CHANNEL 1
11
Volume control for channel 1 with white SIG (signal) and red CLIP LED. As soon as an audio signal is
present at channel 1 and the volume control 1 is set to the desired volume, the white signal LED lights
up. If the red CLIP LED lights up, distortion of the signal may occur.
In this case, reduce the output level of the source device or the channel volume (control 1)on the
amplifier. If distortion still occurs, please check the corresponding input stage on the back of the
amplifier (CLIP LED / GAIN).
CHANNEL 2
12
Volume control for channel 2 with white SIG (signal) and red CLIP LED. As soon as an audio signal is
present at channel 2 and the volume control 2 is set to the desired volume, the white signal LED lights
up. If the red CLIP LED lights up, distortion of the signal may occur. In this case, reduce the output level
of the source device or the channel volume (control 2) on the amplifier. If distortion still occurs, please
check the corresponding input stage on the back of the amplifier (CLIP-LED / GAIN).
13
Touch-sensitive button for selecting the audio source for the MUSIC channel (Bluetooth module, input
with CD symbol, input with cable symbol). To switch the signal source, touch the key for at least half a
second. The individual signal sources are activated in a clockwise direction.
14
Touch-sensitive button for activating the Bluetooth connection (pairing). The connection of a Bluetooth
accessory device (e.g. smartphone, tablet, etc.) with the Bluetooth module of the amplifier is done by
selecting the Bluetooth signal source (see item 13). If no external player is connected to the Bluetooth
module, this is indicated by the Bluetooth symbol flashing slowly. To connect to an external player,
press the Bluetooth pairing button for approx. 2 seconds until the Bluetooth symbol flashes faster.
Now the Bluetooth ID is visible to other Bluetooth devices. Activate the Bluetooth function of the
external player and search for nearby Bluetooth devices via the Bluetooth menu. When the LD IMA 120
or IMA 240 appears under "Available devices", you only need to select it and the connection will be
established automatically. When pairing is complete, the Bluetooth icon on the front of the device will
light up and remain on. The Bluetooth ID is no longer visible to other devices to prevent unauthorised
pairing with the Bluetooth module. Now playback can be started via the external player. If you want to
disconnect the pairing with a connected Bluetooth device again so that the Bluetooth module can be
connected to another device, press the Bluetooth button again for approx. 2 seconds. You can then
integrate the desired playback device into the setup by selecting the LD IMA 120 or IMA 240 in the
Bluetooth menu ("Connected devices") of the playback device.
MUSIC
15
Volume control for the MUSIC channel with white SIG (signal) and red CLIP LED. As soon as an audio
signal is present at the MUSIC channel and the corresponding volume control is set to the desired
volume, the white signal LED lights up. If the red CLIP LED lights up, distortion of the signal may occur.
In this case, reduce the output level of the source device or the channel volume (MUSIC control) on the
amplifier.
