Rack Mounting
■ Mounting in an EIA standard rack
If multiple high-power amp units are mounted in a rack with poor ventilation, the heat from the amps will cause the
interior of the amp to become very hot, causing the performance of the amps to be impaired. When mounting amps in
a rack, you must make provision for ventilation so that the heat can escape.
When mounting amps in a rack, please attach ventilation panels above and below the amp to allow air circulation.
When doing so, it is necessary for 35% or more of the entire surface area of a 1U size panel to be open.
Air circulation will be even better if the top surface of the rack has ventilation openings.
Ventilation panel
Yamaha provides an optional 1U-size ventilation panel VP1.
