Features

  • Multi-Channel Flexibility: Configurable as a 4-channel, 3-channel, or 2-channel amplifier for use with a variety of car sound systems.
  • Perfect for OEM Integration and Aftermarket Builds: Features 6 speaker level inputs, 4 balanced RCA analog line-level preamp inputs, and 2 assignable preamp outputs. Input/output RTAs for each pair help you easily identify and sum factory speaker signals for precise and informed tuning.
  • Powerful Matrix DSP Capabilities: Pick and choose outputs from any combination of inputs, and add crossovers, filters, and EQ as needed. The DM Smart App gives you instant and clear control over every aspect of your processor, with a smart GUI and intuitive workflow.
  • Award-Winning Class D Amplifier Technology: Provides unprecedented output up to 800W (4 x 125W @ 4, 4 x 200W @ 2, 2 x 400 W @ 4 Bridged).
  • AccuBASS Restoration: Corrects bass roll-off caused by processing built-in to your factory head unit.
  • Built-In Diagnostic Codes: Provide exact insight should the amplifier detect a problem.
  • GTO Signal Sensing: Gracefully turns on your amplifier when an incoming audio signal is detected on inputs 1 and 2, then turns off after a period of time when the audio signal fades away to silence.
  • MILC Clip Detection with LED Indicator: Prevents clipping and potentially damaging distortion.
  • Selectable Crossovers: High-pass, low-pass, and band-pass crossovers (at 12and 24 dB/octave for Linkwitz-Riley or 18 dB/octave Butterworth) ensure only the correct frequencies reach your car audio speakers.
  • Graphic and Parametric Equalizers: A 30-band graphic EQ and 10-band parametric EQ per output channel provides precise, targeted tuning.

Description

Amplifier and DSP in one package Two keys to unlocking great sound in a car stereo system are serious power and extensive control - and this amp's got them both. For power, AudioControl's D-4.800 4-channel amplifier generates 125 watts RMS per channel, so it'll drive even the most demanding aftermarket speakers with plenty of headroom to spare. You could also bridge the D-4.800 to drive a couple subwoofers with 400 watts RMS each. Computer-controlled digital signal processing Smart-User DSP tuning software on a laptop (DM-810 version shown) You won't find any knobs on the D-4.800 - you make adjustments and save settings via your laptop (PC or Mac). AudioControl's Smart-User DSP software package includes 12 or 24 dB/octave Linkwitz-Riley crossovers, 30-band equalizers, parametric filters, time delay/alignment for inputs and outputs, phase correction, AccuBass(tm) bass correction, and real-time analyzers (RTA) for the inputs and outputs so you can visually confirm the improvements in the sound. It's made to work with a factory radio Six active speaker-level inputs allow you to connect this amp to almost any factory system, even ones that have separate pre-filtered, time-aligned, and amplified signals going to separate factory speakers and tweeters. The D-4.800 sums them into one smooth, unified signal for you to balance, align, and tune for your better-sounding aftermarket speakers. AudioControl's Great Turn On (GTO(tm)) signal-sensing circuitry turns the amp on automatically whenever it senses an input, so you won't have to run a separate turn-on lead back to the receiver. 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 presets from your front seat.

  • Excellent
First dap software that’s user friendly. Changed my whole sound

  • Excellent Amp -- Not Approved Reseller
This amp is just as fantastic as the hype suggests. It is easy to install with the right wiring kit (I used a KnuKonceptz 4AWG wire kit for 120amps) and requires no other special hardware to power it - just the stock battery or alternator. You will have to do some trial and error though, as the DSP is not for the faint at heart. Also note that if you're buying new speakers to pair this with, you will want to break them in fully first before seriously going in on the DSP settings. Otherwise you won't know what your new system actually sounds like until the speakers break in with use. Please note also that Amazon apparently is NOT an approved reseller for AudioCobtrol amps, so if you get a dud, there is no RMAing this back to AudioControl for replacement following the expiration of the Amazon return window or Amazon warranty if you bought one. ... show more

  • One of if not the best amps
This thing is awesome and probably one of the best amps out there. With that said the DSP software SUCKS when it comes to saving files the first time and honestly shouldn’t be as cumbersome as that feature is. Besides that love it. Definitely recommend.

  • Almost perfect. But still great.
Awesome amp. Could use a refresh. USB-C and on board Bluetooth would make this perfect. Currently the Bluetooth adapters are no where to be found or be scalped for near $1k for it. App is easy enough. Build is solid. Not my first audiocontrol device and likely won't be my last.

  • Junk
Amp worked fine all summer after being installed but now it's winter and every time I remote start my truck, it goes into protection. After research, this brand is very sensitive to voltage and known for being in protection with remote start / auto stop engines. I'll never buy Audiocontrol products again. ... show more

  • Well worth it!
It's a game changer, but be prepared for a learning curve. It'll most likely take a little trial and error--as it did for me, but once you get it, it a massive upgrade giving excellent sound and balance to you system.

  • Great sound. Be ready to learn the program.
Sounds great but the programming is a learning curve. Must have the correct Dell drivers or it is a bi_ch.
