BTR-19 - Waterproof 3-zone Bluetooth Controller

The BTR-19 is a three-zone Bluetooth controller built for marine, powersports, and automotive environments where independent audio control and weather resistance are non-negotiable. Powered by Qualcomm's QCC3034 chipset, it delivers 24-bit lossless audio transmission across all three zones with a 4V RMS output and up to 35 feet of wireless range. IPX7 waterproofing and large back-lit push buttons make it practical in demanding conditions.

• Qualcomm QCC3034 Bluetooth 5.0 — supports APTX-HD, APTX, APTX Low Latency, SBC, and AAC codecs for lossless, high-fidelity audio.
• 3-Zone independent volume control — adjust each zone separately with LED illumination for clear zone identification.
• 4V RMS output — drives amplifiers with a clean, high-level signal and includes a dedicated amplifier remote turn-on wire.
• IPX7 waterproof rating — rated for full submersion, suitable for marine and powersports use.
• Bluetooth and auxiliary input switching — toggle between wireless and wired sources without additional hardware.
• Back-lit controls — large push buttons for track navigation, volume, play, and pause remain visible in low-light conditions.
• 2A Mini ATC fuse included — circuit protection built into the wiring harness.
