CONGRATULATIONS on your decision to become the proud owner of this Plinius 9200 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 your favourite music faithfully and accurately.
DESIGN PHILOSOPHY From a distance you can see that the design of the Plinius products is more than an applied styling exercise to the front panel. We have started from the ground up to produce a casing for our electronics that is unrivalled in its physical strength and visual simplicity.

PRECAUTIONS Please take special note of the following precautions before operating your new amplifier: • The Plinius 9200 Integrated Amplifier can deliver in excess of 200 watts into 8 ohms. This amplifier is also capable of a very large peak current delivery. • The Plinius 9200 Integrated Amplifier operates in Class AB. It is capable of generating heat that could have an adverse effect on other electronic equipment, furniture, etc.
AMPLIFIER FEATURES – FRONT PANEL The front of the Plinius 9200 Integrated Amplifier incorporates all the facilities you will require on a daily basis. RECORD SOURCE VOLUME x x PHONO CD PLINIUS TUNER x TAPE 1 TAPE 2 STAN DBY FRONT PANEL LAYOUT SHOWING VOLUME KNOB, RECORD AND SOURCE SELECTORS, AND DISPLAY LED DISPLAY LED An LED on the front panel indicates that the power is on.
AMPLIFIER FEATURES – REAR PANEL This panel incorporates all 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 9200 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.
CD XLR INPUT TERMINALS Below the CD RCA inputs are an additional set of ‘line level’ XLR balanced inputs for use with source components that feature XLR balanced outputs. Balanced signals are carried via a three way cable. The XLR pin configuration used in all Plinius product is: PIN 1 to GND PIN 2 to +Signal PIN 3 to -Signal NOTE: Because of the way our XLR and balanced inputs are configured it is not possible to connect both XLR and RCA at the same time.
GROUND LIFT SWITCH This switch allows the signal ground to be disconnected from the chassis. In some installations a hum loop may exist due to duplicate ground paths from different equipment. Use this switch to remove the connection from 0V to ground thus allowing some flexibility in your particular set-up. PROCESSOR SOURCE AND RETURN These RCA connections are for use with a multi-channel sound processor.
INSTALLATION AND OPERATION PLACEMENT AND VENTILATION Your Plinius 9200 may operate at a moderately high temperature 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.
INPUT / OUTPUT CONNECTION It is important that you connect your loudspeakers (outputs) and source components (inputs) to the Plinius 9200 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 describe in detail how to connect the amplifier to your system.
to the Plinius 9200 inputs, select the line input chosen above on the receiver (eg. ‘Line 1’) and operate the receiver as normal. You will be able to set the Plinius 9200 volume control to a level that will allow the loudness of its source components to match those from the receiver. All volume control adjustment for the system should then be done via the receiver’s volume control.
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. If you experience poor stereo image and/or a lack of bass, check that the loudspeaker wiring has 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.
9200 FEATURES REMOTE CONTROL Provided with your Plinius 9200 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 on the rear face of the remote that hold the battery compartment in place. The bottom end of the remote is now free to slide down for access to the batteries.
To re-fit the fuse, insert the fuse and gently turn it as far as possible anticlockwise (to the left). Now push the fuse cap in firmly, then turn clockwise (to the right) until it comes to a stop. Release inward pressure on the cap and the fuse will be fitted securely. IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING. Note that fuse failure may indicate a severe problem. Check all speakers and speaker cables for damage/short circuit, etc.
LOUDSPEAKER SELECTION Your Plinius 9200 Integrated Amplifier is designed for use with high fidelity loudspeakers. It should not be used to operate 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.
