PSA1s Introduction
Congratulations on your purchase of the PSA1s. The PSA1s is a premium-quality integrated sub-
woofer and power amplifier. It has been designed to be the perfect complement to our Paraline Series
PSA1 powered speaker.
1. Input Level Switch
The Input level switch is provided to choose between line-level and speaker-level signals.
The line-level position is for use when the PSA1s is fed a signal from a processor, electronic cross-
over, the output of an un-powered mixer, or the loop-through of a powered speaker cabinet. When us-
ing the line-level mode, the use of balanced ¼-inch (Tip, Ring, Sleeve) and/or XLR cables will reduce
the unit’s sensitivity to hum and buzz.
The speaker level position should be used when the PSA1s is fed with a ¼-inch speaker cable
from the output of an amplifier or a powered-mixer, or from the parallel connection on an un-powered
speaker cabinet. For speaker level operation, connect the PSA1s just like an ordinary speaker (in paral-
lel using the loop-through jacks) along with the passive full-range loudspeakers.
2. PSA1s Level Control
The Level control adjusts the amount of bass added to the sound system by the PSA1s. 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 is not recommended to set this control at high levels since the limiter determines
the output level.
Note: A setting at the center detent on the PSA1s Level control 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.
3. Input Jacks
The inputs are designed to make it easy to hook up your PSA1s to almost any audio system with
minimal hassle. Both ¼-inch and XLR inputs and Thru connections are supplied.
The PSA1s may be plugged in before or after the full-range loudspeaker. The PSA1s does not alter
the signal to the daisy-chained (thru) loudspeakers and will not draw any power from the host amplifier/
processor driving them. Also, note that an external crossover is not necessary when using the PSA1s.
Note: As well as accommodating full-range loudspeakers, the Thru jacks allow many PSA1s
subwoofers to be connected in a string (parallel). There is no practical limit to the number of
PSA1s subwoofers that may be connected together.
