PrimaLuna USA ProLogue Five - Manual (Page 6)

Inputs and Controls Front Panel
The front panel of the PrimaLuna models is made from machined aluminium, finished to match the
blue metallic chassis. No controls are available from the front. The power switch is located on the left
side of the amp, just behind the front plate.
Rear Panel
Looking at the rear panel, you will note you have one set of inputs and the pair of speaker terminals.
Attach the positive (+) from your loudspeaker to the 4 or 8 ohm terminal that most closely matches the
average impedance of your loudspeakers according to their manufacturer's specifications. The
negative (-) from your loudspeaker attaches to the 0 Ohm terminal.
Experiment using the 4 or 8 Ohm positive (+) terminal to find the best match for your speakers. Do not
make any assumptions. Trust your ears.
Some preamplifiers invert the audio signal. In that case you might want to connect the positive(+)-wire
of your loudspeaker cable to the 0 Ohm terminal of the ProLogue Five, and the negative (-)-wire to the
4 or 8 Ohm terminal; do so on both channels. When in doubt, consult the preamp's manual or ask the
manufacturer of the preamp. Our ProLogue Three preamplifier is non-inverting.
