Re: How do I set the bias on my M60´s?????

Its been about two years since i owned the M60 Atma-Sphere amp, but it is one of the easiest amps to bias. First place the hot (red) speaker wire on the test post. Turn on the amp in warmup mode (amber light will be on). Then after about two minutes turn on the switch for full power (red light will go on ). Next simply turn the dial for DC offset and make sure it reads zero. Then depress the toggle switch and turn the other post to set the bias at .55. Remember to remove the speaker connection from the test post and hook it up where it belongs. Now you are set to enjoy some fabulous music. After about an hour of play recheck the bias and DC offset.

If you do not undrstand this then call Ralph at Atma-Sphere and go through it step by step.
