Morel MDSP64A 4-Channel Class AB DSP Amplifier with Built-In Bluetooth

Morel MDSP64A 4-Channel Class AB DSP Amplifier with Built-In Bluetooth

Compact, precise, and built for seamless OEM integration, the MDSP64A brings Morel's high-fidelity amplifier and DSP engineering into a single, installer-focused 4-channel unit with built-in Bluetooth streaming and full parametric control.

Product Overview

The MDSP64A is the entry-level model in Morel's MDSP amplifier series, delivering 25 watts RMS per channel at 4 ohms across four Class AB amplified outputs from a remarkably compact chassis measuring just 1.37" in height. Unlike the larger MDSP models, the MDSP64A features built-in Bluetooth as standard, providing wireless audio streaming and system control without an optional module. Four high-level speaker inputs allow direct connection to factory head unit speaker outputs, making OEM integration straightforward, while Morel's Speaker Load Assurance Module (SLAM) maintains factory amplifier stability throughout the integration process. High-resolution 24-bit/96kHz DSP processing with parametric EQ, fully adjustable crossovers, and per-channel input and output EQ provides complete, system-wide fine-tuning. Start/stop compatibility, automatic source switching, and DRC compatibility (optional controller) round out a feature set designed to simplify both installation and daily use. The MDSP64A outputs to four amplified speaker channels and two RCA low-level outputs for downstream signal distribution.

Features & Benefits

Built-In Bluetooth Streaming: Unlike other MDSP models where Bluetooth is an optional addition, the MDSP64A includes Bluetooth as a standard feature, enabling wireless audio streaming and user control directly from a paired mobile device without additional hardware.

High-Resolution 24-Bit/96kHz DSP Processing: The onboard DSP processes audio at 24-bit resolution and 96kHz sample rate, providing the headroom needed for transparent signal processing without introducing quantisation artefacts or processing noise into the signal chain.

Parametric EQ with Per-Channel Input and Output EQ: Fully adjustable parametric equalisation on both the input and output stages of each channel allows precise correction of OEM tonal characteristics and vehicle acoustic deficiencies at the source and output simultaneously.

Fully Adjustable Crossovers: Crossover frequency and slope are fully adjustable per channel, allowing the MDSP64A to be configured for any speaker system topology without external crossover components.

SLAM (Speaker Load Assurance Module): Morel's proprietary SLAM technology maintains factory amplifier stability when integrating with OEM systems using high-level speaker inputs, preventing load-related faults or instability in the factory head unit or amplifier during integration.

4-Channel High-Level Speaker Inputs: Four high-voltage speaker-level inputs allow direct connection to OEM or aftermarket speaker outputs without a separate line output converter, simplifying the wiring path in factory system upgrades.

Signal Summing: Onboard signal summing allows multiple input channels to be combined for flexible signal routing in OEM integration scenarios.

Start/Stop Compatibility: The MDSP64A is compatible with vehicles equipped with engine start/stop systems, preventing unwanted audio interruptions or amplifier faults during stop/start events.

Automatic Source Switching: Automatically selects the active audio source, eliminating the need for manual source management when multiple inputs are connected.

DRC Compatibility: Compatible with Morel's optional DRC (Digital Remote Controller) for physical system control from a convenient dash-mounted location.

TuneLink Multi-Amp Tuning: Supports TuneLink for multi-amplifier tuning from a single connected device, streamlining setup in systems using more than one MDSP amplifier.

Class AB Topology: The MDSP64A uses a Class AB amplifier output stage, delivering the linear, musical characteristics associated with Class AB design at the 25W x 4 power level suited to factory speaker replacement and modest aftermarket speaker systems.
