Denon AVR-5800 Speaker system connections, Speaker Impedance, Connecting the speaker cords

Speaker system 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 sense of direction of the stereo being impaired.

•When making connections, take care that none of the individual conductors of the speaker cord come in contact with adjacent terminals, with other speaker cord conductors, or with the rear panel.

NOTE:

NEVER touch the speaker terminals when the power is on. Doing so could result in electric shocks.

Speaker Impedance

•Speakers with an impedance of from 6 to 16 Ω /ohms can be connected for use as front and center speakers.

•Speakers with an impedance of 6 to 16 Ω /ohms can be connected for use as surround speakers.

•The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower than the specified impedance are connected.

Connecting the speaker cords

1. Loosen by turning	2. Insert the cord.	3. Tighten by turning
counterclockwise.		clockwise.
	Either tightly twist or terminate the core wires.

Connecting banana plugs

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 LED 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.

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 with an 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 set to cool down, improve the ventilation around the set, then turn the power back on.

Cooling fan

•The AVR-5800 is equipped with a cooling fan to prevent the temperature inside the set from rising. The fan is activated under certain usage conditions. It is temperature and volume level sensitive, to minimize or prevent audible fan noise.
