Louis, and we did a lot of constant-voltage sound system installations - 25 volt systems for educational and healthcare, 70 volt systems for. With 70 volt there are a lot of advantages over 8-ohm systems. One of the main advantages is the simplicity of the wiring as well as how easy it is to match up.

The ratings and specifications are based on sine waves, but any audio signal can be played over the system. Myths regarding these systems abound. Some are rooted in fact. Others are not. Here are some of the more common misconceptions about transformer-distributed loudspeaker systems.

Audio signals are dynamic, meaning that they are only present when something is playing over the system. Contrast this to utility power distribution systems, where a voltage is always present at the electrical outlet. The Play nothing into the system and there will be no voltage on the line, other than residual noise. Figure 1 — The system gets its name from the RMS value of a sine wave used to rate the system.

Popular rated voltages include 25V, 70V, V, and V. These systems have poor sound quality, and are only suitable for paging and elevator music. This is an undeserved reputation. If you use good quality loudspeakers and transformers, these systems can have excellent fidelity, indistinguishable from conventional systems that use 8 ohm loudspeakers. It is true that there are many poor quality 70 V systems in use, but that is due to the factors that can make any sound system sound bad — poor quality products, poor design, improper calibration, or user error.

The transformers used in these systems do indeed saturate more easily at low frequencies, resulting in potentially poor bass performance. This can be remedied by over-sizing the transformers, or by simply high passing the system filtering out the low frequencies. It is reasonable to expect good fidelity to about 80 Hz without taking special measures to extend it to a lower frequency larger transformers, direct-connected subwoofer, etc.

In fact, they can be annoying. They are not needed at all for speech systems. Music systems for most applications can still sound quite good if high passed at 80 Hz. Due to the lethal voltages present on these systems, the wiring must be in conduit. It is best to treat these circuits with the same respect you would render an electrical outlet, even though in practice the voltage and available current are far lower.

These are potentially much more dangerous than the typical 70 V system. The impedance meter is handy, but not essential. In fact, the whole reason for the way that these systems are specified is to avoid impedance ratings and impedance measurements.

The objective is to avoid overloading the amplifier too many loudspeakers, too large tap size, or both. In scenarios where you are replacing an existing amplifier, an impedance measurement can assure that the replacement amplifier is large enough for the application, meaning that the minimum impedance of the line is greater than the minimum impedance that the amplifier is rated to drive.

The voltage rating of the amplifier and the power taps on the loudspeakers assume the presence of a 70 Vrms sine wave.

High density ceiling loudspeakers do indeed exhibit significant phase interference and comb filtering. The very low impedance amplifier output drives the much higher impedance loudspeaker.
