Now you can take advantage of traditional McIntosh standards of excellence in the MC207 Power Amplifier. Seven 200 watt high current output channels will drive any high quality Loudspeaker System to its ultimate performance.

The MC207 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

SkyFi Cosmetic Notes:
• Glass Replaced (Sourced from McIntosh Parts Department).
• Light marking on back panel and one side.
• Top rear left corner has some scratching.

SkyFi Technical Notes:
• Calibrated meters so that all show the same at -20dB mark.
• All channels work and test past 225W with 2 channels driven.

This MC207 will ship in authentic McIntosh double box, the only way to safely transport these beasts.

McIntosh Performance Features Include:
• Power Output
The MC207 consists of seven Power Amplifier Channels, each capable of 200 watts into 4 ohm or 8 ohm Loudspeakers with less than 0.005% distortion.

• Patented Power Guard
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.

• Dynamic Power Manager
The MC207’s Dynamic Power Manager (DPM) circuitry allows for the connection of either 4 ohm or 8 ohm Loud- speakers, while at the same time delivering identical power output. A peak output current of 25 amperes per channel ensures that it will successfully drive high quality Loud- speakers such as McIntosh for a truly exciting sound expe- rience.

• Balanced and Unbalanced Inputs
Balanced connections guard against induced noise and al- low long cable runs without compromising sound quality.

• Patented Sentry Monitor with Thermal Protection
McIntosh Sentry Monitor power output stage protection circuits ensure the MC207 will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating.

• Power Control
The McIntosh Power Control Circuit allows for remote turn-on of the MC207 Power Amplifier from a McIntosh A/V Control Center or Preamplifier for a single or dual Zone System.

• Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MC207 are peak responding, and indicate the power output of the Front Amplifier Channels. The Meter Illumination may be switched Off at any time.

• Fiber Optic Solid State Front Panel Illumination
The Illumination of the Front Panel is accomplished by the combination of custom designed Fiber Optic Light Diffusers and Light Emitting Diodes (LEDs). This provides even Front Panel Illumination, together with the extra long life LEDs.

• Glass Front Panel and Super Mirror Chassis Finish
The famous McIntosh Illuminated Glass Front Panel and the Stainless Steel Chassis with Super Mirror Finish ensure the pristine beauty of the MC207 will be retained for many years.

Testing Process:

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.

If the amplifier passes visual inspection, we move on to a controlled power on sequence using a Sencore safety analyzer to monitor current draw in real time. Once the amplifier is determined to be safe to operate, we connect it to full AC mains for function and power testing. We connect the speaker outputs of the amplifier to a Sencore PA81 Power Analyzer which acts as a dummy load, DC offset monitor, and oscilloscope interface. We start with a low level 1KHz test signal at the amplifier’s input and slowly increase its amplitude while monitoring the output on an oscilloscope for signs of noise, clipping, distortion, or improper channel balance. We continue increasing the signal level until the amplifier reaches clipping. At this point we take an output power measurement and compare it to the spec sheet of the amplifier to verify proper performance. If the device under test has both balanced and single ended inputs they are both tested at this time. We finish off the bench evaluation with a 1KHz square wave check and a 20Hz to 20KHz sine sweep to assess the amplifier’s frequency response characteristics. This battery of tests will usually reveal if the amplifier has any issues that need further attention.

Before the device leaves the bench, we perform a listening test with actual music using a variety of preferred test tracks. Our benches are outfitted with familiar monitor speakers which help us identify inconsistencies that will not always show up on our test gear. The main things that we are listening for are hum or noise with no signal present, proper center image, clicks, pops, or any other obvious undesirable audio characteristics.

If the unit passes all of these tests it is moved to our long term testing rig where we simulate real word operating conditions for 6-8 hours. This allows us to monitor the unit for signs of thermal runaway or intermittent issues that only crop up when the unit has fully come up to temperature.
