To connect a smart phone or other Bluetooth device to the DELTA-50 media player, open the Bluetooth menu on your 

device and search for “PA SYSTEM”. Pair with this ID and connect (re

-name if desired) in order to be able to play audio 

from the Bluetooth device to the DELTA-50.  
 

Pressing the MODE button will select between Bluetooth and USB/SD playback sources. 
(Note: there is also an AUX setting which is not used, since the mixer section has separate line inputs) 
 

Mute, volume and track navigation can be achieved via the media player control panel. Bluetooth pairing is always 
available for a single device so long as the device is within reception range. It may be necessary to re-connect if the 

device has moved out of range and disconnected. 

 

Remote Control 

 
In addition to the panel controls, an infra-red remote control is provided for the USB/SD player which adds some further 
functions to allow greater control over the media player.  
 

To operate, remove the clear plastic tab from the remote to activate the battery. 

 

 

Charging the internal battery 

 

When not in use but connected via the 12Vdc adapter to the mains, if the POWER switch is in the 

off

 position, 

the internal battery will be re-charged from the mains supply. This can be observed by the CHARGE LED which 

lights when charging.
