Figure 7 shows a horn speaker w/amplifier connected to a PABX or EKSU which provides one or more audio page ports.
Figure 7.
(A) 8 Ohm, Amplified (1-3 Watts) page port: Maximum capacity is 125 horn speakers w/amplifiers.
(B) 600 Ohm, low power page port: Maximum capacity is 10 horn speakers w/amplifiers (See System Capacity below). If a PRM-
150 preamplifier is used, then maximum capacity is 150 horn speakers w/amplifiers.
SYSTEM CAPACITY:
For applications with a typical 600 Ohm source impedance such as a telephone system audio page port, a maximum of 10 Horn
Speakers may be used. Additional Horn Speakers (up to 150 maximum) will require the PRM-150 Preamplifier for correct level and
impedance matching.
