Rack mounting The PX amplifier can be mounted in an EIA standard rack (2U size). Precautions for rack mounting This device is rated for operation at ambient temperatures ranging from 0° to 40°C. When mounting the device with other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified upper limit, resulting in impaired performance or failure. When rack mounting the device, always observe the following requirements to avoid heat buildup: • When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave more than 1U of space between the device and other equipment. Also, either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup. Multiple PX amplifiers can be mounted by stacking vertically. • To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If the rear of the rack cannot be left open, install a commercially available fan or similar ventilating option to secure sufficient airflow. If you have installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details. Setup - Rack mounting Speaker connection  Connecting to the [SPEAKERS] terminal CAUTION Make sure that the power is turned off, to avoid the danger of electrical shock.  Binding post connector • Without plugs Remove about 15 mm of insulation from the end of each speaker cable, pass the bare wire through the holes in the appropriate speaker terminals, and tighten the terminals to securely clamp the wires. Make sure that the bare wire ends do not jut out from the terminals and touch the chassis. 15 mm • Y-plugs From above, insert the Y-plugs all the way into the opening, and tighten the terminal. 0.25" (6.3 mm) ≤0.51" (12.9 mm)  speakON connector Insert the speakON cable plug (Neutrik NL4) into the connector, and turn it to the right to lock it. 2- 2+ 1+ 1- Channel A Neutrik NL4 1+ 1- 2+ 2- PX amplifier A+ A- B+ B- Channel B Neutrik NL4 PX amplifier 1+ B+ 1- B- 2+ (not connected) 2- (not connected) PX10/PX8/PX5/PX3 Reference Manual 11
