Wiring Diagrams (continued)

Series Connection

A series connection exists when two or more speakers are connected together by one wire. Typically, the negative connection of one speaker is connected to the positive connection of the next speaker as shown in the illustration below. This type of connection is reserved for certain 8 Ohm systems ONLY, and NOT FOR 70 VOLT OPERATION. Series connections should only be done with identical speakers to avoid inconsistencies in sound quality.

In this example, each speaker has a impedance of 8 Ohms. In a series connection as shown here, the total impedance equals 8+8 or 16 Ohms. The total impedance of a series connection is the sum of each speaker’s impedance.

Voltage Selector

As previously mentioned, the HS-615 can be used in a 70 Volt system or in an 8 Ohm system. The voltage selector switch allows you to properly set the

speaker to 8 Ohm or 70 Volt operation. The wattage selector switch allows

the choice of 2, 4, 8 or 16 watt taps for 70 Volt operation. For 70 Volt operation, be sure to correctly

set the wattage selector switch so that the number of speakers multiplied by the wattage setting does not exceed the power output of the amplifier.
