About the AudioControl DM-608

Signal processing makes it sound exactly the way you want

AudioControl designed their DM-608 digital signal processor to integrate into just about any car stereo system, to correct factory sound processing, and to deliver customized, high-fidelity audio to your aftermarket amps, speakers, and subs. You make adjustments and save settings  via your laptop (PC or Mac).

Signal processing makes it sound exactly the way you want

Smart-User DSP software

Smart-User DSP tuning software on a laptop (DM-810 version shown)

AudioControl designed their DM-608 digital signal processor to integrate into just about any car stereo system, to correct factory sound processing, and to deliver customized, high-fidelity audio to your aftermarket amps, speakers, and subs. You make adjustments and save settings  via your laptop (PC or Mac).

Serious audio adjustment

The Smart-User DSP software package includes Linkwitz-Riley crossovers, 30-band graphic equalizers, parametric filters, time delay/alignment for inputs and outputs, phase correction, AccuBass™ bass correction, and real-time analyzers (RTA) for the inputs and outputs so you can visually confirm the improvements in the sound.

The matrix is your friend

The DM-608 is "matrix-able," giving you the ability to combine and route any input to any output. So, if your car's factory system has separate pre-filtered, time-aligned, or amplified signals going to factory subs, mids, and tweeters, for instance, the DM-608 can combine them into one smooth, unified signal for you to balance, align, and tune for your better-sounding aftermarket speakers and subs.

Convenient features

Onboard LEDs indicate optimized signal flow for inputs and outputs, plus give you a warning when a source is too loud and causing distortion. An optional ACR-3 wired remote controller lets you select sources, control levels, and recall up to four preset tunings from your front seat. An optional Bluetooth® adapter lets you stream music and control the digital processing wirelessly from your compatible portable device.

Aftermarket hu vs factory with dsp

Matt from Temple, tx on 4/11/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

As a person who has spent countless hours reading reviews, figured I would actually write one. Let me preference this by saying before using and installing the 608 I went with aftermarket hu first. I was having a hard time trying to keep all my factory options on my 2017 sonata (swc, bc, aa, SiriusXM) pretty much all of it. So I decided to try out the dsp with factory hu so I can keep all my options. Price wise I would say if your like me and have all options on your car, then buying a nice am hu and the modules that go with it will end up being pretty close to the same. Now as for the dsp, sounds way better then the first setup I had. Keep all my speakers and amps the same( focal mids, Alpine sub) and the dsp sounds way better. The 4 star rating is because it takes a good while playing around with the software to get the sound where you want it. I spent about 5 hours today tuning the dsp and I still want to tinker with it some more. The Accu bass makes an amazing difference, the time delay and eq take some time to dial right. I didn't care much for the clipping light setup, to me doing it by ear is a much better sound setup. If I was a customer with all the goodies on my factory stereo, I would start with installing this first.

Pros: Clean sound, lots of adjustability, keep factory options

Cons: Not quick and easy to dial sound in, remote to keeps amps on, clipping sensors not great imo

Simple to install.

Easy to install. I used the digital optic input and have zero noise in my system. Manual online and in the box are vague. Not much information about using the digital inputs. A lot of adjustability though. I purchased scratch and dent which still looked flawless except for the wrong terminal blocks were supplies for the speaker level inputs. This would be ideal for multi amp setup. Over kill for my 5 channel although the crossovers are a great addition

Pros: Adjustability

Cons: Software

Great unit

Thomas from Indianapolis, IN on 8/3/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

The software was a bit confusing at first but I ended up catching on in about an hour. The unit needed updating before you run the software so your vehicle (laptop} needs to be close to wifi. Other than, it went smooth. I couldn't get the auto turn-on to work without a remote wire from my head unit but I'm going to look into that. It works as promised. It's an awesome crossover and equalizer. The bass enhancer is awesome especially used with the epicenter. Incredible bass. I love it and I recommend it.

Pros: Intuitive software Great sound

Cons: Price. But all of the good units are expensive.

Very good DSP

Matthew from Grand Rapids, MI on 9/20/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a great piece of hardware. Sounds great, low noise(non existant on digital inputs). I run all JL amps and speakers, and the sound is amazing compared to stock. 2014 Honda Pilot. Since I can't install an aftermarket HU in this vehicle, I use the speaker level input for the factory HU, then use a separate BT reciever with a digital optical cable for streaming and playing music from an android phone. Stock HU has a bit of hiss(noticeable even before install), so I wanted a clean digital input option. Sounds amazing! Using the optional remote, I can switch inputs from stock HU, then to my BT optical reciever. The remote then does normal subwoofer volume duty. If you want to compete, look elsewhere. For $100 more, you can get competitive products that offer more adjustability and features, but that also comes with complexity of adjustment. Simple to tune and dial in. Time alignment works great. Overall, highly recommend, although maybe overpriced at least $100.

Pros: Physical size, quality construction,excellent sound quality, simple to use tuning interface

Cons: Price vs features- NO independent adjustability of of output level or EQ on the L or R of a pair of channels How about that Bluetooth add on module, AudioConrtol?

Excellent unit

Verified employee purchase (What's this?)

This is a great piece of gear for anyone looking to integrate a factory head unit with outboard amps. I struggled with getting the sound the way I wanted it until I installed this unit and used the auto equalization. I was previously using a Kicker Front Row and find this does a much better job and is quieter as well.

Pros: Easy to install Auto equalization Great price/ features when compared to other DSP offerings

Cons: None so far

More details on the AudioControl DM-608

Product Research

Features

Overview: The DM-608 processor was designed to optimize car audio systems, whether factory or aftermarket, using AudioControl's DM Smart DSP app through a laptop. This is a fully featured Matrix DSP interface that gives you instant and clear control over every aspect of the processor and includes speaker and line-level inputs, digital audio inputs, 8 channels of output, signal summing, 30-bands of EQ, time-alignment, and much more. It also has AudioControl proprietary features like AccuBASS, GTO Signal Sense, MILC Clip Detection, as well as integrated input and output RTAs (Real Time Analyzer).

DM Smart DSP: The DM-608 includes a micro USB (Type-B) port to connect to a laptop (USB Type-A to micro-B cable included), allowing you to use AudioControl's DM Smart DSP app. This is a fully featured Matrix DSP interface designed to give you control over every aspect of the processor. Features include routing any input to any output, gain adjustment, delay, polarity, and a 30-band EQ. High-pass, low-pass, and band-pass filtering can be set up for any output using 12 or 24 dB/octave Linkwitz-Riley crossovers. It also includes RTAs (Real Time Analyzer) for every input and output to easily identify and sum factory speaker signals for OEM integration.

Maximum Input Level Control (MILC): The processor analyzes the input signal to detect any clipping. If the signal reaches the level of clipping, the MILC Source Clip LED glows red, prompting you to turn down the gain level. When the gain level is maximized, a green Maximized LED will glow to indicate the gain, for that set of channels, is set to the optimum level.

GTO (Great Turn On) Signal Sense: If you are connecting the DM-608 to a factory stereo, or an aftermarket unit without preamp outputs and a remote turn-on lead, the GTO Signal Sense circuitry can turn on the processor when an audio signal is detected on either the line-level or speaker-level inputs. After a period of time with no signal input, the DM-608 will turn itself off.

ACR-3 Remote: The optional AudioControl ACR-3 wired remote is a dual-function remote that lets you adjust both the level of the main and line outputs, as well as recalling memory presets, all from the driver's seat. The ACR-3 has two LED indicators and a rotary/push-knob. When the blue LED is on, the remote knob raises and lowers the output level. When the knob is pushed in, the red LED will light, allowing the knob to recall memory presets when turned.

Options Port: The DM-608 includes a proprietary 10-pin Molex socket allowing use of AudioControl's optional Bluetooth adaptor. This allows audio streaming into channels 7 and 8 from a Bluetooth-enabled device.

Top Panel: The top panel of the DM-608 has the labeling for all of the input/output connections, as well as the following LED indicators:

  • Power: If the amp is powering on correctly, this should be lit red.
  • USB Activity LED: This LED lights when there is USB activity between the amp and your computer during set up.
  • Maximized Input LEDs: These LEDs illuminate when a maximum audio signal is present on any of the analog audio inputs. Signal levels should be lowered if these LEDs are on a lot. Three LEDs are provided covering: Stereo 1/2, Mono 3/4, and Stereo 5/6.
  • Maximized Output LEDs: These LEDs illuminate when there is maximum signal present on any of the audio outputs. Signal levels should be lowered if these LEDs are on a lot. Four LEDs are provided, one each for: Stereo 1/2, Stereo 3/4, Stereo 5/6, and Mono 7/8.
  • MILC Source Clip LED: The MILC (Maximum Input Level Control) level-setting circuit prevents clipping and distortion. It calculates when the waveform of an incoming signal (on channels 1/2) is clipping and lights this LED. The level of the incoming signal should be set just prior to MILC LED coming on.

Connections: The DM-608's connections are aligned along the front of the processor for ease of installation. These include:

  • Power/Ground: A removable 4-pin Phoenix (Euroblock) connector is provided for Power, Ground, Remote In, and Remote Out. The Remote Out will send a turn-on signal to other devices whether the DM-608 is using the Remote In or GTO Signal Sensing.
  • Speaker Level Inputs: Three 4-pin Phoenix connectors are used for speaker level inputs: Stereo 1/2, Mono 3/4, and Stereo 5/6.
  • Line Level Inputs: Three pairs of RCA inputs are provided: Stereo 1/2, Mono 3/4, and Stereo 5/6.
  • Digital Inputs: This section includes both Coax and Optical digital inputs.
  • Line Level Outputs: Four pairs of RCA line outputs are provided to run to outboard amp(s). These are: Stereo 1/2, Stereo 3/4, Stereo 5/6, and Mono 7/8.
  • Options Port: Allows connection of AudioControl's optional Bluetooth adaptor.
  • ACR-3 Control: This RJ-14 telephone-type connection allows you to plug in the optional ACR-3 Remote. The ACR-3 is used to change the output level and for recalling memory presets.
  • USB: A micro-USB (Type-B) is used for connection to a computer for DSP configuration.

Q
Can volume still me controlled by head unit or do you have to use the ACR-3?
[ Steve  Mar 26, 2019 ]

A
Volume can be controlled by the head unit.
[ ROBERT W  Apr 04, 2019 ]
A
Head unit Volume is the main system volume control, but the ACR-3 does 2 things: You can use it as a bass volume knob and the most important you can use it to choose from different setups of equalization and TA you have set. For example I have a soundstage and a sorround set up I like to switch depending on the song
[ Dimas  Apr 02, 2019 ]
A
You can still use both volume controls. If your head unit changes EQ when turning up the volume then just use the ACR3 and set your Head unit to 3/4. My factory head unit does not change signal levels when I increase or decrease volume so I just use my head unit volume. I also use a Fiio X5iii with the digital input on the DM 608 on a second input. With this preset I must use the ACR3 to control the volume.
[ Brian F.  Apr 02, 2019 ]
A
Oh, you can still use your volume control on your head unit like always. You can boost the signal with the DM-608 but it's obviously not practical to use it as a volume control. All the remote does is change the program from 1-4.
[ Thomas  Apr 02, 2019 ]
A
The controller allows for control of subwoofer volume. It also allows u to toggle thru the presets. Volume of overall stereo is still controlled by the head unit. I believe u can still adjust the level of the sub via head unit but it's very convenient to use the controller.
[ Cedric  Apr 02, 2019 ]
A
The volume can still be controlled by the head unit, but you can program the DM-608 to use the ACR-3 to either subwoofer level, or use it as a volume knob.
[ Kevin  Apr 02, 2019 ]
A
Volume can be controlled by rhe soure completely. If using the bluetooth unit to stream directly to the dsp then volume is controlled by the bluetooth device. The acr3 can be setup to control the level on any of the output channels. It will also allow you to switch between dsp presets by pressing the button and clicking it.
[ Matthew  Apr 02, 2019 ]
A
This is only for gain and bass your volume is controlled by your head unit. Some store settings for bass can't remember if this does I haven't had this for a few years.
[ MIKE  Apr 02, 2019 ]
Q
Will I still use my Epicenter in path with the sub inputs ( so HU/ Epicenter/ DM-608/ Amp) to the DM-608? Or is it no longer needed?
[ Raymond  Nov 14, 2017 ]
2 answers
A
While the DM608 has tons of EQ functionality, it does not do the same thing as the Epicenter. So yes, you'd put the Epicenter in front of the DM608. Also, make sure the input to the Epicenter is a full range signal, not just a subwoofer signal. If the Epicenter is fed a signal that is only the low bass frequencies, it won't work as intended. There's lots more reading about this online at AutioControl's website.
[ Charlie  Nov 19, 2017 ]
A
The DM-608 has it all built in. Full eq for all your low ends. As long as you have a decent sub woofer amp, you won't need the Epicenter. The full range control of the DM is superb and does everything. My best investment in 20 years of having sound systems in any of my cars. Does take some time to fine tune though. But once you have your presets set, you don't have to mess with it again.

How does this work with component speakers that have crossovers?
[ Prmdc1  Sep 21, 2017 ]

The information Matthew was kind enough to share above is spot-on! There are several crossover options available when using component speakers with the AudioControl DM-608. If you'd like more details on what's best for your specific system, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
[ Larry  Sep 22, 2017 ]  Staff

You have several options. You can run the speaker's supplied passive xovers as is, just drive them full range on one pair of channel outputs. Or, you can drive them full active xover, and use the 608's xovers(you wont use the component's supplied crossover), using 4 channels. The benefits or drawbacks to choosing which way is best can be complicated to explain, but passive xovers, you cant typically adjust slope (some can) or xover frequency between woofer and tweeter. Another(big imo) drawback to passive is no output level adjustment between woofer and tweeter..important for a good sound stage. If you dont use the supplied passive xovers, be very careful with the tweeters, as low frequency can destroy them quickly. A simple filter capacitor is a good idea for protection against pops or clicks ect. If you have 4 channels of amplifier to spare, then go full active and dont use the component's xovers. Just be careful of the tweeters! You'll have the most adjustability this way, imo. Hope this helps.
