250 Watt SIP/
F. Speakers
Step 1 Connect 70V speakers across the 70V SPEAKERS terminals (pins 8 & 11).
If using 25V speakers, connect half of them across the 25V SPEAKERS terminals (pins 8 & 9), and the
Step 2 other half across the 25V SPEAKERS terminals (pins 10 & 11), so that the power load is balanced
between the two outputs.
Check the power tap of each speaker connected, and be sure the sum of all the speakers connected
does not exceed 250 Watts. For example, if there are 40 speakers, and all are wired to their 5 Watt taps,
the amplifier is driving a 200 Watt load. Since the PA-250-IP is capable of driving a 250 Watt load,
Step 3 additional speakers could be added, or some of the existing speakers could be tapped at a higher wattage
setting to play louder. If the total speaker load goes "over budget" (greater than 250 Watt load), either
remove some speakers, or use lower power taps to get down to a 250 Watt load. If more than 250 Watt
load is needed, a PP-250 can be added as shown in Installation section B.
