This unique amplifier allows you to fine tune your system’s low frequency performance, and at the same time high pass to your mains (or satellites) protecting them from damage due to over excursion.

Features:

• DSP functions include: 5 PEQ bands, LPF, phase, subsonic filter, limiter, mains delay, and HPF
• Single-knob control panel with high-contrast LCD display and status LEDs
• Fast, intuitive PC-based GUI software enables full access to the DSP functions
• Efficient Class D output topology ensures high-impact low frequency performance
• Includes both balanced and unbalance line level inputs and outputs
• With a Dayton Audio 5 year warranty, it’s more than a guarantee, it’s a promise

Elite Control with DSP:

Dayton Audio’s SPA500DSP true 500 watt digital switching plate amplifier features advanced signal processing control that every audio enthusiast wants. With Class D output topology, the SPA500DSP delivers high-impact bass performance for thundering lows. Complete with multiple DSP functions including 5-band PEQ, LPF, phase, subsonic filter, limiter, delay, and HPF the SPA500DSP gives you the ultimate control to fine tune your audio system. This power and flexibility is accessible via PC-GUI software and our innovative single-knob LCD control panel.

Whether building a new subwoofer, or bringing an old speaker back to life by replacing an old plate amp, the Dayton Audio SPA500DSP is an excellent option.

DSP Plate Amplifier Features:

The SAP500DSP has all of the features to give you complete control over your entire audio system from the back of the amp. The amp’s single-knob control panel allows you to fine tune your DSP settings on a high-contrast LCD display. The back of the amp also allows you to attenuate your input, select power mode, and connect to your computer via USB. With a variety of inputs including XLR-1/4″ TRS combo jacks and RCA, the SPA500DSP allows you to connect to virtually any source. XLR and RCA outputs allow you to pass signal to other systems or speakers, such as your mains. The SPA500DSP also has selectable 120/220 VAC power.

The compact size and lightweight design of the SPA500DSP fit into almost any subwoofer enclosure.

• USB Link Indicator: When the communication via USB with amp is successful, the GUI’s LED indicator will light green. Otherwise, LED stays red
• Processing Selection: Navigate across the DSP menu to adjust various DSP parameters
• Sub In/Out Monitor: Monitor the input signal and sub output signal levels.
• Tools Drop Down Menu: Utilities for amp DSP management
• Volume: Adjust the level (gain) of the subwoofer output
• Phase: Continuously adjustable phase from 0° to 180°

 

PEQ Window: Graphical trace is NRT editable. Bands can be shaped by cursor or direct input and/or sliders

5 Band-digital PEQ Adjustments:

a. Band On/Off: Bypass or enable by clicking the colorized 1~5 buttons

b. Center Frequency (CF): Adjust Center Frequency of each EQ band, 10~200Hz, steps: 1Hz.

c. Gain: Adjust the EQ gain (apparent volume), -12 ~ +6dB, steps: 0.1dB

d. Q (EQ width): Adjust the “Q” value, 0.4~16 , step: 0.1

Dual-Band Limiter Adjustments:

a. Threshold: Adjust the limiter threshold, 0~-12dB, step: 0.1dB

b. Attack: Adjust limiter’s “attack time”. This controls the time taken to attenuate signals over the threshold to the specified threshold level. Range: 1/5/10/20/100ms

c. Release: Adjust limiter’s “release time”. When signal is below threshold level, this controls the time taken to restore back to original level. Range: 60/120/240/480/1000/2000ms

d. Frequency: The crossover frequency point between the 2 bands: Band 1 (Low Frequency) & Band 2 (High Frequency).

This block controls the DSP parameters for line level output only.

Delay: Adjust the time difference between High Frequency out and Subwoofer out.

HPF Adjustments:

Filter ON/OFF: Bypass or Enable the selected filter

Slope: Select roll-off gradient of the selected filter: -12dB/-24dB per octave

Frequency: Adjust cut-off frequency of the selected filter

Digital Signal Processing Feature:

This unique amplifier allows you to fine tune your system’s low frequency performance, and at the same time high pass to your mains (or satellites) protecting them from damage due to over excursion. Digital Signal Processing features including 5 PEQ bands, LPF, phase, subsonic filter, limiter, mains delay, and HPF are accessible via a single-knob control panel on the back of the amp or a fast, intuitive PC-based GUI software.

Note: Windows 10 and 11 User Microsoft .net Framework 3.5 is required for the SPA500-DSP software to run properly. This is not installed by default in Windows 10 or 11.
