Get excited with this new Tube Enhancer from Phonic. The T8300 is a new generation two-channel professional tube enhancer that excites the high frequency band as well as enhancing the low frequency sounds. The Tube Enhancer uses the high quality 12AX7s valve preamplifier, which is well known for generating warm and highly enriched sounds. In addition, the T8300 draws on the benefit of a potentiometer control to fine tune the input difference between the tube and the conventional semiconductor preamplifier, giving the user greater control and flexibility. On top of these inner strengths, the T8300´s appealing faceplate is adorned with four precision vintage VU meters. This tube enhancer not only sounds good. It looks good too.
