The TOA TU-652 is a 50W driver unit. The “M” variant (TU-652M) includes a line matching transformer. The transformer steps down the high amplifier voltage (70V/100V) to a low voltage so the speaker can play sound.
Â
What is the Transformer Doing?
- High Voltage to Low:It lowers high transmission voltages down to safe levels for the driver’s voice coil.
- Loss Prevention:It prevents voltage drops over very long cable runs, such as wiring speakers on top of a tall mosque or a large factory.
Physical Details of the Transformer
- Location:It is housed inside the sealed, weather-proof rear ABS resin cover of the driver unit.
- Weight:Adds roughly 1.1 kg to 1.3 kg depending on the specific transformer installed (like the TM-30T or TM-60T).
- Tappings:It has an impedance selector switch. This allows you to choose exactly how much wattage the speaker will pull from the amplifier.
Typical Settings (for a 100V line)
- 200 Ω:Delivers 50 W of power
- 330 Ω:Delivers 30 W of power
- 670 Ω:Delivers 15 W of power
