POWER SWITCH
After you have connected the unit to a mains outlet, press this switch to turn on power to the unit. -
ST-BY / POWER INDICATOR
A red LED indicates that power has been applied to the unit, but it is on stand-by. Amplifier will be in Stand By mode in absence of input signal. LED colour will change to green once the amplifier is in active mode. -
FAULT
If the amplifier develops an internal fault, this indicator will glow red -
OVER VOLTAGE
In case of excessively high mains voltage above 260V, the amplifier will shut down to protect itself and this indicator will glow red. -
STATUS/CLIP
There are 8 dual colour LED indicators for different inputs. When the output power is 1W or more, the conesponding channel LED will glow green. If the output clips, the colour will change to red. You can turn off the indicator with a switch on rear panel -
Connect the output of a balanced signal source, e.g., DE 4380 to the balanced input socket with a 2 core shielded cable fitted with an XLR male cable connector at one end having the following pin connections: 1= Ground, 2=(Hot), 3=(Cold).
If the signal input is unbalanced, use unbalanced input via RCA connectors. -
Connect the speaker outputs of 8 channels of DE 4380 to the respective speakers.
-
Connect the supplied mains cable supplied to a utility socket capable of supplying 230V 50Hz AC.
-
Switch on the DE 4380 by pressing the power switch on the front panel.
The power led will glow red in colour. This indicates that power has been applied to the unit, but it is on stand by mode. -
Feed audio signal. The power LED colour will change to green. It indicates the amplifier is in active mode. If there is no audio signal for 10 minutes the unit will again go into stand by mode.
-
Check that all speakers are playing.
-
Put the status indicator switch on rear panel in on condition if you want to view the status of each channel.
-
Your set up is ready. Enjoy the music and adjust the volume of respective channels as per your requirement from the DE 4380 processor.You may do finer adjustments and EQ through the processor, say DE 4380
