3. Connections
1. Power supply connector - use the provided power
cord and connect it to a 110V or 220V wall plug. You don’t
need to change any setting, the power supply is universal.
2. RCA Input - These RCA inputs are used with your
external music source. MTX recommends only high
quality RCA cables to decrease the possibility of radiated
noise entering the system.

connected with any optical audio divice. For example,
you can use it with your TV, your DVD/CD/BR player or any
streaming device.

The MTX iWa250 can stream directly from Spotify. Your
iDevice or Android® device becomes “only” a remote control.
It is convenient as it doesn’t drain your battery and you
can leave the room or even the house without any music
interruption. You still can control the tracks (Play, pause,
skip, forward, volume level...) with the iWa250 remote
control.
To use this feature, just download the Spotify app on your
device, register, choose a playlist, an album or some tracks,
and the iWa250 will contact Spotify by itself.
You don’t have to do any special setting. It is transparent for
the user. Only Spotify app is required on your device or on
your compurer. When your are in the app, do not forget to
select the iWa250 as audio output.
Note that Spotify Connect can’t operate when the iWa250
is in “Wi-fi Direct” mode as the unit is not connected to
internet.

1. When the unit is ON, if there is no audio signal
broadcasting on any of the 3 audio inputs, after 15 minutes,
the unit will automatically enter “Networked Standby“
mode. Both LEDs will switch OFF, but the unit will remain
available in the Airplay®/DLNA® network.
2. When the unit is in “Networked Standby“ mode, it will
automatically switch ON if any signal is detected on any input, or if you call the unit from Airplay®/DLNA®.

is 2,9W. If you push the “Power Off” key on the remote control, the unit will be OFF and the power consumption will
be only 0,4W.

without signal on the other inputs.
