SMSL unveils with its DA-1 a small, affordable class D stereo amplifier featuring the essentials. It delivers 2x25W of power at 4Ω. In its compact format it embeds a TPA3118 class D amplification chip and a pop sound-control protection circuit to protect your speakers. Its circuit design ensures short signal paths for clean, pure sound output. In terms of connectivity, it features exclusively a stereo RCA input and a speaker terminal output.
Small but no less powerful, the TPA3118 amplifier chip chosen by SMSL for its DA-1 offers robust, reliable performance. Moreover, its short-circuit design allows the sound signal to pass through directly, avoiding any interference or impurities.
The DA-1's anti-pop circuit protects your speakers and your ears when the amplifier is switched on and during playback.
