The microphone should not be able to "hear" the speakers, which can cause feedback (squealing or howling)
Repeat this process for microphones or line inputs connected via the MIC/LINE 2 and 3 inputs.
If the VOX feature is enabled, audio playback through channels 4 and 5 will be reduced in volume
automatically when speaking into MIC 1.
In addition to channel and MASTER volume controls, there are BASS and TREBLE EQ controls (7, 8) to adjust
the tone of the overall output. At the 12 o'clock position, these controls apply no effect to the signal (no boost
or cut).
Moving the BASS control clockwise boosts the low frequencies in the audio, whilst moving it anticlockwise will
cut these low frequencies. Likewise, moving the TREBLE control clockwise boosts the high frequencies in the
audio, whilst moving it anticlockwise will cut these high frequencies.
Adjust these EQ controls to suit the type of audio signal or compensate for the room acoustics.
Media player
RM60, RM120, RM240S and RM360S mixer-amplifiers are fitted with a built-in media player. This section
comprises a Bluetooth receiver, USB/SD audio player and FM tuner.
Pressing the SOURCE select button (1) will step through Bluetooth, USB, SD card and FM tuner modes.
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 RM 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 LN5/USB 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.
The Bluetooth name can be customized to enable identification of individual nearby amplifiers.
