The EVU-TK60 is a transformer kit designed for compatible EVU loudspeakers, allowing them to operate on 25V, 70.7V, or 100V distributed audio systems. It replaces the loudspeaker's standard input panel and features selectable wattage taps for adjusting output levels per speaker or zone. Tap settings include 7.5W, 15W, 30W, and 60W at 25V and 70.7V, and 15W, 30W, and 60W at 100V. With an 8-ohm secondary, the transformer maintains a frequency response of 35 Hz to 20 kHz (±2 dB) and has a low insertion loss of just 1.0 dB. It provides flexible system configuration while preserving consistent audio performance.
