INSTALLATION DETAILS Make sure that the amplifier has adequate ventilation The unit is equipped with a twin fan cooling system For this reason the airflow to the front and side panels should not be blocked Permanent Rack Mounting When high powered amplifiers are rack mounted the heat generated from each amplifier can build up inside the rack causing excessive temperatures This is especially true if there is no rear opening in the rack mount enclosure To lower the interior temperature it is necessary to improve the ventilation of the rack mount Since warm air rises to the top of the rack mount cooling will be most effective if air can be expelled from the top directly 1 When installing the amplifier in a rack observe the following points 1 1 When installing more than four P4050s make sure to leave one 1U space every four units and install a blank panel without any ventilation holes Fig 1 Do not just leave this space open or cover it with a slotted ventilation panel as warm air escaping at the front of the rack will be drawn in again by the cool 1 2 Provide an air outlet at the rear of the rack To facilitate proper cooling an air outlet at the top will allow warm air to escape naturally from the inside of the rack if required a fan may also be installed to forcibly blow out warm air In case of unforced air outflow a full lU size outlet must be provided for up to 4 amplifiers and a 2U size outlet when 5 to 8 amplifiers are installed When employing forced cooling for up to 4 amplifiers one fan with a no laod output of 0 8m3 min and a maximum hydrostatic pressure of 5mm H2O must be installed while for 5 to 8 amplifiers two such fans are required unit mm 2 Make sure that a space of at least 100 mm exists between the power amplifier s rear panel and the rear of the rack 3 Place the rack in a well ventilated location 4 When a power amplifier is mounted in a rack with Fig 2 The above illustration shows an example for poor ventilation other types of components be careful that the heat generated by the power amplifier does not affect the other components Portable Rack Mounting The amplifier intakes cool air through the front panel and exhausts warm air out the side panels When mounting amplifiers in a portable rack make sure the side panels are exposed where necessary 8
