HPI12S User Manual Getting The Best From Your HPI12S Amplification Connections The performance of any loudspeaker depends on the amplifier delivering an adequate supply of clean power. Please ensure a suitable amplifier is selected for use in conjunction with the HPI12S and accompanying speaker system. Two NL-4 connectors are mounted in a recessed panel on the rear surface of the box. This allows the speaker box to be set flat against a wall without physical interference to the speaker connector.
HPI12S User Manual Avoid Amplifier Clipping Finding a Suitable Amplifier Bearing in mind the previously described principle of amplifier power being higher than speaker power, keep signal levels low enough so that neither the Clip or Limit Active indicators are blinking frequently or are on continuously. If they are, turn down the input signal level. The HPI12S is an 8 ohm system. A low power amplifier that is clipping will quickly damage the loudspeaker.
