770 or MS-RA670 as the main touchscreen stereo, with one or more MS-SRX400 units added in further zones. Each can share music across the boat through PartyBus or act as its own independent source. Its built-in Class D amplifier, rated 140 watts peak, drives a pair of stereo speakers, and preamp outputs let you add amplifiers for more speakers and a subwoofer.

Wi-Fi streaming offers a higher data rate than Bluetooth for better audio quality, and Bluetooth is built in as well. Fusion DSP tunes output for the listening space, and the Fusion-Link app lets a smartphone, Garmin watch or Garmin handheld browse sources and pick tracks, and it installs software updates wirelessly. The display is a 2.7-inch color LCD.
