Electrical Connection
The Model 13310-201 Driver has a 16-ohm impedance, and if used singly, connects to the 16-ohm
amplifier output tap. If two drivers are used, connect in parallel to the 8-ohm amplifier output tap.
The Model 13310-202 Driver has an 8-ohm impedance and if used singly, connects to the 8-ohm
amplifier output. If two drivers are used, connect in series to the 16-ohm output.
The Model 13310-203 Driver has a 70.7 V transformer. Connect the transformer for the power level
desired (30 watts max.). See Figure 2.
CAUTION
Installation must be in accordance with National
Electrical Code for the appropriate hazardous area classification.
