RM Series User Manual 

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 “adastra” in the list of available devices 

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

3.

 

Select “adastra” and the sending device should confirm that it is connected as an audio device 

4.

 

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

5.

 

Turn up the USB/LN5 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 (2, 5) will adjust the output volume of the player. 

 

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 (4) to begin auto tuning, which scans available stations and stores them as 

channels within the FM tuner. Pressing Play/Pause again will abort the auto-tuning. 
To step through pre-set stations, press the Previous or Next buttons.  
Holding the Previous track or Next track buttons will adjust the output volume of the player. 

 

USB/SD player 

 
When a USB memory stick is inserted into the USB port (9) or SD card into the SD slot (3), the USB 

or SD symbol will show in the display and any compressed audio files will start to play automatically. 
The last connected media will take priority. If playback does not start automatically, press the 
SOURCE select button (1) and Play/Pause button (4) to check if the player is set to the correct mode. 
Try Previous track and Next track buttons (2, 5) if the selected track is unable to play. Otherwise, 

check that the audio files are standard compressed type. 
 
Turn up the USB/LN5 volume control gradually to hear the output from the speakers and increase to 

the required level.  
 
Normal playback will read through all tracks on the storage device. Pressing the REPEAT button (7) 

will step through the repeat modes – ONE (repeat current track), rAND (random), ALL (repeat all) 
 
Pressing the Previous track button (2) briefly steps backwards through tracks on the memory device. 
Press and hold this button to decrease the playback volume. 

 
Pressing the Next track button (5) briefly steps forwards through tracks on the memory device.  
Press and hold this button to increase the playback volume. 

 
To pause the current track, press the Play/Pause button (4) and press it again to resume playback. 
The display shows the track number when a track is selected and then elapsed time during playback 

 
To avoid loud pops through the speakers, turn down the MASTER control before powering down.
