1. It is possible to connect two 3 piece systems to one amplifier receiver creating a 4 ohm load for each channel Speaker Placement The output from the subwoofer is primarily omnidirectional and unlocatable so placement is not critical It may be placed under a counter table or bench up against a wall in a corner or out in the middle of the room Avoid blocking the ports as all of the output is from the ports The satellite soeakers are best mounted placed up high away from obstructions or blockage such as up on a wall away from corners aimed slightly downward Peavey Electronics Corporation warrants to the original purchaser of this new Architectural Acoustics product that it is free from defects in material and workmanship If within one 1 year from date of purchase a properly installed product proves to be defective and Peavey is notified Peavey will repair or replace it at no charge Note Batteries and patch cords not covered Original purchaser means the customer for whom the product is originally installed Damage resulting from improper installation interconnection of a unit or system of another manufacturer accident or unreasonable use neglect or any other cause not arising from defects in material and workmanship is not covered by this warranty The warranty is valid only as to products purchased and installed in the United States THIS LIMITED WARRANTY IS IN LIEU OF ANY AND ALL WARRANTIES EXPRESSED OR I2. watt The nominal impedance shall be 8 ohms The continuous power handl ing shall be 50 watts maximum pro gram power of 100 watts with a minimum amplifier headroom of 3 dB The outside dimensions shall be 212 wide by 9 2 high by 127 deep The weight shall be 30 pounds The loudspeaker system shall be a Peavey Architectural Acoustics model PR 603 Stereo Subwoofer CONNECTING SATELLITE SPEAKERS TO THE PR 603 STEREO SUBWOOFER The PR 603 Stereo Subwoofer facilitates hookup of satellite speakers with its built in crossover and highpass satellite output terminals The ter minals shown as inputs are the full range inputs when the subwoofer is part of a system with satellites The terminals shown as outputs are the high pass outputs to the satellite speakers when a full range signal is fed to the subwoofer inputs Speaker Polarity The input and output terminals are color coded and marked for speaker polarity Black is or ground and red is or hot Since the position of the satellites will vary with respect to the subwoofer the polarity of the satellites may need to be reversed for proper bass output Try reversing the polarity of both satellite channels only and compare this to the initial hookup Use the connection that has the most bass Make sure that both channels are connected the same way when you are done Either both satellites connected in like polarity with the sub woofer or both s

5. atellites connected reverse polarity The Speaker Wire Wire run to the subwoofer should be a minimum of 16 gauge larger for runs over 50 feet The wire from the sub woofer to the satellites should be a minimum of 18 gauge for runs up to 50 feet For satellite runs up to 100 feet use a minimum of 16 gauge For runs over 100 feet a transformer type 70 volt system such as the PR 603T should be used Multiple Speakers The PR 603 Stereo Subwoofer is designed to be used with a pair of PR 603 605 or 606 speakers as satellites creating a 3 piece stereo speaker system The subwoofer can be used with other 8 ohm speakers as the satellites For multiple speaker hook ups additional 8 ohm speakers can be connected to one amplifier receiver When adding just two more satellites LIMITED WARRANTY connect them in the same polarity as the existing satellites to the full range signal so as not to modify the termina tion of the crossover in the subwoofer and create a hole in the bass re sponse It is possible to add a total of 6 more satellite speakers to the 3 piece system 4 satellites can be wired in series parallel per channel to equal an 8 ohm load and the group of 4 is connected to the high pass outputs just as one 8 ohm speaker would be See Speaker Polarity More than a total of 8 satellites requires the use of an additional subwoofer and generally for proper bass output one subwoofer per 2 satellites works best
6. design e Compact dimensions ease placement e Drivers are tamper proof e Bandpass technology reduces distortion e Monophonic use adds output and power handling DESCRIPTION The PR 603 Stereo Subwoofer is a two channel bandpass style enclosure with a stereo subwoofer to satellite passive crossover built in The high ef ficiency bandpass design provides low distortion bass output driver protec tion and results in a cabinet of A EMEY ARCHITECTURAL ACOBSTICSA modest dimensions This state of the art enclosure adds to the versatility and usefulness of the PR 605 speaker by extending and increasing the low frequency output of the system eas ing the burden of the satellite soeaker in the bass Efficient enough to match the original PR 600 the stereo sub woofer is designed for use with the PR 605 in small to moderate installa tions such as bars lounges arcades taverns arenas or anywhere a multi channel sound system is required The bandpass enclosure design posi tions the drivers deep within the cabinet rendering them tamper proof a definite plus in a busy environment FREQUENCY RESPONSE This measurement is useful in deter mining how accurately a given enclosure reproduces an input signal The frequency response of the PR 603 subwoofer is measured at 1 meter using a 2 82 volt swept sine input As shown in Figure 1 the selected drivers in the PR 603 subwoofer com bine to give a smooth frequency r
7. esponse from 50 Hz to 160 Hz POWER HANDLING There are many different approaches to power handling ratings the most common being EIA standard RS 426A The derived shape of this test spectrum was an attempt to simulate the spectral content of con temporary music Although it does resemble contemporary music EIA RS 426A does not contain the same levels of very low frequency material found in live music situations Very high levels of low frequency material produce distortion and ultimately device failure The presence of the low frequency material will therefore yield lower device rating than produc ed by EIA standard RS 426A Although the Peavey ratings are lower than those produced by the EIA test spectrum they are far more reliable and will have a direct correlation to real world situations 83 dB 73 dB T sonz 100Hz 200 Hz 500 Hz oe L i 1kHz 2kHz SkHz 10kHz 20 kHz Figure 1 FREQUENCY RESPONSE Sone 100Hz 200Hz S00Hz Figure LEFT i i E 1 kHz 2 kHz 5kHz 10kHz 20kHz 2 IMPEDANCE il sl RIGHT OUTPUT TO SAT ELLITES INPUT FROM AMPLIFIER LEFT il il RIGHT ARCHITECTURAL amp ENGINEERING SPECIFICATIONS The loudspeaker system shall have an operating bandwidth of 50 Hz to 160 Hz The output level shall be 87 dB when measured at a distance of one meter with an input of one
