The Audiomatica PRE-01 is a high-performance microphone preamplifier designed to enhance the acoustic measurements of the Audiomatica CLIO analyzer. Its versatility makes it suitable for various environments, including laboratory settings and field applications. Powered by a single 9V battery, the PRE-01 offers extended runtime of over 12 hours, ensuring uninterrupted measurements.
The PRE-01 boasts a wide frequency response of 7Hz to 110kHz, capturing a comprehensive range of acoustic signals. Its selectable weighting filters, including A, B, and C, allow users to simulate the frequency response of the human ear, providing accurate measurements in line with human perception. The inclusion of a 20dB gain stage enables amplification of the microphone signal, ensuring optimal signal strength for analysis.
With a high input impedance of 5600 ohms, the PRE-01 minimizes loading effects, maintaining the integrity of the signal. Its low noise of 0.01% at 1kHz ensures pristine recordings, free from unwanted distortions. The PRE-01's enhanced signal-to-noise ratio, increased dynamic range, and enhanced measurement accuracy make it an invaluable tool for acoustic engineers, acousticians, and audio professionals seeking reliable and accurate measurements.
