    3 Installation Mode of Operation Use switches S1 through S5 to con- figure the P.I.P.-XOV in the desired operating mode. The following five modes are just a sample of the twenty-four different modes which are available: • Mode 3: High-pass to Ch. 1, low- pass to Ch.
  • Page 6 P.I.P.-XOV output connector is provided as a convenient means for “daisy chain- ing” the signal from amplifier to am- plifier. However, please note that modes 8–14 do not provide any out- put signal to the output connector. Also note that modes 15–24 are to be used only with the amplifier con- figured in one of its two mono modes (BRIDGE-MONO or PAR-...

  • Page 7: Low Pass Filter

    The formulas shown below calcu- late the correct component values for the low-pass and high-pass fil- ters. The value of constants K1, K2 and K3 determine the filter type. Notice that the value of resistors R1, R2 and R3 will always be equal. The same is true of capacitors C4, C5 and C6.
  • Page 8 P.I.P.-XOV E x a m p l e 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...

    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 10 Resistors Figure B.1 shows how to read the value of a resistor:...
