DC Power
The TB8100 12 V PA is designed to accept a nominal 12 VDC input with
negative ground. There is a minimum DC start-up threshold to prevent
damaging a battery which has little capacity left.
negative ground. There is a minimum DC start-up threshold to prevent
damaging a battery which has little capacity left.
You must connect the DC supply from the battery to the PA via a fuse or
DC-rated circuit breaker with the appropriate rating, as shown in the table
below. The DC input leads should be of a suitable gauge to ensure less than
0.2V drop at maximum load over the required length of lead.
