PrimaLuna USA ProLogue Five manual Inputs and Controls, Rear Panel

PrimaLuna® ProLogue Five

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.
