70V 100V 3W 8ohm Audio Transformer

70V 100V 3W 8ohm Audio Transformer

70-volt speakers have a built-in transformer that allows you to adjust their wattage. This dial is called a speaker "tap." You can set the tap to determine how loud the speaker can go. The higher the tap, the louder it can get; the lower the tap, the softer the volume will be.

Tap settings are critical when determining how much amplifier power you need for your speakers. When setting 70V speaker taps, the total sum of your speaker's combined wattage should be, at most, 80% of your amplifier's total available wattage output, leaving 20% headroom of buffer space. The purpose of headroom is to allow the amplifier to create the wattage needed to power all the speakers while accounting for variations in signal and protecting your equipment.
