INTRODUCTION
Thank you for choosing this PROEL product and for your trust in our brand, synonymous of professionalism,
accuracy, high quality and reliability. All our products are CE approved and designed for continuous use in
professional applications.
DESCRIPTION
S Series is new range of compact and powerful sub-woofers designed to complement PROEL full-range
passive or active speakers. The variety of size, applicable power and SPL offered by the three passive S
models provides the perfect low extension solution for any speaker model available in the PROEL range.
All the S models feature high-excursion woofers in a Hybrid Band Pass configuration (HBP). This innovative
design provides a higher efficiency compared to direct radiation sub-woofers and, in addition, guarantees a
much better coupling of the tuning ducts with the external air, reducing the distortion and the air turbulence,
for a more defined sound and deep and punchy lows.
The cabinets are built with 15 / 18mm plywood and finished with extra-durable polyurethane paint. They
feature two flush handles and four sturdy 75mm wheels for an easy transport (S15 and S18 only).
INSTRUCTIONS
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 to
obtain the optimal coupling with external satellite speakers you must use an external analog or digital
loudspeaker processor or an amplifier with a built-in crossover filter (see the examples section for further
details).
The suggested filtering frequency must be in the range of 80-160 Hz. The INPUT speakon has this pin
connection:
PIN1+: positive power signal (usually red wire)
PIN1-: negative power signal (usually black wire)
