17 PRIO
Display field for the indication of an active priority mode related to MIC/LINE channels (levels 2, 3 and 4). Three situations cause the priority feature
of the MIC/LINE channels to engage, thereby causing the PRIO display field on the front of the device to light up yellow:
1. The VOX switching circuit is active (input signal level from channel MIC/LINE 1 exceeds the VOX threshold).
2. Contact between C and + in the terminal block connection of channel MIC/LINE1 is closed using a mute button or switch.
3. Chime tone is being played.
Further information about channel priorities and the display fields EMERG and PRIO, on the front of the device, can be found in the table PRIORITY
LEVELS in these instructions.
EMERG
18
Display field for the priority feature of the Emergency channel. The display field EMERG will light up yellow when priority level 1 is activated by an
emergency VOX circuit or by using an attached mute switch (contact closure). In that moment, all other input channels will be muted. As soon as the
contact closure is opened/disconnected, and when the emergency signal level falls below the set VOX threshold, all channels will be unmuted, and
the EMERG display will be turned off.
STANDBY BUTTON
19
The amplifier can be set to standby mode with a short push of the standby button. This also mutes the loudspeaker outputs. Bring the device out of
standby and back into normal operation by briefly pressing the button again. When standby mode is activated by pressing the standby button, the
amplifier's standby mode cannot be ended by the automatic standby feature, even when an audio signal is present.
STANDBY LED
20
Bicolour LED for displaying operational status. The standby LED lights up white when the device is operational. In standby mode it lights up red.
