Turn ON each monitor’s 100 Hz LOW-CUT FILTER. This will improve vocal clarity and minimize low frequency (bass) buildup on stage. Application Example #5 physical diagram. HPR122i Mixer or Other Audio Source Channel 1 or Left Channel Channel 2 or Right Channel Application Example #5 hookup diagram. Use only high-quality balanced cables for interconnecting the audio equipment. Ensure the floor-monitors have their 100 Hz LOW-CUT FILTER switched ON to provide improved clarity in the middle- and high

Polarity can be altered by miswired input cables, interconnecting cables, mixer polarity switches set incorrectly, just to name a few likely culprits. To make matters a bit more complicated, phasing is also influenced by the position of loudspeakers with respect to one another and by their position in a given room. It is possible to have all loudspeakers polarized properly (electrically) and yet achieve better bass response by having the subwoofer reverse polarized. It is even possible to achiev

NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous” voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instr

Use only QSC’s M10 forged shoulder eye bolts. Contact QSC Technical Services department for complete information. Cooling This is a self-powered loudspeaker containing an internal power amplifier that produces heat. Allow a minimum of 6” (152mm) clearance at cabinet back for convection cooling. Keep anything that might restrict airflow away from the rear of the enclosure (i.e draperies, fabric, etc...). Do not use the HPR152i, HPR153i, HPR151i, or HPR181i oriented horizontally. Horizontal orient

NOTE: it is normal for the Br Mono indicator LED to transition slowly. •STEREO MODE (Green LED). Each channel operates independently, as usual. •PARALLEL INPUT MODE (Orange LED). The inputs of both channels are hard-switched together, but all controls and speaker connections work as usual. Do not attempt to parallel the output channels to the same load.

6. Measure the DC voltage across R147. Adjust bias trimpot R131 to reach the correct voltage shown in Table 1. 7. Next, measure the DC voltage across R247. Adjust bias trimpot R231 to reach the correct voltage shown in Table 1. 8. Turn off the amplifier and reattach the channel module assembly and heat sink to the chassis. Current limit adjustment Note: Read through these instructions before proceeding. To avoid tripping the amp’s circuit breaker, work carefully but quickly, and don’t run the am

Solder a new zener diode “piggyback”-style onto each old one. Procedure: Installing new zener diodes in an ISA 450 or ISA 500T amplifier 1. Disconnect the amplifier from AC and wait at least 10 minutes for internal voltages to bleed down. Remove the top cover. 2. Remove the four screws on the bottom of the amplifier that fasten the heat sink to the chassis. 3. Remove the three screws that attach the channel module assembly to the chassis standoffs. 4. Locate zener diodes D107 and D110 on the cha

Make sure your AC supply is appropriate for the amplifier. • 1 kHz audio sine wave generator D107 & D210: • Digital multimeter • AC current probe (e.g., BK Precision model CP-1) D207 & D110: • Trimpot adjustment tool (non-conductive) Note: The circuit boards in the ISA 750 and ISA 800T are double-sided, while those in the ISA 450 and 500T are single-sided. Therefore, to minimize disassembly, this bulletin Figure 1. Prepare the leads of the recommends two different procedures among these models:
