Features (continued)

the -3 position decreases the output of the tweeter relative to the woofer. The 0 position is the factory setting and generally provides the most natural response from the speaker.

The use of a 70 Volt transformer allows several HS-615 speakers to be used together by running a speaker wire from one speaker to the next in a parallel connection when using a 70 Volt amplifier (as shown in the wiring diagram below).

WARNING: Refer to the wiring diagrams and voltage selector sections to properly install a 70 Volt system.

Wiring Diagrams

CAUTION: If your amplifier isn’t capable of handling the impedance of all connected speakers, this may result in overloading the amplifier and may cause possible damage to the amplifier. Check your amplifier’s documentation for proper impedance levels.

Parallel Connection

A parallel connection exists when speakers are connected directly to an amplifier (as shown in the illustration below). Each speaker’s positive terminal is directly connected to the amplifier’s positive terminal, and each negative terminal is directly connected to the amplifier’s negative terminal. This type of connection should be made when using a 70 Volt amplifier.

In this example, each speaker is set to 70 Volt operation and is being powered by a 70 Volt amplifier. If the speakers were set to 8 Ohm operation, the total impedance (using Ohm’s Law) equals (8 x 8) ÷ (8 + 8) or 4 Ohms, which may be too low for some amplifiers. Make sure to properly select 70 Volt or 8 Ohm operation before connecting the speakers to the amplifier.
