Mode Switch - YORKVILLE Parasource Série Manuel De L'utilisateur

Introduction
PS12s, PS15s and PS18s
Congratulations on your purchase of a Parasource Series subwoofer the best option when adding a
subwoofer to Yorkville Sound's Parasource Series powered speaker enclosures. The PS12s, PS15s and
PS18s are premium-quality subwoofers with integrated power amplifiers.

1. Mode Switch

The Mode switch is provided to choose between line-level and speaker-level signals.
The line-level position is used when the PS12s, PS15s and PS18s are fed a signal from a processor,
electronic crossover, the output of an un-powered mixer or the loop-through of a powered
speaker cabinet. When in line-level mode, using balanced ¼-inch (Tip, Ring, Sleeve) and/or XLR
cables will reduce the unit's sensitivity to hum and buzz.
For speaker level operation, connect the PS12s, PS15s and PS18s just like an ordinary speaker (in
parallel using the loop-through jacks) along with the passive full-range loudspeakers. The speaker
level position should be used when the PS12s, PS15s and PS18s are fed with a ¼-inch speaker
cable directly from the output of an amplifier or a powered-mixer. You can also use a speaker
level signal from the parallel connection on an un-powered speaker cabinet.
2. The PS12s, PS15s and PS18s' Level Control
The Level control adjusts the amount of bass added to the sound system by the Parasource
subwoofer. This control adjusts for the relative sensitivity of the companion full-range loudspeakers
and the desired system frequency response. This control should be set by listening with a medium-
level input signal (such that the limiter is not firing).
Note: It's not recommended to set this control at high levels since the limiter will then
greatly affect the output level .
Note: Setting the PS12s, PS15s and PS18s Level control at the center detent is the correct
starting point when setting up a sound system. From there, adjustments can be made for
the best sound. The detent is the setting that will give full power when the line input is used
and the input signal is at a level of +3 dBV.
