DESCRIPTION
The L160D speaker uses a digital amplifier of last
generation with total power to 160W.
This highly efficient amplifier provides high power with
limited weight and dimension. Thanks to the low power
dissipated, the cooling of the amplifier module does not
require a fan.
The digital preamplifier with DSP (Digital Signal
Processing) controls the audio crossover of the acoustic
components, the frequency response, the limiter, and the
phase alignment.
The correct switch on of the amplifier is guaranteed by an
initialization procedure; during this test stage the LEDs
(“LIMITER” and “ON/SIGNAL”), located on the amplifier
module, stay on together for approx. 2 sec.
At the end of the switch on procedure, on the amplifier
module, the “ON/SIGNAL” green LED flashes slowly,
when there is signal absence.
During normal operation the “ON/SIGNAL” green LED serves as Vu-meter monitoring the
audio level reproduced.
The "LIMITER" red LED lights up to indicate that the internal limiter circuit has tripped to
prevent amplifier distortion and protects the speakers against overloads.
Thermal control is provided by the internal DSP, by means of one sensor, controls the
temperature of the amplifier, avoiding overheating by limiting the overall volume.
In case of overheating (> 90°C) the volume decreases proportionally to the temperature
increase, making the change unnoticeable.
The correct volume and all the functions are automatically restored when standard
operating temperatures are reached.
The speaker is equipped with 5” woofer with dome tweeter (coaxial - voice coil 1") and 5”
woofer (voice coil 1")
COMMANDS ANDFUNCTIONS(FIG.1)
1) “ BALANCED INPUT” (XLR) and " LINK" (JACK 6,3mm) CONNECTORS
2) “INPUT SENS” SWITCH
3) EQUALIZATION “DSP SETUP” SELECTOR
4) “VOLUME” CONTROL
5) “LIMITER” INDICATOR LIGHT
6) “ON SIGNAL”INDICATOR LIGHT
These balanced inputs can be used to connect balanced or unbalanced
microphones or audio sources at line level (0dB) (eg. preamplifier, mixer, recorder,
CD player, musical instrument, ...).
The balanced connector is connected in parallel and can be used to send the audio
signal to other amplified speakers, recorders or supplementary amplifiers.
Position the switch in LINE to use a line level source (0 dB) or MIC to use a
microphone.
This control enables to select the suitable equalization for loudspeaker use.
The knob regulates the speaker´s volume.
This control does not affect the output “LINK” levels.
This indicator shows red to indicate that the internal limiter circuit has tripped.
This prevents amplifier distortion and protects the speakers against overloads.
This indicator light comes on green to indicate that the amplifier is switched on and it
is working properly. The “ON SIGNAL” green LED flashes slowly, when there is
signal absence. During normal operation the LED serves as Vu-meter monitoring
the audio level reproduced.

8) "AUX CHANNEL - VOLUME" CONTROL
9) POWER SWITCH “POWER”
10) FUSE CARRIER “FUSE”
11) POWER CABLE SOCKET “MAINS”
Through the RCA phono connectors, this input permits easy connection of CD, DAT,
cassette players, etc.... .
This control adjusts the output volume from the speaker of just the AUX CHANNEL
signal.
This control does not affect the overall volume of the speaker.
This switch can be used to switch the speaker on and off.
Mains fuse housing. Replace only with identical value!
Used for connecting the power cable supplied.
The DSP allows the selection of 8 different equalizations:
For use during live performances with the speaker placed on a stand.
Recommended for musicians and singers.
To listen and use music from MP3 players, CDs, etc.., even in a live situation with the
speaker positioned on a stand. Low and high frequencies are emphasized.
To be positioned on the floor as stage monitor. Low frequencies, emphasized by the
floor, are limited, thus preventing related feedbacks.
Designed for male voices since middle and low frequencies are emphasized
minimizing the feedback due to the proximity effect of the cardioid or hypercardioid
microphones.
Designed for female voices. This preset emphasizes middle and high frequencies,
making voices sharper. The feedback is extremely limited for both cardioid and
hypercardioid microphones.
Designed specifically for use in the studio, or where a flat response curve of the input
signal is required. In this case the output signal turns out to be as faithful as possible
to the original signal.
For all those situations where the music is played in the background. In this case the
low frequencies are extended and enhanced, so as to create a more enveloping
sound even at low sound level.
When the speaker is positioned on a stand, specifically designed for music playback
(MP3, CD etc..). The response curve of the speaker in this preset turns out to be
identical to that of the analogue model L160.
