The Hosa ATT-448 is a professional audio input attenuator designed for precise signal level control in studio and live sound applications. This passive device allows for reliable reduction of audio signal levels without the need for an external power supply. With its balanced XLR3F (female) to XLR3M (male) connections, the ATT-448 provides a fixed attenuation of -20 dB to prevent input clipping and distortion in mixers and audio interfaces. The compact and sturdy metal housing ensures durability and reliability, while the nickel-plated connectors guarantee long-term use in demanding environments. The ATT-448 is particularly useful for connecting high-level sources such as synthesizers or drum machines to microphone inputs that require lower signal levels. Its passive design ensures that no unwanted coloration or noise is introduced into the signal path, making it ideal for critical recording and transmission applications.
