LOGITECH HARMONY ONE+ USER MANUAL
Glossary
Activity
An activity is something you do with your entertainment system, like watching TV,
listening to music, or playing a game. With your Harmony remote, you can set up
an activity so that a single button on the remote turns on the necessary devices,
and switches them to the required inputs.
Amplifier
A stereo component that outputs to speakers, and increases the gain or level of
an audio signal. An amplifier doesn’t typically include a radio.
Aspect ratio
The ratio of image width to image height. Common ratios are 1.85:1 and 2.35:1.
Television screens are usually 1.33:1 (also known as 4:3). HDTV is 1.78:1, or 16:9.
AV switch
A device with several audio and video source inputs that sends a selected audio/video
source input signal to an output device like speakers or a TV.
Device
A component in your home entertainment system.
DVD recorder (DVR)
A standalone unit that resembles and functions very much like a VCR. Like a VCR,
DVD recorders all have AV source inputs; as well, it can record TV shows.
Input
Inputs are the connections on the back of your devices. Using these inputs,
you connect your devices to each other.
In sync
The Harmony One+ knows what state all of your devices are in, such as whether
they are on or off and which inputs they were last using. When it loses track
of this information, it becomes “out of sync”. Your remote can send commands
to your devices to become “in sync” again.
IR (Infrared)
Type of signal used by most remote controls. Harmony remotes can control devices
that use IR for remote control.
Mini-system
A single unit that is some combination of the functionality of a DVD, VCR, radio,
and amplifier. Also known as a home theater or home cinema.
