2CH / 4CH INPUT MODE JUMPER: THE POSI-
TION OF THE INPUT MODE JUMPER DETERMINES THE OPER-
ATIONAL MODE OF THE EQUALIZER. IN THE 2CH MODE, ONLY
THE FRONT INPUTS AND REAR OUTPUTS ARE USED AND ALL
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
“FRONT A, B &C” ARE TIED TO THE FRONT INPUTS/OUT-
PUTS AND THE 2 EQ BANDS LABELED “REAR A & B”
ARE TIED TO THE REAR INPUTS/OUTPUTS.
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
BALANCED LINE: XTANT’S BALANCED LINE TECH-
NOLOGY MAY BE USED TO ELIMINATE INDUCED AND/OR
GROUND-LOOP RELATED NOISE, RECEIVE SIGNAL FROM A
BALANCED SOURCE, INTERFACE WITH A HIGH LEVEL SIGNAL
(SPEAKER OUTPUTS) AND/OR BE USED AS AN OEM
SOURCE UNIT INTERFACE.
EACH SET OF INPUTS (FRONT/REAR) OF THE P500
FEATURE BALANCED LINE CIRCUITRY. TO ACTIVATE THIS CIR-
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.

BYPASS JUMPERS: THESE JUMPERS
ARE USED TO COMPARE SIGNAL BEFORE
AN AFTER EQUALIZATION. IN 4CH MODE,
THE FRONT AND REAR EQ BANDS MAY BE
BYPASSED INDEPENDENTLY. IN THE 2CH
MODE, ONLY THE JUMPER LABELED
REAR/2CH IS USED TO BYPASS.
