PROEL SW118H Manuel De L'utilisateur page 14

GENERAL INFORMATION
Thank you for having chosen a PROEL product. The SW Series is a range of subwoofers designed by Proel to complement
full-range speakers, including the NET and FLASH Series.
Thanks to the variety of size, power and SPL, the SW sub-woofers can offer the perfect low extension solution for any
full-range speaker.
All the SW models feature large voice coil (VC) woofers and a band-pass design, providing very 'punchy' and dynamic lows
together with an extended low frequency response. The SW118H model combine advanced technical characteristics with
state-of-the-art 18" Celestion ferrite speaker. The active version uses a class D amplifier module that can generate up to
1000W of continuous power in a compact and reliable package, it include a stereo preamp section, 24dB/oct. crossover
filters with selectable frequency and phase reverse switch.
The cabinets are built with 18mm plywood and feature 3 metal handles and sturdy 75mm wheels for an easy transport.
SW118HP - PASSIVE VERSION INSTRUCTIONS ( FIG. 1 / 2 / 3)
1. INPUT (SPEAKON)
External amplifier power input: this is the connector where you plug in the power cable coming from your power amplifier
or powered mixer. The powered signal is NOT filtered by an internal passive crossover, so for a better coupling with
external satellite speakers we suggest the use of an amplifier with a 100Hz low pass filter built-in, or the use of an external
analog or digital loudspeaker processor, see the examples section for futher details.
The frequency transition suggested must be in the range of 80-120 Hz. The INPUT speakon has this pin connection:
PIN1+: positive power signal (usually red wire)
PIN1-: negative power signal (usually black wire)
2. LINK (SPEAKON)
Output of the power signal to be sent to another loudspeaker. The connector has the same pin out as specified above.
CHOOSE THE AMPLIFIER POWER
We give you two power-handling numbers: RMS (continuous), and PEAK. So these data suggest you can use any amplifier
with a power capability equal or less the power-handling, but this rule is valid only if the amplifier never clip anytime.
Preventing loudspeaker damage caused by clipping, that is likely the number one cause of damage, and assuming you
want to use the full capability of the loudspeaker, we recommend the use of an amplifier with a built-in limiter to prevent
clipping, in this case the rated power capability must be the same continuous power rating of the loudspeaker into the
same specified impedance (tipically 4 or 8 ohms):
• To obtain the best result using a single SW118HP (with an impedance of 8 ohm), we suggest the use of PROEL HPD-1000
in bridge configuration,
• To obtain the best result using two SW118HP (with an impedance of 8 ohm each), we suggest the use of PROEL HPD-2000
amplifier for a standard stereo configuration.
• To obtain the best result using two SW118HP connected in parallel (with a resulting impedance of 4 ohm), we suggest
the use of an amplifier capable to delivery 2000W at maximum with 4 ohm load.
IMPORTANT: Clipping occurs when the signal at the output of any device in the system (not just the amplifier) reaches its
maximum level. Proper operation of a sound system includes being aware of the types of audio signals being reproduced,
controlling the output levels accordingly, and operating all the devices in the system so that no clipping occurs within
the signal chain.
