Audio Amplifier Appraisal

QSC ISA 300T Professional Amplifier

The item is identified as a QSC ISA 300T Professional Amplifier. It is a rack-mountable audio power amplifier, visible in a black metallic casing with a generally rectangular form factor. The front panel features the prominent 'QSC' logo in white lettering. Below the logo, 'MODEL ISA 300T PROFESSIONAL AMPLIFIER' is clearly visible. The front face is characterized by two large, vertically oriented grilles for ventilation, suggesting a robust cooling system. Towards the bottom right of the front panel, there is a large rectangular rocker switch labeled 'ON' for power, accompanied by a small green LED indicator for 'Power' status. Further to the right, there are two sets of LED indicators arrayed vertically: a red 'CLIP' indicator, a yellow '-10' indicator, and a green 'SIGNAL' indicator for both 'CHANNEL 1' and 'CHANNEL 2'. The rear of the amplifier, partially visible in the upper background of the main image, shows various input and output connectors, including XLR-style inputs (labeled 'CH 2' is visible), and what appear to be binding posts for speaker outputs. A large fan grille is visible on the upper left rear, confirming active cooling. Various regulatory compliance labels (e.g., 'CE', 'UL') and technical specifications are present on the rear panel. The overall construction appears sturdy, made of sheet metal, indicating its intended use in professional audio environments. The condition appears good with no significant visible damage, although some dust accumulation is possible within the grilles.
