  • Page 2 18-HPR152F WARNING! Do not use a loudspeaker support pole longer than 26” (660mm) when supported by QSC’s HPR151W or HPR181W subwoofer. 19- Do not use any HPR product oriented horizontally. Horizontal orientation can cause overheating and thermal limiting. The cooling fins on the am- plifier module must be vertically oriented in order to efficiently dissipate the heat generated by the amplifier.
  • Page 3 Introduction Congratulations and thank you for your purchase of this professional, powered loudspeaker product. To get the most from your invest- ment, we recommend you review all the information provided in this User Manual. The HPR self-powered loudspeakers provide excellent sound quality, durable construction and clean, efficient, on-board amplification. Amplifiers are matched to the drivers with active equalization and precise crossover control.

  • Page 5: Installation

    There is no pole cup provided. HPR151W: The HPR151W was designed to sit on the floor or on the stage. A pole cup on the top of the enclosure accepts 35mm loudspeaker mounting poles. Rubber feet on the enclosure’s bottom help to minimize enclosure move- ment during operation.

  • Page 6: Power Switch

    AC Mains Connect AC power to the IEC socket on the back of the amplifier by locating the IEC connector-end of the AC power cord and inserting it fully into the IEC inlet on the power amplifier module. NOTE: Turn off the AC power switch before connecting AC power.

  • Page 7: Output Connections

    HPR152F and HPR153F: Insert the male XLR input into the jack marked FULL RANGE LINE IN. Ensure the connector is fully seated. HPR151W and HPR181W: Insert the left channel’s XLR input into the left channel’s (L) FULL RANGE LINE IN connector. Insert the right channel’s XLR connector into the right channel’s (R) FULL RANGE LINE IN connector.

  • Page 8: Gain Control

    Output Connections (continued) HPR151W and HPR181W FULL RANGE LINE OUT: Use the outputs marked FULL RANGE LINE OUT (Left and/or Right) when connecting to down-stream powered loudspeakers which accept full-range audio or have their own filtering. 100 Hz LOW-CUT: Use the outputs marked 100 Hz LOW-CUT OUT (L and/or R) when connecting to downstream powered loudspeakers that have no low-frequency filtering but the low-frequency roll-off is desired.
  • Page 9 For applications where the LED may distract audience members, it is easily disabled by sliding the FRONT LED switch to the OFF position. Phase Switch (HPR151W and HPR181W) When all loudspeakers in system are properly phased, a positive polarity drive signal results in a forward excursion of all loudspeaker cones.
  • Page 10 SIGNAL Indicator LED The green SIGNAL indicator alerts the user to the presence of an input signal to the HPR loud- speaker. Normal Indication The green SIGNAL indicator illuminates when the input signal exceeds -25 dB. If No Indication Check Gain settings and increase gain if necessary. Check input connections and audio source for signal.

  • Page 11: Application Example

    Application Example #1 This example shows a two-channel (stereo) setup utilizing two top-boxes. Audio signals for the Left and Right channels are supplied by the mixer console. This signal source can be just about any variable-output level audio source, such as DJ mixers, profes- sional CD players, or computer-based audio signal sources.
