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. Please click here for detailed specifics regarding our specialized packing process that separates us from the rest.The McIntosh C2300 and other products you use every day were certainly offered in the manual set. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice. Our test bench has reference vintage Kef speakers that we're very familiar with which quickly reveal any discrepancies. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. If there are balanced inputs available they will be also be tested.įinal testing involves pushing actual music thorough the amplifier. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. If there is an issue, it will usually be noticeable at this point.

Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. We start with a visual inspection of all internal components to make sure there are no signs of stress or aging.

McIntosh Sentry Monitor power output stage protection circuits ensure the MC252 will have a long and trouble free operating life. Patented Sentry Monitor with Thermal Protection.The patented McIntosh Power Guard Circuit prevents the amplifier from being over driven into clipping, with its harsh distorted sound that can also damage your valuable Loudspeakers. The Autoformers also provide perfect DC protection for your valuable Loudspeakers. The McIntosh designed and manufactured Output Autoformers provide an ideal match between the amplifier output stage and speaker loads of 2, 4 and 8 ohms. The two channels can be combined into a single channel with 500 watts into 1, 2, 4, 8 or 16 ohm speakers with less than 0.005% distortion. The MC252 consists of two separate power amplifier channels, each capable of 250 watts into 2, 4 or 8 ohm speakers with less than 0.005% distortion. Please check out our full video on this amplifier: Would cost you over $6k to buy a new equivalent (yet inferior) amplifier today. One of the most compact high power amps made by McIntosh, and one of the best looking in our opinion featuring 3D glass and heavy aluminum end caps.
