Dayton Audio Releases DSP-408 Signal Processor

Dayton Audio has released a new DSP loudspeaker signal processor intended for both home and car audio, the DSP-408. This is a feature-rich 4 input/8 output digital signal processor, featuring built-in EQ, crossovers, time alignment, and input/output mixing. Exploring all the features the DSP-408 offers, the ability to manipulate and improve the sound quality of an audio system is the most alluring aspect of this affordable unit.


Dayton Audio has released a new DSP loudspeaker signal processor intended for both home and car audio, the DSP-408. The Dayton Audio DSP-408 is a highly flexible digital signal processor that provides four inputs and eight outputs with the tools to develop electronic high-pass, lowpass, and band-pass filters combined with parametric equalization and delay. This device can be powered from a 12 V wall wart for home use or 12 V directly from a car battery. 

It can be configured and controlled via a Windows PC, Android device, or an iOS device, with the DSP-408 mobile apps offering the same full control over the DSP features as a PC. Software features include:
• 10-band parametric equalizer per channel
• High and low shelf EQ per channel
• Variable crossovers: high/low/band-pass slopes 0 to 24 dB, Linkwitz Riley/Butterworth/Bessel
• Time delay: 0 to 277 cm or 8.1471 ms adjustable in 1 cm steps
• Input/output mixing to customize the signal path
• Phase adjustment (0° to 180°)
• Customizable name/ID for each of the six presets
• Load, save, recall, or delete preset files
• Software controllable level attenuation on the preamp and high-level inputs
• Minimum/maximum voltage protection
• Reverse voltage protection
• Mute circuit and delay
 
Hardware features include:
• Four-channel high-level inputs with signal sensing turn-on
• Four-channel low-level RCA inputs
• Bluetooth 4.0 input for wireless connectivity and aptX audio streaming are available when paired with the Dayton Audio DSP-BT4.0 (purchased separately)
• Eight-channel 3.5 V RCA low-level outputs
• Real-time signal processing control
• Eighty bands of parametric EQ adjustment (10 bands per channel)
• DSP-RC multi-function wired remote allows for preset select and volume control (purchased separately)
• DSP-408 mobile tuning app for Android phones/tablets, which features full control of the DSP features

Technical specifications include:
• Analog Devices ADAU1701 SigmaDSP 28-/56-bit Audio Processor
• Minimum/maximum voltage protection
• Reverse voltage protection
• Mute circuit and delay
• High level input impedance: 180 Ω
• RCA input impedance: ≥20 kΩ
• Frequency response: 20 Hz to 20 kHz
• Output impedance: <50 Ω
• Maximum input level: ≥3.2 V
• Signal-to-noise ratio: ≥115 dB
• Remote out current: >500 mV
• Operating voltage: 9 V to 17 V

  Dayton Audio also makes two accessory items for the DSP-408—the DSP-BT4.0, which includes a Bluetooth Data and Streaming USB Interface, and the DSP-RC Wired Remote Control. The DSP-RC enables the user to remotely control the volume control for the DSP-408, as well as select any of the six available presets for the unit.
