OPERATING / SERVICE MANUAL

FPE 13

PARAMETRIC EQUALIZER

QUICK START

No one likes to read manuals. Everyone likes to plug in and turn on. That’s usually OK, and

with a very few exceptions, damage is unlikely to result from such procedures with the FPE 13.

If you are using the FPE 13 in an insert loop of a mixer, hook-up is extremely easy. Simply

connect them together using a single stereo cable (¼" TRS) between the mixer’s insert loop and
the FPE 13’s 

PATCH I/O

 jack. This jack is wired for the tip=send, ring=return convention used

by mixer manufacturers.

Anyone familiar with other parametric equalizers will find this one very similar. One word

of caution: the 

FREQ

 

range

 switches can drastically change the center frequency of a given

filter. A range of 10Hz to 20kHz may be achieved with the proper operation of the switches and
the 

FREQ sweep

 control. If full boost is applied with a filter 

LEVEL

 control and a change is

made in the setting of the 

FREQ range

 switch, disastrous results may occur. 

BE CAREFUL

.

To operate the filters, set the range switch for the desired mulitple frequency band, set the

BW

 (bandwidth) control for the desired bandwidth and then boost or cut the desired amount

using the filter 

LEVEL

 control.

 This is an AC input and requires special

attention if you do not have an operational power supply 

exactly

 like the one that was originally

packed with your unit. See the full explanation of the power supply requirements elsewhere in
this manual.

SYSTEM CONNECTION

When connecting the FPE 13 to other components in your

system for the first time, 

leave the power supply for last

. This

will give you a chance to make mistakes and correct them
before any damage is done to your fragile speakers, ears and
nerves.

INPUTS

 on the FPE 13 are balanced. This means that

standard 3-pin (XLR) connectors on the ends of any good
quality cable will work well between your other signal
processing and amplification gear. As with all Rane products,
pin 2 is used for “hot” or “+” signal polarity, pin 3 is “return”
or “–” and pin 1 is signal ground. If unbalanced operation is
required, wire your connector so that pins 1 and 3 are shorted
together and drive your unbalanced signal into pin 2. Then
use the combination of 1 and 3 for signal ground/return. You
may use either pin 1 or case for shield ground. (See Rane
Note 110 for further information on this subject).

OUTPUTS.

 The FPE 13’s Outputs are balanced as well.

Again, pin 2 is hot and pin 3 is not. Pin 1 is signal ground.
True balanced operation requires only the use of pins 2 and 3
for signal and either case ground (chassis) or pin 1 signal
ground for shielding. If unbalanced output is your preference,
use pin 2 as signal and pin 1 as return. Use case ground for
shield. Again, have a look at Rane Note 110 for more detail.

EXPANDING

 the Inputs and

Outputs has been accommodated
with ¼" jacks whose tip is connected
to pin 2 of the 3-pin connectors, ring
is connected to pin 3 and sleeve is
connected to pin 1. These ¼" jacks
may be used for primary Inputs and
Outputs should you wish to do so.
These connectors may also be used
for daisychaining the Inputs so more
than one processor can be driven from a single source, but
only 

one

 is an Input; they do not sum. The second Output

connector may be used to drive a second processor or
amplifier without special cabling.

PATCH I/O

 to channel inserts on most mixers has been

made very simple. Connecting a shielded stereo tip-ring-
sleeve (TRS) cable between the FPE 13’s PATCH I/O and a
TRS insert on your console implements this feature.

SIGNAL LEVELS

 applied to the FPE 13 may cover a

broad dynamic range. This device has been optimized to
operate perfectly with all signal processing and amplification
gear. The only signal level problems encountered will be with
very low level sources, such as microphones. Do not directly
connect mic levels into the FPE 13. Use a mic preamp first.
