These ultra-portable speakers combine, in carefully engineered and light-weight cabinets, the clearest and most accurate
PROEL sound with Class D amplifi er technology and Switch Mode Power Supply, off ering an unbeatable PA solu on at
its price point.
V8A model features an extremely effi
cient amplifi er module capable of delivering 400 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 protec on, perfect insula on of the cabinet from the outside and extremely effi

Thanks to the carefully selected speakers and to the sophis cated ac ve 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

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 = + 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 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 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 analog
input satura on that could produce very annoying distor on.
4. GND LIFT switch
This switch li the ground of the balanced audio inputs from the earth-ground of the amplifi 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
amplifi ers in the system). Please note that to have an eff ect all cables must be balanced.
5. LEVEL control
Rotary level control: it a enuates the level of the signal sent to the 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 it is
fed to the internal amplifi er 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 fl oor as stage monitor.
