SAFETY INSTRUCTIONS
◼Do not turn on any function which may distract you while driving the vehicle.
Functions requiring sustained attention must only be used when the vehicle is at a
complete standstill. Make sure to always stop your vehicle in a safe place before
operating these functions. There is a risk of causing an accident.
◼Keep the volume at a low level to be able to hear exterior noises while driving
the vehicle. There is a risk of causing an accident.
◼Do not open the amplifier or undertake any modification of the product. There
is a risk of accident, fire or electric shock.
◼Only use this amplifier with 12V mobile applications. Any other use other than
the use for which this product has been designed may lead to fire, electric shock or
injury.
◼Use fuses of the correct amperage. There is a risk of fire or electrocution.
◼Do not obstruct radiators and/or vents. Internal overheating may occur and cause
a fire.
◼Ensure all connections are properly made. Check the section of cable and the
type of cable if it does not correspond with the use. There is a risk of fire, injury and/
or damage to the product.
◼Do not use nuts or fasteners part of the steering or braking systems for ground
connection. The fasteners and nuts used for the brake and steering systems (or any
other security system) as well as various tanks must never be used for grounding.
Use of these parts as ground may deactivate the vehicle’s control system and cause
a fire or other technical problem.
◼Keep all small objects which could be swallowed, such as the fasteners and
screws, out of the reach of children. Swallowing such objects may cause serious
injuries. In the event of swallowing any of these objects, immediately seek medical
advice.
◼Before starting the installation, disconnect the negative terminal of the battery
to avoid any risk of injury, fire or damage to the equipment.

MOUNTING INSTRUCTIONS
1. Before you start with the installation, make sure you know the security code of your
headunit (if applicable).
2. Remove the headunit from the dashboard and disconnect the main wire.
3. Find a place for the AMP-RAV4-16-18 and connect the provided (or optionally
available car-specific) wire to the amp.
4. AMP-RAV4-16-18 only: For more power output please follow these steps: Run a 10
mm2 power wire from the (+) pole of the battery to the (BATT) terminal of theamplifier.
Use a fuse with the related value of the cross section of the power wire. The distance
between the B+ pole and the fuse holder must be 30 cm or less. Run the minus cable
with the same cross section from the (GND) terminal of the amp to the vehicle chassis
ground. Make sure that the contact surface is clean in order to get best conductance.
5. Connect the wire to the headunit.
6. Install the headunit back in the dashboard.

WIRING DIAGRAMAMP-RAV4-16-18
If you want to use just the DSP function of the AMP-RAV4-16-18 with a separate high performance amplifier,
connect the line out of the AMP-RAV4-16-18 with the RCA input of your amplifier.

1* In some cases with old headunits the Auto-Turn-On function cannot work. If you meet this problem, please
just put the separately provided wire “ACC-IN” into the connector of the connection cable and connect it to
ACC/Amp Remote of the car stereo or another cable which will provide +12 V only when the car stereo is
turned on. Secondly select “REMOTE TURN ON” on the remote switch.
2* REM-Out: Connect this wire to the remote input of a separate amplifier, for example a mono amp for a
subwoofer.

EQ Settings
In the EQ menu you can build your sound
according to your settings. Depending on
the grade of required accuracy, you can
chose between a 10 and a 31 band para-
metric equalizer.
Swipe to the right/ to the left to get to the
bands outside of the screen area.
If required, you can choose independent
equalizer preferences for the front and
rear channels and even for each channel
separately. Simply use the slider Front or
Rear. When you want to do one setting for
all channels (w/o sub) just press the “all”
button .
To reset all settings to „0“, press the
„Reset“ button in the EQ menu. If
you just want to try out the presets and
then go back to your personal preferences,
exit without saving the app, and then
restart. The app will then load your saved
preferences from the amplifier.
In the line „f0“ tap on the band you want to
adjust. A pop-up window appears to enter
the value of the center frequency you want.
Confirm with „Ok“ .
In the line „Q“ tap on the band you want to
adjust. A pop-up window appears to enter
the value of the quality factor you want.
Confirm with „Ok“ . Instead you can
also touch “-“ or “+” to adjust the Q factor in
0.1 steps.
The quality factor (Q factor) determines the
effect of the EQ filter (bandwidth) on the
frequency band around the chosen center
frequency f0.
Example1: f0 = 1000 Hz
desired bandwidth of EQ filter = 1000 Hz
(i.e. 500 Hz –1500 Hz) Q = 1
Example2: f0 = 1000 Hz
desired bandwidth of EQ filter = 200 Hz
(i.e. 900 Hz –1100 Hz) Q = 5
Q factors from 0.3 to 9.9 are possible.
Dynamic Bass
Located in the EQ menu, the “Bass” slider
is a very effective way to increase bass per-
formance without overloading the speakers.
Level at “0” = no Dynamic Bass function
active.
Level at “1” to “20” = the higher the value
the higher the bass increasing. Simulta-
neously a strong subsonic filter is enabled
to protect the speakers from deepest bass
frequencies to avoid damage to them.

Gain Phase
Gain Phase
In this menu you can make the following
settings for each individual channel: sound
level, mute and phase. The sound level set-
tings are made in the field above and under
the respective speaker icons.
In the lower area of the menu in the top line
are the icons for setting the phase. From
left to right: Front left, Front right, Rear left,

your smartphone. Todo this, press „Save
on Phone“ , and enter the desired
filename.
Noise Gate
In the upper right corner of the GAIN menu
you can find the Noise Gate function. It’s a
dedicated to reduce the back ground noise
of the head unit. If back ground noise of
the head unit is audible, increase the Noise
Gate level by sliding to the left until you
cannot listen the noise anymore.

Crossover
In this menu you can assign a frequency
band to the connected speakers that cor-
responds to their recommended operat-
ing range. You can chose to adjust each
channel separately, combine front and rear
speakers and also all speakers together.
In the left half of the diagram you can set
the break frequency of the high pass filter
as well as its slope. In the right half are the
break frequency and slope of the low pass
filter. The blue line shows the set slope of
the filter. „Bypass“ means that the signal is
unfiltered and contains all frequencies.
The filter settings also apply to the corre-
sponding preamp outputs.
When you have done all settings, go back
to the main menu, and touch the „Save
to Amplifier“ button to transferthe
settings to the amplifier. During the saving
process do not switch off the amplifier as
this may lead to malfunction and/or dam-
age. You can also save the settings on your
smartphone. To do this, press the „Save on
Phone“ button , and enter the desired
filename.

(FL) front left is 0.80 m from the listening position
(FR) front right is 1.40 m from the listening position
(RL) rear left is 0.50 m from the listening position
(RR) rear right is 1.30 m from the listening position
(SubW) subwoofer is 2.00 m from the listening position
Value for FL = SubW –FL → FL = 2.00 – 0.80 m
Value for FR = SubW –FR → FL = 2.00 – 1.40 m
Value for RL = SubW –RL → RL = 2.00 – 0.50 m
Value for RR = SubW –RR → RR = 2.00 – 1.30 m
SubW remains at the value „0“
Time Alignment
Press the „Time Alignment“ button to go
to the menu. In this menu you can apply a
time delay to the speaker signal to simulate
an ideal listening position. Note the
distance between your listening position
and each speaker. Choose the most distant
speaker as the reference for the other
speakers.
Note the distance
between your
