Take control of your vehicle’s sound with the Massive Audio DSP48 Digital Signal Processor. Featuring four high-level or low-level input channels, eight independently configurable RCA outputs and 8 Vrms RCA output voltage, the DSP48 provides flexible integration with factory and aftermarket audio systems.
Fine-tune each output channel with selectable 7-band or 15-band parametric equalization, adjustable crossovers, individual channel levels, 0°/180° polarity control and precise time alignment. Input summing allows signals from separate factory speaker channels to be combined, while custom routing lets you configure the outputs to match your amplifier and speaker setup.
Use the dedicated DSP48 app for iOS and Android to make adjustments in real time through Bluetooth® or USB. Stream music through Bluetooth®, play MP3 audio through USB, and save up to six tuning presets. Preset files can also be exported, imported and shared with other DSP48 users.
An Analog Devices processor, 48 kHz sampling and 24-bit conversion provide the foundation for detailed system tuning. The compact aluminum housing, hardware master-volume knob and visual signal indicators make the DSP48 convenient to install and operate.
