plethora of sound advice, and help set the mood for the installation.

1. The following details give a brief overview of the steps required
to install the DM-608/DM-810 in your system. The steps below
are explained in more detail throughout this manual.

2. Undo the +12V and Ground connections to the car battery
before making any connections to the DM-608/DM-810.

3. When making connections, designate red RCA plugs as right,
and designate white, black, or grey plugs as left.

4. Use quality interconnect cables. We know from experience that
really cheap cables can cause a multitude of problems.

5. Connect the +12V input terminal of the unit to the +12V termi­nal of the vehicle battery.

6. Connect the Ground terminal of the unit to the negative termi­nal of the vehicle battery.

7. Connect the remote power terminal of the unit to the remote
turn-on switch of your source unit. Alternatively, you can skip
this connection and use the GTO Signal sensing on inputs 1-2.

8. Connect your audio inputs to the unit – either speaker-level or
line-level RCA.

9. Run the optional ACR-3 remote to the front of the vehicle to
adjust the level on the y.

10. Note that the following setting up is carefully done with the
ampliers turned o (or not connected), to help prevent tweeter
damage (for example) during the DM-608/DM-810 setup.

11. When you are satised that all is looking good and correct,
reconnect the vehicle battery. Make sure the ampliers are o.

12. Install the control application onto your computer, but make
sure that the computer is not connected to the unit during the
installation.

Installation Manual

Chapter 4: Installation

Installation

We recommend mounting the DM-608/DM-810 in the trunk/boot or
cargo area of the vehicle. An alternative location would be under the
front seat of your vehicle if there is enough room to install and also
to reach the controls. When choosing a location, please keep these
things in mind:

1. Before you start, disconnect the +12V positive and negative
cables from the battery in the vehicle to prevent any damage to
the vehicle or the amplier during the installation process.

2. Pick a mounting location that will provide access to the controls
and connections, provide adequate ventilation, and also protect
the unit from heat, moisture, and dirt.

3. The DM-608/DM-810 needs to be securely mounted using the
four mounting holes located in each corner.

4. Before drilling any holes, take every precaution to prevent dam­age to fuel lines, power and other electrical wiring, hydraulic
brake lines, and other systems, that might compromise vehicle
safety.

5. Always mount the unit as far from the antenna in the vehicle
as possible, and away from the radio or any other RF sensitive
electronics in the vehicle.

6. Use a sucient-gauge insulated power cable with a 3 Amp in­line fuse, to connect the +12V terminal of the DM-608/DM-810
to the positive terminal of the vehicle battery.

7. Use a sucient-gauge insulated cable to connect the ground
terminal of the DM-608/DM-810 to the negative terminal of the
vehicle battery.

8. The DM-608/DM-810 has speaker-level inputs that are designed
to accept amplied, speaker-level signals from a factory source
unit or amplier. You may need to refer to a factory service man­ual or wiring-harness schematic to determine which wires are
the speaker wires for your system. If you are unsure which are
the speaker wires, we recommend you look at the color of the
speaker wires connected to the speakers and follow them back
to the source. Connect the speaker wires to the DM-608/DM-810
speaker-level input plugs using the correct polarity.

9. Line-level audio signals will generally come from your after­market radio, or if you are really getting the most out of your
car audio system they may be coming from a really awesome
product like the AudioControl LC6i (shameless plug). There are
generally only two things to consider when using the line-level
RCA inputs: 1. Use good shielded or twisted pair RCA cables and

2. Run your RCA cables at least 18” away from power and speaker
cables to avoid picking up radiated noise in your system.

Chapter 4: Installation

ACR-3 Dash Control Installation

The optional AudioControl ACR-3
dash control is a dual-function remote
for your DM-608/DM-810. It may be
mounted under the dash using its own
bracket, or through a custom hole in
the dash. The endless knob should
be within reach of the driver, and in a
spot where the two LEDs are plainly
visible. Disconnect the vehicle battery
+12V and Ground connections before
installation.

Dash Bracket Installation: The dash control mounts with two screws,

which attach to the underside of the dashboard. Slide under the
dash and place the dash control in its mounting position, mark
the two best mounting holes, carefully drill pilot holes without
damaging any under-dash wiring, and secure with two screws.

Custom Installation: For that custom, nished look, the dash control

can be ush mounted directly on the dash-board (or anywhere

12

else). Disassemble the dash control from the mounting bracket.
Drill a 9/32” (7 mm) hole in the dashboard for the control along
with a 3/32” (2.3 mm) hole for the lock tab and a 1/8” (3 mm)
hole(s) for the LED holder. Reassemble the dash control compo­nents on the dashboard.

1. When the left (blue) LED is on, turn the remote knob clockwise to
turn the level up, and counterclockwise to turn it down. As it is an
endless knob, turning it more than one turn clockwise would be
maximum, and more than one turn counter-clockwise is mini­mum.

2. To recall a memory preset with the ACR-3, press the knob in to
switch from blue mode (volume control) to red mode (preset
recall). If, within two seconds, you turn the knob clockwise one
click, it will recall one preset higher than you are currently operat­ing. If, within two seconds, you turn the knob counter-clockwise,
it will recall one preset lower than you are currently operating (for
example, to change from Memory 2 to Memory 1).

There is no ‘wrapping’ to the knob, that is, turning the knob clock-

wise from Memory 4 will only recall Memory 4 and not conjure
up a 5 or a 1. Once a preset memory has been selected, or two
seconds have passed, the red LED will blink to show you the num­ber of the preset you are recalling, then return to the blue (volume
control) mode. The operation of the ACR-3 as a level control can
be turned on or o in the Output View section of the computer
display, see page 31.

1. Speaker-Level Inputs – The speaker-level output from am­pliers and factory installed radios can connect here, so the
DM-608/DM-810 will receive the audio signals this way and
do its thing. Make sure that you follow the plus and minus
polarity markings on the DM-608/DM-810 and match it to
the polarity of the speaker wiring. Analog signal entering the
DM-608/DM-810 are the sum of the speaker-level inputs and the
respective RCA Line-level inputs.

1110 12 13 14

2. RCA Analog Line-Level Inputs – The line-level output from the
head unit or factory-installed radios can connect here, so the
DM-608/DM-810 will receive the line-level audio signals. The
inputs are 1-2 (stereo), 3-4 (stereo), 5 (mono), 6 (mono), and 7-8
(stereo). Note that inputs 7 and 8 will default to the digital inputs
(3) if there is a digital input signal present. Inputs 1-2 have the
GTO™ (great turn on) signal-sense circuit that will awaken the
DM-608/DM-810 when an analog input signal is present.

3. Coaxial and Optical Digital Inputs – These S/PDIF and Toslink

inputs allow you to connect the digital audio output from source
units. These inputs share the use of inputs 7 and 8 as follows: If a
digital signal is present, then input channels 7 and 8 receive the
audio from the digital source. If there is no digital signal present,
then inputs 7 and 8 are the sum of the speaker-level inputs 7 and
8, analog line-inputs 7 and 8, and any streaming audio coming in
via Bluetooth connection on the Option Port.

4. RCA Analog Line-Level Outputs – These line-level analog out­puts from the DM-608/DM-810 connect to the line-level inputs of
your power ampliers and other equipment. The matrix capa­bilities of the DM-608/DM-810 allow you to pick and choose the
outputs from any combination of inputs, add crossovers and EQ as
required.

5. Remote Control Connector – This connects to the optional
ACR-3 remote level control using a standard telephone cord and
connectors.

6. USB Micro Connector – This connects to the USB A port of your
computer in order to use the control software to congure the
DM-608/DM-810.

7. Options Port – This port allows you to connect our optional Blue­tooth adapter, so you can stream audio into channels 7 and 8 from
your Bluetooth-enabled devices. Further details will be available
when this accessory and others become available.

Bluetooth
Option

8. Power Input Terminal +12V – This screw terminal connects to
the +12V battery binding post of the vehicle. Use quality insulated
wire.

Power Input Terminal Ground – This screw terminal connects to

a good ground connection on the vehicle. Use quality insulated
wire.

Remote Power Input Terminal – This screw terminal connects to

the 12V remote trigger output of some head units. When the head
unit is turned on, then the DM-608/DM-810 will turn on. Alterna­tively, you can use the GTO feature of the DM-608/DM-810 so it
will turn on when an audio signal is detected at the speaker-level
or line-level inputs of channels 1-2.

Remote Power Output Terminal – This screw terminal con-

nects to the 12V remote trigger input of other units and ampli­ers down the line. When the head unit is turned on, then the
DM-608/DM-810 will turn on and this daisy-chain connection will
allow other units in your system to turn on.

9. Maximized Input LEDs – These LEDs illuminate when a maxi­mum audio signal is present on any of the analog audio inputs.
During power-up, these LEDs and the output LEDs will turn on
momentarily, one after the other. Turn down the levels if these
LEDs are on a lot.

10. MILC™ Source Clip LED – The MILC™ (Maximum Input Level
Control) patent-pending level-setting circuit (on inputs 1-2 only)
prevents clipping and damaging distortion. It calculates when the
waveform of an incoming audio signal is clipping, and if it is, this
LED will fulll its destiny and shine forth.

With this advanced feature, you are able to optimize the level of

the incoming audio signal until the Source Clip LED is just-prior
to lighting. If the LED comes on during normal operation, you
should adjust the level of the audio signals before they reach the
DM-608/DM-810.

After an interview with the lead engineer included the words

“dierential calculus,” and some hieroglyphics on a chalk board,
the technical writer’s eyes glazed over and he had to be brought
round with a nice cup of tea and two donuts with sprinkles.

1110 12 13 14

11. Maximized Output LEDs – These LEDs illuminate when there is
maximum signal present on any of the analog audio outputs. Turn
down the output levels if these LEDs are on a lot.

12. USB Activity LED – This LED turns on when there is USB activity
between the DM-608/DM-810 and a computer.

13. Power LED – If you have connected your battery power, vehicle
ground, and turn-on lead (or GTO signal sensing) correctly, then
this LED should turn red to indicate the power is ON.

14. Mounting Holes – These 4 holes are used for mounting the
DM-608/DM-810 securely to your vehicle.

year_make_model_option.auc, for example: 2009_chev_silv_non­bose.auc, or simply give yourself a template to use when installing
subsequent DM-608/DM-810 units in the future.

1. The top line shows the currently-loaded .auc le. An * next to the
lename indicates that there have been changes made from the
stored settings.

2. New – Select this to create a new default le which will write over
the currently-loaded le.

3. Open – Allows you to browse and open up a previously-saved
le. A progress bar will appear, and this may take some time as all
parameters are transferred. Just hang in there, all will be well.

4. Save – Save the current settings as a le with the same lename as
currently loaded.

5. Save as – Save the current settings as a le with a dierent le­name as currently loaded.

6. Export log le – Exports a text le containing a stream of text sta­tus messages from the current log-in session. This may be used for
diagnostics of a system problem, and then interpreted by our ne
technical support folks during their afternoon dream-time, yoga,
and tea-leaf reading sessions (yes, we know, sigh).

7. Exit – Leave the application. The DM-608/DM-810 will continue to
operate, using the settings made during the online session.

Tools Menu

The Tools Menu oers a few handy features, as one can never have
too many tools. Keep them sharp, clean, and bright, and store away
from children. Sand and varnish any wooden handles.

1. Set EQ at – This is a quick way of returning the EQ curves to the
at state.

2. Output Delay type – This allows you to select the output delay
units from length units in inches and metric, or time units in ms. In
terms of sound waves, 1 ms is approximately the time it takes for
sound to travel 1 foot, unless you are playing faster than usual.

3. Reset hardware to factory settings – Allows you to..well..reset the
hardware to the factory settings. You might try this if you are not
sure of the current settings, and want to start again with a clean
new start, fresh as a morning in early spring.

4. Set PIN – This allows you to change the secret security PIN number
from its initial factory setting of 1234, to a value all of your own.
Record the number on a piece of paper, memorize and eat it.

Chapter 8: The Display

Memory Menu

Four memory locations are available at the top right of the display for
easy storage and recall of your settings. The optional ACR-3 remote
can also be used to easily recall these memory settings.

1. Adjust the DM-608/DM-810 settings until you are quite happy
with things. Then press and hold one of these numbers to store
your settings in a memory location. This will allow you to store
four separate tunings for an installation and compare them, or
recall them for separate input sources or EQ curves.

2. Press any memory number to recall it to mind.

3. Note that the crossover settings are NOT stored in the memory
settings. This is intentional, so that the tweeter crossovers are not
accidentally changed during use, as the memory locations will be
recallable during operation using an ACR-3 remote control.

4. To recall a memory preset with the optional ACR-3 during normal
(non-computer) operation, press the knob in to switch from blue
mode (volume control) to red mode (preset recall). If, within two
seconds, you turn the knob clockwise one click, it will recall one
preset higher than you are currently operating. If, within two sec­onds, you turn the knob counter-clockwise, it will recall one preset
lower than you are currently operating (for example, to change
from Memory 2 to Memory 1).

There is no ‘wrapping’ to the knob, that is turning the knob clock-

wise from Memory 4 will only recall Memory 4 and not conjure
up a 5 or a 1. Once a preset memory has been selected, or two
seconds have passed, the red LED will blink to show you the num­ber of the preset you are recalling, then return to the blue (volume
control) mode.

Chapter 8: The Display: Input View

Input View

This display allows you to set the input gains,
polarities and delays. The goal of the Input
View display is to get all of the signals arriv­ing to the DM-608/DM-810 evenly balanced
in level, and time-aligned so that they can be
summed as desired later. The integrated Real
Time Analyzer (RTA) is helpful in achieving
this objective.

1. Select an input or input pair from this
row, then the parameters shown will be
for this input or input pair.

26

Installation Manual

Chapter 8: The Display: Input View

Input Gain

1. The input gain control is a slider that can be adjusted with the
mouse, arrow keys, or by numerically entering the level in dB. The
slider will move in 1 dB increments with left and right arrow key
strokes. This includes any typed-in a value, such as “-2.3” dB, then
an arrow key left will be “-3.3” dB.

2. The input signals can be quickly muted with the MUTE button.

3. Inputs 1-2 have the MILC™ circuit (see page 15) and show a yellow
CLIP light at the right side of this area. This comes on if the input
signals 1-2 are at too high a level, and the MILC™ circuit has
fullled its destiny. Turn down the input levels 1-2 to prevent this
CLIP light from coming on.

4. The input RTA is quite useful to visually conrm when each input
pair is matched in level with the others. When the source is at
maximum with pink noise, the input RTA should t the signal
nicely on the 80 dB scale.

Delay

1. The delay of each input channel can be adjusted with these sliders
and the numeric display.

2. The 180 degree phase button is a very useful feature for a quick
polarity check, and to impress your friends.

3. TIP: use the head unit’s balance control to move the signal left and
right: If the RTA gets bigger when the balance is in the middle,
then the left and right have the same polarity. If the RTA gets
smaller when the balance control is centered, then the left and
right inputs have opposite polarity. So, rather than go back to the
trunk and try to sort out the wiring harness, simply use the 180
deg buttons to determine which is the interloper. The Input RTA
will also show you which channels arriving are limited bandwidth
(high pass / low pass), this will help you determine which inputs
to use for Output Summing for a full range output.

27

Chapter 8: The Display: Input View

Here are a few key items to note about the Input section:

1. Speaker level inputs are summed with line level inputs for the
same number.

2. Speaker level inputs are less sensitive than line level Inputs, as one
would expect.

3. Inputs 5 and 6 are discreet MONO inputs, primarily for use as
center and subwoofer inputs.

4. Inputs 7-8 are set with the following priorities:

1st Coaxial digital (S/PDIF)

2nd Optical digital (TOSLINK)

3rd Analog (RCA line-level inputs/speaker-level inputs /

Option Port)

This means that if the DM-608/DM-810 detects a valid digital

input to either the coax or optical input, the analog input will be
muted. If no valid bitstream is detected then the digital inputs
will be muted and the analog inputs will be enabled.

5. The input gain sliders allow a range of gain adjustment in the
analog domain, before the ADC. This allows the DM-608/DM-810
the unmatched capability to maximize headroom as well as noise
oor performance. The dynamic range of a pot with the conve­nience of an app.

28

Installation Manual

Chapter 8: The Display: Input View

RTA (Input)

1. The input RTA shows the level of signal at the input of the DSP,
post gain control (that is, after the gain control has done its thing).

2. For stereo inputs, the RTA shown is the sum of the left and right
channels, so if you have two channels out of phase, very little will
show. If your left and right channels are not time-aligned, you will
see comb ltering.

3. The sensitivity control is labeled to match the classic AudioControl
SA-3050.

4. The speed control changes the settling rate (fast, medium, slow).
Note that the low frequencies always have a slower settling time
than the higher frequencies, as they require longer to stabilize.

29

Chapter 8: The Display: Output View

Output View

This is where you will spend the majority
of your tuning time, as it is where you will
set routing and summing, output levels,
crossovers, EQ and AccuBASS® settings. The
DM-608 has 3 stereo outputs and 2 discreet
mono outputs. The DM-810 has 4 stereo out­puts and 2 discreet mono outputs. Any of the
stereo outputs can be summed to mono. The
DM-608/DM-810 is exceptionally exible, and
can be congured to use any output in any
bandwidth or source and match the needs of
the installation.

1. Select an output from this list, and it will
be highlighted in glorious living grey.
Then all the parameters shown are for this
output or output pair.

Installation Manual

Chapter 8: The Display: Output View

Output Summing and Level

This section allows you to sum multiple inputs into the output chan­nel(s) currently selected. Any blue inputs are present at the output.

1. Example 1: to sum the factory front low and front high with the
factory center into a single stereo pair:

a. Connect the factory front low to inputs 1-2
b. Connect the factory front high to inputs 3-4
c. Connect the factory center to input 5
d. Go to output view, output channels 1-2, and set the out-

put summing for 1-2, 3-4 and 5 to on (blue)

2. Example 2: to use a streaming device for music on all outputs
channels, but retain the factory door chime / phone on the front
channels.

a. Connect the factory front to inputs 1-2
b. Connect the streaming device to inputs 7-8 (or Option

port)

c. Go to output view, output summing, and enable

inputs 7-8 on all outputs

d. Enable inputs 1-2 on outputs 1-2 (or whichever outputs

you are using for the front speakers)

3. Adjust the output levels to match the sensitivity of the ampliers,
using the mouse or arrow buttons to increase or decrease.

Crossover

Every output has both high-pass and low-pass lters, with the ability
to set the band to the limits of human hearing. To make multi-way
systems easier to set, you can LINK outputs (in the Output Congura­tion section) to have the high pass lter of one output pair adjust the
low pass lter on another output pair.

ACR-3 Remote

This control allows you to adjust any set of the output levels with the
optional ACR-3 remote. One common use is to set output 10 as a sub­woofer output and enable the ACR-3 to control this particular output.
Another popular use is to set the ACR-3 as a master volume control by
enabling the ACR-3 remote for all outputs.

31

Chapter 8: The Display: Output View

32

Output Conguration

1. Mono: This allows you to sum any stereo pair down to mono. This
feature, in combination with the Input View polarity controls, are
very useful for checking input polarity and time alignment by
applying the knowledge that two signals time-aligned and of in­verse polarity, will cancel each other out when summed to mono.

2. 180 Deg: Invert the polarity of the output selected. Blue is 180
deg, black is 0 deg. Changing this control is much easier than
getting back in the trunk and rewiring the amplier outputs.

3. Link: This control is intended to speed up the tuning of multi-way
systems by linking two outputs so that their SUMMING, EQ, Delay
and Level are adjusted in tandem. The crossover Low-Pass setting
of the lower numbered output pair is linked with the High-Pass
setting of the higher numbered pair. A popular setting for this
is outputs 1-2 = Front Woofers and outputs 3-4 = Front Tweeters.
After adjusting in Link, you can unlink the outputs if, for example,
you want to set the tweeter delays independent of the woofer
delays, or if you wish to ne tune the crossover settings between
the woofers and tweeters.

Delay / Distance

1. These delay controls are for independent delay of any output
signal. This allows for sweet spot adjustments left/right, as well as
front/back sound stage presentation and woofer/tweeter arrival
time alignment.

a. In DISTANCE mode (inches or metric), set the distances

exactly as you measure them from the speakers to the
sweet spot (usually the driver’s headrest or center of the
listening area). The DM Smart DSP application will use
these distances to calculate the correct delay osets for
simultaneous arrival of all signals.

b. In DELAY mode (milliseconds) you can directly enter the

delay times in milliseconds.

NOTE: the DELAY / DISTANCE settings are stored by preset, so

you can easily compare multiple versions of the same set­up with minor tweaks, or set dierent proles for dierent
passenger congurations.

AccuBASS®

This is AudioControl’s patented bass restoration for factory head units.

1. Threshold: This slider selects the level at which the AccuBASS®
processing is activated. Use the ACTIVE indicator to help set
this control. Signals below the threshold are not aected by the
AccuBASS® processing.

a. Slider fully LEFT is maximum sensitivity (lowest threshold)

b. Slider fully RIGHT is minimum sensitivity (highest threshold)

2. Level: This slider selects the amount of boost that is applied when
the AccuBASS® is active.

3. Bypass: This button disables the AccuBASS® entirely for the select­ed output.

4. ACTIVE: This indicator is dark green when the signal has been
below the threshold for ten seconds. The indicator is bright green
when the signal has exceeded the threshold within the last ten
seconds.

Chapter 8: The Display: Output View

EQ

34

The DM-608/DM-810 features a graphic EQ with a few twists:

1. Modes

a. 30 band mode: 30 bands of 1/3rd octave EQ
b. 10 band mode: 10 bands of 1 octave EQ
c. 14 band mode: a mix of 1/3rd octave EQ in the bass re-

gion and 1 octave EQ in the midrange and treble regions.

2. The active band has a larger bubble and highlighted color.

a. Use the left/right arrow keys to navigate between bands
b. Use the up/down arrow keys to adjust levels (0.1 dB/click)

3. Any settings made in 30-band mode will be approximated when
toggled to 10 or 14-band mode. If you then revert to 30-band
mode, your settings will be retained.

4. The Draw EQ button allows you to use a mouse to quickly approxi­mate an EQ curve.

5. The Bypass button disables the EQ entirely for the selected out­put. This is useful for a quick comparison.

6. Setting the EQ – Play pink noise through the source unit and look
at the Output View RTA for each output channel (pair). If you see
a reasonably at response with the RTA set to S (slow), then you
don’t necessarily need to add EQ. If you are integrating with a
factory head unit, you will likely NOT see a at RTA response, so
use the EQ bubbles to atten out the factory EQ. Use the keyboard
arrow keys to set EQ, as it is very easy to select the slider left and
right, then use the up and down keys to set the value in 0.1 dB (!)
increments. Alternately you can quickly set the EQ using a mouse
with the Draw EQ option.

Chapter 8: The Display: Output View

AutoEQ

The AutoEQ is a tool for quickly and accurately undoing the EQ from
a factory head unit and achieving a at frequency response to the
DM-608/DM-810 outputs.

1. To use AutoEQ, connect a pink noise source to the factory head
unit (you can download a pink noise le from www.audiocontrol.
com).

2. Conrm signal presence with the Output RTA, and engage the
AUTO button.

3. After analyzing the incoming frequency spectrum, the software
will propose a new EQ curve. You can either accept the proposed
EQ curve or reject it. If you reject it, the proposed EQ curve the EQ
will go back to the setting before the AUTO button was engaged.

AutoEQ Hints

a. The AutoEQ analyzes the signal before the output MUTE, so if you

don’t want to listen to pink noise you can run the AutoEQ with all
of the outputs muted.

b. The AutoEQ only focuses on one output section at a time, so that

adjustments to the Front EQ do not interfere with adjustments to
the Rear or Center EQs.

c. The AutoEQ further renes adjustments with multiple passes, so if

the factory head unit requires major EQ changes you can run the
AutoEQ again one or two times to allow the DSP to make major
changes on the rst pass, then successively more delicate changes
to the EQ curve to approach a ruler-at response.

d. Again, you can reject any changes that the AutoEQ proposes on

any pass. This is so that if something unexpected happens during
the AutoEQ process, such as reaching the end of the Pink Noise
track, you can take a step back and repeat. You are the pilot in
charge, not a passenger on this journey.

e. At least a few of the RTA bands need to be over the 0 line for

proper, valid, and meaningful calculations.

f. Dad says..If your car heater stops working in cold weather, and

you would rather be toasty and warm, you might try checking the
water level in your radiator (when it is cooled), in case it has run
too low. (A cold heater is one of the rst signs of low water level.)
Then you can enjoy your AutoEQ more.

Chapter 8: The Display: Output View

RTA (Output)

36

1. For stereo outputs, the RTA shown is the sum of the left and right
channels, so if you have two channels out of phase, very little will
show. If your left and right channels are not time-aligned, you will
see comb ltering.

2. The sensitivity control is labeled to match the classic AudioControl
SA-3050.

3. The speed control changes the settling rate (fast, medium, slow).
Note that the low frequencies always have a slower settling time
than the higher frequencies as they require longer to stabilize.

4. The output RTA shows the level of signal at the output of the DSP,
after time alignment, summing, AccuBASS® and EQ, but before
the output level and MUTE control. The practical value of this is
that you can tune the EQ in a car with the outputs MUTED and not
have to listen to pink noise.

Troubleshooting

38

Many problems can be eliminated by re-checking the wiring and
settings of the unit. If a problem cannot be solved using the guide
below, please call the AudioControl team for further assistance, or
e-mail us at [e-mail]

1. No Sound

a. Verify the Power LED is a splendid red.

b. Verify the ampliers are on.

c. Verify the source unit is operating.

d. Check the speaker connections.

e. Check the power fuses on the amplier.

f. Check the ACR-3 (in blue-LED mode) is not at minimum.

g. Check the output RTA for activity, and the MUTE buttons. For

example, check that you have not accidentally saved all the
preset memories with MUTE on all of the outputs.

2. Source Clip LED is on:

a. Turn down the level of the audio signals entering the DM-608/

DM-810. The DM-608/DM-810 analyses the incoming audio on
channels 1-2, and detects if the signal is clipping. Make sure
the settings in other equipment in your system, such as EQ
controls, are not over-done and clipping the signals.

3. Speaker channels are cutting in and out:

a. Make sure the speaker impedance is not less than the recom-

mended minimum impedance.

b. There may be a short in the wires. Suspect a short if the prob-

lem happens only at the highest volumes.

c. Make sure subwoofers are not being overdriven, beyond their

recommended level.

4. Speaker Buzzing or Crackling at high volume:

a. Reduce any preamplier/equalizer low-frequency boost.

b. Check the DM-608/DM-810 Source Clip LED is not on.

c. Try playing something dierent and see if it occurs again.

d. Adjust the DM-608/DM-810 so the levels going in (Source Clip)

and going out (Gain Maximized) are optimized.

e. Note: Scratching your ear with your car keys may cause your

head to start up.

First, if you need service, it is probably best to go and see a trained
health care professional.

Please visit our AudioControl knowledge base at web address:
www.audiocontrol.com/knowledge-base. This may help you nd a
solution to your problem.

If you are fairly sure that the DM-608/DM-810 needs service, then
please contact AudioControl, either by e-mail or phone. We will verify
if there is anything wrong in the system that you can correct yourself,
or if it needs to be sent back to our factory for repair.

Please include the following items when returning the unit:

1. A copy of your proof of purchase. No originals please. We cannot
guarantee returning them to you.

2. A brief explanation of the trouble you are having with the unit.
(You’d be surprised how many people forget this.) If you can
supply a really detailed description of the problem, this would be
so much better, and our service technicians may add you to their
Christmas Card list. Please include any notes about the system
and other components you are using. Is it an intermittent prob­lem, or all the time?

3. A return street address. (No PO Boxes, please).

4. A daytime phone number in case our technicians have a ques­tion about the problem you are having, or if they are just feeling
lonely.

5. Package the unit in the original packaging if you still have it, and if
the kids are not using it for art supplies. Use great care and plenty
of good packing materials to protect the unit and prevent it from
moving about inside the box. Do not use loose materials like
packing peanuts or real peanuts.

You are responsible for the freight charges to us, but we’ll pay the
return freight back as long as the unit is under warranty. We match
whatever shipping method you use to send it to us, so if you return
the unit overnight freight, we send it back overnight. We recommend
United Parcel Service (UPS) for most shipments.

People are confused by warranties! Lots of ne print. Months of wait­ing around. Well, fear no more AudioControl is here. Our warranty is
designed to make you rave about AudioControl. It’s a warranty that
looks out for our customers, plus helps you resist the temptation to
have your friend, “who is good with electronics”, try to repair your
AudioControl product. So go ahead, read this warranty, then register
your AudioControl product at www.audiocontrol.com/product-regis­tration.

Our warranty has conditional conditions! “Conditional” doesn’t mean
anything ominous. The Federal Trade Commission tells all manu­facturers to use the term to indicate that certain conditions have to
be met before they’ll honor the warranty. If you meet all of these
conditions, AudioControl will, at its discretion, repair or replace any
AudioControl products that exhibit defects in materials and/or work­manship during the warranty on your product for ve (5) years from
the date you bought it, and we will x or replace it, at our option,
during that time.

Here are the conditional conditions:

1. You must fully register your purchase within 15 days of the pur­chase date by going to the AudioControl product registration
page at www.audiocontrol.com/product-registration. Failure to
register your product will negate the warranty.

2. You need to hold on to your sales receipt! All warranty service
requires original sales receipt documentation. The warranty only
applies to the original purchaser from an authorized AudioCon­trol dealer. Note: Products purchased from unauthorized dealers
are not covered under warranty.

3. If an authorized AudioControl dealer installs your AudioControl
product, the warranty is ve years, otherwise the warranty is
limited to one year.

4. Our warranty covers AudioControl products that have been
installed according to the instructions in the owner’s manual.

5. You cannot let anybody who isn’t: (A) the AudioControl factory; or
(B) somebody authorized in writing by AudioControl service your
AudioControl product. If anyone other than (A), or (B) messes
with your AudioControl product, the warranty is void.

6. The warranty is void if the serial number is altered, defaced or
removed, or if your product has been used improperly. Now that
may sound like a big loophole, but here is what we mean by this:
Unwarranted abuse is: (A) physical damage (don’t use your prod­uct to level your dining room table); (B) improper connections
(120 volts into the RCA jacks can fry the poor thing); (C) sadistic
things! This is the best product we know how to build, but for
example if you mount it to the front bumper of your car, drop it
over the Niagara Falls or use it for Clay Pigeon shooting practice,
something will go wrong.

Assuming you conform to 1 through 6, and it really isn’t all that hard
to do, we get the option of xing your product or replacing it with a
new one at our discretion.

In the event that your product is out of warranty or not covered under
our warranty you may request to have any damage repaired at our
normal “Out of Warranty” repair cost.

Legalese Section

This is the only warranty issued by AudioControl. This warranty gives
you specic legal rights, and you may also have rights that vary from
state to state. Promises of how well your AudioControl product will
work are not implied by this warranty. Other than what we’ve said
we’ll do in this warranty, we have no obligation, express or implied.
We make no warranty of merchantability or tness for any particular
purpose. Also neither we nor anyone else who has been involved in
the development or manufacture of the unit will have any liability of
any incidental, consequential, special or punitive damages, including
but not limited to any lost prots or damage to other parts of your
system by hooking up to the unit (whether the claim is one for breach
of warranty, negligence of other tort, or any other kind of claim).
Some states do not allow limitations of consequential damages.
