System Configuration Speaker Selection and Placement The placement of speakers in a multichannel home-theater system can have a noticeable impact on the quality of sound reproduced. No matter which type or brand of speakers is used, the same model or brand of speaker should be used for the left front, center and right front speakers.
System Configuration System Setup Once the speakers have been placed in the room and connected, the remaining steps in the setup process are to program the AVR 320’s bass management system for the type of speakers used in your system, calibrate the output levels, and set the delay times used by the surround-sound processor. You are now ready to power up the AVR 320 to begin these final adjustments. 1. Plug the AC Power Cord · into an unswitched AC outlet. 2.
System Configuration since the AVR 320 memorizes the settings for each input individually, you will need to make these adjustments for each input used. However, once they are made, further adjustment is only required when system components are changed. To make this process as quick and as easy as possible, we suggest that you use the full-OSD system with the on-screen menus, and step through each input.
System Configuration Once the setting is made for 5.1 or 6.1/7.1 operation, the default surround mode for an input should be set. Each of the remaining five lines on the menu (Figure 3) contains the various surround mode categories, and within those menus you may choose one of the submodes. Note that the list of specific sub-modes in some categories will vary according to whether 5.1 or 6.1/7.1 operation is chosen.
System Configuration Speaker Setup This menu tells the AVR 320 which type of speakers are in use. This is important as it adjusts the settings that determine which speakers receive low-frequency (bass) information. For each of these settings use the LARGE setting if the speakers for a particular position are traditional full-range loudspeakers that are capable of reproducing sounds below 100Hz. Use the SMALL setting for smaller, frequency-limited satellite speakers that do not reproduce sounds below 100Hz.
System Configuration • If a subwoofer is connected to the AVR 320, you have the option to have the front left/right “main” speakers reproduce bass frequencies at all times, and have the subwoofer operate only when the AVR 320 is being used with a digital source that contains a dedicated Low Frequency Effects, or LFE soundtrack. This allows you to use both your main and subwoofer speakers to take advantage of the special bass created for certain movies.
System Configuration ** DELAY ADJUST ** CENTER DELAY: 5MS SURR DELAY: 10MS BACK TO MASTER MENU Figure 6 If the Dolby Digital mode is selected, the CENTER DELAY line is where the first adjustment is made. In that case, press the ‹ / › Buttons o 37 until the number calculated using the formula shown above appears in the display. When the CENTER DELAY is entered, press the ¤ Button n once to move to the next line.
System Configuration cedure as many times as necessary to achieve a desired result. In order to prevent possible damage to your hearing or your equipment, we emphasize that you should avoid setting the master volume above 0dB. Manual Output Level Adjustment Output levels may also be adjusted manually, either to set them to a specific level with an SPL meter, or to make fine tuning adjustments to the levels obtained using the EzSet remote.
Operation Surround Mode Chart MODE FEATURES DELAY TIME RANGE DOLBY DIGITAL Available only with digital input sources encoded with Dolby Digital data. It provides up to five separate main audio channels and a special dedicated Low-Frequency Effects channel. Center: 0 ms – 5 ms Surround: 0 ms – 15 ms DTS 5.1 When the speaker configuration is set for 5.1-channel operation, the DTS 5.1 mode is available when DVD, audio-only music or laser discs encoded with DTS data are played. DTS 5.
Operation MODE FEATURES DELAY TIME RANGE HALL 1 HALL 2 The two Hall modes create sound fields that resemble a small (HALL1) or medium sized (HALL 2) concert hall. Delay time not adjustable VMAx Near VMAx Far When only the two front-channel loudspeakers are used, Harman’s patented VMAx mode delivers a three-dimensional sound space with the illusion of “phantom speakers” at the center and surround positions.
Operation Basic Operation Once you have completed the initial setup and configuration of the AVR 320, it is simple to operate and enjoy. The following instructions will help you maximize the enjoyment of your new receiver: Turning the AVR 320 On or Off • When using the AVR 320 for the first time, you must press the Main Power Switch 1 on the front panel to turn the unit on. This places the unit in a Standby mode, as indicated by the amber color of the Power Indicator 3 .
Operation pictures or TV programs bearing the logo of one of the major surround-encoding processes, such as Dolby Surround, DTS Stereo or UltraStereo® may be played in either the Dolby Digital, Dolby Pro Logic II Cinema, DTS Neo:6 Cinema, or Logic 7 Cinema surround modes depending on the source material. To select from the DSP modes (Hall 1, Hall 2, Theater, VMAx Near or VMAx Far), first press the Surround Mode Selector 9k.
Operation on the remote or the Selector Buttons 7$ on the front panel to choose any of the OPTICAL or COAXIAL inputs, as they appear in the Main Information Display Y display indicator BF or on-screen display. When the digital source is playing, the AVR 320 will automatically detect whether it is a multichannel Dolby Digital, DTS source, MP3 or a conventional PCM signal, which is the standard output from CD players.
Operation flash. This is normal and does not indicate a problem with either the AVR 320 or the source machine. The AVR 320 will return to digital playback as soon as the data is available and when the machine is in a standard play mode. • Although the AVR 320 will decode virtually all DVD movies, CDs and HDTV sources, it is possible that some future digital sources may not be compatible with the AVR 320. • Note that not all digitally encoded programs contain full 5.1-channel audio.
Operation Preset Tuning Using the remote, up to 30 stations may be stored in the AVR 320’s memory for easy recall using the front panel 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 35 on the remote. Note that the MEMORY Indicator U will be illuminated and flash in the Main Information Display ˜. switch the front panel Digital Coax Jack Ó from an input to an output by following these steps: 1.
Operation Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjustments have been made and no further adjustments are made for five seconds, the AVR 320 will return to normal operation. The channel output for any input may also be adjusted using the full-OSD on-screen menu system. First, set the volume to a comfortable listening level using the Volume Control ı 40 î. Then, press the OSD Button v to bring up the MASTER MENU (Figure 1).
Advanced Features The AVR 320 is equipped with a number of advanced features that add extra flexibility to the unit’s operation. While it is not necessary to use these features to operate the unit, they provide additional options that you may wish to use. Display Brightness The AVR 320’s Main Information Display ˜ is set at a default brightness level that is sufficient for viewing in a normally lit room.
Advanced Features To change the length of time that the semi-OSD displays remain on the screen, go to the ADVANCED menu as outlined earlier, and press the ⁄/¤ Buttons n as needed, until the on-screen › cursor is next to the SEMI OSD TIME OUT line. Next, press the ‹ / › Buttons o 37 until the desired time in seconds is displayed.
Multiroom Operation The AVR 320 is fully equipped to operate as the control center for a multiroom system with optional remote external infrared (IR) sensors, speakers and power amplifiers. Although some multiroom installations will require the services of a specially trained installer, it is possible for the average do-it-yourself hobbyist to install a simple remote room system.
Programming the Remote The AVR 320 is equipped with a powerful remote control that will control not only the receiver’s functions, but also most popular brands of audio and video equipment, including CD players, cassette decks, TV sets, cable boxes, VCRs, satellite receivers and other hometheater equipment.
Programming the Remote 1. Place the front of the original remote with the code being sent so that it is facing the IR Transmitter Window b on the AVR 320 remote “head-to-head.” The remotes should be between one and three inches apart. 2. Select the button on the remote that you wish to use as the device selector for the codes about to be entered. This may be any of the Input Selectors e. To erase a single learned code from within a single device’s settings, follow these steps: 1.
Programming the Remote Example: To program the Macro 1 button so that it turns on the AVR 320, TV and a Cable Box, follow these steps: • Press the Macro 1 Button 31 and Mute Button 43 at the same time and then release them. • Note that the Program/SPL Indicator c will flash amber. • Press the AVR Selector f. • Press the Mute Button 43 to store the AVR 320’s power on command. • Press the VID 2 Input Selector Button e to indicate the next command is for “TV Power On.
Programming the Remote Notes on Using the AVR 320 Remote With Other Devices. • Manufacturers may use different code sets for the same product category. For that reason, it is important that you check to see whether the code set you have entered operates as many controls as possible. If it appears that only a few functions operate, check to see whether another code set will work with more buttons.
Programming the Remote Reassigning Device Control Selectors Although each Input Selector e is normally assigned to the category of product shown on the remote, it is possible to reassign one of these buttons to operate a second device of another type. For example, if you have two VCRs but no satellite receiver, you may program the “SAT” button to operate a second VCR.
