(1) dB(A) is the overall sound level, measured on the A scale.
(2) All sound data measured at nominal conditions.
The Sound Pressure data quoted is only valid where the unit is installed on a false floor and against a rear wall. If the equipment is
placed adjacent to any other vertical reflective walls, values may vary to those stated, typically increasing by 3dB for each side
added. Values stated do not include for room reverberation conditions.
