• Installation Orientation: Horizontal placement (stable desktop or shelf, preferred)
Install the CP40 on a flat, stable desktop, shelf, or other stable surface (it is non-rack mountable, horizontal placement is preferred). The installation environment should be clean and dry, free from dust, direct sunlight, high temperature, and humidity to protect the internal electronic components. Keep the power amplifier away from heat sources such as radiators, stoves, or other high-heat equipment. Since it adopts natural cooling (no built-in fan), ensure there is no less than 10cm clearance around the amplifier to facilitate heat dissipation and prevent overheating. Do not block the amplifier’s surface vents; otherwise, overheating may occur and damage the device. Avoid installing the device near water or in areas prone to liquid splashes, as it has no splash-proof protection. Ensure the installation surface can bear the weight of the amplifier (3.8kg) to avoid falling damage; do not place heavy objects on the amplifier.
