Whirlwind HATT-AES Overview

The HATT-AES Tabletop Active Headphone Amplifier from Whirlwind converts a digital AES3 stream into a high-fidelity, low-distortion stereo headphone signal optimized for 32 Ohms headphones. Sample rates from 32 kHz to 192 KHz are recognized by the HATT-AES D/A converters. The amplifier features 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 powert supply. Both 1/4” TRS and 3.5mm TRS headphone jacks are provided and the volume control adjusts the listening level. It is housed in a durable ABS box for placement anywhere a high-quality headphone driver is required.

Front Panel

The single volume control adjusts the level delivered to both left and right earpieces. The PWR LED indicates operational status, the LOCK LED shows connection with a valid AES3 stream (32 kHz to 192 KHz sample rates), and the CHA and CHB LEDs display analog audio presence at the output of the D/A converters.
Note: Although 1/4" TRS and 3.5mm TRS headphone jacks are included for convenience, only one jack should be used at a time.

Rear Panel

A 3.5mm stereo TRS jack is provided for injection of unbalanced stereo signals. The AES3 input is a female XLR. Both AES3 digital and 3.5mm analog inputs can be used together if required. The AES thru XLR male jack provides a buffered, latency free, output of the input signal for daisy-chaining several units together with the same AES3 stream. The 2.1mm power input jack is for connection to the model #PS6 6 VDC power supply.
