Connecting METIS to headphones:

The headpone jack is located on the front faceplate of the preamplifier, as shown in figure 1. The Metis headphone jack provides for a _” or 6mm headphone connector. If you have headphones with a different size connector, you can use a suitable adapter. It is normal for a small amount of sound to come out of the loudspeakers when the headphones are plugged in. This can be eliminated by turning off the power amplifier.

Connecting Metis to the power outlet:

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

Connecting Metis to a turnatable:

The phono section provided in the Metis is suitable for a wide variety of cartridges. Best results will be obtained with moving magnet (mm) and high output moving coil (mc) cartridges.The cartridge loading is is preset at 47K ohms with 150 pF of capacitance.

Preamplifier Location:

The Metis 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. In addition, the unit should have a minimum of 2 inches of free space above it.

OPERATION OF THE PREAMPLIFIER

Powering up the System:

1)After all proper connections have been made, you are now ready to turn the Metis preamplifier on. The power on/off switch is on the front of the amp. After approximately ten seconds, the high voltage supply will turn on. After an additional ten seconds, the outputs will disconnect from ground and the preamp is ready. After turning on the preamplifier, turn on the power amplifier and source material and you are ready for listening.

NOTE – This unit will not play for approximately 20 seconds after power on while the tube warm up.
