70v Speaker Wiring Distance

All speakers with step down transform ers rated for 70v systems are connected to this output.

70v speaker wiring distance.

You need a speaker out in the parking lot a mile away. The click on calculate for the required power calculation. Use this calculator to determine how much power is required for your 70 volt amplified speaker system. There are many technical disadvantages to wiring speaker systems in series parallel but the main disadvantage is the complexity of the wiring scheme required when you are faced with a system with many speakers or an odd numbers of speakers.

Note that 24 awg wire like some bell wire or spare category 5 is only 1 db down at 900 feet. The maximum length of speaker wire for a 70v line depends on the gauge of wire u0003being used.

Find that value at the bottom of the chart. One as you can see from the chart above is distance. Both entries are numeric. In fact within a building the gauge of the wire almost doesn t matter at all.

The maximum length of speaker wire for a 70v line depends on the gauge of wire being used. Read the maximum length in feet from the feet line. Determine the combined output in watts for all speakers on a line. You design a system with a 70v string of speakers where adding up the power taps on all of the speakers totals 120 watts and the total length of the speaker string is 260 feet.

Looking at the 70 7v. Below you will find a chart with different gauges and their maximum length for use in a 70v system. To use it enter the quantity of speakers the the wattage power tap used. What is generally called a 70v line speaker wiring system is also known as a constant voltage speaker wiring system.

Other output types 25v 16 and 8 ohm. A step up output transformer in the amplifier provides the high 70v output signal. You may change either of our default entries. Follow these wiring guidelines to ensure you configure your 70v audio system properly.

Use shielded wire on all 70 volt speaker runs. A 70v output is available on bogen amplifiers and is the primary type of output for paging systems.
