SMSL PA200 – Stereo Power Amplifier on GaN Transistors
05.01.2025 05:50 | ~1 minute read
SMSL has introduced the SMSL PA200 stereo power amplifier – offering both volume control and switching to bridge mode. Thus, with one signal source, the owner can save on preamplifiers, and in the case of creating a multi-component installation, easily switch the system to monoblock amplification mode.
The output stages of the SMSL PA200 use Infineon GaN FET transistors, providing power up to 160 W for each of the two channels when operating on a load with a nominal resistance of 4 Ohms or up to 400 W at 4 Ohms in bridge mode. Harmonic distortion remains at a level of only 0.003%. The amplifier circuit uses premium components, including a Texas Instruments PGA2311 digital volume control.
Volume control is available only when using the amplifier in two-channel mode via unbalanced RCA inputs. In bridge mode via a balanced XLR input, the amplifier operates exclusively as a power amplifier, without signal level control.
The SMSL PA200 Stereo Power Amplifier is now available for purchase with a suggested retail price of $419.
