Mopidy-NAD 0.1

Mopidy extension for controlling volume on a NAD amplifier

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
