MUSIC
Stereo line channel for the connection of playback devices such as a CD or MP3 player. The MUSIC channel includes a Bluetooth module. RCA sockets
are provided on the back for connecting two stereo line input signal sources (CD symbol or cable symbol). The desired signal source is selected
using a touch-sensitive button on the front of the amplifier. Adjust the volume of the channel using control MUSIC on the front of the device.

LINE OUT
The balanced stereo line output LINE OUT with terminal block connection is used to send the audio output signal to an external amplifier or active
loudspeaker system. Pin assignment:
LEFT +, LEFT -, G
(Ground),
RIGHT +
,
RIGHT -
(terminal block in packaging content).
BASS/TREBLE:
The tone settings of the output signal can be applied by using the BASS and TREBLE controls.
ST/MONO:
The output of the audio signal can either be in stereo (ST) or in mono (MONO). If the switch is set to MONO, the corresponding audio signal
is summed to mono at both outputs LEFT and RIGHT.

STANDBY ON/OFF
If the standby function is activated (STANDBY in ON position), the amplifier is automatically set to standby mode if there is no audio signal for 20
minutes. This reduces power consumption considerably. As soon as there is an audio signal, standby mode is automatically ended and the amplifier
is once again operational after around 3 seconds (the STANDBY LED flashes white on the front of the device when starting). If the STANDBY LED is
solid white, the device is ready for use. The LED is lit red in standby mode. In addition, the device can also be switched to standby mode manually by
pressing the standby button on the front. In this case, auto standby mode is deactivated and the device no longer starts automatically.
Please note: The standby circuit analyses the connection status of the Bluetooth unit. When a Bluetooth connection to an auxiliary device
(smartphone, tablet) is detected, and Bluetooth is selected as the signal source, the device will not automatically go into standby mode.

CHANNEL 1
Volume control for channel 1 with white SIG (signal) and red CLIP LED. As soon as there is an audio signal on channel 1 and volume control 1 is set to
the desired volume, the white signal LED lights up. If the red CLIP LED lights up, the signal may be distorted. In this case, reduce the channel volume
control (control 1). Should the audio signal still be distorted, please check the corresponding input level on the back of the amplifier (CLIP LED/GAIN).
11
CHANNEL 2
Volume control for channel 2 with white SIG (signal) and red CLIP LED. As soon as there is an audio signal on channel 2 and volume control 2 is set to
the desired volume, the white signal LED lights up. If the red CLIP LED lights up, the signal may be distorted. In this case, reduce the channel volume
(control 2). Should the audio signal still be distorted, please check the corresponding input level on the back of the amplifier (CLIP LED/GAIN).
12
MUSIC
Volume control for MUSIC channel with white SIG (signal) and red CLIP LED. As soon as there is an audio signal on 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, the signal may be distorted.
In this case, reduce the output level of the auxiliary device or the channel volume (MUSIC control).
13
Touch-sensitive button for selecting the audio source of the MUSIC channel (Bluetooth module, input with CD symbol, input with cable symbol). To
switch over the signal source, press the button for at least half a second. Activation of the individual signal sources takes place clockwise.
14
Touch-sensitive button for activating the Bluetooth connection (pairing). To connect a Bluetooth auxiliary device (e.g. Smartphone, tablet, etc.)
to the Bluetooth module of the device, select the Bluetooth signal source (see element 13). If no auxiliary device is connected to the Bluetooth
module, this is indicated by the Bluetooth symbol flashing slowly. In this mode, the LD PRE ST1 is not visible to external auxiliary devices. Only
previously connected auxiliary devices can be connected directly to the LD PRE ST1 without activating pairing mode. In order to prevent an
unwanted or unexpected connection, this connection is not established automatically, but must be manually established in the Bluetooth menu of
the auxiliary device (select LD PRE ST1).
