Mopidy extension for controlling volume on a NAD amplifier
Project description
Mopidy extension for controlling volume using an external NAD amplifier. Developed and tested with a NAD C355BEE.
Installation
Install by running:
sudo pip install Mopidy-NAD
Or install the Debian/Ubuntu package from apt.mopidy.com.
Configuration
The Mopidy-NAD extension is enabled by default. To disable it, add the following to mopidy.conf:
[nad] enabled = false
The NAD amplifier must be connected to the machine running Mopidy using a serial cable.
To use the NAD amplifier ot control volume, set the audio/mixer config value in mopidy.conf to nadmixer. You probably also needs to add some properties to the audio/mixer config value.
Supported properties includes:
- port:
The serial device to use, defaults to /dev/ttyUSB0. This must be set correctly for the mixer to work.
- source:
The source that should be selected on the amplifier, like aux, disc, tape, tuner, etc. Leave unset if you don’t want the mixer to change it for you.
- speakers-a:
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.
- speakers-b:
See speakers-a.
Configuration examples:
# Minimum configuration, if the amplifier is available at /dev/ttyUSB0 [audio] mixer = nadmixer # Minimum configuration, if the amplifier is available elsewhere [audio] mixer = nadmixer port=/dev/ttyUSB3 # Full configuration [audio] mixer = nadmixer port=/dev/ttyUSB0 source=aux speakers-a=on speakers-b=off
