shielded and free of ground loops. It may even be necessary to add shielding to

the DC input leads to avoid RF pickup.

POWER DISTRIBUTION

Multiple amplifiers sharing a single wall-wart power supply should be looped

through each other using the DC interconnect cables P/N20602-1. Hum and

noise performance of the units can be degraded by poor DC ground connections

between units sharing a common supply, use of the recommended rack and desk

mounting kits will assure a good ground connection between units by firmly

strapping their chassis together.

CAUTION! The outer shell of the DC interconnect cables is positive relative to

the chassis. Do not allow a DC cable plugged into a powered unit to hang loose

where it might short against the chassis or rack frame.

OPTIONS

230VAC

The WA100-2 tabletop power supply accepts 230VAC/50-60Hz via an IEC320

male 3 pin AC input connector. User supplies a matching line cord for the local

power system.

BATTERY OPERATION

Alkaline battery packs (BBU100-1) and 24VDC converters for operation from 12V

belt pack or automotive batteries (DC100-1) power modules are available.

MAINTENANCE

There is no routine maintenance required. If you have a problem, check panel

LED indicators to assure that the units have DC power, eliminate by substitution

input and output cables, connectors, downstream devices, DC interconnect

cables and Wall Wart power supplies.

POWER SUPPLY LEVELS

The recommended loaded DC input voltage range is 22VDC minimum to 32VDC

maximum over the full range of AC line voltage tolerances. The audio circuits

continue to work with reduced headroom below 22VDC. Momentary surges up to
