Preparing Your Receiver Caution: Make all the necessary connections before you plug in or turn on the receiver. Positioning Speakers a L R Midway Point Between Speakers b a=b Normal Listening Point • Surround speakers generally sound best if you position them above ear level. • To avoid picture interference of a nearby TV, use magnetically shielded speaker systems. This is particularly important for the center speaker since it is usually located closest to the TV.
Preparing Your Receiver Connecting Speakers Preparing the Speaker Wires Follow these guidelines when you select and connect speakers. • Only connect speakers that are rated at between 6 and 16 Ohms. • Be sure you properly connect all speakers. Speaker wire consists of two conductors (individual wires) encased in insulation and is usually color-coded or marked with a ridge along one side so you can identify each conductor.

Preparing Your Receiver Connecting the Antennas In many areas, the supplied indoor AM loop and FM antennas provide satisfactory reception. AM Antennas Assemble the supplied AM antenna’s base by swinging the base in the direction of the arrow and inserting the antenna’s bottom tabs into the base’s slot. If the receiver is in a rack or on a shelf and there is no room for the AM loop antenna, use two screws (not supplied) to mount the base on the wall or another location as shown.
Preparing Your Receiver Warning: To prevent injury, read and follow all cautions and warnings that accompany the outdoor antenna. For the best radio reception, use an outdoor antenna. Follow these steps to connect an outdoor FM antenna to the receiver using 75Ω coaxial cable. Note: If your antenna has 300Ω twin-lead cable, consult your local RadioShack store for the correct adapter. 1. Disconnect the supplied FM antenna from the receiver’s 75Ω terminal. FM UNBAL 2.
Preparing Your Receiver Using One Remote Control for More than One Unit Note: When you plug the cable into a component’s CONTROL IN jack, that component’s remote sensor does not function. If you also have an Optimus professional series CD player, VCR, or cassette deck with the OSR mark ( ), you can connect its CONTROL IN jack to the receiver so you can control all of your equipment with a single remote control.
Preparing Your Receiver Using the AC Power Outlet Caution: Do not connect appliances with high power consumption, such as a heater, iron, monitor, or TV, to this AC outlet. Doing so can cause a risk of overheating and fire, and could damage the receiver. Your receiver has an AC power outlet that you can use to power an electronic device, such as a turntable, cassette deck, or VCR. This switched outlet turns on and off with the receiver and provides a maximum of 100 watts.
Basic Operation Warning: To prevent possible hearing loss, turn VOLUME to MIN before you turn on the receiver or change the program sources. After you turn on the receiver or change the program source, adjust VOLUME to a comfortable listening level. The controls on the remote control work the same as the buttons on the receiver’s front panel, though some are labeled differently. Follow these steps to use the receiver. 1. Press POWER to turn on the receiver’s power. 2.
Basic Operation Tuning the Radio Notes: • A class is a group of up to 10 station frequencies. • For weak signals, we recommend manual tuning. Your receiver has four types of electronic tuning — manual, automatic, direct access, and memory. Manual and Automatic Tuning Follow these steps to manually or automatically tune to stations. Note: If none of the tuning buttons on the remote control operate, press TUNER first. 1.
Basic Operation Memory Tuning Notes: • If you store a frequency in a memory that already contains a frequency, you replace the previous frequency. • If your receiver is disconnected from AC power for several days, it loses all the stored frequencies. Memory tuning lets you store up to 30 AM or FM frequencies in three different classes (10 frequencies in each class), then quickly tune to a class and station. Follow these steps to store a station in a memory location using the front panel controls.
Basic Operation Using Headphones To listen with headphones (not supplied), insert the headphones’ 1/4inch plug into the receiver’s front panel PHONES jack. To silence the speakers and listen with headphones without disturbing others, press appears on the display.

After you begin listening, adjust the volume to a comfortable level.
Cassette Deck/VCR Features You can connect two cassette decks to the receiver. Selecting either VCR/ TAPE 1 or TAPE 2 MONITOR lets you hear the playback from the cassette deck you connected to the receiver’s corresponding (VCR/TAPE 1or TAPE 2 MONITOR) jacks.

Press TAPE 2 MONITOR.
Cassette Deck/VCR Features Playing and Recording Video Tapes You can connect two video sources to the receiver. If you connect a VCR to the VCR/TAPE 1 and DVD/TV or LD/SAT audio and video jacks, you can copy video cassette tapes from one VCR to another and monitor the dubbing process. Playing a Video Tape To play a video tape, load the tape into the VCR connected to either VCR/ or LD/SAT. Press the button (VCR/TAPE 1, DVD/TV, or LD/SAT) that corresponds to the jack the VCR is connected to.
Using Advanced Sound Options Your receiver has four special sound options: Dolby Pro Logic Surround, Dolby 3CH Logic, DSP Effect, and Dolby Virtual. These special options enhance the sound from a connected program source. Notes: • To get the full benefit from programs encoded with Dolby Surround Sound, you need a stereo audio/video source. • Dolby Surround does not operate correctly if the signal passes through a graphic equalizer.
Using Advanced Sound Options 5-D Theater 5-D Theater provides clearer and more dynamic sound effects by outputting audio signals through the rear channel to simulate the stereo sound, compared with a standard surround system which provides only monaural signals to the rear speakers. Press 5-D THEATER to turn this feature on/off. DVD 5.1-Channel Input Together with a multi-channel decoder or DVD player with 5.1-channel output, you can feed sound to all five speaker channels.
Using Advanced Sound Options Test Tone Notes: • You must use the remote control to make these sound adjustments. • Use the VOLUME control to adjust the overall sound level. The test tone lets you balance the signal levels between all your speakers. To adjust the levels, see “Center Level” and “Rear Level.” To turn on the test tone, select one of the surround sound modes (PRO LOGIC, or 5.1-CH) then press SURROUND. Then press TEST TONE.
