Additional Audio/Video Inputs
These inputs enable the unit to receive an audio or video signal from a separate source. There are many different types of connections and ways to accomplish this. Most common are RCA Composite cables and 3.5mm mini-jack plugs.

RCA Composite Inputs
These are your typical red, white, and yellow RCA composite cables that are common among devices with audio and video inputs. The red and white cables are dedicated for audio. The red cable is for the right channel and the white is for the left channel. The yellow cable is specifically for the video signal. Because this type of auxiliary cable contains 2 channels of audio, it will support stereo sound.

This is commonly referred to as a mini-jack or a headphone jack. It is a 3.5mm plug that transfers audio only. There is a right and left audio channel on the plug which allows for stereo sound playback.

3.5mm AV Input
These plugs look similar to the common 3.5mm mini-jack, however they carry a third channel dedicated for video.

This means that an auxiliary input is possible, but only with the use of an optional accessory. These optional adapters will sometimes use the CD Changer port or other port on the back of a unit that might restrict the use of other expandability features. These accessories are typically sold separately.

Rear 3.5mm Audio Input
Headphone Output
If the unit is capable of outputting audio to a pair of headphones, this is the type of jack that makes the connection.
Wi-Fi Antenna
This will allow you to connect to your home network or the internet without having to plug-in an Ethernet cable. The built-in Wi-Fi antenna will connect to the internet without having the computer on.

I listen to the IS9181 every day, it's easy and sounds great

October 19, 2012

I listen to the VTech IS9181 throughout the day. It is wonderfully portable, has great sound, operates with the ease of a traditional radio while offering so much more.

It has been unfaltering in six months of daily use in the garden and the house.
