ENGLISH Easy Setup and Operation Speaker system layout 2 Basic system layout The following is an example of the basic layout for a system consisting of eight speaker systems and a television monitor: Subwoofer Center speaker system Surround back speaker systems Front speaker systems Set these at the sides of the TV or screen with their front surfaces as flush with the front of the screen as possible. Surround speaker systems Speaker connections • Connect the speaker terminals with the speakers making sure that like polarities are matched (< with with >). Mismatching of polarities will result in weak central sound, unclear orientation of the various instruments, and the stereo image being impaired. • When making connections, take care that none of the individual conductors of the speaker cable come in contact with adjacent terminals, with other speaker cable conductors, or with the rear panel. NOTE: NEVER touch the speaker terminals when the power is on. Doing so could result in electric shocks. 2 Speaker impedance • When speaker systems A and B are used separately, speakers with an impedance of 6 to 16 Ω/ohms can be connected for use as front speakers. • Be careful when using two pairs of front speakers (A + B) at the same time, since speakers with an impedance of 12 to 16 Ω/ohms in this case must be used. • Speakers with an impedance of 6 to 16 Ω/ohms can be connected for use as center and surround and surround back speakers. • The protector circuit may be activated if the unit is operated for long periods of time at high volumes when speakers with an impedance lower than the specified impedance are connected. Note on speaker impedance The protector circuit may be activated if the unit is operated for long periods of time at high volumes when speakers with an impedance lower than the specified impedance (for example speakers with an impedance of less than 4 Ω/ohms) are connected. If the protector circuit is activated, the speaker output is cut off. Turn off the unit's power, wait for the unit to cool down, improve the ventilation around the unit, then turn the power back on. Easy Setup and Operation Connecting the speaker cables 1. Loosen by turning counterclockwise. 2. Insert the cable. 3. Tighten by turning clockwise. Connecting banana plugs Banana plug Turn clockwise to tighten, then insert the banana plug. Protector circuit This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers under circumstances such as when the output of the power amplifier is inadvertently short-circuited and a large current flows, when the temperature surrounding the unit becomes unusually high, or when the unit is used at high output over a long period which results in an extreme temperature rise. When the protection circuit is activated, the speaker output is cut off and the power supply indicator flashes. Should this occur, please follow these steps: be sure to switch off the power of this unit, check whether there are any faults with the wiring of the speaker cables or input cables, and wait for the unit to cool down if it is very hot. Improve the ventilation condition around the unit and switch the power back on. If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around the unit, switch off the power and contact a DENON service center. 5 ENGLISH
