3 4

Ventilation — The unit should be situated with adequate space around it so that proper heat ventilation is assured. Allow 10 cm (4 in.) clearance from the rear and the top of the unit, and 5 cm (2 in.) from each side.

- Do not place the unit on a bed, rug, or similar surface that may block the ventilation openings.

- Do not install the unit in a bookcase, cabinet, or airtight rack where ventilation may be impeded.

Objects and liquid entry —Take care that objects or liquids do not get inside the unit through the ventilation openings.

Carts and stands — Whenplaced or mounted on a stand or cart, the unit should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the unit or cart to overturn or fall.

Wall or ceiling mounting —The unit should not be mounted on a wall or ceiling, unless specified in the Operating Instructions.

Electric Power

1 Power sources — Connect this unit only to power sources

specified in the Operating Instructions, and as marked on

the unit.

2 Polarization — As a safety feature, some units are equipped

with polarized AC power plugs which can only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into an outlet, turn the plug over and try again. If it is not still inserted easily into the outlet, please call a qualified service technician to service or replace the outlet. To avoid defeating the safety feature of the polarized plug, do not force it into a power outlet.

3 AC power cord

- When disconnecting the AC power cord, pull it out by the AC power plug. Do not pull the cord itself.

- Never handle the AC power plug with wet hands, as this could result

Power cords should be firmly secured to avoid being severely bent, pinched, or walked upon. Pay particular attention to the cord from the unit to the power socket.

- Avoid overloading AC power plugs and extension cords beyond their capacity, as this could result in fire or shock.

4 Extension cord — To help prevent electric shock, do not

use a polarized AC power plug with an extension cord,

receptacle, or other outlet unless the polarized plug can be completely inserted to prevent exposure of the blades of the plug.

in fire or shock.

5 When not in use — Unplug the AC power cord from the AC

power plug if the unit will not be used for several months or more. When the cord is plugged in, a small amount of current continues to flow to the unit, even when the power is turned off.

Outdoor Antenna

1 Power lines — When connecting an outdoor antenna, make

sure it is located away from power lines.

2 Outdoor antenna grounding — Be sure the antenna system

is properly grounded to provide protection against unexpected voltage surges or static electricity build-up. Article 810 of the National Electrical Code, ANS1/NFPA70, provides information on proper grounding of the mast, supporting structure, and the lead-in wire to the antenna discharge unit, as well as the size of the grounding unit, connection to grounding terminals, and requirements for grounding terminals themselves.

CONNECTIONS

Before connecting the AC cord

The rated voltage of your unit shown on the rear panel is 120 V AC. Check that the rated voltage matches your local voltage.

CONNECTING EQUIPMENT

Jacks and plugs of the connecting cord are color-coded as follows:

Red jacks and plugs : For the right channel of audio signals White jacks and plugs: For the left channel of audio signals Yellow jacks and plugs: For video signals

IMPORTANT

Connect the speakers, antennas, and all other external equipment first. Then connect the AC cord at the end.

The numbers in the illustration below correspond to the following details.

.-+!iq

Insert the plugs fully into the jacks. Loose connections may

produce a humming sound or other noise interference.

CONNECTING SPEAKERS @)

Speaker terminals

Connect front speakers (system A and/or B), a center speaker and surround speakers to the corresponding speaker terminals on the unit:

- the front speaker cords to the FRONT SPEAKERS terminals

- the center speaker cord to the CENTER SPEAKER terminals

- the surround speaker cords to the SURROUND SPEAKERS terminals.

For more powerful bass, connect a sub woofer with a built-in amplifier to the SUPER WOOFER 4 jack.

Speaker impedance

● Front and center speakers

The SPEAKER IMPEDANCE SELECTOR on the rear should be set to the position that matches the impedance value of the front and center speakers. When using 4 ohm speakers, set the selector to 4Q. When using 8 ohm speakers, set the selector to 8Q. Please unplug the AC cord before setting the selector.

● Surround speakers and super woofer

The SPEAKER IMPEDANCE SELECTOR has no effect on the SURROUND SPEAKERS terminals and the SUPER WOOFER Qjack. For the surround speakers and sub woofer, use speakers of 8 ohms or more.

Front speakers

Lift up the terminal flap, inserf the speaker cord lead

into the terminal slot, then close the flap. Check that the cord is connected securely.

Center speaker

——

Connecting + to +, - to - terminals

To get the proper sound effect, the speaker terminals on the unit and the speaker should be connected with proper polarity; the+ terminal on the unit should be connected to the + terminal on the speaker (and – to –).

* Be sure to connect the speaker cords correctly as shown in

the illustration on the right column. Improper connections can cause short circuits in the SPEAKER(S) terminals.

* Do not leave objects generating magnetism near the speakers.

● When using a sub woofer, select the speaker system A (see

page 6). Otherwise no sound can be heard from it.

POSITIONING THE SPEAKERS

Position the speakers to make the most of the Dolby Pro Logic or DSP effect (see “DOLBY PRO LOGIC”).

@ Front speakers

@ Center speaker

Position in the center of the two front speakers. in addition,

position on or below the TV set, if connecting a TV set to the unit.

@ Surround speakers

Place the surround speakers directly to the side of or slightly behind the listening area. Align them horizontally, about 1 meter (3.2 feet) above ear height.

Sub woofer

Surround speakers

● Sound is heard from the surround speakers when the DSP is

set to on.

● Sound is heard from the center speaker mainly when the Dolby

Pro Logic is set to on. Note that when you select the PHANTOM

mode of the Dolby Pro Logic, the center speaker is muted.

(For details, see “DOLBY PRO LOGIC).

Inserting batteries

Detach the battery cover on the rear of the remote control and insert two R6 (size AA) batteries.

R6(’AA)

When to replace the batteries

The maximum operational distance between the remote control and the sensor on the unit should be approximately 5 meters (16 feet). When this distance decreases, replace the batteries with new ones.

Using the remote control

The instructions in this manual refer mainly to the buttons on the main unit. Buttons on the remote control with the same names as those on the main unit can be used as well.

● [f the unit is not going to be used for an extended period of

time, remove the batteries to prevent possible electrolyte

leakage.

● The remote control may not operate correctly when:

- The line of sight between the remote control and the remote sensor in the display window is exposed to intense light, such as direct sunlight.

- Other remote controls are used nearby (those of television, etc.)

● Do not bring the FM antenna near metal objects or curtain rails.

● Do not bring the AM antenna near other external equipment,

the unit itself, the AC power cord or speaker cords, as noise will be picked up.

● Do not unwind the AM loop antenna wire.

CONNECTING AN OUTDOOR ANTENNA

For better FM reception, use of an outdoor antenna is recommended. Connect the outdoor antenna to the FM 75 Q

terminals.
