UNPACKING AND INSTALLATION

Unpacking the Momentum phonostage from the Pelican case

While the component is still in its case, please move it to a location near the place where it will

be installed. Remove all jewelry including watches, rings and belts from your person to avoid

damage to the exterior during removal and installation. We recommend that two people lift the

phonostage. Because it is machined from solid aluminum, it is much heavier than it looks.

The finish of the Momentum phonostage is extremely delicate. To avoid damaging its surface, we

suggest wearing the supplied white lifting gloves when handling to avoid abrasion, fingerprints

caused by oils from skin, etc. See Operation: Maintenance for instructions on cleaning.

Installation requirements

This component's dense metal chassis and its separate power regulator base make it much heavier

than most other phono preamps, so make sure the surface that will support it can safely hold

its weight. You can place the transformer on the floor, or anywhere it will be separated from the

phonostage by at least a couple of feet.

Adequate ventilation must be provided. There should be at least 3 inches of clearance on each

side and at the top. The top and bottom vents must not be obstructed. We recommend that the

component and its base be installed in an open equipment rack to assure proper ventilation. It

may be installed in a closed cabinet or in an equipment closet, but the cabinet or closet must be

designed with substantial ventilation at top and bottom; active ventilation (i.e., powered fans) is preferred.

Do not plug the Momentum phonostage or any other Dan D'Agostino Master Audio Systems

product into a power strip or power conditioner.

The Momentum phonostage is designed with special cone feet that screw into the bottom of the

main chassis and match up with indentations on the top of the power regulator base. The bottom of

the power regulator base has soft feet designed to isolate the main chassis assembly from vibration.

(These feet will not stain or mar the surface underneath them.) To attach the cone feet, first remove

the vinyl wrap that covers the amplifier and protects the finish. (Save the vinyl wrap in the case to

use again if you ever need to ship the phonostage.) Use two people to turn the phonostage chassis

upside down and place it on a soft but secure surface—a few towels draped over a sturdy table, for

example—and place the vinyl wrap atop the towels for extra protection. Screw the feet all the way

into the threaded holes on the bottom of the chassis. Now place the power regulator base in the

place where you want to install the phonostage. Use two people to turn the phonostage back over

again. Place it carefully atop the power regulator base, lining up the points of the cone feet with the

indentations on the top of the power supply.

If you need to return the phonostage for service

If you should need to return the Momentum phonostage for service, be sure to use the original

box and materials for shipment. Before you ship the phonostage, unplug the transformer from the

wall and let the phonostage, the power regulator base and the transformer cool down for 6 hours.

To protect the finish during shipping, rewrap all components in the vinyl covering they came in.

Make sure the components are completely cool and have not been plugged in for 6 hours before

you do this. Wrapping the phonostage when it is warm will cause the vinyl to leech into the

surface and will permanently damage the finish.
