GENERAL INFORMATION
Thank you for having chosen a PROEL product.
The new WEDGE Series by PROEL is a complete range of active stage monitors designed to offer not only to professional
musicians and rental companies, but also to amateur musicians and nonprofessional users, a highly valuable monitoring
solution at a very affordable price. Each of the three WD models provides a perfect sound intelligibility and a high SPL
in an extremely lightweight and portable enclosure.
The coaxial transducers, designed under PROEL specifications, represent the best choice for stage monitors, not only
because they fit into more compact cabinets, but also for the fact that they provide a perfect alignment in the emission
of high and low frequencies and a controlled directivity for a perfect listening from any position.
The lightweight CLASS D amplifier modules with SMPS, coupled to a sophisticated analog processing, provide an
impressive sound pressure level, with an extremely detailed response, particularly in the vocal range, and a remarkable
resistance to feedback. Two tailored EQ PRESETS are available for the use of the speaker not only for stage monitoring
(MONITOR), but also as a MAIN SOUND SYSTEM (FOH).
The low-profile, stylish and unobtrusive cabinet, finished with scratch-resistant polyurethane painting, fits perfectly
on any stage.
WD10A, the ultra-compact model of the series, offers a high performance monitoring also on small stages or venues
with a limited space and it's the ideal solution for speech, vocals and keyboards.
WD12A, with its high SPL and its fullrange response, is the favourite choice for vocals, guitar, horns and electronic
instruments or as a high-power monitor for DJs.
WD15A, with its full extension and powerful and deep response at the low frequencies, is the ideal monitor for bass
and drums players. The horn-loaded HF section and the powerful amplifier make it the perfect solution for monitoring
also in very large stages.
INPUT AND CONTROL INSTRUCTIONS (FIG. 1 / 2 / 3)
1. LINE IN (combo XLR-JACK input)
This is a female combo connector, which accepts a XLR or a JACK plug from almost any line level 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 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 lifts the ground of the balanced audio input from the earth-ground of the amplifier. If you have HUM noise
problems on one or more loudspeakers 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.
4. LEVEL control
Rotary level control: it attenuates the level of the signal sent to the LINE 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).
5. SIGN / LIMIT indicator
GREEN LED illuminates to indicate the presence of the signal at the amplifier input.
RED LED illuminates when the internal amplifier's output is limited.
NOTE: When this LED flashes reduce the input signal level.
