The VTP-100 design from EDAX Audio Labs yields a preamplifer that offers a huge (+33dBu) dynamic range. It's ruler-flat frequency response and extreme low noise makes it it the ideal preamplifier for such demanding applications as the live recording of classic music amongst others. Thanks to its sophisticated discrete state-of-the-art input, transformerless output design and Class-A vacuum tube technology, the VTP-100 offers pristine sound, ultra low noise, super low distortion, excellent signal to noise ratio and a perfectly linear frequency response. The discrete input an output design's provides superior sound perfomance to that of the mic preamps (with input transformers) used in professional audio mixers.
