SD-250 Mini Amplifier
The SD-250 is 50-watt per channel (8 ohm) Class D amplifier with maximum gain of 34 dB. Input options include balanced stereo euroblock, unbalanced line level mini jack, and a stereo speaker level (amplified) euroblock input for applications with low wattage speaker outputs. The SD-250 has three operating modes: stereo, dual mono, or bridged mono. In stereo, each input channel flows directly to its corresponding output channel. The SD-250 has three preset EQ settings for use with a SolidDrive speaker in drywall, glass and
wood. It also has a flat setting for unequalized full-range amplification. In dual mono, the left input is fed to both output channels. In bridged mono, the left input is fed to the bridged output (4-8 ohm only). System includes selectable 12-32 V external trigger input or auto standby to conserve energy.
Small, powerful and cost-effective, the SD-250 is engineered for external amplification with SolidDrive and other high-fidelity speakers. Additional applications include digital signage, education, point of purchase, museums, surgical centers, AV carts or any application where a small amplifier is needed to boost a limited source output (e.g., computers, A/V projectors, etc.).
