[. . . ] To disconnect the AC power cord, grasp the plug itself; never pull the cord. · One blade of the plug is wider than the other for the purpose of safety and will fit into the wall outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer. · AC power cord must be changed only at the qualified service shop. Owner's Record This symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

Reproduces the acoustics of a 300-seat live house. Reproduces the acoustics of a 1000-seat concert hall. Reproduces the feeling of a large open-air stadium. Enjoying Surround Sound Ideal for soft acoustic sounds. LARGE HALL OPERA HOUSE JAZZ CLUB DISCO/CLUB CHURCH LIVE HOUSE ARENA STADIUM Ideal for musicals and opera. Great for rock or pop music. Great for sporting events or electric (amplified) music. Be sure to set the game machine to stereo mode when using game software with stereo sound capabilities. GAME Obtains maximum audio impact from video game software. 1) "VIRTUAL" sound field: Sound field with virtual speakers. Notes · The effects provided by the virtual speakers may cause increased noise in the playback signal. · When listening to sound fields that employ the virtual speakers, you will not be able to hear any sound coming directly from the rear speakers. Use the buttons on the front panel to operate the following modes AUTO FORMAT DECODING (Press the A. F. D. The boxes around the letters vary to show how the receiver downmixes the source sound (based on the speakers settings). When using music sound modes like LARGE HALL or SMALL HALL the receiver adds reverberation based on the source sound. The following table shows how the indicators light when using AUTO FORMAT DECODING mode. Although the table below shows almost all of the configurations available from multi channel surround signals, the ones marked " " are the most common.

DIMENSION, VIRTUAL ENHANCED A, or VIRTUAL ENHANCED B) · When using music sound modes like LARGE HALL or SMALL HALL with standard audio formats, like PCM, the receiver creates rear signals from the front L and R signals. In this case, sound is output from the rear speakers, but output channel indicators for the rear speakers do not light. 37 Customizing Sound Fields By adjusting the surround parameters and the equalization of the front, rear and center speakers, you can customize the sound fields to suit your particular listening situation. Once you customize a sound field, the changes are stored in the memory indefinitely (unless the receiver is unplugged for about two weeks). You can change a customized sound field any time by making new adjustments to the parameters. See the table on page 41 for the parameters available in each sound field. Wall type (WALL) Initial setting : midpoint When sound is reflected off soft material, such as a curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound.
