Rear Panel Information
MODE SWITCH
The MC 2250 will operate in three modes, Stereo,
Mono Bridge, and Mono Parallel. The Mono modes
differ in the loads they will drive and the connection
sequence to the speaker terminals.
LEFT and RIGHT OUTPUT TERMINALS
For stereo operation, output impedances of 1, 2, 4
and 8 ohms have been provided on secure, screw
type barrier strips for each channel. For monophonic
operation proper interconnection provides 0.5, 1, 2,
4, 8, and 16 ohms from the same barrier strips. See
page 4 for connecting instructions.
INPUT JACKS
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.
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
Mclntosh, set the switch in the position nearest to
the stated output rating of the source equipment.
AC POWER
The input to the MC 2250 is 120 volts 50/60 Hz at
up to 12 amps. The primary circuit is protected by a
15 Amp Fuse.
INPUT LEVEL
The Input sensitivity of the MC 2250 is 0.75 volts or
2.5 V depending on the position of the INPUT LEVEL
switch. All Mclntosh preamplifiers have been de-
signed 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
