Connecting M150 to the power outlet:

Connect the IEC send of the detachable power cord provided to the amplifier, and plug the opposite end into corresponding outlet. It is recommended that both M150’s and your preamp are plugged into the same wall outlet if possible (perhaps using a power outlet strip). This is to avoid creating a ground loop.

Amplifier Location:

The M150 is an open tube design and depends on natural convection flow patterns for proper cooling. To ensure proper cooling, the unit should be located in a position so that the airflow is not impeded. Since there are vents on the bottom of the unit, it should always rest on a firm surface to ensure adequate spacing between the resting surface and bottom of the unit. In addition, the unit should not be placed in an enclosed shelf, and should have a minimum of 6 inches of free space above it.

OPERATION OF THE AMPLIFIER

After all proper connections have been made, you are now ready to turn the M150 amplifier on. The power on/off switch is on the front of the amp. Some preamplifiers and sources can generate dangerous transients that can damage loudspeakers. To avoid letting dangerous transients reach your loudspeakers turn your system on in the following order:

1)Turn on all sources (CD, tuner, etc.) that you will be using.

2)Turn on the preamplifier.

3)Wait until preamp has stabilized.

4)Power up M150 amplifier

5)Select listening source and play music

When powering down your system turn the amplifier off first.

Note – Important! After turning off the amplifier, wait at least one minute to turn it back on. Do not turn it on then off and then on again in quick succession. Doing this will not allow the power supply to discharge between on/off cycling and may result in transient noises.
