Please take special note of the following precautions before operating your new amplifier:

The Plinius SA-250 Power Amplifier can be operated in bridged mode and may deliver in excess of 900 watts into 8 ohms. This amplifier is also capable of a very large peak current delivery.

The Plinius SA-250 Power Amplifier operates in Class A. It is capable of generating temperatures that could have an adverse effect on other equipment, furniture etc. DO NOT leave flammable material on the amplifier whilst running, as this could pose a serious fire risk.

The Plinius SA-250 Power Amplifier is of direct-coupled design, and offers no protection from preamplifiers that have a high DC component at their outputs.

This amplifier operates at hazardous voltage levels. of the lid or base of this amplifier be referred technician.

We recommend that any work requiring removal to a suitably qualified and experienced service

DO NOT attempt to connect any input of this amplifier to it’s own outputs.

DO NOT earth any output terminal or connect any of these terminals together without following the instructions in this manual or seeking qualified assistance.

DO NOT place this amplifier in any position where liquids or any foreign material may accidentally enter it.

DO NOT connect any voltage source, short circuit, earth/ground or appliance (other than suitable high fidelity loudspeakers) to the amplifier output terminals.

Some preamplifiers, processors, CD players’ etc. produce large switching pulses when switched on causing a loud click through the loudspeakers. For this reason, turn on all other equipment in your system before turning on your Plinius SA-250, or ensure that the amplifier is in MUTE. You will not experience this phenomenon with Plinius Preamplifiers.
