Our take on the JBL DSP4086 8-Channel Class D Car Amplifier with DSP

The JBL DSP4086 is a compact 8-channel Class D amplifier with a built-in digital signal processor. It delivers 40 watts RMS per channel at 4 ohms and 60 watts at 2 ohms, and its DSP is tuned from a Windows PC over USB. The real draw is the tuning depth: a 31-band EQ, adjustable crossovers from 20 Hz to 20 kHz with slopes up to 48 dB/octave, delay and phase control, and up to 10 saved presets. It suits listeners building an active system who want processing and power in one small chassis, but it is not a high-output amp and it needs a laptop to set up. Against separate amp-and-DSP combos it saves space and wiring; against bigger multichannel amps it gives up raw power.

About the JBL DSP4086 8-Channel Class D Car Amplifier with DSP

JBL DSP4086 8-Channel Car Amplifier With Digital Signal Processing — 40 Watts RMS x 8 One of the best ways to get superior sound fidelity in your car is to add an amplifier to pump up the power, along with a digital signal processor to fine-tune the sound quality. JBL's incredibly compact DSP4086 8-channel amp/processor will do both, providing eight channels of 40 watts RMS while sculpting the sound with powerful tuning software using your Windows PC. Connecting to the whole system. The DSP4086 was designed to take the signals from your vehicle's front speakers, rear speakers, front center channel, and rear subwoofer. You can then process those signals to create eight powered outputs, and you have the ability to power and control your front tweeters. Product Highlights: 8-channel car amplifier with digital signal processing 40 watts RMS x 8 at 4 ohms 60 watts RMS x 8 at 2 ohms DSP and EQ tuning tool adjustments made via USB connection to a Windows PC Save up to 10 presets Inputs: 6 assignable preamp and speaker-level (RCA adapters included) Outputs: 8 powered and processed Adjustment Details: 31-band EQ (selectable parametric or graphic) Adjustable high-, low-, and band-pass filters (20-20,000 Hz) Selectable filter slopes 6, 12, 18, 24, 30, 36, 42, 48 dB/octave) Adjustable delay: 0 to 12ms in 0.2ms increments Phase adjustment: 0 or 180° Programming done by a Windows-run PC Other Features: Includes wired remote for ch 7/8 Fuse rating: 40A x 1 Wiring and hardware not included with amplifier 8-gauge power and ground leads recommended Dimensions: 5-11/16"W x 2"H x 9-3/8"D Warranty: 1 year Our 30-day money-back guarantee MFR # DSP4086AM Amplifier: The DSP4086 features an ultra-efficient class-D amplifier that can provide 40W RMS @ 4Ω to each of the eight output channels, and 60W @ 2Ω. Internal conformal-coated PCBs are designed to withstand the harsh conditions of vehicle use and provide consistent power. Inputs: The DSP4086's built-in input harness features 6 RCA connectors for use with aftermarket radios with pre-amp outputs. If installing the processor with a factory radio, 6 RCA adapters with set-screw inputs let you connect to factory speaker-level signals. The software-based configuration lets you sum together separate tweeter, midrange, and woofer channels to a full-range signal that can be assigned to any of the 8 outputs. Input signals can range from 680mV all the way up to 15V. Outputs: The JBL processor/amplifier includes 8 powered speaker outputs on a removable 16-pin harness. Each output can provide 40W @4Ω and can be assigned to any of the input channels. Channels 7 & 8 can be assigned as subwoofer outputs, and can have their output level controlled via the included wired remote control.
