DESCRIPTION
The K300 speaker uses a digital amplifier of DIGIPRO ® series of next generation with
cutting edge power to 120W.
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.
The correct switch on of the amplifier is ensured by an initialization procedure; during this
test stage the LEDs ( LIMITER
"
off for approx. 2 sec.
At the end of the switch on procedure, on the amplifier module, the READY green LED
blinks slowly, in the absence of the signal.
During normal operation the "READY" green LED blinks according to the song / sound
reproduction in use.
COMMANDS AND FUNCTIONS
1)
"VOLUME" CONTROL
The knob regulates the diffuser's volume.
This control does not affect the output "LINK" levels.
2)
"LIMITER" INDICATOR LIGHT
The "LIMITER" indicator light comes on red during start (for a few seconds) and
when the internal audio limiter engages. This avoids the amplifier's distortion and
protects the loudspeakers against overloads.
3)
SENSITIVITY SWITCH
Position the switch in LINE to use a line level source (0 dB) or MIC to use a
microphone.
4 )
"READY" INDICATOR LIGHT
The " READY " indicator light comes on green to indicate that the amplifier is switched
on and it is working properly.
5)
"BALANCED INPUTS LINK" CONNECTORS
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.
6)
"STEREO CD-AUX" INPUT CONNECTORS
Through the RCA phono connectors, this input permits easy connection of CD, DAT,
cassette players, etc.... .
7)
POWER SWITCH "POWER"
This switch can be used to switch the diffuser on and off.
8)
FUSE CARRIER "FUSE"
Mains fuse housing.
9)
POWER CABLE SOCKET "MAINS"
Used for connecting the power cable supplied.
EMI CLASSIFICATION
According to the standards EN 55103 this equipment is designed and suitable to operate in
3
E3 (or lower E2, E1) Electromagnetic environments.
