The black Yamaha MCR-B142 Micro Component System supports a variety of audio sources. For wireless audio streaming, the system features Bluetooth 2.1 + EDR technology with support for A2DP and AVRCP protocols. The Bluetooth wireless communication range is 32.8' (10m) without interference. The MCR-B142 also features a 30-pin digital iPod/iPhone dock, a slot-in type CD player and an AM/FM radio. For wired connectivity, there is an auxiliary audio jack for listening to non-Bluetooth enabled portable audio devices including laptops, smartphones, MP3 players and more. There is also a USB port, which you can use to play WAV (PCM format only), MP3 and WMA audio files from a USB memory device or flash drive.
The MCR-142 is equipped with Yamaha's IntelliAlarm technology. IntelliAlarm wakes you up gently by increasing music from your compatible iPod or iPhone gradually over several minutes until the beep goes off. Plus, by installing the Yamaha DTA Controller App on your iPhone, iPod touch or iPad, you can adjust the settings of the alarm quickly and easily. The MCR-142 stereo sound is produced from dual 4.5" full-range drivers that generate deep bass, as well as clear midrange and high notes. The system features Yamaha's Compressed Music Enhancer as well, which restores the feeling of expansiveness and dynamic range to compressed audio files.
