230V AC Input

230 AC Input - IEC

A standard IEC (kettle plug) lead should be used to apply power to the unit. The fuse
holder is located just next to the mains input socket. If the fuse needs to be replaced a
315mA anti surge (slow blow) type should be used.
Mixed output – 6.3mm mono jack socket
This socket provides a mixed signal output, combining the three signals (bass, mids,
and tops) from the crossover. Use this socket to connect a tape deck or similar
recording device. If the preamp is to be used with a single amplifier then connect the
amplifier to this socket.
Treble output – 6.3mm mono jack socket
Use this socket to feed a signal to an amplifier that is connected to tweeters or similar
high frequency speakers. This socket may also be linked to the mids output (using
suitable adapters or leads) to provide a signal consisting of midrange and treble.
Mids output – 6.3mm mono jack socket
Use this socket to feed a signal to an amplifier that is connected to midrange
frequency speakers. This socket may also be linked to the treble output (using suitable
adapters or leads) to provide a signal consisting of midrange and treble.
Bass output – 6.3mm mono jack socket
Use this socket to feed a signal to an amplifier that is connected to woofers or similar
low frequency speakers. This socket may also be linked to the mids or treble output
but this usual not required in most set-ups.
Line input – 6.3mm stereo jack socket
Use this socket to connect the output of a mixer or similar device to the preamp. If a
stereo jack socket is used then the signals will be combined into a mono signal
Mic input – 6.3mm mono jack socket
Use this socket to connect a low impedance microphone to the preamp.
