GENERAL INFORMATION

Thank you for having chosen a PROEL product.

The SW Series is a range of sub-woofers designed to complement PROEL full-range passive or ac ve speakers. The variety

of size, power and SPL oﬀ ered by the ﬁ ve SW models provides the perfect low extension solu on for any speaker model

available in the PROEL range.

All the SW models feature large VC woofers and band-pass or vented design, which provide very ‘punchy’, dynamic lows

together with an extended low frequency response.

The CLASS D ampliﬁ er modules can generate a massive amount of con nuous power in a compact and reliable package.

All the modules include a STEREO pre-amp sec on, 24dB/oct. crossover ﬁ lters with selectable frequency and PHASE

reverse switch. The cabinets are built with 15/18mm plywood and feature 2 or 3 metal handles and sturdy 75mm wheels

for an easy transport.

SW115P - PASSIVE VERSION INSTRUCTIONS ( FIG. 1 / 2 / 3)

1. INPUT (SPEAKON)

External ampliﬁ er power input: this is the connector where you plug in the power cable coming from your power

ampliﬁ er or powered mixer. The powered signal is ﬁ ltered by an internal passive crossover with a low-pass ﬁ lter for the

internal subwoofer speaker, and with a high-pass ﬁ lter for an external satellite speaker. The frequency transi on is about

at 160 Hz connec ng an 8 ohm satellite speaker. The INPUT speakon has this pin connec on:

PIN1+: posi ve power signal (usually red wire)

PIN1-: nega ve power signal (usually black wire)

2. HI-PASS OUTPUT (SPEAKON)

Output of the power signal to be sent to a satellite loudspeaker. This output is ﬁ ltered by a so -slope high-pass, to obtain

an op mal coupling with any kind of satellite. The connector has the same pin out as above.

CHOOSE THE AMPLIFIER POWER

We give you two power-handling numbers: AES or CONTINUOUS, and PEAK. These data suggest you can use any ampliﬁ er

with a power capability equal or less the power-handling, but this rule is valid only if the ampliﬁ er never clips.

Preven ng 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 ampliﬁ er with a built-in limiter to prevent

clipping: in this case the rated power capability must be the same as the con nuous power ra ng of the loudspeaker

into the same speciﬁ ed impedance ( pically 4 or 8 ohms):

• To obtain the best result using two SW115P connected in stereo without the satellite speakers (with an impedance of

8 ohm each), we suggest the use of PROEL HPX-1200 ampliﬁ er set as standard stereo conﬁ gura on.

• To obtain the best result using two SW115P connected in stereo with two respec ve satellite speakers (with an

impedance of 8 ohm each), we suggest the use of PROEL HPX-2400 ampliﬁ er set as standard stereo conﬁ gura on.

IMPORTANT: Clipping occurs when the signal at the output of any device in the system (not just the ampliﬁ er) reaches

its maximum level. Proper opera on of a sound system includes being aware of the types of audio signals being

reproduced, controlling the output levels accordingly, and opera ng all the devices in the system so that no clipping

occurs within the signal chain.
