The PRE1 (PZA)

A preamplifier is a key component for experiencing true home theater surround sound and a critical element for recording music, yet few people truly understand the role a preamplifier plays. The OSD Audio Pre-1 is a unique and, yes, affordable preamplifier that performs the subtle audio tasks that transform an ordinary home theater surround sound system into a "wow, I hear every detail" experience, from a dog barking to the whizz of a helicopter's blades. 

A preamplifier offers similar benefits to those in music recording by boosting low-level output on microphones. Because microphones generally have a weak output, adding a preamp will provide a better recording signal level compared to simply connecting the microphone to a computer and standard recording equipment. However, preamps do more than add volume. Like the home theater experience, A preamp in recording can refine the subtle 'color' of the sound, adding tonal quality. Let's start with what a preamp is and then cover the attributes of the OSD Audios Preamp-1 so you can make the smartest purchasing decision.
