Master Volume Control - LD Systems IMA 30 Manual De Usuario

10 STANDBY ON/OFF
When the standby switch is activated (STANDBY in position ON), the amplifier automatically goes into standby mode after 20 minutes of no audio
signal, thereby reducing power consumption. When an audio signal becomes present, standby mode is automatically ended and the amplifier is
once again operational after around 3 seconds (the standby LED blinks white during this startup time). The STANDBY LED on the front of the device
is continuously white when in normal operation. It is red when in standby mode. IMA30 can be manually set into standby mode by pressing the
standby button on its front panel. In that case, the auto-standby mode is disabled, and the unit won't wake up automatically.
Please note: The auto-standby mode switch analyses the connection status of the Bluetooth unit. If it identifies a Bluetooth connection to a
playback device (e.g. smartphone or tablet), and Bluetooth is selected as a signal source, the device will not automatically go into standby mode.
CHANNEL 1
11
Volume control for channel 1 with white SIG (signal) LED and red CLIP LED. If an audio signal is present on channel 1 and the volume is accordingly
increased using volume control 1, the white Signal LED lights up. If the red CLIP LED lights up, signal distortion may result. Reduce the output level of
the playback device or the volume using volume control 1.
CHANNEL 2
12
Volume control for channel 2 with white SIG (signal) LED and red CLIP LED. If an audio signal is present on channel 2 and the volume is accordingly
increased using volume control 2, the white Signal LED lights up. If the red CLIP LED lights up, signal distortion may result. Reduce the output level of
the playback device or the volume using volume control 2.
13
Touch-sensitive control button for selecting the MUSIC channel signal source (Bluetooth module, input with CD icon, input with cable icon). Switch
the signal source by touching the control panel for at least half a second. Activating the respective signal source occurs in a clockwise fashion.
14
Touch-sensitive control button for activating the Bluetooth pairing mode. Pair a Bluetooth playback device (e.g. smartphone, tablet etc.) with the
Bluetooth module by selecting Bluetooth as the signal source (see Item 13). If no playback device is paired or connected to the Bluetooth module,
the Bluetooth icon flashes slowly. Pair a device by pressing the Bluetooth control panel for around 2 seconds, until the Bluetooth icon flashes faster.
The Bluetooth ID is now visible to other Bluetooth devices. Activate Bluetooth on your playback device and search for nearby Bluetooth devices from
its Bluetooth menu. When LD IMA 30 appears under "available devices", select it to automatically pair. When pairing is complete, the Bluetooth icon
on the front of the devices will light up and remain on. The Bluetooth ID is no longer visible to other devices to prevent unauthorised pairing with
the Bluetooth module. Playback on the device can now be started. To disconnect a currently paired Bluetooth device and to set the Bluetooth
module ready to pair again, press the Bluetooth icon for around 2 seconds. Pair the playback device and connect it again by selecting LD IMA 30
from "paired devices" in the Bluetooth menu of the playback device.
MUSIC
15
Volume control for the MUSIC channel with white SIG (signal) LED and red CLIP LED. If an audio signal is present on channel MUSIC and the volume is
accordingly increased using volume control MUSIC, the white Signal LED lights up. If the red CLIP LED lights up, signal distortion may result. Reduce
the output level of the playback device or the volume using MUSIC volume control.

MASTER VOLUME CONTROL

16
The master volume control is used for adjusting the volume of the summed signal of all channels, excluding the EMERGENCY channel. The EMERGEN-
CY channel bypasses the master volume control and its signal is sent directly to the internal amplifier and loudspeaker output. The master volume
control features a display ring with tricolour LEDs. The LED ring is dark when no signal or when only a very weak signal is present at the output. It
lights up white when a signal with a sufficient level is present. When the internal limiter acts, the ring becomes yellow. When the ring becomes red,
protection mode is activated due to a technical problem (e.g. short circuit in speaker cable). The output is muted in protection mode. Switch the
device off. If the technical problem cannot be rectified, please contact an authorised service centre.
