Mopidy extension for controlling an Arcam amplifier

Project description

Mopidy extension for controlling volume using an external Arcam amplifier. Developed and tested with an Arcam AVR-300.


Install by running:

sudo pip install Mopidy-Arcam

Or install the Debian/Ubuntu package from


The Mopidy-Arcam extension is enabled by default. To disable it, add the following to mopidy.conf:

enabled = true

The Arcam amplifier must be connected to the machine running Mopidy using a serial cable.

To use the Arcam amplifier ot control volume, set the audio/mixer config value in mopidy.conf to arcammixer. You probably also needs to add some properties to the audio/mixer config value.

Supported properties includes:

The serial device to use, defaults to /dev/ttyUSB0. This must be set correctly for the mixer to work.
The source that should be selected on the amplifier, like DVD, PVR, VCR, CD, FM, AM, SAT, DVDA, etc. Leave unset if you don’t want the mixer to change it for you.
Set to on or off if you want the mixer to make sure that speaker set A is turned on or off. Leave unset if you don’t want the mixer to change it for you.
See speakers-a.

Configuration examples:

# Minimum configuration, if the amplifier is available at /dev/ttyUSB0
mixer = arcammixer

# Minimum configuration, if the amplifier is available elsewhere
mixer = arcammixer port=/dev/ttyAMA0

# Full configuration
mixer = arcammixer port=/dev/ttyAMA0 source=aux


v0.1 (2013-10-05)

  • Initial version for the Arcam receiver; based on a fork from the NAD mixer.

v0.2 (2013-10-29)

  • Now Mopidy will also handle if the volume of the amplifier is changed outside Mopidy. The volume is updated more or less instanyly and any client will get the updated volume when asking for the volume.
