Rack Mounting Your Parasound A 52+
With its four feet removed, the A 52+’s front panel height occupies three rack spaces: 5.25” or
133 mm. (A single standard rack space occupies 1.75” or 44.5 mm vertical height.) For mounting
in a standard 19” equipment rack, you must use the Parasound HRA 3 rack mount kit (purchased
separately). The HRA 3 kit includes four bolts and eight plastic washers with raised “shoulders.”
Slide one washer onto each mounting bolt with its raised shoulder pointing toward the panel hole.
Insert the bolt through the hole and slide the other washer on the bolt with its raised shoulder
facing the rear side of the panel. The washers will sandwich the Halo Integrated panel and the
four mounting bolts to prevent metal-to-metal contact between the A 52+ chassis, the equipment
rack, and the other components mounted in the rack.
Note: Because of its high bias Class-A/AB design this amp can get very warm, even when no
music is playing. At least 4” (or 10cm) of free space must be left above the unit. Other
heat-producing components should not be positioned directly beneath the A 52+.
Warning: Do not put the screws for the feet back into the bottom of the A 52+ without the feet.
If you insert the screws without the feet they could touch internal electrical circuitry
and cause a short circuit and damage to the amp and risk of an electrical shock.
