RCF L2406-T Data Sheet

DESCRIPTION

L2406

Code. 130.00.169 (black) 130.00.177 (white)

L 2406 (/L 2406W) is a compact 3-way column loudspeaker with vertical controlled
directivity providing natural hi-fi delity sound of both speech (to improve the
intelligibility) and music.
It is the optimum choice for sound system having fi xed loudspeakers, where the critical
acoustical environment or architectural constraints require vertical acoustic dispersion
control.
L 2406 is equipped with six 5” woofers and four 1” dome tweeters. Its design with
central tweeters permits a coherent sound dispersion, minimizing lobes and keeping
a compact size for a professional loudspeaker.
The crossover has a protection circuit for the 4 dome tweeters and is designed to avoid
secondary lobe creation.
The 2 central woofers are controlled and placed differently from the other 4, in order to
get a column true cardioid polar pattern.
The wide horizontal coverage angle and the controlled vertical dispersion allow the
correct sound reproduction in a wide space, in order to limit feedbacks and improve the
sound directivity (important in halls having a long reverberation time).
The column loudspeaker has a VOICE / MUSIC selector, useful to optimise the frequency
response according to its main use.
Mounting accessories are included. These have been studied to keep the column as
close as possible to the wall and simplify its installation; tilt adjustment is easy.
L 2406 can be connected to either a 100 V (/ 70 V) constant voltage line (through a
60 W internal transformer) or an amplifi er low impedance output (max. power: 200 W
RMS).
The power setting is made through the rear panel selector.
The loudspeaker power is:
a. 60-30-15-10 W (selectable), if connected to a 100 V constant voltage line
(note: with a 70 V line, the power is halved: 30-15-7.5-5 W).
b. max. 200 W on 8 ohm load.
