Class AB Integrated Amplifier
CONGRATULATIONS on your decision to become the proud owner of this Plinius 8100 Integrated Amplifier. This manual has been prepared to help you understand the operation of your amplifier, and to provide information about its design and the variety of ways it may be used. We have designed and manufactured this amplifier to reproduce faithfully and accurately, your favourite music.

Please take special note of the following precautions before operating your new amplifier: • The Plinius 8100 Integrated Amplifier can deliver in excess of 100 watts into 8 ohms. This amplifier is also capable of a very large peak current delivery. • The Plinius 8100 Integrated Amplifier operates in Class AB. It is capable of generating heat that could have an adverse effect on other electronic equipment, furniture, etc.
The front of the Plinius 8100 Integrated Amplifier incorporates all the facilities you will require on a daily basis. RECORD SOURCE VOLUME x x CD AUX TUNER x VCR TAPE 1 TAPE 2 PLINIUS 8100 FRONT PANEL LAYOUT SHOWING VOLUME KNOB, RECORD AND SOURCE SELECTORS, DISPLAY LED’S AND MAINS SWITCH MAINS SWITCH The heavy-duty rocker switch to the left of the panel turns the Mains/Line Power to the amplifier ON or OFF. Depress the right hand side of the switch to turn the amplifier on.
RECORD SELECTOR This rotary switch allows recording of any of the six different inputs available on the back panel. Note that when recording, the source that is being listened to will not be interfered with. For example, it is possible to be listening to the CD input whilst recording from the TUNER input. Two tape decks can be connected and dubbing in either direction is possible.
This panel incorporates all the terminals for connecting the input signals from your CD player, tuner, etc, and the outputs to the loudspeakers and mains supply. Please remember that your Plinius 8100 Integrated Amplifier is a high quality electronic instrument capable of an exceptional level of performance. Be sure that you understand your system’s requirements fully before you make any connection to this amplifier.
TAPE OUTPUTS These RCA outputs are situated next to the tape RCA inputs, and are provided to interface to a pair of line level recording devices. The position of the record selector on the front panel determines from which device a recording is being made. As these tape outputs are always ‘live’, both can be used to record the chosen signal at any time. MUTE SWITCH The mute switch enables disconnection of the output, without the need to use the remote control.
PLACEMENT AND VENTILATION Your Plinius 8100 operates at a moderately high temperature, especially when being driven hard. The ideal location is upon a rigid stand, or floor mounted away from direct contact with any temperature sensitive materials or deep pile carpets. Ventilation through and around the amplifier should also be kept unimpeded, so ensure that the heat vents (slots in the lid and base) are not covered or restricted in any way.
It is important that you connect your loudspeakers (outputs) and source components (inputs) to the Plinius 8100 Integrated Amplifier correctly to ensure the amplifier is not damaged, and sounds its best with your system. Now that you have read and familiarised yourself with the connections on the back of the amplifier, as covered in the previous section, we will now describe in detail the way in which you can connect the amplifier to your system.
BI-WIRING Bi-wiring uses two pairs of loudspeaker cables for each channel loudspeaker. You will notice that the rear panel of your Plinius 8100 has two pairs of output terminals for this purpose. When using bi-wires, always connect positive (+) to positive (+) and the same for the negative (-) terminals. PHASING (OR POLARITY) It is important to achieve good stereo imaging in your listening room. By observing the wiring instructions above, each power amplifier/loudspeaker combination should be in phase.
REMOTE CONTROL Provided with your Plinius 8100 is a three function remote control. The two buttons at the top of the remote adjust the volume level, and the button below switches the amplifier in and out of mute. Two AAA batteries power the remote, and these are replaced by removing the two posi-drive screws holding the bottom plate in place. The rear panel of the remote can now be slid downwards. Replace the two batteries, taking care to refit the new ones with correct polarity.
MAINS/LINE FUSE A Mains/Line fuse is fitted within the IEC socket on the rear of the amplifier. A small drawer at the bottom of this socket may be removed (after the IEC plug is removed) by levering it out with a flat blade screwdriver. The fuse fitted should be rated at no greater than 5 amps slow blow. IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING. In the unusual event that this fuse should blow, you must first establish the cause of this failure (such as power surges, damaged mains cable, etc.
Your Plinius 8100 Integrated Amplifier is designed for use with high fidelity loudspeakers. It should not be used to operate with any other type of appliance or equipment. Choice of loudspeakers is one of personal taste, providing the chosen loudspeakers are suitable for use with your amplifier. Be certain that your loudspeakers can handle most of the rated output power of this amplifier.
