Media player 

 

 

 

 

 

 

 

 

 

UM series mixer-amplifiers are fitted with a built-in media player. This section comprises a Bluetooth receiver, 

USB audio player, FM tuner and AUX input. Pressing the SOURCE select button will step through Bluetooth, 

USB, AUX and FM tuner modes. Pressing the MUTE button for any source will mute the output. 

 

Bluetooth 

 

The Bluetooth function allows connection of a smart phone or tablet to the media player section for playback 

of stored files or streamed digital audio.  

In order to enable this function, it will be necessary to pair the sending device to the receiver as follows. 

 

1.

 

Open the Bluetooth settings menu on the smart phone or tablet (or other sending device) 

2.

 

Scan for Bluetooth devices and look for “adastr

a_

0000” in the list of available devices

 

(ensure that the UM amp is powered on and within reception range) 

3.

 

Select “adastra

_

0000” and the sending device

 should confirm that it is connected as an audio device. 

(note that “0000” may be a different number if i

t has been edited 

 see below) 

4.

 

Play audio from the sending device, ensuring that volume controls are not turned down/muted 

5.

 

Turn up the MEDIA volume control on the amplifier to the required level. 

 

The Previous 

, Next 

 and Play/Pause 



 buttons will operate in Bluetooth as remote playback controls. 

Holding the Previous track or Next track buttons will adjust the output volume of the player down or up. 

 

The Bluetooth name can be customized to enable identification of individual nearby amplifiers. 

To customize the Bluetooth number press and hold the Play/Pause 



 button until adastra_0000 is displayed 

with one of the characters flashing. Press Previous 

 or Next 

 buttons to edit the number and Play/Pause 



 to select another character. Hold Play/Pause 



 to store the ID and exit. 

 

Note: Android devices have the facility to re-name devices within the Bluetooth settings menu.  

If the Bluetooth ID has been re-named on the Android device, editing the Bluetooth ID on the media player 

will not affect the name displayed on that Android device. 

 

FM Tuner 

 

The FM tuner function operates in the same way as a standard FM radio and benefits from the connection of 

an FM 

antenna to the rear panel ‘F’ type connector. 

 

 

If no channels are tuned in, press the Play/Pause 



 button to begin auto tuning, which scans available 

stations and stores them as channels within the FM tuner. Pressing Play/Pause again will abort auto-tuning.  

 

To delete any selected station, press and hold the REPEAT button. 

Repeat the auto tuning process to re-populate any missing presets. 

 

To step through pre-set stations, press the Previous 

 or Next 

 buttons. 

Turn up the MEDIA volume control to hear the output from the speakers and increase to the required level.  

 

Holding the Previous 

 or Next 

 buttons will adjust the output volume of the player.
