TMA 250-4
The TMA 250-4/500-4 Four Channels Power Amplifier is designed for professional use and provides unparalleled
quality. It Includes soft start, signal limit, two variable-speed-low-noise fans and a LED meter display. Each channel is
equipped with independent protective circuitry against open circuit, short circuit, mismatched loads and overheat.
It includes four independent channels with separate power supply. Furthermore, every channel has also a main
LED that becomes green for power-on indicator and green for muting or protection, another red LED that shows
true amplifier clipping and a yellow one for the limit stage. The high-quality components and the carefully designed
circuits ensure excellent audio performance and an extremely linear frequency response, giving crystal-clear sound
in the high range and an up-front, full-bodied bottom end. This amplifier guarantees total reliability and a trouble-
free use even in the most demanding conditions. We believe the TMA20-4/500-4 not only look great, but provide
a perfect performance, what you get is unprecedented performance at an incredibly attractive price.
