Setup and Use
All speaker wiring connections should be made by qualified personnel and with the amplifier power removed. The 100V output
requires Class 3 wiring. Please refer to a qualified electrician or other qualified person according to local codes.
Installation
Each unit requires a space of 1.75 inch (44mm) high, 8.7 inch (221mm) wide with 10.47 inch (266mm)
depth and may be mounted on a flat surface or in a rack enclosure.
Install the unit away from heat sources, such as vents and radiators, and in rooms with adequate
ventilation. Ensure that air can circulate freely behind, beside, and above the unit where possible. Do not
exceed the ambient operating temperature of 104° F (42°C). Be aware of conditions in an enclosed rack
that may cause the temperature to exceed ambient room conditions.
Rack Mounting
The unit ships with one 1.75 inch (44mm) high and 19 inch (483mm) wide rack mount panel. This is
designed to connect up to two A460H amplifiers. The rack mount kit includes eight screws, four nuts and
a faceplate.
Rack mounting the amplifiers is achieved by aligning the supplied rack panel faceplate holes with the
corresponding holes in the front of the amplifier and screwing them together.
If only one amplifier is used, then the additional four supplied screws and nuts may be used to 'blank off'
the four remaining open holes in the rack panel.
Mounting the faceplate using screws with washers (not supplied) will prevent marring of the front panel.
Custom mounting
Mounting holes that fit four #4 sheet metal screws (not supplied) are available on the top cover of the
amplifier.
Any screws used must not exceed ¼ inch (6mm) depth into the top of the A460H enclosure
