P.I.P.-XOV Fig. 1.1 P.I.P.-XOV 1 Welcome Thank you for purchasing the Crown P.I.P. ® -XOV accessory. PIP TM modules are designed to quickly install in the rear panel of many Crown amplifiers. PIP stands for “Programmable Input Processor.” Their versatile features expand the capabilities of your amplifier and enable you to customize it for your particular needs. The P.I.P. -XOV is a versatile and economical mono crossover filter that plugs into Crown amplifiers with PIP compatibility.

P.I.P.-XOV 2 Facilities A. Thumb Screws Use these two thumb screws to fasten the PIP to the amplifier. An E-ring prevents them from falling out. B. Balanced Phone Jacks A balanced 1/4-inch phone jack is provided at both the input and output of the P.I.P.-XOV. Each phone jack is parallel to its XLR connector counterpart. C. XLR Connectors A balanced 3-pin XLR connector is provided at both the input and output. A female connector is used for the input and a male connector is used for the output.
P.I.P.-XOV 3 Installation nal to the output connectors for daisy-chaining. • Mode 16: Band-pass to Ch. 1 for mono operation, with unprocessed signal to the output connectors for daisy-chaining. • Mode 20: High-pass to Ch. 1 for mono operation, with low-pass signal routed to the output connectors. • Mode 22: Low-pass to Ch. 1 for mono operation, with high-pass signal routed to the output connectors. Mode of Operation Use switches S1 through S5 to configure the P.I.P.-XOV in the desired operating mode.
P.I.P.-XOV output connector is provided as a convenient means for “daisy chaining” the signal from amplifier to amplifier. However, please note that modes 8–14 do not provide any output signal to the output connector. Also note that modes 15–24 are to be used only with the amplifier configured in one of its two mono modes (BRIDGE-MONO or PARALLEL-MONO). When the P.I.P.XOV is placed in one of these modes, no signal will be fed to the input of Channel 2.
P.I.P.-XOV The formulas shown below calculate the correct component values for the low-pass and high-pass filters. The value of constants K1, K2 and K3 determine the filter type. Resistor R6 should always be less than 1 M ohm. The value of capacitors C4, C5 and C6 can be any arbitrary value so long as it allows R1–R6 to meet the above criteria. Notice that the value of resistors R1, R2 and R3 will always be equal. The same is true of capacitors C4, C5 and C6.
P.I.P.-XOV Example Suppose that you need a 0.25 Chebyshev high-pass filter with a 400 Hz cutoff. The preceding chart shows the correct values for K1–K3: K1=2.018, K2=8.551, and K3= 0.1109. Next choose an arbitrary value for C (C4, C5, C6) which yields R4 and R5 values approximately within the range of 2 K to 330 K ohms and a value for R6 less than 1 M ohm. For this example, let C=0.01 mF. Then:R4 = (1 / 2.018) / (2 x 3.14159 x 400 x 0.01 x 10E–6) = 19,717 ohms. R5 = (1 / 8.551) / (2 x 3.14159 x 400 x 0.
P.I.P.-XOV A guide to reading resistor color codes is included in Appendix B for your convenience. Installation Procedures You may need a phillips screwdriver to remove the existing PIP module or panel from your amplifier. CAUTION: Before connecting this or any PIP to your amplifier, it is important to turn its level controls down, turn it off and remove the AC power. Don’t touch the circuitry while the amp is plugged in.

P.I.P.-XOV Appendix B: Reading Component Values Capacitors Capacitors’ values are usually stamped on the capacitor. However, not all capacitors are labeled the same way. For example, a 0.022 microfarad (µF) capacitor may be marked as .022 K, 22n, .022 µF, or 223 K. The last example could be read 22 x 103 picofarads (pF), where 1 pF=106 µF. Resistors Figure B.
