D. Long Runs Between Amplifer and Speakers
Very long runs between the PA-2A and the speakers might require
70V transformers (Parts Express 1-800-338-0531, part # 300-040 or
equivalent).
Note: For additional information on how to minimize loss of audio in
long speaker runs, see Fax Back Document 856.
E. Connecting Multiple PA-2A's
When more than 6 ringing lines are to be monitored or additional amplifiers need to be added, install as shown below,
using the 600 OHM AUDIO OUTPUT connections.
