Before you start your nstallat on
We recommend that a fuse or circuit breaker be placed within 18" of the battery.
Althou h you will add a fuse or fuse block near the amplifier it is still a possibility that a
pinched power wire between the component fuse and the battery could result in a short,
or even a fire. The protection device should be placed where it can be accessed easily
and all wirin should be routed safely and correctly accordin to the followin uidelines:
• Do not run wirin close to hot or spinnin objects.
• Use wire rommets when routin wire throu h the firewall or any other metal panels
• Make sure that the potential for pinched wirin is avoided by routin all wires away
from movin objects, includin brake, as and clutch pedals, etc.
Plann ng your power connect ons
The power end plate has the main 12-volt power input, the 12-volt turn-on wire, and the
main Ground connection.
• The 12-volt power input must be connected the vehicle battery's positive (+)
terminal, and a main system fuse should be placed close to the battery.
• The Ground connection must be securely attached to bare metal at the vehicle
frame, or other heavy chassis component with a direct connection to the frame.
Note: Seat bolts and seat belt bolts are NOT good ground po nts
• The REM In input can be connected to the head unit turn-on output wire.
If none is available it can be connected to an accessory (ACC) terminal. You should
avoid usin any i nition-on (IGN) wire, as they can be noisy.
Mount ng your un t
Mountin your unit is easy. Just keep in mind a few uidelines:
• The unit can be mounted in any direction, on wood, metal, or carpet but not upside
down as heat rises and will build up if it is mounted upside down.
• The metal chassis of the amp can be rounded or left isolated.
• The amplifier requires adequate ventilation. Creatin power creates heat, and
coolin requires air. Position the amplifier with sufficient surroundin area for air
supply and keep the end plates clear for future access.
• Keep the unit out of the en ine compartment or other locations that may cause
excessive heat or moisture.
• Do not mount the unit to places that may have excessive vibration.

PC Control Program
The Control Pro ram requires no installation. Just download the file from the Harmony
website an put it on your desktop. You should check back on the site re ularly to assure
you have the most up-to-date version of the software. Below is the layout of the main
screen, as you open the software.
Ma n Screen
Here are all the functions on the main screen.
1 - At the very top of the GUI there is the F le Menu (Pa . 8). The Preset button is
where you will save setups to memory presets and load setups from those saved.
Option let you choose Lan ua e and other tools like BT/USB volume. The Mix
button opens the I/O Matrix screen, where you can manually determine which
inputs will be used for each output and how much of each input the output will
receive. Encrypt is where you mana e your password.
2 - Here you choose the Input you will use while tunin . You can choose AUX which
can be an aftermarket head unit, or a factory head unit usin the HI-LEV option.
You also have USB and BT (Bluetooth) input if you add the optional module.
3 - Connection status.
4- H gh-Pass and Low-Pass F lter for each channel. You can type in the frequencies
and choose crossover style and slope or turn the crossovers off, if you do not want
them for some channels. Always check the speaker makers recommendations for
crossovers before you make the crossover decisions.
5 - EQ area. Here are 15-bands of parametric equalization for each output channel
and you can vary Frequency, Gain, and Q (the shape of the adjustment) for each
band. Frequency: Each band is numbered. You can simply click onto a band button
and dra it to where you want it. When you click onto a band there is a “Heads-up
display” of the Frequency, Gain, and Q of the band.
6 - Here you find the master level control.
7- The Output Channels section is for Speaker Assi nment, Delay, adjustin Levels and
checkin Polarity to be sure all speakers are in phase with each other. There are a
number of systems for checkin System Phase. If the systems speakers are not
all in phase there will be issues you can not fix by tunin . You can see the section
on System Phasin (Pa . 8) to see one method of Phase checkin . The MUTE
buttons allow you to turn off any speakers that you do not want to hear while you
are tunin other speakers. The purpose of Delay is to make every speaker the
same distance from you, so you are in the middle.
8 - Here you choose between GEQ (Graph c) and PEQ (Parametr c) equalizers, or
Reset EQ, if you want to reset channels to default positions with no equalization.
9 - Here you Reset, Link or Lock Output Channels.

F le Menu
At the very top of the GUI there is the File Menu. The Preset button is where you will save
setups to memory presets and load setups from those saved. Here you can also save
setups into your PC. Opt on button let you choose between Lan ua es, Noise Reduction,
Reset function, Input volume, and informations about your device and software. MIX will
open the I/O Matrix screen (see below). With Encrypt you can mana e your Password.
I/O Matr x
With the Mixin Set, you can manually determine which inputs will be used for each output
(processin channel) and how much of each input the output will receive. The inputs are
listed down the left side and the output channels are listed across the bottom.
System Phas ng
Before equalization you should assure that all speakers are in phase as a system at the
listenin position. All speakers need to have the same polarity so they move the same
direction at the same time. If they are not, you will not be able to et a proper tune.
There are a number of methods for doin this. We offer one.
Tweeters (A): Mute all speakers except the tweeters and play a hi h female vocal solist.
You should hear the voice at a sin le point near upper middle of the windshield. If the
speakers are out of phase the voice will not be localized but will seem to come from
everywhere. To test, usin the Phase buttons, chan e the phase of the ri ht speaker and
listen for the difference. Do this a couple of times as needed. The position that puts the
voice in a small sin le location on the window is the correct phase.
Tweeters (B): Note where the Tweeter center is located. It should be just sli htly above
and to the left of the center of the windshield (for left hand drive cars). If it is off to the
opposite side of center or too far to the left, and if you have measured correctly, then you
have a ain difference and you can correct by a sli ht level adjustment reduce the ri ht
tweeter to brin it left or reduce the left channel to take it ri ht. No more that 1dB or
2dB. Now the tweeters are set. From here on out you cannot chan e the levels or phase
of either tweeter.
M ds, M d-Woofers, and Subs: Now mute the tweeters and un-mute the midran es.
The process is the same for each pair of speakers. The sound should come from a sin le
focused point near the center of the windshield. For midran es and lar er drivers, you
want to use a deeper male vocal. The lar er drivers are much easier to tell the differences
between in-phase and out of phase. Also, with the lar er speakers you will hear a dramatic
reduction of bass if the speakers are out of phase. So, for midran e and lar er speakers
you will look for a focused sound source in the windshield with stron er bass.
NOTE: Once each channel pa r s adjusted, they cannot be separated. Any change of phase must be
done by the pa r.
Phas ng the pa rs: A ain, listenin to a sin le vocalist. Mute all channels a ain except
the tweeters. Then brin in the midran es. If these pairs are in proper phase the sound
should be near center in the upper part of the windshield. If they are not in phase the
sound will be pulled down lower. You can reverse the phase of BOTH mids now and
listen for the difference in the sound location. Choose the phase position that puts the
sound hi h near the center.
Once you have these phased you can brin in the mid-bass with the same process. A ain,
the focus should be hi h in the dash. If the mid-bass is out of phase with the tweeters
and mids then they will pull the sound down toward the floor.
Woofers or Subs: There will be bass! You have phased the woofers, so we know there
will be bass. What you need to listen for here is location, and mid-bass (somethin with
kick drums is ideal). Proper woofer phasin will work with the mid-bass drivers to ive
ood solid, crisp mid-bass. Out of phase will result in a soft, low-impact mid-bass. Bass
out of phase with the mid-bass will also be more located in the back of the vehicle while a
properly phased bass will blend better into the front soundsta e.

Mob le Control Program (APP)
Just download the APP from the Harmony website or iOS/Android store. The oal is to
have a control system that made sense in a smaller platform but would allow the user to
do everythin necessary for a complete setup and tune with a smartphone or tablet.
Turn on your unit and connect the ext. BT module. It will enter into pairin mode with blue
li ht flash alternately. Open the Bluetooth of your smart device and search the DSP for
pairin . Red BT icon means not connected.
