SPECO 70V Multiple Tap Transformer

The SPECO TECHNOLOGIES T7010 is a 70 volt transformer with multiple taps designed for commercial audio distribution. It suits installers who need flexible impedance matching across a distributed speaker line. The unit is new and intended for permanent installation in background music or paging systems. It provides a straightforward way to connect multiple loudspeakers to a single amplifier channel.

Capacity and headroom for 70V lines

The transformer operates on a 70 volt constant-voltage line and offers several tap positions to set the power drawn by each speaker. This allows the installer to balance volume levels across zones without exceeding the amplifier's rated output. The multiple taps give headroom for typical ceiling or horn speakers in offices, schools or retail spaces. The unit runs out of headroom when the total tapped wattage approaches the amplifier's limit.

Upgrade from single-tap or direct-drive wiring

This transformer replaces a single-tap unit or a direct low-impedance run when the installation demands different power levels per speaker. The jump is worth it when a project requires zone volume control or when the cable run is long enough to make 70V distribution more efficient than low-impedance wiring. It is not for buyers who need a built-in volume attenuator or a weather-rated enclosure.
