This input is for use specifically with home theatre processors. In some circumstances you may wish to use the power amplifier and speakers that the M8 is connected to as the front two channels of a surround or home theatre environment. The processor input can be used for this purpose, as any signal connected to the processor inputs can be sent directly to the power amplifier bypassing the M8 entirely.

Ventilation through and around your Plinius M8 Preamplifier should be kept unimpeded, so ensure that the heat vents (slots in the lid and base) are not covered or restricted in any way.

The Plinius M8 design incorporates a very high level of mechanical de-coupling of the input and output. However, it can still be influenced by acoustical feedback in the operating environment. The use of acoustic cones or a suitably spiked preamplifier stand or table, may further enhance the performance of this preamplifier. Consult your PLINIUS

It is important that you connect your power amplifier/s (outputs) and source components (inputs) to your Plinius M8 Preamplifier correctly to ensure the preamplifier is not damaged, and sounds its best within your system. Now that you have read and familiarised yourself with the various connections on the preamplifier, as covered in previous sections, we will describe in detail how to connect the preamplifier to your system.

Connect your CD player, tuner, tape deck, etc, to the CD, Line1, Line 2, Line 3 or Line 4 RCA inputs on the back of the Plinius M8. Make sure you connect the red coded cable to the red RIGHT RCA input, and the black (or white) cable to the black LEFT RCA input. Also make sure the RCA connectors are a snug fit and are inserted all the way in. If you are using balanced XLR cables note that only the CD input caters for this type of connection. You will also need to use the settings menu and set the CD input to balanced (see Settings Menu Structure following).

Next, connect your power amplifier/s cables to the output sockets. Ensure that you observe polarity on all cables (red is right, black is left) to ensure correct channel phasing.

It is important to achieve good stereo imaging in your listening room. By observing the wiring instructions above, each preamplifier/power amplifier/loudspeaker combination should be in phase. If you experience poor stereo image and/or a lack of bass, check that all interconnection cables and loudspeaker wires have been connected correctly. We recommend that you use one of the easily obtainable ‘test discs’ to help you ensure both phasing and channel orientation are correct. If in doubt, consult your PLINIUS

Naturally it is also important to make sure all the leads carrying signals for the RIGHT channel loudspeaker are connected to the RIGHT input to the amplifier from your preamplifier or CD player etc. Signals for the LEFT channel should be wired in a similar fashion.

Now that your Plinius M8 Preamplifier is configured to your system correctly, the mains cable can be plugged into the IEC socket on the back of the preamplifier. Re-check all interconnection cables are fitted correctly. Turn on the power switch on the rear panel. The vacuum fluorescent display will now display the messages ‘PLINIUS’, ‘M8’, ‘SERIAL NO XXXX’, while the internal circuitry stabilises. The preamplifier will then close the mute circuit and set the active input to CD.

By connecting two of the channel outputs of a home theatre processor to the M8 processor input terminals, the M8 becomes a straight-through path for any signal that is connected to it. This enables the M8 to remain in circuit for use with two channel sources (such as CD players and tuners), as well as a link to the power amp and speakers should you wish to use your normal stereo set-up in a surround or home theatre environment.

To access the processor input, press the Processor button on the remote control. To deselect the processor input and return to using CD, Line 1, etc. as a source, press the source button you wish to listen to. Note that when processor is selected, no other buttons or menu settings can be accessed, except standby and display.

You will find that the Plinius M8 will become noticeably ‘purer’ in sound after being on for a period of time. We usually recommend waiting at least 24 hours before expecting the best quality of sound reproduction from your preamplifier. Also, as the Plinius M8 uses very little power while on, we suggest leaving the unit turned on (but in standby mode while not being used) so that it will always be at it’s sonic best.
