Cambridge Audio CXR200 Black AV Receiver w/ Bluetooth The CXR200 utilizes a Cirrus Logic DSP processor and high resolution DACs. We've chosen this route because we believe Cirrus Logic are setting the standard when it comes to AV Receiver DSP processing. Intelligent Post Processing - When it comes to post processing, our CX receivers will auto-configure their output for the best results, based on your chosen speaker setup or if you prefer, you can manually choose what post processing you want to use. The CXR200 comes with an auto-calibration microphone which measures speaker distances and optimizes volume. Unlike some rival auto calibration systems, we don't alter the tonal character of your speakers at all An excellent network streaming device, the CXR200 can play files from your NAS drive or IPnP server and can be connected via Ethernet cable or wirelessly via Wi-Fi. There's also Bluetooth aptX via an optional BT100 dongle. Front ports of the CXR offer USB, MP3, and HDMI with MHL support. The rear of the machine offers similar levels of compatibility with HDMI inputs and two HDMI outputs to give twin displays or two zones.
