The DOUK Audio T8PRO is a tube preamplifier featuring a 7-band equalizer. The T8PRO is therefore able to precisely control each frequency band (50Hz / 125Hz / 315Hz / 750Hz / 2KHz / 6KHz / 16KHz) for highly personalized sound reproduction. The equalization is managed by a network of resistors and NE5532 OPAs for precise and reliable sound reproduction. In addition, the T8PRO uses two 6H1N-BN tubes coupled with JRC 2068D DIP8 OPAs, offering preamplification with a warm and smooth sound. Added to this is the ability to balance the channels using a potentiometer located on the far right of the front panel. In terms of connectivity, it has all the essentials with an RCA input, a balanced XLR output, and two outputs of the same type. Accessible and powerful, this tube equalizer preamplifier will delight music lovers looking for a warm and customizable sound.
