1. OVERVIEW________________
1.1 Introduction
Thank you for purchasing the HiZ Pre Acoustic Instrument
Tube Preamp - EQ - Active D.I. The HiZ Pre is a vacuum tube
driven active direct box with a superb equalizer to craft your
sound. The ultra high input impedance preserves the full
bandwidth and bass response of a piezo element pick up. Our
negative feedback voltage amplifier design provides a very low
noise floor and wide bandwidth to ensure accurate
reproduction of your instrument’s timbre. The buffered outputs
allow you to simultaneously drive your mixer/console and
stage amplifier without loss of signal clarity. The road ready
rugged heavy gauge steel chassis is rack mountable for your
instrument case or studio rack. This pre-amp was designed
using state of the art components to provide a clean, yet warm
tube sound. Please contact us at support@leedsproaudio.com
with your questions or comments regarding this product.
Leeds Pro Audio welcomes the comments of our customers.
We appreciate the support you have shown us through the
purchases of this product.
Please pay close attention to how you connect your HiZ Pre to
your system. Improper grounding is the most common cause
of noise problems found in studio or live sound systems. We
recommend you to read this manual to familiarize your self
with this product.
Enjoy your HiZ Pre
