NSTALLATION
Because of the number and type of vacuum tubes, the MV52 dissipates
considerable heat. 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 unobstructed. At
least four inches of clearance should be provided above the unit, and at
least three 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 MV52 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 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 MV52 IS TO BE OPERATED ONLY ON AC LINE VOLTAGE OF
108 TO 125 VOLTS.
The MV52 is optionally available wired for 100 volt, 120V, 220V or 240
volt, 50/60 Hz current.
CONNECTION
INPUT:
Connect the preamplifier to your MV52 amplifier at the RCA type
connections located on the back of the amplifier.
OUTPUT:
Terminal strips are provided for connection of your loudspeak-
ers. They will accept bare wire or spade lug connectors.
Three different taps- 4 ohm, 8 ohm, and 16 ohm are provided in addition
to the "C" or ground tap.
Matching the rated nominal impedance of your speakers with the ampli-
fier output taps will not necessarily guarantee optimum performance.
The sound with a given set of speakers will vary with the diffrent
