The ii3-ESS can be ordered with an optional 25/70V audio transformer.
The optional audio transformer allows the ii3-ESS to driver one or
more speakers attached to a 25/70V distribution line. All speakers
must have their own 25/70V transformer. This allows the ESS to be
located further away (up to 3000 feet with 18 gauge wire) from the
speaker(s) and allows an individual speaker's volume to be adjusted
using its transformer taps. When using an ESS with a 25/70V
transformer, speakers must always be wired in parallel.
Here is the layout of the taps on a typical transformer
