Depending on the chosen connection method (low impedance or constant voltage), the output configuration setup
shall be configured accordingly.
Output configuration settings are made in the amplifier menu under ‘Settings’ > ‘Amplifier’ > ‘Output’ and ‘Output
type’. Selection can be done for 100V, 70V, 4
Ω
, 8

and 16
Ω
output types. The correct output setting is important
to make sure all configured limiter settings are working correctly.
2) Connecting the audio sources
The next step is making the input signal connections. Depending on the source type and signal level (microphone
or line), they need to get connected to the matching inputs. Slowly raise the master volume control until the desired
sound level is achieved. Depending of the output level of the connected music sources, the input gain might need
adjustment. Adjust these trimmers on the rear panel until the desired level is achieved.
The best signal to noise ratio is achieved when the master volume control of the amplifier is set near maximum
position and the peak signal indicator is illuminating frequently without illuminating the clip LED indicator. If the
signal sounds too loud or distorted, use the input level controls to attenuate as necessary to achieve the desired
output level.
In case an internal SourceCon™ module is required as audio source, refer to the chapter 5 of this instruction manual.
3) Priority, phantom & muting
The microphone input contains priority (PRIO) and phantom power (PHNTM) dip switches. Enable these switches
according to the connected input sources and project requirements. The phantom power switch enables 15 Volts
phantom power supply for powering condenser microphones and a priority switch eliminates other connected
audio sources once a signal is present on this input. When priority is enabled, this input has overall priority over all
other inputs and also overrides the priority mute. More settings regarding priorities can be made through software
configuring.
The priority mute contact mutes the music at the presence of a contact closure between both terminals.
4) Advanced software configuration settings
Multiple advanced software configuration possibilities are available, depending on project specific requirements.
Configuration is done through the front panel control interface or the AUDAC Touch™ 2 application. All configurable
possibilities can be found in earlier chapters of this instruction manual.
