Frequency response: 20 Hz to 20 kHz, plus/minus 0.3 dB at 1 kHz Input impedance: 600 ohms (AC impedance) Output impedance: 600 ohms (AC impedance) Construction: alloy materials used in the audio signal isolator for durable, reliable assembly Function: isolates audio signals between connected devices while preserving signal integrity Compatibility and performance: impedance values suitable for systems expecting 600 ohms, supporting stable signal paths Use scenario: studio recording Connect a line level source to an interface or mixer while maintaining consistent impedance and preserving signal quality. Use scenario: live sound or broadcast rack Interconnect gear in a rack setup to help maintain stable operation and signal integrity across components. Use scenario: field recording or legacy equipment integration Link older gear to modern systems with reliable impedance and isolation to reduce interference and maintain sound quality
