Parasource Active Full Range Loudspeakers
The Yorkville Parasource Series of active speaker enclosures are the culmination of Yorkville Sound’s
50 years of experience designing and manufacturing professional audio equipment. Every aspect of
these cabinets, from the hardware and components to the power electronics and processing, repre-
sent years of engineering and considerable advancements over previous generations. The result is a
modern workhorse that can be considered to be an industry leader.
These Parasource products are designed and built in Canada.
We feel they are so well built that we give a 2-year unlimited warranty.
The Amplifier
At the heart of the powered enclosures are the all new Parasource amplifiers. The Parasource amps
have been designed for increased output while minimizing size and weight. Further reductions in
weight have been achieved by developing an efficient switching power supply to feed the amps.
Housed in a custom die-cast aluminum chassis, the Parasource amplifiers is designed to passively
dissipate its heat, eliminating the need for a noisy fan.
The PS10P uses a 400 watt (800 watts peak) amplifier to drive the 10-inch long throw woofer
(2-inch voice coil) and a 400 watt (800 watts peak) amp on the 38 mm voicecoil (1-inch exit)
compression driver.
The PS12P uses a 950 watt (3500 watts peak) amplifier to drive the 12-inch long throw woofer
(3-inch voice coil) and a 450 watt (900 watts peak) amp on the 38 mm voicecoil (1-inch exit)
compression driver.
The PS15P uses a 950 watt (3500 watts peak) amplifier to drive the 15-inch long throw woofer
(3-inch voice coil) and a 450 watt (900 watts peak) amp on the 38 mm voicecoil (1-inch exit)
compression driver.
The Digital Signal Processor
All signals going into the Parasource amplifiers pass through a DSP running Yorkville’s latest filter pro-
cessing software. An automatic input gain ranging scheme allows for a wide dynamic range without the
risk of clipping or increased audio converter noise. The Club and Concert modes help choose between
increased low frequency content and extended horn output. Internal multi-band audio limiting makes it
possible to limit several audio bands separately. This solves the problem of a kick drum pulse affecting
the level of other instruments or vocals. Additional limiters are employed to ensure the power of the am-
plifiers is safely delivered to the speakers without exceeding their power handling capabilities.
The Cabinet
The cabinet of the Parasource enclosure is formed in ABS plastic. Internal bracing allows for a
lighter cabinet while ensuring cabinet resonances are minimized. The newly designed conical horns
(90°x70° on the PS10P and 85°x50° on the PS12P and PS15P) offer an extended horizontal disper-
sion pattern delivering better off-axis coverage for the mid and high frequencies. Cast handles and
molded pick up points make the cabinet easy to move. The cabinets also feature embedded fly points
allowing for safe hanging for installs.
Operation
The Parasource enclosures are bi-amped full-range loudspeakers with a built-in two channel mixer.
Multiple Parasource cabinets can be connected through the Link option. If you’re using a Parasource
enclosure with an external mixer the internal mixer can be disabled. The built-in mixer has a micro-
phone input and a line level input which sums a ¼-inch balanced jack and mono-summed RCA jack.
Advanced signal processing is used to provide maximum performance at all levels. There’s a switch to
provide low frequency rolloff (if using the Parasource enclosure with a subwoofer) and a Club/Concert
switch for application specific equalization.
