SP-100V Pair 100v Line Transformers
For applications where more than two pairs of speakers are required installers use “100v line” amplifiers (70v in America) which are specially designed to power many loudspeakers – for example in retail environments or train stations.
<b>100v Line Signal</b>
To achieve distribution to many speakers daisy-chained over a long distance the 100v line amplifier outputs very strong “100 volt” signal. Loudspeakers for this type of amplifier need to be equipped with step-down transformers which convert this high-voltage signal to useable “speaker-level” signal.
<b>Normal Options</b>
Commonly loudspeaker manufacturers offer two versions of the same product: “low impedance” for use with normal amplifiers, and “100v line” with a 100v transformer built in for use in 100v line systems. Often the part number will end with a “t” to denote transformer. Normally the internal transformer cannot be bypassed if you need to want to use these loudspeakers with a low impedance amplifier.
<b>Vision Offers Flexibility</b>
Vision’s loudspeaker and amplifiers are all “low-impedance” because of the superior sound quality and greater power output. Instead of restricting installers to one or the other Vision offers the unique add-on SP-100V transformers which simply “retrofit” to any low impedance speakers. The SP-100V inserts between the 100v amplifier and the low impedance loudspeaker allowing any low-impedance loudspeakers need to be used with a 100v line amplifier.
