INSTALLATION
Because of the number and type of vacuum tubes used, the Premier Four dissipates
considerable heat (approximately 250 watts at idle). It is essential, therefore, that
proper attention be paid to ventilation. The unit should be mounted horizontally on a
flat hard surface so that the ventilation holes in the bottom are un-obstructed. At least
eight inches of clearance should be provided above the unit, and at least four inches
on the sides. The cabinet or shelf should be open at both front and back. For more
restricted installations, cooling fans are essential.
The front panel of the Premier Four will fit in a standard 19" equipment rack and is
designed to carry the weight of the unit so that it may be rack mounted. Again, it is
important that adequate clearance be provided above the Premier Four so that
ventilation is not impeded. About eight inches of the front of the rack should be left
open above the unit.
To minimize hum pickup, keep the unit well away from the preamplifier and
turntable and route power cords away from input cables.
THE PREMIER FOUR IS TO BE OPERATED ONLY ON AC LINE VOLTAGE
OF 108 TO 125 VOLTS
(Also available wired for 100 volt or 230 volt, 50/60 Hz).
