It is possible to emphasize or reduce five frequency bands to 12dB by 5 band equalizer circuitry. By the center position of a thumb, it is completely removed from a signal circuit and a sound as it is of the input
Replacing Panel and Meter Lamps in a McIntosh MA6900 Integrated Amplifier After about five years of almost daily use a number of the panel and meter lamps on my MA6900 had burned out. The closest Mac authorized service center is about 400 miles away from where I live, and I was reluctant to incur the cost and risks of shipping a 80 pound piece

The distortion limits for the MA6900 are no more than at rated power output for all frequencies from 20Hz to 20,000Hz. Typical performance at mid frequencies is less than The true distortion readings on the MA6900 are so low, it takes special measuring techniques to make accurate readings. Page 19 All inputs, outputs, and data ports are controlled by current amplification must be as linear as possible prior to logic circuits in the MA6900.

This is the last of the real McIntosh analog integrated amps, in gorgeous condition and fully tested. Unlike modern integrated amplifiers, this unit has what we believe to be two distinct advantages. For starters, instead of digital encoders it utilizes real potentiometers to manage the volume, balance, and EQ. This is the old school way and how McIntosh built their reputation. Second, there is no DAC built into this unit. No superfluous, outdated converter, sitting there just making noise and taking up bandwidth from the power supply. The EQ is a really nice feature to get the most out of your vintage speakers. It even has a built in phono section for connecting basic turntables. Tried and true McIntosh patented Power Guard helps to keep things from going wrong and fast to your speakers due to overdriving/clipping. The glass is impeccable, and the paintwork is devoid of any scratches or dents. We'll include a remote, plus this will ship in a brand new McIntosh-made double official box guaranteeing safe transport. Standout McIntosh Features include• Power OutputThe MA6900 consists of two separate power amplifier channels, each capable of 200 watts into 2, 4 or 8 ohm speakers with less than distortion.• Electronic Input SwitchingDigital Logic integrated circuits drive Electromagnetic Switches on all six inputs and operating functions for reliable, noiseless, distortion free switching.• Power GuardBoth channels include the patented McIntosh Power Guard circuit that prevents the amplifier from being overdriven into clipping, with its harsh distorted sound that can also damage your valuable loudspeakers.• Sentry Monitor and Thermal ProtectionMcIntosh Sentry Monitor power output stage protection circuits ensure the MA6900 will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating. Patented AutoformersMcIntosh designed and manufactured Output Autoformers provide an ideal match between the amplifier output stages and speaker loads of 2, 4 and 8 ohms. The Autoformers also provide perfect DC protection for your valuable loudspeakers.• Illuminated Power MetersThe Illuminated Power Output Meters on the MA6900 are peak responding, and indicate the power output of the amplifier.

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 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. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. 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. 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 there are balanced inputs available they will be also be testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
