P.I.P.–EDCb CH-2 CH-1 PUSH PUSH EDCb INPUT INPUT 3 Programmable Input Processor (P.I.P.) GND 1 2 Fig. 1.1 P.I.P.-EDCb 1 Welcome Thank you for purchasing the Crown P.I.P.-EDCb . P.I.P. ® modules are designed to quickly install in the back of many Crown amplifiers. P.I.P. stands for “Programmable Input Processor.” Their versatile features expand the capabilities of your amplifier and enable you to customize it for your particular needs. input signal level is sensed.

DIP Switches (S1, S2) A balanced XLR connector is provided for input to each channel. The pin assignments are labeled on the face of the P.I.P. Refer to your amplifier Owner’s Manual for wiring details. A nine-segment DIP switch is provided for each channel.
P.I.P.–EDCb maximum output voltage and can be used to protect loudspeakers and listeners. When turned to the maximum setting (fully clockwise), the compressor responds only to the channel’s IOC error signal. When set lower, the compres- sor responds to a maximum audio level (see Figure 3.4). D. Tracking Jumper (Z1) Moving this jumper to the “ON” position causes the compressors to track each other.
P.I.P.–EDCb 3 Installation Before installing the P.I.P. module, it should first be configured. Compressor Setting 3.1 P.I.P. Configuration 1. Set the corner frequency (–3 dB frequency) for each subsonic filter with DIP switches S1 and S2 (see Figure 3.2). Notice that the first six switch segments control the corner frequency.

P.I.P.–EDCb into the PIP2 input adapter (see Figure 3.7) and insert the assembly into the P.I.P. opening in the back of the amplifier. 4. Secure the P.I.P.–EDCb with the two screws and lock washers provided. (The lock washers are important because they bond the P.I.P. to the chassis ground of the amplifier.) 5. Connect input and output wiring. 6. Plug in the amplifier and turn it on. Adjust its level controls to a desired setting. Do not tamper with the circuitry.
