NSTALLATION
Because of the number and type of vacuum tubes, the MV125 dissi-
pates 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 six 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 MV125 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 MV125 IS TO BE OPERATED ONLY ON AC LINE VOLTAGE OF
108 TO 125 VOLTS.
The MV125 is optionally available wired for 100 volt, 120V, 220V or 240
volt, 50/60 Hz current.
CONNECTION
INPUT:
Connect the preamplifier to your MV125 amplifier at the RCA
type connections located on the back of the amplifier.
OUTPUT:
Terminal strips are provided for connection of your loud-
speakers. 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 different
