Speaker Connections
NOTE
Connect so that the speaker cable core wires do not protrude from 
the speaker terminal. The protection circuit may be activated if the 
core wires touch the rear panel or if the + and – sides touch each 
other (v“Protection Circuit”).
Never  touch  the  speaker  terminals  while  the  power  supply  is 
connected. Doing so could result in electric shock.

When using a banana plug
Tighten the speaker terminal firmly before 
inserting the banana plug.

1
Peel off about 0.03 ft/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  terminal 
counterclockwise to loosen it.
3
Insert  the  speaker  cable’s  core  wire  to 
the hilt into the speaker terminal.
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turned off, after the power supply cord is withdrawn, please confirm 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-4810CI  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-4810CI has failed, please contact DENON 
Service center after switching off.
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-4810CI, and 
be sure to interconnect the channels and polarities correctly.
NOTE
Connect so that the speaker cable core wires do not protrude from 
the speaker terminal. The protection circuit may be activated if the 
core wires touch the rear panel or if the + and – sides touch each 
other (v“Protection Circuit”).
Never  touch  the  speaker  terminals  while  the  power  supply  is 
connected. Doing so could result in electric shock.

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”.
When using a banana plug
Tighten the speaker terminal firmly before 
inserting the banana plug.

When the “Assign Mode” is set to “ALL Z2” or “ALL Z3”, only multi-zone audio is output from the AVR-4810CI speaker terminals.
For output in the MAIN ZONE, connect the output from the AVR-4810CI pre-out terminal to the power amp in the other room.

Turn  the  speaker  terminal  clockwise  to 
tighten it.
