1 Welcome

Congratulations on your purchase of Crown's P.I.P.-BP1X or P.I.P.-BP1C PIP^TM 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.

The P.I.P.-BP1X and P.I.P.-BP1Care versatile stereo Band-Pass processors that plug into any PIP-capable Crown amplifier. TheP.I.P.-BP1Xuses XLR connectors and the P.I.P.-BP1C uses a removable barrier block. Each channel of the PIP is completely independent from the other and combines the functions of a low-pass filter, a high-pass filter, vented-speaker box equalization, horn equalization and compression.

DIP switches and convenient jumper blocks make it easy to configure any of its powerful operating features.

Features

☐ Variable 24-dB/octave (4th order) Butterworth low-pass filter.
☐ Variable 24-dB/octave (4th order) Butterworth high-pass filter.
☐ Variable 12-dB/octave (2nd order) low-frequency filter with Q=2 for vented box equalization.
☐ Variable 6-dB/octave high-frequency shelving network with variable 12-dB/octave high-frequency low-pass filter for constant-directivity horn equalization.
☐ Variable threshold, feedback/error-driven compressor/limiter with infinite compression ratio.
☐ Configurable compressor control path.
☐ Configurable "daisy chain" outputs.
☐ Balanced 3-pin XLR connectors or quick-disconnect removable barrier block connectors (depending on model) for input and daisy chain outputs.

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.-BP1C is supplied with quick-disconnect removable barrier block connectors; mating connectors are supplied to allow the user to quickly disconnect an input or output and move it to the other channel. These connectors are wired pin1=Hot. (See Section 3 for input and output wiring examples.)

C. Low-Pass Filter DIP Switches

The input signal is processed first by a 4th-order (24-dB/octave) low-pass filter network with a Butterworth response characteristic. Four eight-segment DIP switches (S100,S101,S102 and S103 for channel 1),(S200,S201, S202 and S203 for channel 2) select the low-pass filter frequency at which the output is -3-dB down from the input. (See Figure 2.2 for a complete table of frequencies and settings and Figure 2.3 for sample frequency-response graphs.) Note that all four DIP switches must use the same settings for the response to be correct. These DIP switches are factory-set to 20 kHz.

D. High-Pass Filter DIP Switches

The signal is processed next by a 4th-order (24-dB/octave) high-pass filter network with a Butterworth response characteristic. Four eight-segment DIP switches(S104,S105,S106 and S107 for Channel 1), (S204,S205,S206 and S207 for Channel 2) select the high pass filter frequency at which the output is -3-dB down from the input. (See Figure 2.2 for a complete table of frequencies and settings and Figure 2.4 for sample frequency-response graphs.) Note that all four DIP switches must use the same settings for the response to be correct. These DIP switches are factory-set to 23 Hz.

E. Low-Frequency Equalization DIP Switches

Following the high-pass filter is a 6th-order loudspeaker equalization feature. A ten-segment DIP switch (S108 for Channel 1); (S208 for Channel 2) sets the +6 dB boost frequency of the vented-box equalization filter. Note: (Switch 7 is not active and can be set to either the "ON" or "OFF") position. This feature is used for loudspeakers that have been designed as a 6th-order system and require 2nd-order equalization to achieve optimum performance. The filter uses the Sallen-Key non-inverting second-order high-pass topology. The loudspeaker manufacturer determines the frequency to which this filter should be set. Low-Frequency Equalizaion is factory-set to Flat (Figure 2.5 shows a complete listing of equalization points and the corresponding switch positions; Figure 2.6 shows typical response curves for the filter).

F. Constant-Directivity Horn Equalization DIP Switches

This ten-segment DIP Switch (S109 for Channel 1)); (S209 for Channel 2) sets both the +3-dB shelving frequency and the -3-dB low-pass roll-off frequency of the constant-directivity horn equalization filter. Constant-directivity horns have an inherent roll-off in their

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 high-frequency 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. Constant-Directivity Horn Equalizaion is factory-set to Flat. Refer to Figure 2.7a for -3-dB low pass roll-off frequency settings and corresponding switch positions. Refer to Figure 2.7a for +3-dB shelving frequency settings and corresponding switch positions. Figure 2.8 shows sample response curves.

G. Compressor Threshold Potentiometer

The compressor occurs in the signal path after the filters and equalizers. A variable-threshold signal-driven compressor is provided and by default is ON and is error driven. With error-driven compression, the compressor will activate if the amplifier clips, regardless of the output signal. Error-driven compression is useful when the possibility of over-driving the amplifier by several dB is present and the resulting distortion is unacceptable.

Reducing the output voltage at which the compressor will activate is useful for applications where driver and/or system protection is desired. Compression will then limit the output voltage to a predetermined level, even as the input to the amplifier is increased.

Attack time is 10 msec and release time is 360 msec. The compressor has an infinite compression ratio, meaning that when the threshold is reached, an increase in input level will not result in a change in output level. The range of compression is 16 dB. If the input is driven more than 16 dB over the threshold, the portion of the signal over 16 dB will be passed linearly. At that point, the next limit to output will be amplifier clipping. (See Figure 2.9 for a table of potentiometer settings and the corresponding voltage and power outputs from the amplifier.)

H. Compressor Control

This two-position jumper block controls the feedback path that will drive the compressors. The compressor in a certain channel can be controlled by the error amplifier of that channel, the error amplifier of the other channel, or neither (compressor turned off). When the compressor is turned off, no amplifier condition, whether it is high output voltage or clipping, will cause the compressor to activate. To turn the compressor off, place the jumper on only one pin of the jumper block.

I. Daisy Output Jumpers

These two-position jumpers are used to select between sending the processed signal (NORM) and the unprocessed signal (BYPASS) to the daisy chain outputs. Sending the processed signal to the daisy chain outputs will allow two or more amplifiers to run off of the same processed signal, so only one P.I.P.-BP1 would have to be used (the signal needs only to be processed once for all of the amplifiers that need the signal). Sending the unprocessed signal to the daisy chain outputs will enable the use of other P.I.P.-BP1 modules with different DIP switch settings or the use of other P.I.P. modules to perform different functions on the same input signal. Both jumpers of each channel must be in the same position for correct operation.

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 0.1×F capacitor.

3 Installation

To avoid damaging the P.I.P.-BP1 turn off the amplifier's power before making any changes (the P.I.P.-EXTaccessory 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 non-inverting ("hot"), and pin 3 is inverting. (Figures 3.1 and 3.2 illustrate this.)

Fig. 3.2 Unbalanced Input Wiring

The P.I.P.-BP1C, comes supplied with removable barrier block connectors. These connectors are wired with pin 1 non-inverting ("hot"), pin 2 ground and pin 3 inverting. (See Figure 3.3.) Matting barrier block connectors are supplied with the unit that are used to attach to the interconnecting cables. The barrier block connectors can then be connected and disconnected easily.

Fig. 3.3 Audio Wiring

Some Crown amplifiers come supplied with permanent 1/4-inch input jacks. These should not be used for input while the P.I.P.-BP1, is installed but they may be used as unbalanced daisy chain outputs with loads greater than 5 k ohms. If used in this manner, the signal available at each jack will be the channel output signal from the PIP. This signal is the same signal that is sent to the amplifier to which the PIP is connected. This provides another way to have several amplifiers track the signal that one P.I.P.-BP1 produces. (Another is to use the daisy chain outputs of the PIP.)

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. Turn down the level controls (full counterclockwise), turn off the amplifier and unplug it from the AC power source.

  2. Remove the existing PIP module or panel (two screws). For PIP2 amplifiers, this may involve disconnecting the PIP from a PIP2 input adapter (see Figures 3.5 and 3.6). If a PIP2 input adapter is already present do not remove the ribbon cables from the adapter. Otherwise you will have to reconnect them in the next step.

input cables of the amplifier (see Figure 3.5). Notice that the PIP2 input adapter should be positioned with the PIP edge connector on top and facing away from the amplifier. The 20-pin cable (A) is connected first, then the 18-pin cable (B) is connected. Both ribbon cables should extend below the PIP2 input adapter.

Next, insert the edge connector of the P.I.P.-BP1 into the PIP2 input adapter (see Figure 3.6) and insert the assembly into the PIP opening in the back of the amplifier.

  1. Tighten the two PIP mounting screws.
  2. Connect input and output wiring as described in the preceding section (Input/Output Wiring).
  3. Plug in the amplifier and turn it on. Adjust its level controls to a desired setting. (In Dual mode, the level controls can now be used to balance the low and high frequencies.)

Do not tamper with the circuitry. Circuit changes made by unauthorized personnel, or unauthorized circuit modifications are not allowed.

Remember: Crown is not liable for any damage resulting from overdriving other components in your sound system.
