Installation Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the safety of the installation and should be immediately corrected.
Installation (continued) Pick Points (suspended installations) The HPR152i and HPR153i enclosures feature three load-rated pick points. The HPR122i enclosure features nine load-rated pick points. As shipped from the factory, each pick point has a bolt or plug installed to retain the air-tight design of the enclosure. Never operate the loudspeaker with the pick points open (unsealed) as it will degrade the performance of the product.
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. An AC power cord hook-and-loop tether (retention strap) is provided to minimize the risk of the power cord being inadvertently pulled from its connection at the back of the amplifier.
Input Connections Full-range models have one female XLR line-level input marked FULL RANGE LINE IN. Full-range loudspeaker’s Input (IN) and Output (OUT) Connectors Subwoofers have a second set of connectors, one for the left channel’s audio and one for the right channel’s audio. We recommend balanced connections be used. Balanced connections will reduce AC hum and interference, especially with long cable runs. Unbalanced connections may be suitable for short cables.
Output Connections Full-range models have one XLR output connector marked FULL RANGE LINE OUT. The output connector is wired in parallel with the input enabling connection of multiple enclosures in a “daisy-chain” fashion. Full-range loudspeaker’s Input (IN) and Output (OUT) Connectors Subwoofer models have two sets of output connectors, one set for the left and one set for the right audio channel.
GAIN Control The GAIN control is marked in dB of attenuation. There are 21 detents for repeatable adjustments. Turn the GAIN control clockwise to increase gain and counter clockwise to decrease gain. Gain control. The upper 14 steps are about 1 dB each and settings should normally be made within this range. When operating with the GAIN set below -15 dB, it may be possible to exceed input headroom. If this is the case, reduce the input signal strength and increase the gain of the loudspeaker amplifier.
Front LED Switch The Front LED Switch, located on the rear panel, is used to enable or disable the LED located on the front of the enclosure near the bottom of the grill. Slide the switch to the ON position to enable the front LED and slide it to the OFF position to disable the front LED. Front LED switch. Most applications merit the use of the Front LED so power status can be visually confirmed, easily and quickly.
SIGNAL Indicator LED The green SIGNAL indicator alerts the user to the presence of an input signal to the HPR loudspeaker. Normal Indication The green SIGNAL indicator illuminates when the input signal exceeds -25 dB. If No Indication LED indicators. Check Gain settings and increase gain if necessary. Check input connections and audio source for signal. If the red LIMIT LED illuminates, refer to the LIMIT indicator section, below.
Application Example #1 Application Example #1 physical diagram. 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, professional CD players, or computer-based audio signal sources.
Application Example #2 Application Example #2 physical diagram. This example shows a two-channel (stereo) setup utilizing one subwoofer and 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, professional CD players, or computer-based audio signal sources.
Application Example #3 This example shows a two-channel (stereo) setup utilizing two subwoofers and two top-boxes. Application Example #3 physical diagram. 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, professional CD players, or computer-based audio signal sources. Audio output from the mixer is connected to the subwoofer input of each channel.
Application Example #4 Application Example #4 physical diagram. This example shows a two-channel (stereo) setup utilizing two subwoofers and multiple top-boxes. This is the same as Application Example #3 except an additional top-box has been added to each channel (and more could be added). Channel 1 or Left Channel Channel 2 or Right Channel To connect to additional top-boxes, connect a cable from the last top box’s FULL RANGE LINE OUT connector to the next top-box’s FULL RANGE LINE IN connector.
Application Example #5 This example shows a two-channel (stereo) setup utilizing two HPR122i loudspeakers as floor monitors. Application Example #5 physical diagram. Channel 1 or Left Channel Channel 2 or Right Channel Audio signals for the Left and Right channels are supplied by the mixer console auxiliary buss. This allows the monitor level to be adjusted independently from the main (house) mix.
