Onkyo CS-255 CD Hi-Fi Mini System Details

The CS-255 offers the stereo experience yet ensures a wide selection of media. The lightening dock connects for the iPhone 5, iPod touch (5G) and iPod nano (7G) in the top panel. You can navigate simply to albums and playlists using the system remote control. Plus, the unit plays CDs and is compatible with anything with a USB input. So, other smartphones, tablets and flash memory drives with MP3 files may be enabled via USB. For those devices that don't feature the appropriate USB connection, a 3.5mm stereo analog input is included. The FM/AM tuner has 30 memory presets for each band (60 in total). The receiver features a digital amplifier, bundled with two 15-watt speakers and the cabinets include a large cone driver, balanced-dome tweeter and non-parallel construction. The edges are rounded in design to prevent internal standing waves.
