Signature 2.0

•PGM Content describes the number of surround channels encoded in the disc or broadcast being received.

3/2.1 indicates that the source is a full 5.1 channel signal, with three channels of front (left/center/right) information, two channels of discrete surround information and one channel of dedicated low-frequency effects (LFE) information. This last channel is the “1” often referred to in 5.1 surround. The reason it is described as “1” is that although the LFE channel is fully discrete and separate from the other five main channels, it is restricted to low-frequency information only, and is thus not considered a “full” channel.

3/1 indicates conventional matrix surround programming that is delivered digitally. The “3” refers to the front three channels (left/center/right), while the “1” is the single monaural surround channel. This is the same process used for con- ventional analog Dolby Pro Logic decoding.

2/0 indicates a standard two-channel stereo program with no encoded surround information.

1+1 indicates a program that is encoded to play back in the “dual mono” mode. This means that there is no stereo information recorded in the program. The same monaural signal will be heard from both the front left and front right speakers when 1+1 is shown as the PGM Content.

•Matrix Encoded shows a “Yes” when paired with a 3/1 on the PGM Content line to indicate that the program sources have surround information encoded in the left and right channels. When you see a “Yes” on this line the best surround field will be reproduced by selecting Dolby Pro Logic as the surround mode.

•Sample Rate displays the actual sample

rate used to create the digital audio. 48kHz is the normal sampling rate for Dolby Digital audio signals on DVD discs and HDTV broadcasts.

•Data Rate displays the speed with which digital data is transferred from the source player to the 2.0’s digital decoder. A 384kb/second is the typical data rate for 5.1 DVD discs, but some discs may have

a higher or lower data rate depending on the number of channels encoded, the running time of the disc and the quality of the audio.

When there is a mismatch between the selected surround mode and the incoming signals that prevents the 2.0 from processing the signal as requested, it will automatically select the best possible mode and display it as part of the information on the AC-3 Info screen (Figure OSD-27).

Tuner Operation

The Signature 2.0 features an FM Stereo/AM tuner with the RDS data system to make it easier to identify the type of programming broadcast by FM stations. Stations may be tuned manually, directly, assigned to one of thirty preset locations and recalled in a number of different ways.

Tuner and Frequency Band Selection

To select the tuner as an input source, press the Tuner button g on the remote. The tuner may also be selected by pressing either Source Selector buttons

3on the front panel until Tuner appears in the front panel Information Display. When the tuner is selected the on-screen display will briefly display the frequency and band of the last station tuned, the preset number of the station, if any, and the current surround mode (Figure OSD-17). The front panel Information Display will first show the surround mode and the Tuner source indication for a few seconds (Figure FPD-10) and then switch to a display of the station’s frequency and band, and the preset memory, if any.
