P.I.P.-XOV

1 Welcome

Thank you for purchasing the

Crown

P.I.P.®-XOV

accessory.

PIPTM

modules are designed to

quickly install in the rear panel

of many Crown amplifiers. PIP

stands for “Programmable Input

Processor.” Their versatile fea-

tures 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. It provides

high-pass and low-pass filters

with 18 dB/octave (3rd order)

slopes for bi-amp and tri-amp

systems.

Five two-position sliding switches

make it easy for the user to se-

lect one of twenty-four modes of

operation.

Plug-in resistor and capacitors

make it easy to change the cross-

over frequencies.

D. Mode Switches

Five slide switches (S1–S5) are

used to configure the P.I.P.-XOV

in any of its 24 different modes

of operation. Each switch has

two positions: A (up) and B

(down). See the table in Figure

3.1 for a description of each

mode and their respective

switch settings.

E. User-Replaceable

Components

Six resistors (R1–R6) and six ca-

pacitors (C1–C6) can be easily

unplugged and replaced with

components of different values

to change both the crossover

frequency and the response

curve (Bessel, Butterworth, or

Chebyshev).

2 Facilities

A. Thumb Screws

Use these two thumb screws to fas-

ten 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 out-

put of the P.I.P.-XOV. Each phone

jack is parallel to its XLR connec-

tor counterpart.

C. XLR Connectors

A balanced 3-pin XLR connector is

provided at both the input and out-

put. A female connector is used for

the input and a male connector is

used for the output. These connec-

tors are wired with pin 2 high and

are parallel to their phone jack

counterparts.

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. 2, unprocessed sig-

nal to the output connectors for

daisy-chaining.

• Mode 5: Low-pass to Ch. 1, high-

pass to Ch. 2, unprocessed sig-

nal to the output connectors for

daisy-chaining.

• Mode 16: Band-pass to Ch. 1 for

mono operation, with unproc-

essed signal to the output con-

nectors for daisy-chaining.

• Mode 20: High-pass to Ch. 1 for

mono operation, with low-pass

signal routed to the output con-

nectors.

• Mode 22: Low-pass to Ch. 1 for

mono operation, with high-pass

signal routed to the output con-

nectors.

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-

ALLEL-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.

Diagrams illustrating the connec-

tion of each mode are included in

Appendix A to assist your selection.

Crossover Selection

The P.I.P.-XOV is factory-set for

a crossover frequency of 800 Hz

with a Butterworth response. In-

cluded with the PIP are additional

resistors to change the crossover

frequency to 100 or 500 Hz, and

capacitors to change it to 1, 5 or

8 kHz.

Changing the filter type or its

crossover frequency is simply a

matter of plugging in resistors

and capacitors of the desired val-

ues. Six resistors and six capaci-

tors are socketed for this purpose

(Figure 2.1).

Three filter types are available:

Bessel, Butterworth, and

Chebyshev. Each differs in its

ability to provide ideal frequency

response, a constant signal de-

lay, and large stopband attenua-

tion. A brief description of each

type follows:

B e s s e l

A Bessel filter provides minimum

phase distortion throughout its

passband (i.e. the most constant

signal delay), which is desirable

for pulse-type waveforms, but has

the poorest stopband attenuation

of the three filter types.

B u t t e r w o r t h

A Butterworth filter provides the

flattest response in the passband

with a moderate amount of

stopband attenuation. This filter is

most commonly used in crossover

applications.

C h e b y s h e v

A Chebyshev filter has more at-

tenuation in the stopband at the ex-

pense of ripple in the passband.

For example, a 0.5 dB Chebyshev

filter has attenuation varying from

0 dB to 0.5 dB in the passband,

but has attenuation in the stopband

greater than that of the other two

filter types.

P.I.P.-XOV

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. Resistors R1–R5

should always be greater than 2 K

ohms and less than 330 K ohms.

Resistor R6 should always be less

than 1 M ohm. The value of ca-

pacitors C4, C5 and C6 can be

any arbitrary value so long as it

allows R1–R6 to meet the above

criteria.

All resistors should have a 1% tol-

erance and should be rated for

0.25 watt. All capacitors should

have a 10% tolerance and be of

the film type.

Fig. 3.3 Butterworth Filters

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

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 0.01 x 10E–6) = 4,563 ohms.

R6 = (1 / 0.1109) / (2 x 3.14159 x

400 x 0.01 x 10E–6) = 358,800

ohms.

The 1% precision resistors with the

closest values are: R4=19.6 K

ohms, R5=4,640 ohms, and

R6=357 K ohms.

Figure 3.3 lists the resistor and ca-

pacitor values for a Butterworth fil-

ter using K1=1.392, K2=3.546, and

K3=0.2024:

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 cir-

cuitry while the amp is plugged

in. Even though the amplifier is

off, there could still be enough

energy remaining to cause elec-

tric 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

PIP2TM

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.

Standard PIP Amplifiers

: Align the

edges of the P.I.P.–XOV

in the PIP

card rails and firmly push the unit in

until it is seated against the

mounting bracket (see Figure 3.4).

PIP2 Amplifiers:

(Requires a PIP2

input adapter. Crown part number

Q43528-1.) Connect the PIP2 input

adapter to the two 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.–XOV into the PIP2 input

adapter (see Figure 3.6) and insert

the assembly into the PIP

opening in

the back of the amplifier.

4. Secure the P.I.P.–XOV

with the two

screws and lock washers provided.

(The lock washers are important

because they bond the PIP 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.Circuit

changes made by unauthorized per-

sonnel, or unauthorized circuit modifi-

cations are not allowed.
