Media player
The RM4460 mixer-amplifier is 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 "adastra_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 it 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.
