Description
Applications
3MU12M is a professional and compact monitor system ,
it is suitable for all the demanding monitor applications.
Adopted Neodymium compression driver integrate 3"
polymer diaphragm to assure the big power output and
00
delivery natural sound performance, the dispersion is 45 x45 .
12" Neodym ium w oofer integrate 3" voice coil and latest
improved magnet circuit&short-circuit ring to achieve the
low distortion and Max.clarity under high SPL.
Very compact design, light weight and very powerful.
Perfect protection circuit design makes sure the system
working sm oothly and safely.
MU12M produce 121dB SPL continuously and 80-16kHz
frequency response, suitable for different applications from
small to large scale, including the speech and full range
applications.
MU12M adopts the ergonomic cabinet design. Large arc
cabinet effectively reduce the collision harm, round handle
design make the carrying very balanced during t he transport.
NL4 connectors are available at the both sides to optimize
the system wiring. Cabinet is made of 15mm Russian birch
plywood with advanced environmental protection.
polyurethane-based painting. Steel grille iscoated by powder
to provide strong ultra-Weatherability.

Speaker testing method
1. Frequency response
Use Pink noise to test the speaker in the anechoic room,adjust the
level to m ake the speaker work at it s rated impedance and the power
output is 1W, then test the frequency response 1m away from t he
speaker.
2. Sensitivity
Use full range Pink noise w hich was modified by EQ curve to test the
speaker in t he anechoic room, enlarge the signal to m ake the speaker
work at it s rated im pedance and the power output is 1W, then test
the sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range Pink noise w hich was modified by EQ curve to test the
speaker in the anechoic room, enlarge the signal to make t he speaker
work at its instant pow er output level, then test the SPL 1m away
from the speaker.
4. Rated Pow er
Use the pink noise according t o IEC#268-5 to test the speaker, enlarge
the signal for continuous 100hours, the rated Power is t he pow er when
the speaker will not incur hot damage or m echanics damage.
Polyurethane-based painting.
Steel grille iscoated by pow derto
provide strong ultra-Weatherability.
