When playing MP3 discs, the same functions exist with the exception of the fast-forward and reverse functions. The repeat function can be applied to either individual tracks (files) or to entire folders. There are three modes for accessing tracks directly: direct track access, direct folder access, and wildcard search. Direct track access steps through each individual file on the disc, and direct folder access steps through the folders. The wildcard search gives you the ability to search for a file by entering characters for the search; you can then select the file you want from the search results.
Each of the three FM and two AM bands has six presets, for a total of 30 station presets. You can enter your own custom names for the stations and set the display to show the names instead of the tuning frequency. Manual tuning can be performed in steps, or you can hold the button a bit longer to cause the tuner to automatically move to the next frequency that has signal. In addition, the tuner will automatically scan for any stations it can find and store them in FM band 3 and AM band 1. By pressing the LOC button before you run this scan, you can prevent storage of all but the strongest stations. A preset scan will play each preset in the FM bands for six seconds until it has played each preset once.
Tone controls are given for Bass and Treble, with center frequencies at 110Hz and 20kHz respectively. These controls give you about 12dB of cut or boost in 1.7dB increments (7 above zero and 7 below zero). Another function, called S-Bass, introduces a boost into a narrow frequency range centered at 65Hz with three level settings that can add as much as 15dB. Each source has a level setting that can be adjusted to match the level of the tuner. The subwoofer line output has its own level adjustment as well, with up to 20dB of gain in 5dB steps. It also has a low-pass filter with three roll-off frequencies (50Hz, 80Hz and 120Hz).
Stereo outputs for front and rear speakers are provided as powered speaker connections and as high voltage line level RCA jacks. Other wires provided include remote turn-on (for external amps), power antenna, cell phone mute, and illumination (to dim the display at night). There is also a DIN connector for interfacing with optional CD/DVD changers.
Swiss Audio's SCD2000 head unit has a good feature set and the ability to play your burned MP3 discs, and is worth checking out.
