The SMSL RAW-MHA1 is a compact digital power amplifier built around an Infineon high-power amplifier chip, rated 160W per channel, with XLR balanced and RCA line inputs, a Stereo/BTL bridge switch and a subwoofer line output. It suits desktop and bookshelf speaker setups fed by a DAC or preamp.
Who the SMSL RAW-MHA1 is for
Passive speaker setups: Rated 160W per channel, it powers a pair of passive speakers from a DAC or preamp.
Balanced sources: A front button switches between the XLR balanced and RCA line inputs, with an indicator for each.
2.1 systems: A subwoofer line output feeds a powered subwoofer alongside the main speakers.
Bridged mono: A rear Stereo/BTL switch turns it into a mono amplifier that SMSL says delivers twice the output power, with dedicated BTL terminals.
Skip it if: You need a DAC, Bluetooth or a remote: the RAW-MHA1 takes analog XLR and RCA signals only and is run from its front buttons and knob.
