About RDL AV-HK1

Experience superior audio quality with the AV-HK1 HUM KILLER Stereo Audio Isolation Transformer, a high-performance module designed for unbalanced, high impedance audio inputs. This stereo transformer isolation module features gold-plated phono jacks for both input and output connections, ensuring optimal signal transmission and reducing interference.

The AV-HK1 HUM KILLER is equipped with two adapter cables, making it compatible with a variety of audio devices that use mini-plugs and jacks. Whether you're connecting a computer, CD player, cassette player, or other consumer audio product, the AV-HK1 INPUT ensures seamless integration. The OUTPUT is designed to connect to the input of a grounded amplifier or mixer in your audio system, enhancing your audio experience.

Designed with user convenience in mind, the input and output jacks are oriented left (L) and right (R) when facing each end panel. The correct channel orientation is clearly indicated on the front panel of the module, making setup a breeze.

The AV-HK1 HUM KILLER is not just about performance, but also durability. It's a rugged product designed for portable use, but it's equally suitable for fixed installations, thanks to the included mounting bracket.

The AV-HK1 HUM KILLER also includes two adapter cables to interface with consumer audio inputs and outputs that use stereo mini-plugs and jacks. The package includes the Model AV-AC2 Cable Kit, featuring a Dual Phono to Stereo Mini-plug and a Dual Phono to Stereo Mini-jack, each with a length of 8" (20 cm) plus connectors. These cable kits are also available separately from RDL, ensuring you can easily replace a cable if it becomes worn or lost.

In summary, the AV-HK1 HUM KILLER Stereo Audio Isolation Transformer offers a combination of superior audio quality, user-friendly design, and durable construction, making it an ideal choice for both portable and fixed audio setups.
