Xtant P500 is a 5-band parametric equalizer that allows you to adjust the sound of your car audio system to your liking. With its wide range of features, the P500 can be used to improve the sound quality of any system.
- 5-band parametric EQ: The P500 features five bands of equalization, each with its own center frequency, bandwidth, and boost/cut controls. This gives you the flexibility to adjust the sound of your system to your exact specifications.
- Variable Q: The P500's Q controls allow you to adjust the bandwidth of each band of equalization. This lets you narrow in on specific frequencies or broaden the range of frequencies that are affected.

PARAMETRIC EQUALIZATION
The P500 is a 5-band parametric equalizer. Its design
allows the user to vary center frequency, select a “Q” of 1-
10, and select up to 18 dB of boost or cut.
Center frequencies range from 20 Hz to 20 KHz. The on-
board frequency jumper divides the frequency range into three
bands: 20 Hz to 200 Hz, 200 Hz to 2 KHz, and 2 KHz to 20 KHz.
Simply place the jumper in one of the three positions which cor-
responds with the frequency to be adjusted. The specific fre-
quency is then selected via the “frequency” potentiometer
“Q” determines the range of frequencies affected on either
side of the center frequency. “Q” is equal to the center fre-
quency divided by the bandwidth. As “Q” goes up, bandwidth
decreases. The P500’s “Q” adjustment ranges from a narrow
bandwidth of 10 to a very broad bandwidth of 1.
Boost / Cut on the P500 is +/–18 dB. The rotary poten-
tiometer provides continuously variable adjustment.
P500 TUNING SEQUENCE
The P500 is designed to be “set-up” or “tuned” with the aid
of a Real Time Spectrum Analyzer measuring a pink noise sig-
nal generated by the mobile audio system. The analyzer pro-
vides visual feedback when following the steps listed below.
RTA the system and determine points of adjustment. Turn
the system off and place each of the frequency range jumpers
into their corresponding “frequency range” positions.

INSTALLATION SEQUENCE
REMOVE P500 COVER:
Loosen allen head screws and lift-off cover. Do not remove
protective covering on stainless steel lid until installa-
tion is complete.
TEMPORARILY MOUNT P500:
The P500 is designed to be anchored through the four (4)
holes located on the circuit board/base assembly.
MARK WIRES FOR TERMINATION AND REMOVE P500:
Determine wire lengths for Power, Ground & Remote and
mark for cutting/termination. Remove P500 before cut-
ting and terminating all wires. CAUTION: stripping
wires over the circuit board may cause product failure.
INPUT SENSITIVITY:
Make initial adjustment to input gain at your work bench.
Refer to the section “Input Sensitivity” on the reverse
side.
BALANCED LINE:
Make initial adjustment at your work bench. Refer to the
section “Balanced Line” on the reverse side
MOUNT THE P500 AND MAKE ALL CONNECTIONS:
Re-install the P500 and make all wire connections. i.e.
Power, Ground, Remote and RCA input/outputs.
DOUBLE CHECK ALL CONNECTIONS! TURN ON P500:
Check red LED, it should be on.
MAKE ALL EQUALIZATION ADJUSTMENTS:
Refer to “P500 Tuning Sequence” in this “Reference”
ADJUST NOISE GATE THRESHOLD (IF USED):
Refer to “Activating the Noise Gate” on the reverse side
AFTER FINE TUNING THE SYSTEM:
Remove protective covering from P500 and clean. Attach
cover to base.

Perform the following steps per band:
With the system playing pink noise, turn on the
RTA and adjust pink noise SPL to 85 – 90 dB.
Turn the boost/cut control to +18 dB (full clockwise
rotation). This will show the present center frequen-
cy and “Q” settings on the analyzer.
Rotate frequency control to the frequency you wish to
adjust.
Adjust “Q” setting to match the width of the dip or
peak you are addressing.
Finally, adjust the gain control to achieve the desired
response curve.

5 BANDS OF EQUALIZATION ARE AVAILABLE FOR USE. IN
THE 4CH MODE, BOTH THE FRONT AND REAR INPUTS/OUT-
PUTS ARE OPERATIONAL AND THE 3 EQ BANDS LABELED

INPUT SENSITIVITY: FRONT AND REAR INPUT
SENSITIVITY IS DESIGNED TO BE SET INDEPENDENTLY. TO
ADJUST INPUT GAIN, PLACE THE JUMPER IN THE POSITION
WHICH ALLOWS MAXIMUM GAIN BEFORE CLIPPING (DIS-
TORTING). IN THE 2 CHANNEL MODE, ONLY THE FRONT
INPUTS (MAY) REQUIRE ADJUSTMENT.
PLEASE REFER TO THE CHART BELOW WHEN SETTING
INPUT SENSITIVITY. THESE SETTINGS ARE DESIGNED TO BE
A STARTING POINT OR REFERENCE. IF MORE INPUT GAIN IS
DESIRED, MOVE THE JUMPER TO A HIGHER “+” SETTING.
TO ACHIEVE LOWER GAIN, MOVE THE JUMPER TO ONE OF
THE “–” POSITIONS. THE P500 IS SHIPPED WITH THE
F/R INPUT SENSITIVITY SET AT +10 dB.
+20 dB = 100 – 300 mV
+10 dB = 300mV – 1V
0 dB = 1V – 3V
–10 dB = 3V – 8V
–20 dB = 10V – 17V

CUITRY, SIMPLY MOVE THE BALANCED LINE JUMPER TO THE
“ENGAGE” POSITION.
TO USE BALANCED LINE IN THE 2 CHANNEL MODE,
ONLY “ENGAGE” THE FRONT INPUTS.
THE OUTPUTS OF THE P500 ARE NOT BALANCED.
GENERALLY, THE BENEFITS DERIVED FROM BALANCED
INPUTS ARE AVAILABLE AT THE OUTPUTS.
FREQUENCY RANGE JUMPER: EACH BAND OF
EQUALIZATION HAS A FREQUENCY RANGE JUMPER WHICH
DETERMINES THE RANGE OF CENTER FREQUENCIES AVAIL-
ABLE FOR ADJUSTMENT. THREE RANGES ARE AVAILABLE:
20 TO 200 HZ, 200 TO 2,000 HZ AND 2,000 TO
20,000 HZ.
TO SELECT A RANGE, SIMPLY PLACE THE JUMPER IN
THE CORRESPONDING POSITION AS DETAILED IN THE ILLUS-
TRATION. ONCE IN PLACE, THE FREQUENCY ADJUSTMENT
POTENTIOMETER ALLOWS YOU TO SELECT ANY FREQUENCY
WITHIN THAT RANGE.
