STELLA-4 OPERATING INSTRUCTIONS

11

You can use the following tables as a guide for selecting 
cable gauges and circuit breaker ratings for the system’s 
operating voltage.

The minimum electrical service amperage required by a 
Stella-188 is the sum of the Maximum Long-Term Continu-
ous Current for all Stella-4s connected to the Stella-188. An 
additional 30% above the minimum amperage is recom-
mended to prevent peak voltage drops at the service entry.

NOTE: 

For best performance, the AC cable 

voltage drop should not exceed 10 V, or 10% 

at 115 V and 5% at 230 V. Make sure that even with 
AC voltage drops that the AC voltage always remains 
within the operating window.

Safety Issues

Pay close attention to these important electrical and safety 
issues.

The Stella-188 requires a grounded outlet.

Do not use a ground-lifting adapter or cut the AC cable 
ground pin.

Keep all liquids away from the Stella-188 to avoid haz-
ards from electrical shock.

Do not operate the unit if the power cables are frayed or 
broken.

Audio Input

Up to eight channels of balanced audio are received via the 
Stella-188’s Audio Input connector. Each of the eight audio 
channels is hard-wired to the corresponding Stella-188 
Channel Outputs, thereby allowing for easy distribution of 
discrete audio channels for Constellation installations.
