The Quad CD Player is normally supplied for 220/240V AC
operation. For 110/127 operation the
mains transformer can be set by the wire links on the main PCB, the mains input
power fuse must also be replaced with the correct rating., Facilities are provided for operation from
four different voltage ranges, 110V,
127V, 220V and 240V settings are suitable for most applications but for 100V
supplies (Japan) the 110V taps should be used.
