Audac TRU425


Line Transformer Unit – 4 x 250W

SKU: 326 Kategorijos: ,


The TRU425 is a line transformer unit consisting of four toroidal line transformers allowing low-impedance power amplifiers to be used for powering large public address audio systems with constant voltage levels of 100 Volt, 70 Volt and 50 Volt.

Each line line transformer has a rated power of 250 Watt, with an input impedance selecteable between 4 Ohm and 8 Ohm.

The secundary side of the line transformer has power taps for use in 100 Volt, 70 Volt and 50 Volt constant voltage audio distribution systems.

Unlike regular line transformer units, the TRU series has an special internal decoupling network which make them suitable for use with Class-D power amplifiers.

The line transformers are housed in a solid constructed 19” rack mounting housing with a height of one single rackspace. The connections for both in and output are performed using reliable Terminal blocks.

Output power 4 x 250W
Output Power taps 100V/ 70V/ 50V
Input impedance 4 Ohm/ 8 Ohm
Frequency Response (±3 dB) 35 Hz – 20 kHz
Dimensions (W x H x D) 482 x 44 x 322 mm
Weight 11.9 kg
