The Fredenstein HD Preamp is perfect for wider bandwidth sources like acoustic instruments, voices, and drums. With an entirely new approach to mic-level amplification, and yielding a new sound quality, it overcomes the limitations of conventional preamps.
With 96 kHz/192 kHz sampling rates becoming very popular while tracking, studios are still using equipment which cannot provide the frequency response or bandwidth provided by modern A/D converters. The HD Pre overcomes these limitations especially for wider bandwidth sources such as acoustic instruments. It is the preferred choice for classical recordings and Jazz recordings as well. Besides incorporating a fully discrete signal path and a Class-A balanced output stage, the HD Pre uses a revolutionary current amplification circuit, which neutralizes limiting internal transistor capacitance. As a result, the HD Pre features an unprecedented bandwidth of over 900 kHz.
