See illustration for direction of arrows for Nominal Setting. Bottom pot should always be maximum CW. IRS amplifier output can be “trimmed” in relation to each other by powering system up with amp cover removed, attaching DMM to main amp terminals and comparing output voltage, driving with 50Hz signal to achieve approx. 5.0 volts at main amp terminals. If amp voltages are not equal on both towers, carefully adjust (raise/lower) Center ACCELERATION/FEEDBACK pot on one unit until they are. Connect an AC voltmeter to these test points to assure high speed of cooling fan is working. With AC meter attached to these points with COLD system, voltage should be less than 100v. Drive system at 20-30Hz either into woofer tower load or 1-2 ohm 500 watt resistor bank on bench at reasonably high power. When system heats sufficiently, warp switch should audibly trip and raise voltage to over 100v. With AC ammeter on 120v power cord, nominal AC current should = 0.40A with no signal input. If not adjust at indicated test point. Line Fuse ratings 120v = 12 amps slo-blo 240v = 8 amps slo-blo Control Woofer is the third woofer from the bottom in the tower 19 IRSV MECHANICAL PARTS LIST MODEL: IRS V(IF970400) NLA = No Longer Available CABINETS/WINGS/BASES/TOP PIECESNLA FRONT GRILLESNLA CONTROL CABLE (2)NLA AMPLIFIER 120V (2)A036-3089 AMPLIFIER 220V (2)A036-3096 (Currently NLA) ELECTRONIC CROSSOVER UNITA048-3088 TWEETER - EMIT902-3721 (Currently NLA) MIDRANGE - EMIM902-0012D (Currently NLA) 12 WOOFER (10)902-3102 CONTROL WOOFER 12 (2)A028-3103 (Currently NLA) DIAPHRAGM ONLY - TWEETER751-3722 (Currently NLA) DIAPHRAGM ONLY - MIDRANGE751-3806 (Currently NLA) PASSIVE CROSSOVER ASSEMBLY (2)NLA (SEE DRAWING FOR PART NUMBERS OF COMPONENTS) RCA SIGNAL CABLE639-3199 OWNERS MANUAL930-3095 20 PARALLEL 21 22 23 24 25
