Ground Zero GZTA 4230X-B 4 x 230W 4-channel amplifier

Renewed for 2020, Ground Zero's Titanium collection is a refreshing splash of color in the world of amplifiers. Both black and yellow end caps are delivered with the amplifiers. If you want a flashy Yellow/Black style, install the yellow ends in place. If, on the other hand, you are looking for a more restrained look, install the black ends.

In addition to the appearance, most of the interior furniture has also been renewed. The terminals have new, even better capacitors and transistors. The sliding bias makes the sound more open even at lower volumes and reduces distortion in harsher playing.

Ground Zero Titanium amplifiers have been the most popular on the market for years. Thanks to the excellent price-quality ratio, you get good sound quality and comfortable power for a reasonable price, and above all operational reliability for years to come. 4-channel amplifier with class A/B circuit, integrated active crossover and efficient, anodized heatsink
