C5BT is an affordable Bluetooth enabled monitor using the newest CSR BT 4.0 technology with aptX® support. aptX® has revolutionized the Bluetooth® Stereo listening experience by significantly reducing the bit rate without affecting audio quality or introducing latency issues. With a bit-rate of 384 kbit/s @ 16/48kHz, the aptX audio codec source material is transparently delivered over the Bluetooth link, whether it is stored uncompressed or in an alternative compression (MP3, AAC, FLAC) format. The C5BT features a 5-inch low frequency transducer and a 1-inch PEI diaphragm tweeter mounted to a specially designed waveguide to create a better off-axis response. The top panel sports the digital volume control, Bluetooth pairing button and input selector. The rear panel houses the round bass-reflex port and hosts balanced ¼” TRS, unbalanced RCA inputs, ¼” balanced TRS subwoofer output and optical toslink connection. Protection features include RF interference, output current limiting, over-temperature, turn-on/off transient and subsonic filter protection.
