1. The RPS9 can be operated as a free standing unit without requiring any special cooling arrangement but should not be accidentally or deliberately covered in any way Always stand the unit on a firm flat surface well away from any soft furnishings such as carpets or curtains Rack Mounting The RPS9 is designed as a 19 inch rack mount unit and will occupy 2U 3 5 inches of rack space An important consideration when rack mounting the unit is the need for natural convection of air flow over the whole unit Good ventilation below the unit in the floor or back of the rack will ensure a path for continuous air flow Other equipment in the rack which is known not to produce a significant amount of heat should be mounted below the unit Equipment which also relies on good air flow within the rack i e most power amplifiers and other power supplies should be given due consideration and some space should be provided between such units and between the RPS9 unit Forced convection by means of a fan tray may be desirable in this situation Location As with any power supply that contains a mains voltage transformer it is recommended that the RPS9 is physically separated from other equipment particularly that which carries low level audio signals to avoid any possible hum pick up For this reason the unit is provided with a long 3m output cable to enable it to be positioned away from the mixing console For the same reason when rack mounting it is2.
