MQ 100L

3 WAY COLUMN SPEAKER

MAIN APPLICATIONS

• Music applications

• Audio visual applications

• Shopping malls

• Restaurants

• Pubs

• Hotels

• Office building

DESCRIPTION

MQ 100L is a 3 way column loudspeaker providing natural hi-fidelity sound of
both speech and music, suitable for sound system having fixed loudspeakers
where the environment is acoustically critical or with architectural constraints.
The wide horizontal coverage angle (180°) and the vertical dispersion (60°)
allow the correct sound reproduction in a wide space, in order to limit
feedback and improve the sound directivity which is important, for instance, in
halls having a long reverberation time.
It includes a transformer inside for the connection to (100 – 70 V) constant
voltage lines, yet it can also be set to 16 Ω (low impedance connection).
When connected to a 100 V line, its power can be selected among the
values 40 W, 20 W , 10 W or 5 W through a rotary switch (thanks to internal
transformer taps).
MQ 100L is available in white (MQ 100L-W) or black (MQ 100L-B) colour
