100V/70V Constant Voltage System Usage
The SoundWare XL is equipped with a 60 watt transformer for use in 100V/70V Constant Voltage applications.
70 Volt | 64W | 32W | 16W | 8W | 4W | Direct 8 ohms |
100 Volt | – | 16W | 8W | 4W | 2W | Direct 8 ohms |
Adjust the tap switch on the rear of the speaker to the desired setting so it will be matched to the speaker wiring coming from the power amplifier. In conventional audio systems, set the tap switch to the Dir X position. This bypasses the transformer, sending the signal directly to the speaker crossover.
In 100V/70V Constant Voltage systems where multiple speakers are used, the speakers must be connected in parallel. Never use series connections in

This shows the “chain” type parallel speaker connection method. It is the simplest method and uses the least amount of wire. The “home run” method, where every speaker wire goes from a speaker directly to the amplifier, may also be used. However that method uses more wire and can be difficult to connect to the amplfier terminals if more than two pairs of speaker are being connected.
Note: 100V/70V Constant Voltage systems may be considered high voltage wiring by local building codes. It is the responsibility of the installer to insure that the proper wiring is used when doing the installation. Reference: National Electrical Code (NEC) Section 640.9.
