The CDA-137EBT high-performance head unit delivers benchmark sound quality thanks to Alpine's all-new CD mechanism, world-leading circuit design amd cutting-edge audio engineering. Boasting advanced features including MediaXpander technology, digital time correction, 7-Band parametric EQ or 5-Band parametric EQ and high pass filter enable precise fine-tuning and sound customisation. Also, a Burr Brown 24-Bit DAC for ultra-high resolution processing and a 4-Volt preout stage achieve the best possible audio reproduction. Built-in Bluetooth Plus provides hands-free operation of a Bluetooth enabled mobile phone, and many other convenient functions like adjustable volume and text messaging alert, as well as audio streaming. It's also ready for automatic IMPRINT calibration with the PXA-H100 processor for the ultimate in sound clarity and imaging.
