2. INTRODUCTION
The HP6E is a high-quality, powerful, flexible, and reliable six (6) channel headphone
amplifier housed in a sturdy 1RU 19” standard rack-mountable metal chassis. The
HP6E boasts a variety of improvements over the standard headphone amplifiers in-
cluding improved frequency response, additional power, digital control of input selec-
tion and a fifth mix input. Built in flash memory has also been added to allow for last
state memory recall of the input selection for each channel... perfect for saving critical
studio time. The HP6E’s flexible design allows any of the four (4) available audio input
source signals can be routed to any of the 6 Class A headphone amps provided on
the HP6E. An additional fifth stereo signal can also be mixed into each individual
headphone channel. This allows for endless application support including studio mo-
nitoring, live monitoring, in ear individual mixing, signal distribution and more.
