GENERAL INFORMATION

Thank you for having chosen a PROEL product. FLASH5 is the latest addition to this succesful PROEL series of louspeaker
systems. Sharing the same stylish design, hi-tech engineering and superior sound quality of the FLASH family, FLASH5 is
the most compact model of the series, designed for a variety or sound reinforcement applications where a full bandwidth,
ultra-compact speaker is required.
FLASH5 is a 2-way system featuring studio-grade transducers in a small-size polypropilene cabinet. A high-fidelity dome
tweeter mounted on an elliptical waveguide is coupled to a 5" woofer with PP cone, providing a detailed and smooth high
frequency response, together with deep and extended lows. The system is available both in active and passive version,
featuring a compact but powerful 100W bi-amp module or an accurately designed crossover filter. The trapezoidal cabinet,
that allows the use also as a wedge monitor, features three M6 threaded points for using dedicated accessories for
installation and a convenient handle for transport. The available accessories include a C-shape metal bracket, an adapter
for microphone stand and a versatile plastic bracket with 2-axys rotation (only for passive version).
The bi-amp module of the active version includes a 20W section for the tweeter and a 80W CLASS D amp for the woofer,
with a carefully designed active crossover for the frequency separation. 2 selectable presets of active EQ provide the
optimal frequency response for a NEARFIELD use as a PC or DESKTOP speaker or for a MIDFIELD use as a musician
MONITOR, an INSTALLATION speaker or a PORTABLE DJ or LIVE system (with SW110 sub-woofer). A DUAL CLIP LIMITER
for the speaker protection and a complete set of connections (XLR, 1/4" JACK and RCA) are also available.
INPUT AND CONTROL INSTRUCTIONS (FIG. 1 / 2 / 3)
1. LINE IN (XLR input)
This is a female XLR connector, which accepts a XLR plug from almost any type of equipment with a balanced or
unbalanced line level outputs. The XLR input is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
2. LINE IN (JACK input)
This is a female JACK connector, which accepts a JACK plug from almost any type of equipment with a balanced or
unbalanced line level outputs. 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.
NOTE: the XLR input connector and the JACK input connector are wired in parallel, so if the XLR connector is used as
input you can use the JACK connector to link another speaker.
3. LINE IN (RCA unbalanced)
These two RCA connectors are wired in parallel, so one can be used for the input and the other for linking another speaker.
The sensitivity is 10dB higher than XLR and JACK, so the RCAs can be used for connecting consumer electronics, such
as computers or CD/MP3 players. The RCA connectors are wired as follows:
Tip = + positive or "hot"
Sleeve = shield or ground
NOTE: Do not use RCA input to connect a professional equipment, due to its higher sensitivity.
NOTE: Do not use RCA input for long cable runs, due to its native unbalanced configuration.
NOTE: Do not use RCA to link two or more speakers with the XLR/JACK as input or viceversa, the internal circuitry of
those inputs are different.
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. LINE LEVEL control
Rotary level control: it attenuates the level of the signal sent to the LINE IN 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
is fed to the internal amplifier at the same level at which it arrives on input).
