RDL / AV-HK1X

The RDL/AV-HK1X is a mono transformer isolation module for use with a balanced low impedance source and either low or high impedance loads.

■Features:

- Ground isolation for balanced lines

- Elimination of line-level ground loops

- Balanced mono galvanic isolation

- Isolation in harsh environments

- Modules for portable or permanent isolation

■Applications:

The AV-HK1X is a mono transformer isolated module for use with balanced low impedance audio and low or high impedance loads. Gold-plated XLR jacks are provided for input and output connections. The shield (pin 1) connection of the INPUT jack is electrically isolated from the case and from the output ground (pin 1) at the audio band. The shield (pin 1) connection of the OUTPUT jack is connected to the case shield. A user audio source such as a mixer, preamplifier or other professional audio equipment connects to the AV-HK1X INPUT. The output of the module should be connected to the input of a grounded audio system amplifier or mixer.

Galvanic isolation between the input and output is provided by a studio-quality audio transformer. The AV-HK1X breaks the ""ground loop"" connections that create hum in your sound system. Shielding the input connectors keeps your system resistant to radio interference and provides a radio frequency ground return.
The AV-HK1X is a rugged product designed for portable use. Mounting brackets are included for permanent installation.
