ENGLISH
Speaker Connections
When the "Assign Mode" is set to "ALL Z2" or "ALL Z2+Z3", only multi-zone audio is output from the AVR-4810 speaker terminals.
For output in the MAIN ZONE, connect the output from the AVR-4810 pre-out terminal to an external power amp.
Connecting the Speaker Cables
Carefully check the left (L) and right (R) channels and + (red) and – (black) polarities on the speakers being connected to the AVR-4810, and be
sure to interconnect the channels and polarities correctly.
1
Peel off about 10 mm of sheathing from
the tip of the speaker cable, then either
twist the core wire tightly or terminate
it.
2
Turn the speaker
counterclockwise to loosen it.

Insert the speaker cable's core wire to
the hilt into the speaker terminal.

Turn the speaker terminal clockwise to
tighten it.

Use speakers where one speaker has an impedance of 6 ~ 16 Ω/
ohms. When using a speaker with impedance of 6 Ω/ohms to 8 Ω/
ohms, make sure to set the "Speaker Impedance" in the GUI menu to
"6 Ω/ohms" (vpage 42).

Protection Circuit
If the core wires touch the rear panel and the screws etc., or the ±
sides touch each other, the protection circuit will be activated and the
power indicator will flash red at intervals of 0.5 secs.
If the protection circuit is activated, the speaker output is isolated, and
the power supply goes to the standby state. If the power supply is
turned off, after the power supply cord is withdrawn, please confirm
that speaker cable and input cable are connected.
Also, if replaying large sound levels by using a speaker having an
impedance less than that specified (eg, 4 Ω/ohms), the temperature
will rise, and the protection circuit might be activated. The power
supply will go into the standby state, and the power indicator will flash
red at 2 second intervals.
In this case, please switch off the power supply, and wait until the
AVR-4810 has cooled down, and the surrounding ventilation is good.
Even if there are no problems with the surrounding ventilation and
connections, in the event of the protection circuit becoming activated,
due to thinking that the AVR-4810 has failed, please contact DENON
Service center after switching off.
