You Need The AV-HK1!

The AV-PAK Series is a versatile product group from Radio Design Labs. The heavy-duty metal design allows the
products to be used for both portable or fixed installations. These products feature the dark RDL ULTRASTYLE™
color complement making the modules ideal for use on stage as well as in an office or meeting room.

APPLICATION: The AV-HK1 is a stereo transformer isolation module for use with unbalanced, high impedance audio
inputs. Input and output connections are provided on gold-plated phono jacks. The AV-HK1 is supplied with two
adapter cables to facilitate connecting with products that use mini-plugs and jacks.

The shield connection of each INPUT jack is electrically isolated from the case and from the output ground. The shield
connection of each OUTPUT jack is connected to the case shield. The user audio source, such as a computer, CD
player, cassette player or other consumer audio product, connects to the AV-HK1 INPUT. The OUTPUT should be
connected to the input of the grounded amplifier or mixer in the audio system.

Input and output jacks are oriented left (L) and right (R) when the user is facing each end panel. The correct channel
orientation is indicated on the front panel of the module.

The AV-HK1 is a rugged product designed for portable use. For fixed installations, a mounting bracket is included.
Many consumer audio inputs and outputs use stereo mini-plugs and jacks. The AV-HK1 includes two adapter cables
to interface with these products. The cable kits are also available separately from RDL in the event a cable becomes
worn or lost.

Model AV-AC2 Cable Kit (included with AV-HK1), Includes:

Wherever mono or stereo ground isolation is required for an unbalanced audio input, the AV-HK1 is the ideal choice.
Use the AV-HK1 with other RDL modules and products to form a complete audio/video system.
