If the mixing board indicates clipping of its output signals, then all of the PVXp™ 15 DSP power capability is not
being utilized cleanly. Clipping the signal before it gets to the PVXp™ 15 DSP is not optimal. Reduce the mixer
output level and turn up the Level control on the PVXp™ 15 DSP.
The amplifiers in the PVXp™ 15 DSP are equipped with “Soft Limiting” circuitry and the LCD will show when
this circuitry has engaged by replacing the normally displayed characters with the word “LIMIT”. If the sound
seems heavily compressed, check the LCD; if it is displaying “LIMIT” more than occasionally, then the drive level
from the mixer (or the Level control on the PVXp™ 15 DSP) needs to be reduced.
When first turning on the sound system, switch on all upstream electronics first, then the PVXp™ 15 DSP with its
Level control fully counterclockwise (all the way down). Begin checking levels with the mixer output level con-
trols all the way down, and bring them up slowly with the PVXp™ 15 DSP Level control set to the
desired setting (one-third way up recommended to start).
It is not good practice to turn the Level control on the PVXp™ 15 DSP all the way up and then try to control level
only from the mixer, this approach would tend to pick up excess noise. Best practice would be to run a “hot” sig-
nal from the mixer down the cable to the PVXp™ 15 DSP, and then turn the PVXp™ 15 DSP Level control up only
as much as necessary to reach full desired output. With this approach, it is necessary to verify the mixer output
is not clipping.
Disconnecting AC Power to the PVXp™ 15 DSP
We recommend that the Power switch (1) be used to turn the unit off first, and then the AC power cord can be
removed, this minimizes stress to the power amplifiers and the transducers from turn-off transients. The pow-
er switch has an arc suppression capacitor to help during turn-off, and tends to make a clean disconnect from
the AC power, while the power cord IEC connector can make intermittent contact before finally becoming fully
disconnected, e.g., as when wiggling the cord.
EQ Modes:
The EQ modes are used to shape the tone of the sound coming out of the speaker. The selections are
as follows:
- Music: Tuned for general music use
- EDM: Used to enhance electronic dance music
- DJ KS 1: Standalone use (no Subwoofer), Indoors
- DJ KS 2: Used with Subwoofer, Indoors
- DJ KS 3: Used with Subwoofer, Outdoors
- KSC: Emulates the sound of popular speakers
- Rock, Country, Hip-Hop: Optimizes the speaker for these typical genres
- Acoustic: Used to enhance acoustic performances
- Voice: Gently rolls off the extreme highs and lows to enhance spoken word
- Church: Tuned for the typical church environment
- Monitor: Optimizes the speaker’s frequency response while being used as a floor monitor
Locate:
Used to optimize the speakers response based on its location. The selections are Pole, Floor and Wall.
Treble:
The treble control can be used to boost or cut the high frequency response of the speaker up to +/-6dB. It
can be used to brighten a dull sound or to reduce harshness.
