Operation
that some future digital sources may not be com- patible with the AVR 310.
3.Note that not all digitally encoded programs contain full 5.1-channel audio. Consult the pro- gram guide that accompanies the DVD or laser disc to determine which type of audio has been recorded on the disc. The AVR 310 will auto- matically sense the type of digital surround encoding used and adjust to accommodate it.
4.When a digital source is playing, you may not be able to select some of the analog surround modes such as Dolby Pro Logic, Dolby 3, Stereo, Hall, Theater or Logic 7.
5.When a Dolby Digital or DTS source is play- ing, it is not possible to make an analog record- ing using the Tape ™ and Video 1 or Video
2Record Outputs ∞dg33 . However, the digital signals will be passed through to the digital audio outputs k.
PCM Audio Playback
PCM (Pulse Code Modulation) is the non- compressed digital audio system used for compact discs and laser discs. The digital circuits in the AVR 310 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 ij 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 Select button Ú q and then use the ⁄/ ¤ buttons non the remote, or the Selector buttons 5 on the front panel, until the desired choice appears in the Main Information Display Y.
When a PCM source is playing, the PCM indi- cator A will light. During PCM playback you may select any surround mode except Dolby Digital or DTS.
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 rear- channel ambience.
NOTE: If you have selected Logic 7 C or M as your surround mode for the current listening session, and you are using a digital input, and you have not changed the default surround mode for that input source to the same Logic 7 mode, then you will notice that if the digital signal is interrupted for any reason (such as stopping the source device), upon resumption of the signal, the AVR 310 will use a different surround mode. In fact, the AVR 310 will use whichever mode was set as the default for that source. The factory default for all sources is Stereo mode, unless the receiver detects a Dolby Digital or DTS bitstream.
MP3 Audio Playback
The AVR 310 is one of the first A/V receivers to provide on-board decoding for the MP3 audio format used by computers and portable audio devices. In addition, some new CD players are capable of playing back optical discs that are recorded with MP3, rather than standard CD audio information. By offering MP3 decoding, the AVR 310 is able to deliver more precise conversion of the digital signals to an analog output, along with the benefits of listening to the MP3 audio through the AVR 310’s high current amplifier and the speakers from your surround system, rather than the smaller speakers and low powered amplifiers typically used with computers.
To take advantage of the AVR 310’s MP3 capa- bilities, simply connect the PCM output of a computer’s sound card or the PCM output of a portable digital audio device to either the rear panel Digital Inputs ij or the front panel Digital Inputs #%. As soon as the digital signal is available, the MP3 Bitstream Indicator A will light, and the audio will begin playing.
NOTES:
•The AVR 310 is only capable of playing sig- nals in the MP3 (MPEG 1/Layer 3) format. It is not compatible with other computer audio codecs.
•The digital audio input signal may be either optical or coaxial, but the signal must be in the PCM format. Direct connection of USB or serial data outputs is not possible, even though the signals are in the MP3 format. If you have any questions about the data out- put format from your computer or a sound card, check with the device’s Owner’s Manual or contact the manufacturer’s technical sup- port area.
Tuner Operation
The AVR 310’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 by either pressing the Input Source Selector ! until the tuner is active or by pressing the Tuner Band Selector 9 at any time.
2.Press the AM/FM Tuner Select button g or Tuner Band Selector 9 again to switch between AM and FM so that the desired frequency band is selected.
3.Press the FM Mode button @sto select manual or automatic tuning.
When the AUTO indicator Xis illuminated in the Main Information Display Ythe tuner will only stop at those stations that have a strong enough signal to be received with acceptable quality.
When the AUTO indicator X is not illumin- ated, 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 X is illuminated, press the button for two seconds and then release to cause the tuner to search for the next highest or lowest frequency station that has an acceptable signal. When tuning FM stations in the Auto mode, the tuner will only select stereo stations. To tune to the next station, press the button again. If the STEREO indicator V is not illuminated, 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 W lights, the station is properly tuned and should be heard with clarity.
5.Stations may also be tuned directly by press- ing 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 incor- rect button while entering a direct frequency, press the Clear button 28 to start over.
