Versatile Transmitter and Receiver

The Monoprice 43243 Bluetooth 5 Transmitter Receiver 32ft 25hrs 50W operates as either a transmitter or a receiver to add wireless audio to any system. In transmitter mode it streams sound from a wired source to Bluetooth headphones or speakers. In receiver mode it accepts audio from a phone or tablet and sends it to a traditional amplifier. Multipoint support lets two playback devices or two source devices stay connected simultaneously.

Sustained Wireless Operation

The internal rechargeable battery provides up to 25 hours of continuous audio playback before requiring a recharge. Bluetooth 5 maintains a stable link at distances up to 32 feet (10 meters) during extended listening sessions. Supported codecs include SBC, AAC, Qualcomm aptX, aptX HD and aptX Low Latency, preserving detail and keeping audio synchronised with video over long periods.

Connection Interface Limits

Wired connectivity relies on a 3.5 mm analog jack and an optical S/PDIF port for digital signals. The optical connection enables higher-quality transmission but is restricted to stereo PCM streams. Bluetooth bandwidth and codec selection determine the maximum wireless bitrate, so high-resolution multichannel formats are not supported. The 50 watt power output rating applies to the amplifier stage when driving wired speakers directly.

Questions about this item

Does the Monoprice 43243 run hot or make any noise after 25 hours of continuous use?

The unit weighs 1.5 ounces and has no fan, so it stays silent and generates negligible heat during its full 25-hour battery cycle.

What cables or ports must my existing system already have to connect the 43243?

Your audio gear needs either a 3.5 mm analogue input/output or a Toslink optical S/PDIF port — the 43243 ships with both cable types.

Will the 43243 work with my older amplifier that only has RCA inputs?

Use the included 3.5 mm to RCA adapter cable; the 43243 outputs stereo analogue audio that any legacy amp with RCA sockets can accept.
