Description

The Whirlwind HATT-AES is an active headphone amplifier that converts a digital AES3 stream into a high fidelity, low distortion stereo headphone signal optimized for modern 32 Ohm headphones. Sample rates from 32 kHz to 192 KHz are recognized by the HATT-AES D/A converters. Features include an analog 3.5mm TRS stereo input jack, analog signal present LEDs, and a buffered AES loop-thru output. The headphone output can also be used as an unbalanced stereo line driver.
The HATT-AES is powered by an included model #PS6 « wall wart » supply. Both 1/4″ TRS and 3.5mm TRS headphone jacks are provided and the volume control adjusts the listening level. The HATT-AES is housed in an attractive, durable ABS box for placement anywhere a high quality headphone driver is required.
