INTRODUCTION
Thank you for your purchase of the HR155. This unit is designed and
manufactured to monitor sound from any stereo RCA line level output or
a single balanced XLR at line level. The front panel stereo 3.5mm (1/8"
jack) input provides the final touch which makes the HR155 a valuable
tool for any sound reinforcement, recording, or install application that
needs to monitor sound from a rack mounted unit.
