A SHOW Driver Unit with a built-in line transformer (like the SHOW MT-60 or MT-100) lets you connect long speaker lines without losing sound quality. Inside the unit’s protective aluminum or plastic cover, the line transformer changes the voltage of your audio signal to make it travel far distances cleanly.

The KBPC5010 is a heavy-duty single-phase bridge rectifier. It safely converts AC (Alternating Current) to DC (Direct Current). It handles up to 50A of continuous current and 1000V. It uses four internal diodes to create a full-wave rectifier circuit. This lets you use both halves of an AC wave.

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.

 

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
