GENERAL INFORMATION
Thank you for having chosen a PROEL product.
V Series is the new generation of PROEL powered loudspeakers delivering absolute value in terms of performance,
engineering and design.
These ultra-portable speakers combine, in carefully engineered and light-weight cabinets, the clearest and most accurate
PROEL sound with Class D amplifier technology and Switch Mode Power Supply, offering an unbeatable PA solution at
its price point.
All the three models feature an extremely efficient amplifier module capable of delivering 600 W of robust power to
the transducers. Thanks to the use of SMPS technology, this power comes in an ultra-lightweight package, making the
V models the most portable PROEL speakers ever. The power module is hosted in a fully sealed aluminium box, which
provides protection, perfect insulation of the cabinet from the outside and extremely efficient cooling.
Thanks to the carefully selected speakers and to the sophisticated active electronics, including dual CLIP LIMITERS for
an undistorted sound even at the loudest level, the sound of the V Series has been precisely tuned in every details, in
order to provide unheard performance in this price range.
The V series cabinets, expression of the most advanced Italian design, include a super-comfortable luggage-style top
handle for an effortless portability. The slanted shape allows the V speakers to be laid on their side and used also as
stage monitors.
INSTRUCTIONS (FIG. 1 / 2 / 3)
1. INPUT (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 = + positive or "hot"
Pin 3 = - negative or "cold"
The JACK input is wired as follows:
Tip = + positive or "hot"
Ring = - negative or "cold"
Sleeve = shield or ground
When connecting an unbalanced signal, wire them as follows:
Pin2 / Tip = + positive 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 respective INPUT socket, so the LINK is wired as INPUT.
Connect these to the inputs of other powered speakers to make an array.
3. MIC / LINE switch
This switch adjusts the gain of the LINE/MIC input varying the sensitivity 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 sensitivity to "pump up" the volume with the LINE level equipment, in order to avoid the analog
input saturation that could produce very annoying distortion.
4. GND LIFT switch
This switch lift the ground of the balanced audio inputs from the earth-ground of the amplifier. If you have HUM noise
problem on one or more loudspeaker try to change the position of these switches (often all up or all down for all the
amplifiers in the system). Please note that to have an effect all cables must be balanced.
5. LEVEL control
Rotary level control: it attenuates the level of the signal sent to the INPUT. The attenuation ranges from “0” fully closed
(the signal is completely attenuated) to “10” fully open, nominal level (the signal is not attenuated in any way, so it is
fed to the internal amplifier at the same level at which it arrives on input).
6. LOW control
This control gives you up to 6 dB boost or cut at 90 Hz with a "SHELVING" curve shape. Use it to add or reduce the sound
"punch", or to reduce the low frequency rise when the speaker is set near walls or on floor as stage monitor.
