D.W. Fearn VT-4 Vacuum Tube LC Equalizer 17

INSTALLATION

The VT-4 is carefully packed for shipment and it should survive all but the most brutal

handling. If there is any damage, keep the shipping material for use during any possible

claim for damage with the shipper.

Included in the box:

1) The VT-4 Equalizer

2) Line cord

3) This instruction manual

Mounting

The VT-4 is designed for installation in a standard 19 inch rack. It requires 5.25 inches

of vertical space, but additional spacing between it and adjacent equipment is recom-

mended for adequate cooling. Ideally, a ventilated panel at least 1 rack unit high (1.25

inches) should be installed above and below the VT-4 (and around any other heat produc-

ing equipment for that matter). Be sure the bottom vent slots are not blocked. It is essen-

tial that air can flow into the bottom and out of the top of the VT-4. Equipment that runs

cool can last for a very long time.

In tight equipment enclosures, be sure there is adequate air flow. Forced air cooling will

benefit all your equipment.

The VT-4 can also be used without a rack, placed on a table, counter, or even on the

floor. Optional rubber feet are available, when requested at the time of the order.

Moderate electrical and magnetic fields in the vicinity of the VT-4 should not cause any

degradation in noise performance, due to the well-shielded construction, but proximity to

devices with motors or large power transformers (i.e. tape machines or power amps)

should be avoided.

Although the vacuum tubes in the VT-4 are selected for minimum microphonic

response, it is a good practice to avoid mounting locations that subject the VT-4 to very

high sound or vibration levels.
