The AWAVE DSP-12AD is a versatile 12-channel Class D amplifier featuring an integrated digital signal processor for precise audio control. It delivers a combined power output of 8 channels at 50 W and 4 channels at 100 W RMS into 4 Ohms, operating with an efficiency of 84%. The internal processing is handled by an ADAU1462 chip, supported by AKM AK5538 and AK4458VN converters that ensure a 192 kHz sampling rate and 32-bit core depth for high-fidelity sound reproduction. This unit offers extensive tuning options, including a 31-band parametric equalizer and flexible crossover settings with slopes ranging from 6 to 48 dB/oct across 68 frequency steps. You can fine-tune the audio further using phase control from 0 to 180° per channel and dedicated time correction. Connectivity is comprehensive, providing six low-level RCA and six high-level inputs, alongside optical TOSLINK and coaxial SPDIF digital options, while a USB-B port allows for easy PC connection. Housed in a black brushed aluminum case, the amplifier is designed for stability and durability within a 9 to 16 V DC power environment. It is well-suited for car audio enthusiasts who want to manage a complex speaker setup from a single device, with the possibility of adding a Bluetooth module with AptX HD or a digital remote for more convenient operation.
