Page 14: Chapter 5: Configuring The Amplifier
1) Configuration using presets In case your setup is a pre-defined set solution from AUDAC, a set solution configuration file will be available (*.SOL) whereby all settings for the configuration can be made by uploading the corresponding file to the amplifier. - Page 15 3) Configuring the inputs After the output configuration has been made, the next step is the input configuration. In standard configuration, every output channel is patched with the corresponding input channel (Input 1 to Output 1, ... ). In case this configuration is required for your setup, this step can be skipped. In cases where specific inputs should be assigned to the outputs, the input selection can be made in the settings menu under ‘Settings’...
- Page 16 Chapter 4 Connecting the Amplifier NOTE Make sure the power is switched OFF when any change is made to the connections of the amplifier. Input connections The signal input connections are performed using a balanced XLR and 3-pin terminal block (3.81 mm pitch) connector for every input.
- Page 17 The used speaker connectors are 4-pole types, containing the output signal for the corresponding channel on +1/-1 terminals. The speaker connector for the first (and third for SMQ) channel also contains the output signal for the subsequent channel on +2/-2 terminals. This allows to transfer of two amplifier channels over one four-conductor loudspeaker cable which is fitted with one connector.
- Page 18 +1 and +2 terminals of the channel 1 (or channel 3 for SMQ). When using terminal blocks, connections are made between both + terminals. Selection for bridged output channels is made through software configuration by the user interface which is controllable using the front panel controls.
- Page 19 ATTENTION Do not connect any conventional 100 Volt line transformers directly to the loudspeaker outputs, an integrated decoupling network shall be provided when used in combination with line transformers. Wire up the system The wiring of the system must be done according to the following rules, to guarantee a proper functioning of the system in all circumstances.
- Page 20 Chapter 5 Configuring the amplifier The configuration of the amplifier can be done using the controls on the front panel of the amplifier. A graphical user interface is indicated on the front panel LCD display which guarantees an intuitive and user friendly experience.

Page 21: Main Screen
The main screen gives a fader overview for the output channels of the amplifier. Depending the channels for the corresponding model (two for SMA or four for SMQ), the output level for each channel can be adjusted. On top of the screen, the names of the output channels are shown (OUT 1, OUT 2, …... -
Page 22: Input
Input The input which is linked to every channel can be selected in this screen. Every input signal can be linked to every output channel, using the input selection matrix. Summed inputs for two sequent input channels can be selected too (E.g. Input 1+2). This can be useful when stereo input channels need to be patched to a mono output, or when the amplifier is used in bridge mode. -

reached. After the desired frequency has been selected it can be confirmed by pressing (turns orange) and turning the function dial clockwise to the entire right side where the ‘OK’ word will appear. After pressing again the frequency is confirmed and the next characteristic can be adjusted. If all characteristics are set to the required value, select the ‘BACK’... -
Page 24: Max Level
Output setup >> Max level This function will guarantee that the output level adjustable by the fader on the main screen (which is accessible through user level access) will never exceed a certain value as configured. This gives protection for non-authorized persons when increasing the volume. It can be adjusted within a range of 0 dB (no restrictions) and -70 dB. -
Page 25: Bridge
Pairs of two subsequent channels can be bridged with merged power of both channels obtaining one single channel with double output power. The bridged pairs should always be subsequent channels (OUT 1+OUT2 & OUT3+OUT4 for SMQ). When bridging two channels, only one fader for the bridged channel will be shown in the main screen. -
Page 26: Input Gain
General setup >> Input gain The gain for each individual input can be set in this screen between a range of -16.5 dB and +30.75 dB. After scrolling and selecting the right input, gain can be adjusted through turning the rotary selection dial. - Page 27 After the desired file has been found, it can be loaded by selecting it. Speaker presets are files in *.SPF format which are prepared and provided by AUDAC and containing all parameters for optimal performance and protection for the corresponding loudspeaker.
