All-Weather Bluetooth Audio Receiver

The AudioControl ACX-BT1 adds Bluetooth 4.1 connectivity to any amplifier or processor using dual RCA outputs. It streams 24-bit audio at 48 kHz with aptX HD support for low-latency playback. An IPX5-rated enclosure protects the circuitry from water jets in marine and motorsport installations. A built-in 2 A fuse and remote turn-on output simplify wiring for installers.

Ideal for Open-Air Vehicles and Marine Builds

This receiver suits side-by-sides, jet skis and boats where a traditional head unit is impractical. The remote turn-on triggers downstream amplifiers only while audio plays over Bluetooth. Buyers needing integrated source switching, volume control or multi-zone management should look at a full marine head unit instead.

Bluetooth 4.1 with aptX HD Streaming

The single specification that decides fit is Bluetooth 4.1 with aptX HD, delivering a typical 1.6 Mbps data rate and 95 dB signal-to-noise ratio. This combination determines whether your source device can transmit the high-definition stream the ACX-BT1 is built to receive.

Questions about this item

Should I add this Bluetooth 4.1 receiver or a wired line-level source to my amplifier?

The ACX-BT1 adds wireless aptX HD streaming with a 1.5 Vrms RCA output that matches typical line-level inputs, while a wired source removes the 10 metre range limit but requires a physical cable run.

What does the 24-bit 48 kHz aptX HD figure mean for daily listening?

It means compatible phones stream at 24-bit 48 kHz over Bluetooth 4.1, giving lower noise and a 95 dB signal-to-noise ratio at the RCA outputs instead of standard SBC quality.

How does the Bluetooth 4.1 connection limit real-world data rate and range?

The link tops out at 3 Mbps with a typical 1.6 Mbps throughput and works reliably beyond 10 metres line-of-sight, though obstacles and interference will reduce that distance.
