Stereo/Mono mode
The default mode for the AMR650-A is stereo, but there are two optional
mono modes:
1. Mono 1 Mode (1 channel mono)
In instances where it is desired to fit only one speaker (ie in a small room
such as a bathroom), the AM650-A (active) speaker can be set to mono
mode, and the AM650-P (passive) speaker not used. The active speaker
then reproduces both left and right signals combined. Starting from the
default jumper positions on the AMR650-A, the CN17 jumper stays on the
RIGHT end pins and the CN14 jumper moves to the LEFT end pins - see
page 7.
2. Mono 2 Mode (2 channel mono)
In instances where two speakers will be installed but due to physical
placement stereo imaging will not work effectively (ie in an L-shaped room
or corridor etc), the speaker pair can be set to mono mode. The speakers
then both reproduce left and right signals combined. Starting from the
default jumper positions on the AMR650-A, move the CN17 jumper to the
LEFT end pins and the CN14 jumper stays on the RIGHT end pins - see
page 7.

Local Source Input
It is possible to install a piece of source equipment to be used local
to the room that contains the AMR650 V2.0. This might be a games
machine or CD player in the bedroom, for example. The are two
ways of connecting a local source:
1. Octopus LIM300 Wallplate
The LIM300 wallplate has a line input and and IR output socket for
IR control of the local source via the AMR650 V2.0. See dedicated
literature for installation instructions. Local Jumper MUST be set to
left and centre pins - see page 7.
2. AMR650 V2.0 onboard local input
A local source can be connected directly to the AMR650 V2.0. IR
control of the source can only be done ‘line-of-sight’ in this case as
the AMR650 V2.0 does not have an IR output. Connection to the
local input socket on the AMR650-A should be via screened audio
cable, terminated at a suitable faceplate. Local jumper MUST be
set to centre and right pins - see page 7.
