CH-2 CH-1 GND 1 2 Fig. 1.1 P.I.P.–BP1X Shown 1 Welcome Features Congratulations on your purchase of Crown’s P.I.P.–BP1X or P.I.P.–BP1C. PIP™ modules are designed to quickly install in the back of many Crown amplifiers. PIP stands for “Programmable Input Processor.” Each PIP has features that expand the capabilities of your amplifier, enabling you to customize it for your particular needs.

P.I.P.–BP1X & P.I.P.–BP1C 2 Controls,Connectors & Setup A/B. Connectors Balanced 3-pin XLR or quick-disconnect removable barrier block connectors are provided for the inputs and outputs. The P.I.P.-BP1X is supplied with XLR Jacks: a female XLR for the input connector and a male XLR for the daisy chain output. These connectors are wired for pin 2 = Hot. The P.I.P.
P.I.P.–BP1X & P.I.P.–BP1C response that must be corrected electronically by this filter. The actual response is determined by the combination of a stage of first-order boost (controlled by switches 8, 9, and 10) and a stage of second-order highfrequency roll off (controlled by switches 1-6), Note: switch 7 is not active and can be set at either the“ON” or“OFF”position. The loudspeaker manufacturer determines the frequencies to which these switches should be set.
P.I.P.–BP1X & P.I.P.–BP1C J. Input Ground Lift Jumper The unit is shipped from the factory with pin 1 of each input XLR connected to signal ground through independent 0-ohm resistors. If hum problems are experienced, the appropriate resistor may be removed. This will then connect pin 1 of the XLR from that channel to signal ground through an 82-ohm resistor in parallel with a 0.1µF capacitor.

P.I.P.–BP1X & P.I.P.–BP1C 3 Installation To avoid damaging the P.I.P.–BP1, turn off the amplifier’s power before making any changes (the P.I.P.–EXT accessory should not be used to adjust settings with the power on). + – + – Input/Output Wiring Both models of the P.I.P.–BP1, have balanced inputs and daisy-chain outputs. XLR connectors are supplied with the P.I.P.–BP1X and are wired such that pin 1 is ground, pin 2 is noninverting (“hot”), and pin 3 is inverting. (Figures 3.1 and 3.2 illustrate this.
P.I.P.–BP1X & P.I.P.–BP1C Installation 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 the amplifier’s level controls down, turn it off and remove the AC power. Don’t touch the circuitry. Even though the amplifier is off, there could still be enough energy remaining to cause electric shock. 1.
