T-25 AND T-45 HIGH EFFICIENCY AUDIO POWER AMPLIFIERS
General Features & Facilities
The T-25 and T-45 are highly efficient, lightweight, rugged high power amplifiers, with many
original features developed to meet the requirements of modern professional sound
reinforcement, for both touring and fixed installations. They have been designed with audio
quality ranking equal first alongside utility and ruggedness.
The T-25 and T-45 utilise proprietary progressive switching rail output, which enables
extremely high voltage swings and peak power without compromising sonic quality. Fan
speed is automatically varied as required to keep the amplifiers within temperature limits.
Signal limiters are included to protect speakers from clipped signals. The amplifiers include
full DC and short circuit protection to ensure trouble-free service even in harsh
environments.
