GENERAL INFORMATION
Thank you for having chosen a PROEL product.
FLASH15HDA
is an ac ve full-range 2-way system featuring high-grade CELESTION transducers and a DSP-controlled
lightweight ampli
fi
er module in a sturdy polypropylene cabinet. The transducers employed include a 1” compression
driver with a 1.75" voice coil on a wide constant coverage horn, designed for providing an extended response and low
distor on levels, and a high-power 15” woofer with a 3” voice coil.
The pro
fi
le of the cabinet allows the use of the enclosure also as a stage monitor, whereas four M10 suspension points
are provided for installa on in a variety of posi ons using the op onal accessories available. Two convenient aluminium
handles, plus a third on top of the cabinet, make for easy handling and transporta on.
The ampli
fi
er module includes a 100 W CLASS AB ampli
fi
er for the HF sec on and a 500 W CLASS D ampli
fi
er with SMPS
for the LF sec on. A built-in DSP sec on features state-of-the-art signal processing with 40 bit
fl
oa ng point resolu on
and 24 bit AD/DA converters, for a superior sonic performance. Advanced func ons include full parametric EQ for the
system
fi
ne tuning, delay lines for speaker alignment, up to 48 dB/oct. crossover
fi
lters, three bands of dynamic EQ,
compressors/limiters for protec ng the transducers against distor on and power overloads. 4 di
ff
erent PRESETS (FLAT,
DJ, SPEECH, MONITOR) op mized for using the system in di
ff
erent applica ons are also available.
INPUT AND CONTROL INSTRUCTIONS (FIG. 1 / 2 / 3)
1. LINE/MIC IN (combo XLR-JACK input)
This is a female combo connector, which accepts a XLR or a JACK plug from almost any type of equipment with a
balanced or unbalanced outputs. The XLR input is wired as follows:
Pin 1 = shield or ground
Pin 2 = + posi ve or "hot"
Pin 3 = - nega ve or "cold"
The JACK input is wired as follows:
Tip = + posi ve or "hot"
Ring = - nega ve or "cold"
Sleeve = shield or ground
When connec ng an unbalanced signal, wire them as follows:
Pin2 / Tip = + posi ve or "hot"
Pin 1-3 / Sleeve = shield or ground
NOTE:
whenever possible, use always balanced cables. Unbalanced lines may also be used but may result in noise over
long cable runs. In any case, avoid using a balanced cable for one channel and an unbalanced one for the other.
2. LINK (XLR output)
This is a male XLR connector, it is connected in parallel with the respec ve LINE IN input, so the LINK is wired as LINE IN
input. Connect these to the inputs of other powered speakers to make an array.
3. GND LIFT switch
This switch li the ground of the balanced audio inputs from the earth-ground of the ampli
fi
er. If you have HUM noise
problem on one or more loudspeaker try to change the posi on of these switches (o en all up or all down for all the
ampli
fi
ers in the system). Please note that to have an e
ff
ect all cables must be balanced.
4. MIC / LINE switch
This switch adjusts the gain of the LINE/MIC input varying the sensi vity between MIC, suited to connect a microphone,
and LINE, suited to connect a device with high level output like a MIXER, a CD player etc.
NOTE:
do not use the MIC sensi vity to "pump up" the volume with the LINE level equipment, in order to avoid the AD
converter satura on that could produce very annoying distor on.
5. LEVEL control
Rotary level control: it a enuates the level of the signal sent to the LINE input. The a enua on ranges from “0” fully
closed (the signal is completely a enuated) to “10” fully open, nominal level (the signal is not a enuated in any way,
so is fed to the internal ampli
fi
er at the same level at which it arrives on input).
