OPERATION PCM Audio Playback PCM (Pulse Code Modulation) is the noncompressed digital audio system used for compact discs and laser discs. The digital circuits in the AVR 225 are capable of high-quality digital-to-analog decoding, and they may be connected directly to the digital audio output of your CD or LD player. Connections may be made to either the rear-panel Optical or Coaxial Inputs be or the front-panel Digital Inputs #$. To listen to a PCM digital source, first select the input for the desired source (e.g., CD). Next, press the Digital Input Selector Úp and then use the ‹/› Buttons nq on the remote, or the Selector Buttons 5 on the front panel, until the desired choice appears in the Main Information Display S. When a PCM source is playing, the PCM Indicator A will light. During PCM playback, you may select any Surround mode except Dolby Digital or DTS. If a 96kHz/24-bit PCM signal is detected, the current source input followed by 96k (for example, DVD/ 96k) will be displayed in the Main Information Display S. You may select the Stereo-Digital (Surround Off) mode to process this type of signal. Playback from PCM sources may also benefit from the Logic 7 mode. When playing back a surround-encoded PCM source, such as an LD or surround-encoded CD, use the Logic 7 C (or Cinema) mode. When playing true stereo recordings, use the Logic 7 M (or Music) mode for a wider soundstage and increased rearchannel ambience. NOTE: When a Logic 7 mode is in use with a Dolby Digital 2.0 digital input source, that mode, rather than Logic 7, will be used by the AVR after the digital bitstream is interrupted for any reason, such as stopping or pausing the digital playback. Note, also, that Logic 7 is not available with digital playback unless a twochannel bitstream is in use. Tuner Operation The AVR 225's tuner is capable of tuning AM, FM and FM Stereo broadcast stations. Stations may be tuned manually, or they may be stored as favorite station presets and recalled from a 30-position memory. Station Selection 1. Press the AM/FM Tuner Select Button g on the remote to select the tuner as an input. The tuner may be selected from the front panel either by pressing the Input Source Selector ! until the tuner is active or by pressing the AM/FM Band Selector 9 at any time. 2. Press the AM/FM Tuner Select Button g or AM/FM Band Selector 9 again to switch between AM and FM so that the desired frequency band is selected. 3. Press the Tuning Mode Button @ s to select manual or automatic tuning. In automatic tuning mode, the AUTO Indicator R is illuminated in the Main Information Display Û and the tuner will stop only at those stations that have a signal that's strong enough to be received with acceptable quality. When the Auto Indicator R is not illuminated, the tuner is in a manual mode and will stop at each frequency increment in the selected band. 4. To select stations, press the Tuning Selector Button 8u. When the Auto Indicator R is illuminated, press the button and then release to cause the tuner to search for the next highest- or lowestfrequency station that has an acceptable signal. When tuning FM stations in the Auto mode, the tuner will select only stereo stations. To tune to the next station, press the button again. If the Stereo Indicator P is not illuminated, press the Tuning Mode Button @ s to activate manual mode and tap the Tuning Selector Button 8u to advance one frequency increment at a time, or press and hold it to locate a specific station. When the Tuned Indicator Q lights, the station is properly tuned and should be heard with clarity. 5. Stations may also be tuned directly in either automatic or manual tuning mode by pressing the Direct Button t, and then pressing the Numeric Keys r that correspond to the station's frequency. The desired station will automatically be tuned. If you press an incorrect button while entering a direct frequency, press the Clear Button 28 to start over. NOTE: When the FM reception of a station is weak, audio quality will be increased by switching to Mono mode by pressing the Tuning Mode Button @ s until the Stereo Indicator P goes out. This will also activate the manual tuning mode. Preset Tuning Using the remote, up to 30 stations may be stored in the AVR 225's memory for easy recall using the frontpanel controls or the remote. To enter a station into the memory, first tune the station using the steps outlined above. Then: 1. Press the Memory Button 29 on the remote. The Memory Indicator O will be illuminated and flash in the Main Information Display Û. 2. Within five seconds, press the Numeric Keys r corresponding to the location where you wish to store this station's frequency. Once entered, the preset number will appear in the Preset Number/Sleep Time Display J. 3. Repeat the process after tuning any additional stations to be preset. Recalling Preset Stations • To manually select a station previously entered in the preset memory, press the Numeric Keys r that correspond to the desired station's memory location. • To manually tune through the list of stored preset stations one by one, press the Preset Stations Selector Buttons )` on the front panel or remote. Tape Recording In normal operation, the audio or video source selected for listening through the AVR 225 is sent to the record outputs. This means that any program you are watching or listening to may be recorded simply by placing machines connected to the outputs for Tape Outputs ¢ or Video 1 or 2 Outputs dg 34 35 38 39 in the record mode. When a digital audio recorder is connected to the Optical ‡ or Coaxial ° digital audio outputs, you may record the digital signal using a CD-R, MiniDisc or other digital recording system. NOTES: • The AVR 225 converts analog inputs to a PCM digi- tal signal, enabling you to record the material on a CD or MD recorder connected to one of the AVR 225's Digital Audio Outputs ‡°. The digital recorder must be compatible with the output signal. For example, the PCM digital input from a CD player may be recorded on a CD-R or MiniDisc, but Dolby Digital or DTS signals may not. • Please make certain that you are aware of any copyright restrictions on any material you copy.
