GENERAL INFORMATION

Thank you for having chosen a PROEL product.
V HDA are portable, ultra-compact loudspeaker systems featuring carefully designed transducers combined with a
powerful 1200W Class D amplifier and PROEL high-resolution CORE DSP technology, for an unmatched performance in
their class.
The high-excursion 3" VC woofers, combined with CELESTION precision compression drivers mounted on the V Series
wide coverage waveguide, produce an impressive sound pressure level with a flat and extended response and a sound
you usually expect from top-class professional systems.
The 1200W Class D / SMPS amplifier module, hosted in a fully sealed aluminium box, provides a massive amount of
power in a surprisingly compact and lightweight package, raising the system's portability to a new standard.
For processing the V HDA the PROEL's R&D Lab has developed a new version of the proprietary CORE DSP, able to deliver
ultimate performance to the system tuning. Thanks to accurate crossover and EQ filters, precise compressors/limiters
for the dynamic control and delay lines for the time alignment, the CORE DSP provides a high-class signal management
and the highest sound pressure level with the best sound quality.
The V HDA Series comprehensive and intuitive control interface features a single knob and a large LCD display for
controlling the sound level and 2-band EQ. 5 presets (MUSIC, LIVE, DJ, MONITOR, SPEECH) allow to tailor the system's
sound in order to get always the best sound for all kind of applications. The CORE DSP includes also an intelligent
Dynamic EQ with three different presets, able to adapt dynamically the sound equalization and to obtain always the
best acoustic response at any signal level.
This impressive set of features and technology is packed into one of the most compact and lightweight package available
in its class, combining maximum portability with top performance.

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 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. MIC IN (XLR input balanced)
This is a female XLR connector, which accepts a balanced microphone input from a dynamic microphone. The XLR input
is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
3. LINE IN LEVEL control
This analog control reduces the level of the signal connected to the LINE IN socket (the signal is reduced before the AD
converter). The reduction ranges from "10" fully open (nominal level) to "0" fully closed.
4. MIC GAIN control
This control allows the signal from the microphone connected to MIC input to be adjusted to optimal levels. The gain is
at minimum with the knob all way down, ramping up to maximum gain when rotated fully clockwise.
5. MIX OUT (XLR output unbalanced)
This XLR connector provides an unbalanced line-level signal that represents the mixed mic and line signals. You can
connect it to the input of another powered speaker to make an array.
NOTE: the signal from MIX OUT is the summation of LINE IN and MIC IN signals, so its level depends on the position of
LINE IN LEVEL and MIC IN LEVEL controls.
