Audio/Video Connections
Before connecting your Receiver to your source components 
and speakers, please read through the next few pages which 
will explain all the input and output connectivity that is 
available. The ‘Speakers’ section explains how to connect up 
your speakers to avoid damage to the amplifier and how to 
arrange your speakers for best performance.
General
The inputs are named to make it easier to reference 
connected devices (e.g. ‘ ’ or ‘ ’). They all have the same 
input circuit, so there is no reason why you should not 
connect a different device to any of the inputs. For example, 
if you had two BD players and the AV input was not being 
used, then the second BD player could be connected to the 
AV input. 
When connecting a video source, its audio must be 
connected to the corresponding sockets. For example, if you 
had a satellite decoder plugged into a   video input, the 
audio must be connected to the   audio inputs!
Making Connections
  Take care to place cables as far from any power 
supply cabling as is practicable, to reduce hum and 
other noise problems.
NOTE: For each input, you must set the ‘Video 
Source’ and ‘Audio Source’ settings according to the 
connection type. (see “Input Cong.” on page EN-31)
HDMI Connectors
PVR, UHD, BD, SAT, AV, GAME, STB
Connect the HDMI video outputs of your source equipment to these corresponding HDMI inputs.
OUTPUT (Zone2 – AVR21, AVR31, AV41)
Connect this output to the HDMI video input of your display device. Output1 is compatible with HDMI Enhanced Audio Return 
Channel (eARC). If you have a supported television then sound from the television’s internal tuner (e.g. Freeview, Freesat, 
DVB-T) will be available using the Receiver’s ‘Display’ input.
