Rear Panel Information
LEFT and RIGHT OUTPUT
For stereo operation, output connections for im-
pedances of 2.7 to 8 ohms are provided on a secure,
screw type barrier strip. For monophonic operation
proper interconnection provides 8 ohms from the
same barrier strip.
MODE SWITCH
The MC 502 can be used for stereo or mono (single
channel) operation. The MODE switch is used to
select the method of operation desired.
AC POWER
The MC 502 is rated for 120 volts, 50/60 hertz. It
uses 0.2 amperes (20watts) when there is no signal
output and up to 4 amperes (400 watts) with both
channels delivering rated power. A 4 ampere fuse
protects the MC 502 electrically. The AC power
outlet provided for auxiliary equipment is neither
fused nor switched.
INPUT
In the stereo mode of operation both input jacks
accept signal. In the mono mode of operation only
the Right (MONO) channel input jack accepts signal
and the Left channel input jack is disconnected.
INPUT LEVEL
The input sensitivity of the MC 502 is 0.75 volts or
2.5 V depending on the position of the INPUT LEVEL
switch. With indicated voltage applied and the GAIN
control clockwise, the amplifier will deliver its rated
power. All Mclntosh preamplifiers have been design-
ed to deliver 2.5 volts output with rated input. For the
best signal to noise ratio when using Mclntosh
source equipment, place the INPUT LEVEL switch in
the 2.5 V position and the front panel LEFT and
RIGHT/MONO GAIN controls in the fully clockwise
position. If more gain is desired the 0.75 V position
may be used. For source equipment other than Mcln-
tosh set the switch in the position nearest to the
stated output rating of the source equipment.
