Setting up the
Versarray System
Processor Settings for Versarray 112Neo & Subs with VSX 26/48
(also Digitool/Prolinx)
Single VR112 Neo Cabinet w/118 Sub
Front End EQ (before the crossover section) = PEQ –2.0 dB @ 2k, bw= 0.6 (or use
1/3 octave band at 2 kHz set to –2.0 dB);
Infrasonic filtering: 24 dB/oct. LR @ 34 Hz)
Crossover settings:
Woofer= 24 dB/oct. LR @ 2.0 kHz, Tweeter= 24 dB/oct. Bessel @ 3.0 kHz, Woofer
Polarity Normal, Tweeter Polarity Normal
Sub to Woofer Crossover: Sub= 24 dB/oct. LR @ 125Hz, Woofer= 24 dB/oct LR @
100Hz, Sub Polarity Normal, Woofer Polarity Normal
EQ after crossover:
Woofer EQ = PEQ +1.5 dB @ 560 Hz, bw=0.5; PEQ -3.5 dB @ 850 Hz, bw=0.5
PEQ +3dB @ 115 Hz, bw= 2; PEQ –1.5 dB @ 2.2 kHz, bw=.7;
PEQ –2 dB @ 700 Hz, bw=3.0 Woofer Delay = 0.0 ms (none)
Tweeter EQ: PEQ –3 dB @ 2.7 kHz, bw= 0.7; PEQ +2.5 dB @ 4.6 kHz, bw= 1.0;
PEQ +3.5 dB @ 16.5 kHz, bw=1.0 Tweeter Delay = 0.0 ms (none)
Sub EQ: PEQ +4.0 dB @ 50 Hz, bw= 0.7; PEQ -2.5 dB @ 100 Hz, bw= 0.5
Line curvature, or splay between cabinets
Splaying the line will tend to require more level increase from the tweeters, and some
more cut EQ at 1.8 kHz.
A uniform splay of 2.5 degrees between cabinets for an 8 cabinet array would need
approximately 2 dB of tweeter boost, and 0.5 dB of 12” woofer level increase, relative
to a subwoofer level. A uniform splay of 5 degrees per cabinet for an 8 cabinet array
would require approximately 5 dB of tweeter level boost, and approx. 1 dB of 12”
woofer level increase, relative to a subwoofer.
Complete processor settings for the recommended 2.5 degree continuous
curvature with 6 Versarray™ 112 cabinets and one Versarray™ 218 Sub:
Front End EQ (before the crossover section) = PEQ –4.0 dB @ 2k, bw= 0.7 (or use
1/3 octave band 2 kHz set to –2.5 dB AND 1/3 octave band 1.6 kHz set to –2 dB)
Infrasonic filtering: 24 dB/oct. LR @ 34 Hz)

Sub EQ: PEQ +4.0 dB @ 50 Hz, bw= 0.7; PEQ -2.5 dB @ 100 Hz, bw= 0.5
Level Settings (for same model of power amp, with all channels set to the same
voltage gain): One Versarray™ 218 Sub = +4 dB
Versarray™ 112: Woofer= 0.0 dB, Tweeter= +8.5 dB (for ribbons wired 16 ohms)
SPECIAL NOTE: Versarray™ 218 Sub is in 4 ohm mode (woofers paralleled).
If the Versarray™ 218 Sub woofers are driven separately, using an amp with the
same gain as all the other amps, then drive level does not increase.
A word about system low end
The above settings will produce a nominally “flat” system. It is currently fashionable
for modern systems to have 6 dB to 15 dB boost in output compared to midband. If
this is desired then simply do not cut the drive to the subs and if necessary turn the
attenuator clockwise to wide open. If such drastic response is required consider
using an “Aux Fed Sub” arrangement.
Dynamics settings:
The following settings have been chosen to provide a reasonable balance between
dynamic range and speaker protection. You may wish to save an additional preset
with “safe mode” settings by reducing the threshold by 6 dB. It is often a good idea to
start the system up in the safe mode until it is determined that everything is running
correctly and the system operator is capable of “safe driving”. The trade off is more
protection for less dynamic range.

Amplifier Level Settings:
Sensitivity set at –10 dB is recommended when using Peavey CS series amps.
All channels set to the same voltage gain, referenced to the 12” woofer)
Crest power amps should be used with the sensitivity setting in the x20 position and
the attenuators fully clockwise (wide open)

website
VSX presets:
A VSX 26 may be used to provide a conventional 2 channel/stereo three way control
of any Versarray System. The VSX 48 should be selected when it is desirable to
control the system in “zones” that may be used to split coverage between balconies
and a main floor or when shading of EQ or Level is desired. The added control
provided by the VSX 48 gives the user additional capabilities to fine tune the system.
The VSX 48 presets also provide an easy means to use an “aux fed sub” system
(see our white paper … http://www.peavey.com/support/technotes/)
VSX26 presets:
Input A to
out 1 – subs
