The main unit hosts the screen and 14 buttons controlling mode, volume and so on. There’s a large blue-illuminated volume knob and volume is displayed on the screen. A USB port and memory card reader are concealed behind a cover at the bottom of the unit.
We noticed the system sometimes became unresponsive when a new iPod was put in the dock. We would choose a track, put it into the dock, and the track would pause. Pressing play on the iPod often failed; the remote control would briefly summon the play arrow on the music player, but the iPod would switch to pause again. Pressing the play button on the main unit also had no effect. We tested three iPods and this problem remained consistent, though a fourth iPod nano had no such problems. Whatever the cause, our tests suggest the system should be switched off and on again if the problem occurs – the player works fine after that.
Finally, volume. As with all compacts, if you want volume output that makes your ears bleed, you’ll need to look elsewhere. The two satellite speakers push out 4.5W each while the subwoofer offers 15W. That’s 24W, fine to fill a small room. We were pleased with the loudness and accuracy of sound playback. It delivers good quality sound for its size, but ideally the cables connecting the speakers should be over four feet long.
iLuv 7500 has some flaws – the extra power button on the subwoofer, for example. The need to control the subwoofer manually limits usability – you must figure out the best possible sound balance yourself, rather than getting full use out of the remote control. It’s an acceptable mini-system, but certain technical and usability hurdles must be overcome.
