Speaker Output - LD Systems IMA 60 Bedienungsanleitung

AUX OUT
8
The AUX OUT line output with terminal block connection is used to send an audio signal, for example, to an external amplifier, an active sub woofer
or telephone music-on-hold system (terminal block included). With the MUSIC MIX switch, only the signal of the music channel (MUSIC position) or
the sum of all channels (MIX position) can be sent to the output. The AUX OUT line signal is not influenced by the master volume control. It has a
fixed output level.
Please note: In the factory settings, the EMERGENCY signal is routed via an internal jumper to the AUX OUT line output. If this setting needs to be
changed, the device must be opened and the corresponding jumper removed. Please read the information under "JUMPER FOR EMERGENCY SIGNAL
ON AUX OUT" in these instructions carefully.

SPEAKER OUTPUT

9
The speaker output with terminal block connection (terminal block included) enables the use of low impedance speakers with an impedance of at
least 4 Ohm (LO-Z/HI-Z switch in LO-Z position) or 70/100-V speakers (LO-Z/HI-Z switch in HI-Z position). Please refer to the correct assignment of the
terminal block poles (see figure below). The sound of the speaker signal is adjusted using the BASS and TREBLE controls. The total output power of
the connected speakers should roughly correspond to the amplifier power.
STANDBY ON/OFF
10
If the standby function is activated (STANDBY in ON position), the speaker 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, the amplifier automatically starts from the standby
mode and is ready for full use within around 3 seconds (the standby LED flashes white on the front of the device when starting). If the STANDBY LED
is white, the device is ready for use. The LED is lit red in standby mode. In addition, the IMA 60 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: When the auto standby switch is active, the Bluetooth connection status is also analyzed. When a Bluetooth connection with an
auxiliary device (e.g. Smartphone or tablet) is detected and Bluetooth is selected as the signal source, the device is not automatically put in
standby mode.
11 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 the channel volume
control (control 1) on the amplifier. Should the audio signal be distorted, please check the corresponding input level 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 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 (control 2) on the amplifier. Should the audio signal be distorted, please check the corresponding input level on the back of the amplifier
(CLIP LED/GAIN).
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 the signal source, press the button for at least half a second. Activation of the individual signal sources takes place clockwise.
