C5BTW 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 C5BTW 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. Color: White.
