HEADPHONE AMPLIFIERS
The PM50s/PM50sOB
Personal Monitor Amplifiers
The PM50s and PM50sOB mix a
microphone signal with a line-level
stereo monitor signal to two head-
phone outputs. The microphone
signal is passed through (hard-wired
for no signal degradation) to a mixer
or pre-amplifier. They are ideal for
performers who need to monitor
their own signal, such as their vocal,
with the main mix.

HM Series
The HM Series headphone mixing system offers a great-sounding, cost
effective and flexible way to provide custom monitor mixes in recording
and live sound environments. The combination of unique functions and
signal processing add functionality and convenience to any single or
multiple-user monitoring application. The system provides each musician
with six volume controls: four monaural (for mixer channels or busses),
plus one for an overall stereo mix and one for a stereo effects return.
◆ The HM60 master unit can stand alone or
serve as a front end for HM59 and/or HM58
remotes.
◆ The remotes come with a 25' DB25 MF
cable and can be “daisy chained”around the
stage or studio as desired. The DB25 cable is
a standard 25 pin computer serial cable and
is available in several lengths.
◆ The HM60, HM59 and HM58 units are ideal
as low distortion headphone drivers for the
most critical listening situations.

functions to provide a clear and

ment.

nine-band graphic equalizer, and

sor to provide even signal dynamics.
◆ In addition to providing high current differ-
ential buffered signals, the HM60 and HM57
also provide power and ground to the HM58
and HM59 remote mixers.

nents, and come complete with a limited
