DESCRIPTION
The “CROMO +” and series speakers use digital power
amplifiers of last generation
These highly efficient amplifiers provide 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.
“CROMO club” multichannel
DIGIPACK .
“ ” and “READY”
“”
The CROMO 8 + bi-amped active speaker is equipped
with digital amplifier delivering 300W power.
The 2-way bi-amplified speaker is equipped with 8”
woofer (1,5” voice coil) and 1” Neodymium driver (1” voice
coil) loaded with 90°/70°x60° asymmetric horn.
The speaker is made of plastic material, and is provided
with a top handle, rubber coated , which eases
transportation.
The correct switch on of the amplifier is guaranteed by an initialization procedure; during
this test stage the LEDs ( LIMITER ), 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 READY green LED
flashes slowly, when there is signal absence.
During normal operation the "READY” green LED serves as Vu-meter monitoring the audio
level riproduced.
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.
In the bottom of the box there is a standard pole mount cup
(D36mm).
The speaker has been designed to be used also as stage
monitor (45° angled).

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.
READY
The knob regulates the speaker´s volume.
This control does not affect the output “LINK” levels.
Position the switch in LINE to use a line level source (0 dB) or MIC to use a
microphone.
This switch can be used to switch the speaker on and off.

This indicator shows red to indicate that the internal limiter circuit has tripped.
This prevents amplifier distortion and protects the speakers against overloads.

on and it is working properly. During normal operation the LED serves as Vu-meter
monitoring the audio level riproduced.

PROTECTIONS
The speakers’s components in the box are protected by 1.0mm metalsteelgrille.
Cooling
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 unno

ticeable.
The correct volume and all the functions are automatically restored when standard
operating temperatures are reached.
