22Speaker system connections• Connect the speaker terminals with the speakers making sure thatlike polarities are matched (< with < , > with >). Mismatching ofpolarities will result in weak central sound, unclear orientation ofthe various instruments, and the sense of direction of the stereobeing impaired.Speaker Impedance• Speakers with an impedance from 6 to 16 Ω/ohms can beconnected.• The protector circuit may be activated if the set is played for longperiods of time at high volumes when speakers with an impedancelower than the specified impedance are connected.NOTES:• NEVER touch the speaker terminals when the power is on.Doing so could result in electric shocks.• When making connections, take care that none of the individualconductors of the speaker cord come in contact with adjacentterminals, with other speaker cord conductors, or with the rearpanel and screws.Connecting the speaker cords1. Loosen by turningcounterclockwise.2. Insert the cord. 3. Tighten by turningclockwise.Either tightly twist or terminate the core wires.Protector circuit• This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers undercircumstances 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 longperiod which results in an extreme temperature rise.When the protection circuit is activated, the speaker output is cut off and the power supply indicator LED flashes. Shouldthis occur, please follow these steps: be sure to switch off the power of this unit, check whether there are any faultswith the wiring of the speaker cables or input cables, and wait for the unit to cool down if it is very hot. Improve theventilation 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 theunit, switch off the power and contact a DENON service center.Note on speaker impedance• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers withan impedance lower than the specified impedance (for example speakers with an impedance of lower than 4 Ω/ohms)are connected. If the protector circuit is activated, the speaker output is cut off. Turn off the set’s power, wait for the setto cool down, improve the ventilation around the set, then turn the power back on.Cooling fan• The AVC-A1XVA is equipped with a cooling fan to prevent the temperature inside the set from rising. The fan is activatedunder certain usage conditions. It is temperature sensitive, to minimize or prevent audible fan noise.
