PLD4.2 is 229 mm (9 in) deep.
Depending on the depth of your rack, the Rear Rack Ear Support kit (FG-000031-00) 
may be required for rack mounting. Refer to

ventilation openings, and that each side has a minimum of 
2 cm clearance.

When the AC Power is on, there is a potential of having 
dangerous voltage at the output terminals on the rear of the amplifier. Use

prior to making any connections. 
The PLD amplifiers have a Universal power supply 100 – 240 VAC, 50 – 60 Hz, with an IEC
