| The Motorola 3412 (full name is Motorola DCT-3412) is a digital-tuner only version of the ]. It is identical to the 6412 Phase III, except that it is unable to tune in analog channels. It is only used on systems that have analog-digital simulcasting (ADS) active. It is about the same width and height as the 6412, but is not as deep (about 11 inches, versus 13 inches on the 6412). | |||

| With analog-digital simulcasting, when you attempt to tune what would normally be an analog channel (normally those with numbers below 100), it will actually tune in a digital subchannel that is a duplicate of the analog channel. The advantage of ADS is the elimination of most interference and noise issues. Also, 10-12 digital channels can be compressed into the space that would normally be used by one analog channel. Over time, analog channels will be dropped, allowing even more digital channels to be added. The drawbacks to digital broadcasting, as always, are the problems with picture quality artifacts due to digital compression. | |||
