Overview

Rainbow SL-PA400 8-Channel DSP Amplifier – 8x55W

The Rainbow SL-PA400 combines an eight-channel digital signal processor with eight channels of amplification in a compact car audio component. It is designed for systems requiring more detailed signal control than a conventional four-channel amplifier can provide, including active two-way and three-way speaker configurations. Six high-level inputs support integration with compatible factory stereos, while two low-level inputs accommodate aftermarket source units and other line-level equipment. The eight amplified outputs each deliver up to 55W, providing a combined platform for powering multiple speakers without separate amplifiers. External Bluetooth connectivity provides an additional compatible signal option. With a frequency response of 20Hz–20kHz, signal-to-noise ratio of at least 90dB and total harmonic distortion of no more than 0.01%, the SL-PA400 is intended for professionally installed and tuned car audio systems where compactness, channel count and signal control are priorities.

Key Features

• Eight-Channel Amplification: Provides eight powered output channels for multi-speaker systems, active component sets and other complex installations.
• Integrated Digital Signal Processor: Combines audio processing and amplification in one chassis, reducing the number of separate components required.
• 8 × 55W Output: Supplies up to 55 watts across each of the eight amplified channels for compatible speakers.
• Six High-Level Inputs: Accept compatible speaker-level signals from factory stereos, assisting integration where RCA preamplifier outputs are unavailable.
• Two Low-Level Inputs: Support connection to compatible aftermarket head units, processors and other line-level audio sources.
• External Bluetooth Compatibility: Provides an additional wireless signal option when used with the appropriate Bluetooth connection.
• Eight Processed Channels: Supports individual signal distribution across multiple speakers for more precise system configuration and tuning.
• 20Hz–20kHz Frequency Response: Covers the conventional audible frequency range for full-range car audio reproduction.
• Low Harmonic Distortion: A total harmonic distortion rating of 0.01% or less helps preserve signal accuracy at appropriate operating levels.
• Compact Installation Size: The 240 × 185 × 52mm chassis consolidates processing and amplification while requiring less space than multiple separate components.

Ideal For

• Active two-way and three-way component speaker systems
• Factory stereo integration using high-level inputs
• Aftermarket head units with low-level outputs
• Multi-speaker front and rear audio installations
• Systems requiring eight independently processed channels
• Professionally installed and tuned car audio upgrades

The Rainbow SL-PA400 is considerably more than a conventional four-channel amplifier. Its integrated DSP and eight powered channels provide the foundation for sophisticated car audio systems while keeping the installation compact. Six high-level and two low-level inputs support factory and aftermarket source integration, while the eight 55W channels can drive compatible speakers throughout the vehicle. Professional installation and acoustic tuning are recommended to configure signal routing, output levels and speaker integration correctly for the intended vehicle and audio system.
