Touch-sensitive button for activating the Bluetooth connection (pairing). The connection of a Bluetooth auxiliary device (e.g. Smartphone, tablet,
etc) to the Bluetooth module of the amplifier is via the selection of 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 IMA60 is not visible to external auxiliary
devices. Only previously connected auxiliary devices can be connected directly to the IMA60 without activating pairing mode. In order to prevent
an unwanted or unexpected connection, this connection is not created automatically but must be manually created in the Bluetooth menu of the
auxiliary device.
To connect to a new auxiliary device, press the Bluetooth pairing button for around 2 seconds until the Bluetooth symbol flashes rapidly. The
Bluetooth ID is now visible to other Bluetooth devices. Activate the Bluetooth function on the auxiliary device and search for nearby Bluetooth
devices in the Bluetooth menu. When the LD IMA 60 appears under “available devices”, you just need to select it and the connection will be made
automatically. If this process is successful, the Bluetooth symbol is permanently lit on the front of the amplifier and the Bluetooth ID is no longer
visible to other devices. This prevents unauthorized connections to the Bluetooth module. Playback from the auxiliary device can now be started.
If you want to disconnect the connection with a Bluetooth device so that the Bluetooth module can be connected to another device, press the
Bluetooth button again for around 2 seconds. You can then connect the desired auxiliary device via its setup menu in which you select the LD IMA 60
in the Bluetooth menu (connected devices) of the auxiliary device.

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 corres-
ponding 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 control (MUSIC control) on the amplifier.
16
MASTER VOLUME CONTROL
The main volume control is used to control the sum signal of all channels except the EMERGENCY channel. The EMERGENCY channel bypasses the
main volume control, and the signal is sent directly to the power amplifier and the speaker output. The main volume control is equipped with a
ring-shaped, three-color LED display. This LED ring remains dark when there is no signal or only a very weak signal at the output, and starts to light
up as soon as a sufficient signal level is detected. If the internal limiter is on, the ring lights up yellow. A red light indicates that the protection
circuit of the amplifier has been activated due to a technical problem (e.g. short circuit in the speaker cable). In this case, the output is muted. Turn
the device off. If the technical problem cannot be solved, please contact an authorised service centre.
17
PRIO
The indicator for activated priority mode of the MIC/LINE channel (priority levels 2, 3 and 4). The priority function of the MIC/LINE channel is activated
in the following three situations and the PRIO indicator is lit yellow on the front.
1. The VOX switching circuit is active (input signal level MIC/LINE 1 exceeds the VOX threshold value indicated).
2. The contact between poles C and + of the terminal block connections for MIC/LINE 1 channel is closed using a mute switch/button.
3. The chime tone is played.
Further information on the channel priorities and the EMERG and PRIO indicators on the front of the amplifier can be found in the PRIORITY LEVELS
table in these instructions.
18
EMERG
Indicator for the priority function of the EMERGENCY channel. The EMERG indicator is lit yellow if priority level 1 is activated for VOX emergency circuit
or a connected mute switch/button (contact closure). All other input channels are muted during this time. As soon as the contact closure is opened
again or the emergency signal level falls below the VOX threshold value, the muting of all channels is cancelled and the EMERG indicator goes out.
19
STANDBY BUTTON
Briefly press the standby button to put the amplifier into standby mode and mute the speaker outputs. If the standby button is briefly pressed
again, the amplifier is ready for operation again. If standby mode is activated by pressing the standby button, reactivation of the amplifier via the
automatic standby function is not available, even if an audio signal is detected.
20
STANDBY LED
Dual-color LED to indicate the current operating mode. The standby LED is lit white if the amplifier is ready for operation. The LED is lit red in standby
mode.
