THE audio system comprises an AM/FM radio and single-slot CD player, with no sign of a cassette player. There are 10 pre-sets available per waveband. The amplifier is hooked up to four 20-watt speakers and you can choose from three sound modes - pop, classical and spoken word. All operations are via push buttons, but we've found it's not the simplest system to divine. You'll definitely need to study the manual to understand it.
