Connecting Speakers

1. Locate and mount all speakers in accordance with the floor plan drawing for this installation.

2. Connect each speaker to the appropriate home run or speaker-to-speaker wiring scheme as shown on the wiring plan (see

Figure 11).

3. Test speaker wiring for short circuits to ground and across speaker terminals.

4. Measure the resistance of each home run wire run with an ohmmeter. Any pair indicating a value of less than 16 Ohms -

D300A, 49 Ohms - D100A and 122 Ohms - D40 must be rechecked for possible shorted wiring or speakers. Correct any

problems and retest prior to turning on amplifier.
