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. Applications Small, powerful and costeffective, theSA502 is engineered for external amplification with SoundTube and other highfidelity 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.).
