PURPOSE
The MX101 is a three-input miniature mono mixer designed for demanding in-
the-field use in broadcast ENG (Electronic News Gathering) and Field Production
applications. The MX101 incorporates most of the features requested by news
professionals, sports announcers, and film and video sound engineers into a tiny
and rugged package.
The MX100 and MX100C Studio Mixers are lower cost, high quality studio mixers
intended for applications which do not require the full feature complement of the
MX101 field mixer. The MX100C adds an output limiter to the basic MX100 fea-
tures.
The companion XP100 Input Expander provides an additional four switchable
microphone/line inputs and can be used with any of the mixers.
The MX101, MX100 and MX100C Mixers may be used alone or in combination
with the XP100 Expander for any application requiring a compact, rugged and
professional sounding, mixing or input selection system. Several XP100 Expand-
ers may be added for up to a 23-input system with minimal noise buildup in the
mixing network. The MX100 or MX100C alone makes an efficient stereo-to-mono
combiner, a simple voice-over PA driver with inputs for noise masking and back-
ground music, or simply a very clean and quiet mike or line input mixer.
Several power modules for field use are available including both replaceable and
rechargeable 24V battery packs, DC/DC converters for 6 to18V automotive or
belt pack battery power and plug-in 24VDC wall supplies. An optional rugged
Field Pack carry bag includes side protection plates for the mixer with quick-
change slide mounts for the battery packs.
DESCRIPTION
MX101 MONO FIELD MIXER
Three XLR INPUTS with phantom power and front panel MIC/LINE switches
drive low noise instrumentation preamplifiers. A wide range of internal DIP switch
selectable preamp gains from 60 to 0dB is provided to accommodate either high
or low output microphones and line inputs. Phantom power can be individually
DIP switch selected for each input and is automatically switched off in the Line
Input mode. Front panel switches activate individual LO-CUT FILTERS to reduce
bumps, thumps, wind noise and bass build-up.
A switched TEST TONE oscillator and a SLATE microphone easily mark takes.
An intense LED bargraph VU meter monitors the line output and is easily viewed
even in bright sunlight. A LIMIT indicator and switch shows peaks and limiter ac-
