Mounting

The VT-15 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 recommended for adequate cooling. Ideally, a ventilated panel at least 1 rack unit high (1.75 inches) should be installed above and below the VT-15 (and around any other heat producing equipment for that matter). Be sure the bottom vent slots are not blocked. It is essential that air can flow into the bottom and out of the top of the VT-15. 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 ben- efit all your equipment.

The VT-15 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-15 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-15 are selected for minimum microphonic response, it is a good practice to avoid mounting locations that subject the VT-15 to very high sound or vibration levels.

Power

The VT-2 is designed to operate from 100, 120, or 220-240 volt, 50/60 Hz power. The unit will be shipped set for the voltage specified in the order, but may be changed in the field if necessary. Switching between 120V and 220V operation is simple: a recessed switch on the rear panel can be set to either voltage. The fuse value should be changed as well: 2A SB for 100/120V operation, and 1A SB for 220V operation. (For 100V operation, a simple internal wiring change is required. Call the factory for detailed instructions). The ground pin of the power cord is internally connected to the chassis. This configuration is standard in profes- sional equipment and is required by most electrical codes. A grounding screw is provided on
