Mounting
MOUNTING
To prevent damage to the
PAR-245
while driving, mount it in a
secure place. Choosing the appropriate location will depend
upon your vehicle and the complexity of your system design. Typical
mounting locations for your new
PAR-245
would be in the dash or
center console. Never mount the component in a location that would
subject it to immersion or exposure to water.
Once a location has been chosen, securely mount the
P AR-245
using
the two supplied brackets. There are two different sets of brackets
included with your
245
, as shown above. The other set is used to surface mount, as
P AR-245
. One set is used to flush mount the
P AR-
shown on the next page. The brackets are connected to the equalizer/
preamp by two 6-32 x 1/4" socket head cap screws. We have made
the brackets adjustable to compensate for the uniqueness of each
vehicle. Be Careful! Inspect the area underneath to be sure you are
not drilling into wires, etc. that could be damaged by the drill bit or
screws.

NOTE
Before beginning, disconnect the negative (-) terminal of the
battery prior to working on the positive (+) terminal to prevent
a short to ground. This is important, unless you want to spend
the rest of your life with a nickname like
"Sparky ,"
or
"Smokey."
Reconnect the negative terminal only after all connections have
been made.

WIRING
The next step is to connect the Power , Ground, and Remote wires to
your
PAR-245
. The power wire should run from the mounting location
through the vehicle to the battery or power distribution block. Avoid
sharp corners, creases, and sharp body parts. When passing through
any metal wall (i.e. firewall etc.), a grommet must be used to prevent
the wire from chaffing and shorting to ground.
The ground wire should be of the same gauge as the power wire. As
a rule of thumb, use as short a length of wire as possible.
Find a location near the equalizer that is metal (the floor is ideal) and
clean an area about the size of a quarter to bare metal. Drill a pilot
hole in the middle of this area. Be Careful! Inspect the area underneath
to be sure you are not drilling into wires, brake or fuel lines, etc.
Terminate the wire with a ring connector and attach it to the bare
metal using a #8 sheet metal screw and washer (not supplied). We
suggest crimping and/or soldering this connection. After the connection
is complete, coat the area with silicone or some similar material to
prevent rust from developing.
Finally, the remote wire needs to
run to the power antenna (or
Powerlock
Ground
Remote
Powe
amplifier remote) lead of the head
unit. This wire supplies a 12 volt
signal to the
PAR-245
when the
T/O
B+
main system is activated.
Once you have routed the power ,
ground, and remote wires through
the vehicle, it is time to connect the wires to the
PAR-245
. Be sure
that you have not reconnected the ground cable to the negative post
of the battery.
Cut off excess wire and, using wire strippers, strip the power , ground
and remote cables about 1/8 inch. Locate the power, ground, and
remote
Powerlock
connector (supplied). On the top of the connector
are three slotted screws. With a small flat-bladed screwdriver , loosen
the screws before attempting to insert the cables. After you have
inserted the stripped end of each cable into the connector, secure it
by tightening the associated screw. Check that each connection is
tight. If the wires are secure, the connector may be plugged into the
PAR-245
.

SYSTEM TUNING
System Gain Adjustment
In order to achieve maximum signal-to-noise performance from
a high quality auto stereo system, it is desirable to use high
signal levels wherever possible in the interconnect cables. High signal
levels will reduce the effect of induced noise. The peak level of an
audio signal is usually determined by the clipping level of electronic
components. The following procedure should be used as a guide
before the system installation is completed.
Adjustment of source unit output and
1. Turn

2. Turn source unit volume 1/2 to 3/4 of maximum.
3. Adjust all
PAR-245
input gains fully counterclockwise.
4. Play a CD or cassette. A loud music selection is desired.
5. Adjust the left input gain control clockwise until the
input clip LED lights. Then adjust the control
counterclockwise slightly until the LED doesn't light. This
setting will minimize system background noise and
prevents overloading the

There are separate left and right gain adjustments
for each input which allows left/right balance

SYSTEM TUNING
Parametric Operation
The
PAR-245
Equalizer/Preamp puts an incredible amount of
control at your fingertips. Correctly adjusted, it can solve many
of the problems you will encounter along your road to perfect sound.
By following these guidelines, you will avoid common pitfalls in system
tuning and get your sound quickly dialed in. We recommend that you
use a Real T ime Analyzer (RTA) to speed things up, but it is possible
to tune your system without it.
It is important to understand what your equalizer actually controls to
be able to use it effectively . On the face of the
P AR-245
are five Boost/
Cut controls each corresponding to a range of frequencies. On the
top are the five sets of Frequency/Q Selection switches to adjust for
each Boost/Cut control on the front of the
PAR-245
(See the chart on
pages 14 and 15 for Frequency/Q selection.)
Q is an indication of how wide or narrow the adjusted bandwidth is. A
low Q will affect a wide range of frequencies around the selected
center frequency resulting in a gently curved shape, while a high Q
affects a narrow band resulting in a peaked shape as shown below.

BA CK TO CONTENTS
SYSTEM TUNING
NOTE:
If you are using the
(like the
DEQ-230
or
PMQ-210
PAR-245
as well as another equalizer
) Go to step 11.
1) The first step is to locate a suitable source of “pink noise." A
good choice would be the current IASCA competition reference
disc. Also, some RTAs have a built-in pink noise source. Ideally,
the pink noise should play through your head unit, allowing you to
compensate for any frequency response changes caused by it, or
anything else, before the amplifiers.
2) Next, place the microphone from the RTA in the driver's seat at
approximately head level. Initially, set the analyzer to read at 3dB
per step, and set the speed of the RTA’s readout to medium. Turn
on your system and start the pink noise. Raise or lower the volume
until you can see all (or most) of your frequency response on the
RTA scale (a little above or below is OK). Make sure all of the
equalizer's frequency controls are centered and look at the RTA
screen.
3) Y ou are trying to achieve a target frequency response, or "curve"
that reflects your preference. Y ou might think that a perfectly straight
line would be best, but it really doesn't sound very good. Instead,
shoot for a curve that starts about 9 dB up at the low frequencies (25
Hz to about 100 Hz) dropping gently to 0 dB in the midrange (250
Hz to 3 kHz), then dropping gently to -9 dB at 16 kHz and 20 kHz.

4) If electronic crossovers are used, any large frequency sections
corresponding to your crossover points that are low or high should
be brought in line using crossover level controls or amp gain
adjustments rather than the equalizer.
5) To begin, you will probably see several peaks and dips in your
RTA curve. Find the lowest offending frequency, and choose the
appropriate frequency range control on the top of the
PAR-245
.
Reading from left to right when looking at the face of your new
PAR-245
, the following are the frequency ranges;
BAND FREQUENCY
SUB 30 Hz - 66 Hz
LOW 90 Hz - 300 Hz
LOW-MID 430 Hz - 900 Hz
HIGH-MID 960 Hz - 4.6 kHz
TREBLE 6 kHz - 16 kHz
6) Looking at the Frequency/Q selection chart for the selected band,
set the switches on top of the
P AR-245
to the frequency that is closest
to the peak (or dip) and has the highest Q. T urn the Boost/Cut control
counterclockwise until the peak (clockwise to correct a dip) comes in
line with your desired curve. (See pages 14 & 15.)
7) When the center frequency of the original peak (or dip) has been
brought down to where you want it, you may see that surrounding
frequencies are still higher than you want them. Select the closest
frequency to the original peak (or dip) that has a lower Q, and see if
you now have a smooth line through that band. You may have to try a
number of Frequency/Q combinations to get the best results.
11

8) Move to the next peak or dip, and repeat the process until you run
out of frequencies to adjust. Try to remove the peaks before filling the
dips. Periodically , while you are making adjustments, compare the new
curve you are making to the system in an unequalized state by using
the defeat switch on the front face plate of the
PAR-245
.

9) Play your favorite music. If the sound isn't what you're looking for,
go back to the pink noise and smoothly adjust your curve for more
bass, less midrange or whatever you think will correct the sound.
Remember that this is your system - don't let someone else tell you
how it should sound! When the sound is close to what you want, move
to step 10.
10) Play several different music tracks. If you hear an instrument, voice,
or other sound that is too loud, find the sound on the chart on page 14.
This will give you clues as to what frequencies need to be adjusted on
the
PAR-245
. (If you have already tuned using an RTA, this step is
icing on the cake.) Make one adjustment at a time, giving yourself
time to notice the changes.
11) If you are using another equalizer, like the
PMQ-210
using the other equalizer . This leaves the

PAR-245

frequency adjustments, compensating for equalization differences
between Radio, Cassette, Video and Digital sources, like DAT and
CD. Select Frequency/Q combinations for each band near the center
