The RDL EZ-HK3 Audio/Video Hum Killer is a high-quality video transformer isolation module. It's designed specifically for use with unbalanced high-impedance audio inputs and 75-Ohm composite video. The device features both input and output connections on gold-plated RCA jacks. Each input jack is electrically isolated from the case itself as well as from the output ground. Each output jack is connected to the rear panel ground-lift switch, which is designed to eliminate hum due to ground loops. Ground loops are common when the EZ-HK3 is installed between a video source, such as a computer or DVD player, and the input of a grounded video monitor or projector in an AV or video system.

Connect the video output from the audio/video source to the composite video input RCA jack

Connect the audio output from the audio/video source to the RCA jacks

Connect the video output to the A/V system or equipment video input

Connect the audio outputs to the A/V system or equipment audio input

The audio and video output cable shields are connected to the EZ-HK3 chassis when the switch

is in the NORM position. In the unlikely event that the EZ-HK3 chassis is mounted to equipment with a different ground from the equipment the EZ-HK3 output is feeding, a ground loop could be produced. This ground loop is eliminated by setting the switch to the LIFT position

Q: 4. Does this lens have a digital zoom AND a digital focus?

A: The Olympus M.Zuiko Digital ED 14-42mm f/3.5-5.6 EZ Lens is designed to zoom by rotating the zoom ring built onto the lens. Lenses do not have digital zoom. Digital zoom is done in the camera you own. You would focus the lens either by using the autofocus feature on your camera by half-depressing the shutter button on your camera when the camera is set to autofocus mode, or when the camera is set to manual focus, then you would physically rotate the focus ring on the lens to manually adjust focus. While there is automatic focus (also called autofocus, or simply AF for short) and manual focus, I have not heard of digital focus. Manual zoom is done physically on the lens; digital zoom is done in the camera.
