SoundTube - SA502 - 50-Watt per Channel Class D Amplifier

SoundTube - SA502 - 50-Watt per Channel Class D Amplifier

34 dB maximum gain with 2 x 50 watt output. Three operating modes: stereo, mono or bridged mono. Three user selectable inputs: balanced stereo (Euroblock), stereo unbalanced mini jack, or high level Euroblock. External 12-32 V trigger. Signal detecting auto standby to con- serve energy. Dual concentric gain controls for inde- pendent channel control. 20 Hz- 20 kHz frequency response. 120 Hz high pass switch. Small size- 1.2″ x 3.9″ x 4″. Rugged aluminum housing.

The SA502 is 50-watt per channel (4 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 SA502 has three operating modes: stereo, dual mono, or bridged mono. In stereo, each input channel flows directly to its corresponding output channel. In dual mono, the left input is fed to both output channels. In bridged mono, the left input is fed to the bridged output. System includes selectable 12-32 v external trigger input or auto standby to conserve energy.

Small, powerful and cost-effective, the SA502 is engineered for external amplification with SoundTube 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.).
