Overview

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier

Dayton Audio SPA1000 1000 Watt Subwoofer Plate Amplifier

A Kilowatt of clean, reliable power

The Dayton Audio SPA1000 is one of the most technologically advanced subwoofer amplifiers on the market today! The Dayton Audio SPA1000 subwoofer amplifier is based on a state-of-the-art Class-G circuit topology that combines the proven high power, high fidelity characteristics of a Class-AB amplifier with a patented tracking down converter power supply to achieve an operating efficiency up to 86%. You get the efficiency of a Class-D amplifier without compromising audio quality and reliability. The Class-AB output stage provides the clean and low-distortion sound that audiophiles demand, without any of the instability problems that plague other high-efficiency amplifier designs.

Key Specs:

  • Channels: 1
  • Power Output @ 4 ohms (RMS): 950 Watts
  • Power Output @ 8 ohms (RMS): 500 Watts
  • Frequency Response: 20Hz - 200Hz
  • Inputs: 2x RCA Inputs, 1x LFE Input
  • Outputs: 1x Powered Output

Phase Switch

Correct misalignment between your speakers and your subwoofer with a phase inversion switch

Variable Crossover

Maintain a smooth transition from your full-range speakers with a variable low-pass filter.

Built-In Equalizer

Manage room nodes and resonances with the simple 1 band semi-parametric EQ

LFE Direct Input

Bypass the protection filters and crossover functionality with the LFE Direct input, perfect for use with high-end cinema processors

Class-G Innovation

The American-designed and engineered SPA1000 plate amplifier uses a patented Class-G topology that continuously tracks the input signal to modulate or control the voltage available to the output stage.

This "tracking" capability delivers the exact amount of power based on demand instead of constantly keeping it in reserve, so the output stage only draws the amount of power that is required at any given time. Less energy is wasted as heat, and more power is available for the subwoofer driver.

With its enhanced thermal management, the SPA1000 is an upgrade over previous models—making it a nearly bulletproof amplifier choice for today's demanding HT audio and music playback applications.

A-Class Features

On the SPA1000, the input and output connections are through your choice of either line level RCA connectors, or a direct LFE input which bypasses the filtering of the amplifier. A stereo input signal is summed to mono and sent to the internal low pass crossover, which is selectable from 50 to 200 Hz; the input gain sensitivity is fully adjustable as well. also included is a phase reverse switch, which helps you to achieve the best acoustical match with the rest of your speakers. Dial in the perfect tone with the single band EQ.

A large surface area heat sink is combined with internal overload, thermal, and short circuit protection so that you can expect years of reliable operation.

1. Low-Level Inputs (Left/Right) - RCA Style jacks that will accept standard line level inputs from a pre-amp level source.

2. LFE Direct Input - RCA Style input jack to bypass the internal filtering for a pure signal to the subwoofer

3. Power Connector Input - Accepts IEC plug for connection to mains

4. Volume (Gain) - This control will match the amplifier's input sensitivity to the output of the pre-amp source.

5. Frequency (Low-pass crossover) - This sets the highest frequency the subwoofer will reproduce and has a range between 50-200Hz with a slope of 18dB/Oct.

6. Power Switch - On, Off and Auto mode. When the “Auto” position is selected, the amp is in “stand by” mode until an input signal of about 10 millivolts or greater is detected. The amp will go back to standby mode 10-15 minutes after the input signal stops

7. Power LED - When the power switch is moved to the “on” position, the LED will illuminate green, and the amp will be in “On” mode. If the protection circuit detects a short circuit or thermal overload the unit will shut down and the LED will turn red

8. Phase - This two-position (NOR = 0° phase and REV = 180° phase) switch helps to compensate for differences in the acoustical and electrical characteristics between the subwoofer and the main system speakers.

9. Frequency (EQ) - Adjust the center frequency of the single band equalizer

    10. Bandwidth (EQ) - Adjusts the quality (Q) of the equalizer band

    11. Level (EQ) - boost or cut value of the single band equalizer

    12.Amplified Signal Output - Solderless disconnect terminals for driver connection: Red = 0.25" / Black = 0.205".
