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.

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.

Troubleshooting  
Situation:  
Probable Cause:  
Solution:  
No sound from speakers  
Speaker wire not  
connected  
Make sure wire is  
connected at both the  
speaker and the amplifier  
observing proper polarity  
Speaker selector on  
amplifier is not on  
Activate proper selector  
on amplifier  
No sound from speaker  
Balance control on  
receiver or pre-amp is  
not centered  
Place balance control in  
the center  
Speaker wire not securely Check all connections at  
connected  
amplifier and speakers  
Very little bass and/or  
imaging  
Speakers are wired out  
of phase  
Check entire system  
for proper polarity and  
make adjustments as  
necessary
