[. . . ] At last, the channel's volume setting has to be achieved using the corresponding channel control (4). Ideally, volume controls are set to a position somewhere in the area of their center mark (0 dB), leaving you enough reserve for compensating level differences between the audio signals of various input channels. · 5-2 SPECIAL FEATURES OF THE 650 6. SPECIAL FEATURES OF THE 650 6. 1 Using Ducking Control The ducking control allows the unaltered passage of audio signals of prioritized channels (MIC/LINE 1 and / or MIC/LINE 2), while at the same time the audio signals of any other non-prioritized input channels (e. g. background music) are attenuated to a pre-adjustable level value. The background music audio signal fades in smoothly upon finishing the announcement. For using the ducking function, you have to choose a configuration that includes the option PRIORITY OVERRIDE ENABLED for one or both input channels MIC/LINE 1 and 2 (see enclosed information sheet "650 FACTORY CONFIGURATION"). Owning one of the two optionally available interface boards lets you configure the 650 according to your personal requirements. Please keep in mind that the ducking control automatically affects the corresponding output channel(s), to which the prioritized input channel is assigned. Using the gain control for setting the input level of a prioritized channel and while talking into the connected microphone, depending on the channel's routing, you should be able to see one or both yellow ducking-LED's (9) lighting, which indicates that the ducking function has been activated for either output channel (A or B) or for both. Otherwise, re-adjust the ducking control's threshold setting via the Ducking Threshold control (DUCK THR) (5). Turning the control in the counterclockwise direction decreases the set value while turning it clockwise increases the threshold setting. - Select "EXECUTE" in the Windows start menu. - Enter the command "a:\DRM4000 Editor. exe". - Follow the instructions during the installation routine. 7. 3 PC - 650 Connection Check your PC for available COM-ports that are not assigned to any other application. The 650 Editor Software allows choosing between COM1 to COM8. Use a custom RS-232 cable (5-pin D-type, plug-socket, 1:1) for connecting the chosen COM-port on your computer to the RS-232 interface-port on the rear panel of the 650. Before establishing the connection, make sure to switch off the power of both appliances. Otherwise, this could lead to severe hardware damage. 7-1 SOFTW A R E E D ITOR 650 7. 4 Software Description 7. 4. 1 General The DYNACORD 650 Editor software provides an extremely easy and comfortable manner for configuring, controlling and monitoring the 650.
