You can switch the Clip Limiter circuit ON and OFF via the (11) switch on the rear panel of your LAseries. If you use full range speakers, the Clip Limiter circuit will reduce the high frequency distortion and it will also protect the high frequency drivers. However, some Users prefer to switch the Limiter OFF to get more punch from Kick Drums and other sounds in the low frequencies area. 13. Output Mode Selector Switch The stereo power amplifier presents two operating modes: - Stereo Mode In this mode, channelAand channel B operate independently (as a normal stereo amplifier).The Channel A input signal will be output from the channel A output connector,and channel B input signal will be output from the channel B output connector. - Parallel Mono Mode In this mode, channelAinput signal will be output from the output connectors of both channels. Page 4 PEXA SERIES - Bridged Mode In this mode, channel A input signal will be output from the bridge-mono output Connector. 14.Cooling Fan Window This fan secures enough cooling for your PEXA3000,PEXA5000 amplifier. 15.SPEAKONAnd BINDING POSTOutputs SPEAKON connectors are specifically designed to connect high power speakers.The correct polarity is secured automatically, they prevent shock hazard and they lock-in securely. Please make sure to respect the speaker polarity when using binding post. Caution:turn off the unit before connecting an audio signal to the binding post to avoid any electric shock! 16.Voltage Selector Please make sure that your local voltage matches the voltage indicated on the unit. 17. Signal Ground Lift Switch. Signal Ground lift switch is used to lift the balanced input connectors'ground/shield from the amplifier's ground. When the signal ground lifted, the sound source disconnects from the amplifier's ground preventing ground loops which can generate hum and noise. See the signal ground lift switch instructions for more detail. 18.Power Connection The power amplifier must be connected only with the attached three-wire safety power cord with protective conductor (nonfused earthed conductor). This amplifier is made for use with te mains voltage labelled on the back of the amplifier only. Check the label on the back panel of the amplifier for the appropriate voltage. Make sure the voltage of your mains outlet is correct.The power voltage is factory set as labelled on the back panel and cannot be change afterwards. Damage caused by connecting the amplifier to Improper AC voltage voids the warranty. 19.SENSITIVITYSelector Switch Allows selection of 0.775V, 1.0V or 1.40V sensitivity. 20.Cooling Fan This fan secures enough cooling for your PEXA8000 amplifier. The airflow is front-to-rear.The fan speed is electronically regulated depending on the temperature of the power devices. Installation guidelines *DO not use these amplifiers in damp or high humidity environments. Do not use outdoors or anywhere where liquids could fall or splash onto the amplifier. *Ensure the amp is adequately ventilated, with free airflow to the front and rear panels. Keep away from other heat sources. If the amps are mounted in a rack with other amps, ensure there is adequate cool air flow front and rear. Note that air is drawn in through the back panel, and exhausted through the front panel. *Never cover the amplifiers, as they may overheat. *PYLE PRO power amplifiers are designed to fit standard 19U racks, with a 2U height and 17 depth. We recommend the use of rear rack supports, especially if the rack is to be mobile. Use shake proof washers or thread lock adhesive to prevent mounting bolts becoming loose in transit. *Ensure that the AC power supply is correct for your amplifier. The required AC supply is stated on the rear panel next to theAC power input. *Ensure that you use the correct type of mains lead for your equipment and country. This must be free from damage and easily accessible during use. Page 5
