Whirlwind HATTXL overview

  • 1Description

The HATTXL Tabletop Mono Active Headphone Amplifier from Whirlwind provides headphone volume control for broadcast applications, recording studios, and language labs. It can drive any impedance headphones, including 8 Ohm in-ear monitors. This mono headphone amplifier uses a mono balanced input via XLR connectors and sends the same signal to both the left and right earpieces. It also features an unbalanced 3.5mm TRS stereo input jack with the left and right summed to mono.

The control box is powered by an included PS242.1 wall wart supply. Both 1/4" TRS and 3.5mm TRS headphone jacks are provided and a volume control adjusts the listening levels. The amplifier is enclosed in a durable ABS box.

Front Panel

The single volume control adjusts the level delivered to both left and right earpieces. The power LED indicates operational status. 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

Female and male XLR connectors are paralleled for looping the mono balanced line level input signal. As many as 25 units can be daisy-chained together with a single feed line. Pin 2 is positive, pin 3 is negative, and pin 1 is shield. A separate 3.5mm stereo TRS jack is provided for injection of unbalanced stereo signals. The left and right are summed and delivered to the headphone outputs in mono. Both XLR and 3.5mm inputs can be used together if required. The 2.1mm power input jack is for connection to the 24 VDC/200mA power supply.
