power-up to prevent speaker damage if there is a high signal level at the inputs. Whether you buy them or make them, use good-quality input and speaker cables. The Most intermittent problems are caused by faulty cables. Use good-quality connectors and wire along with good soldering technique to ensure trouble-free reliability. -

5. SIGNAL LED This green LED lights when its channel produces an output signal of about 4 volts RMS or more ( 1 volt or more at the input, with 0dB attenuation), indicating that there is amplified signal present in the amplifier. It is useful in determining whether a signal is reaching and being amplified by the power amplifier. - Page 7 Precautions: 1. Bridge mono mode makers it possible to drive thousands of watts into a single speaker AC current consumption will usually be higher avoid excessive single level and made sure the wiring speaker can handle the power. 2. Do not use 2-ohm loads. Installation: Rack mounting of the amplifier is optional use four screws and washers when mounting the amplifier to the front rack rails.

SPEAKER CONNECTIONS Connect the left-side loudspeaker to the left-channel speaker terminals and the right side loudspeaker to the right-channel speaker terminals of this unit, take care to observe connect (+) and (-) polarity. If the polarity of one speaker is reversed, the speakers will be out of phase, causing a loss in bass response and unstable, irregular stereo imaging. - Page 9 Speaker TM Output: The PMA amplifier offers a choice of output connections, with two 6.3mm Phone jacks. The 6.3mm Phone jack connector is designed specially for high-power speaker connections For easier insertion, insertion 6.3mm Phone jack to break banana jack output SPEAKER CABLING: Larger wire size and shorter length minimize both loss of power and degradation of damping factor.

Non-European models only… 4. Spade lugs must have insulated barrels to prevent electric shock. Warning: To prevent electric shock, do not operate the amplifier with any of the conductor portion of the speaker wire exposed.
