Page 2: Operation
Do not expose the amplifier to rain or moisture during operation or storage. If the unit does come into contact with moisture, remove the AC power cord immediately and leave it in a suitably dry area to dry. Take precaution before reconnecting to a power supply. Be aware that when any equipment is taken from a cold to humid location, condensation may occur inside. Always allow time for the equipment to attain the same temperature as its environment before reconnecting to a power supply.

Please note the different layout and functions of the 'PEXA' model series rear panels. Built‐in Protection The PEXA amplifiers feature integrated electronic protection including: Soft start function to prevent wave shock at power‐on Delay function for prevention of shock at switch power‐on DC current protection Over‐electric current protection Cut‐wave protection Overheat protection Pyle 'PEXA' Series Amplifiers www.PyleAudio.com... - Page 5 Binding Post 15. securely. Please make sure to respect the speaker polarity when using binding posts. Caution: Output turn off the unit before connecting an audio signal to the binding post to avoid any damage. Voltage 16. Please make sure that your local voltage matches the voltage indicated on the unit. Selector Signal Ground lift switch is used to lift the balanced input connectors' ground/shield from the Signal Ground amplifier's ground. When the signal ground is lifted, the sound source disconnects from the 17. Lift Switch amplifier's ground preventing ground loops which can generate hum and noise. See the signal ground lift switch instructions for more detail. The power amplifier must be connected only with the attached three‐wire safety power cord with protective conductor (non‐fused earthed conductor). This amplifier is made for use with the Power mains voltage labelled on the back of the amplifier only. Check the label on the back panel of the 18. Connection 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. SENSITIVITY (*Model: PEXA8000) 19. Selector Switch Allows selection of 0.775V, 1.0V or 1.40V sensitivity. These fans secures enough cooling for your PEXA8000 amplifier. The airflow is front‐to‐rear. The Cooling Fan 20. fan speed is electronically regulated depending on the temperature of the power devices. Pyle 'PEXA' Series Amplifiers www.PyleAudio.com...
