#MCINTOSH MC 250 SERVICE MANUAL MANUALS#
Once a year, clean the closet where you keep all your devices manuals and throw out the ones that you don't use. Proper maintenance is a necessary part of your satisfaction from McIntosh C2300.

Then you can put away the manual on a shelf and use it again only in a situation where you're not sure whether you perform maintenance of the product appropriately.
You will then acquire basic knowledge to maintain McIntosh C2300 in good operating condition to make it easily reach the intended life cycle. If you do not want to read brochures every time concerning a McIntosh C2300 or other products, it is enough to read them once only - just after buying the device. Important note - be sure to read the McIntosh C2300 at least once Get acquainted with the information concerning the manual for McIntosh C2300, which will help you to avoid troubles in the future. Many instructions, immediately after the purchase, go into the trash along with the box, which is a mistake. We know from our users’ experience that most of people do not really attach importance to these manuals. Use this table for stereo connections using the barrier strips:įor 25 volt line operation connect one of the left leads to the screw marked COM on the LEFT OUTPUT barrier strip.The McIntosh C2300 and other products you use every day were certainly offered in the manual set. Use this table to determine proper speaker connection: Close impedance matching is desirable for maximum distortion-free power. The only adverse effect on the operation of a Mclntosh amplifier when it is improperly matched is a reduction in the amount of distortion-free power available to the loudspeaker. Connect the other lead from the right loudspeaker to the screw marked with the number corresponding to the speaker impedance on the RIGHT OUTPUT barrier strip.
Connect one of the leads from the right loudspeaker to the screw marked COM on the RIGHT OUTPUT barrier strip. Connect the other lead from the left loudspeaker to the screw marked with the number corresponding to the speaker impedance on the LEFT OUTPUT barrier strip. Connect one of the leads from the left loudspeaker to the screw marked COM on the LEFT OUTPUT barrier strip. The loudspeaker impedance is usually identified on the loudspeaker itself. For distances over 50 feet between the amplifier and speaker use larger wire. For the normally short distances of under 50 feet between the amplifier and speaker, #18 wire or larger can be used. Use lamp cord, bell wire, or wire with similar type of insulation to connect the speakers to the amplifier. Speakers are connected at the barrier strips marked OUTPUT on the sloped panel of the amplifier. Simply connect each channel for the impedance desired. The INPUT switch must be in the MONO position and the OUTPUT properly connected for mono loudspeaker operation or distortion and loss of power may result.įor stereo or twin channel operation it is not necessary to use the same impedance loudspeaker on each output. The shielded cable from the program source is plugged into the right jack. The INPUT switch must be in the STEREO position and the OUTPUT properly connected to the stereo loudspeakers or distortion and loss of power may result. The shielded cable from the right output of the Mclntosh preamplifier is plugged into the right jack. The shielded cable from the left output of the Mclntosh preamplifier is plugged into the left jack.
This position permit greater air flow around the transistors and component parts thereby extending the trouble-free life of the amplifier. If the amplifier is to be installed on a vertical surface it is recommended that the autoformers be on the down side. However with adequate ventilation, the amplifier can be mounted in any position except upside down. It is recommended that the MC 250 be mounted in a normal or horizontal position. Always allow for air flow by either ventilation holes or space next to the bottom of the amplifier and a means for the warm air to escape at the top. The suggested minimum space for mounting the MC 250 is 18 inches long X 8 inches wide X 11½ inches high. The direct benefit of adequate ventilation is longer, trouble-free life. Adequate ventilation is an inexpensive and effective means of preventing insulation breakdown that results from unnecessarily high operating temperatures. It is generally found that each 10° centigrade (18° F) rise in temperature reduces the life of electrical insulation by one half. Adequate ventilation extends the troublefree life of electrical instruments.
