User manual AKG DFM 4X4

[. . . ] To avoid hum or interference, route all audio lines, particularly those connected to the microphone inputs, away from power lines of any type. If you use cable ducts, be sure to use separate ducts for the audio lines. Be sure to disconnect the AC adapter from the power outlet before cleaning the equipment!Never use caustic or scouring cleaners or cleaning agents containing alcohol or solvents since these may damage the enamel and plastic parts. [. . . ] Click on "Next" and accept the given setting by double-clicking on "Next" again. To complete the installation, click on "Finish" when asked for. You can now start the software anytime by clicking on "Start/Program/LecNet for AKG". 2 Setting Up your Before starting the program: Software · check that the DFM4x4 is connected to your computer. If it is not, use the supplied RS-232 cable to connect the DFM4x4 to the computer. Prior to all manipulation and interconnection make sure you have equipped all the devices with a unique address, a number between 128 and 256. To change an address, connect only one device to the computer and if using an AS16x12 or AS8, place it in "MASTER" mode. Launch the software at "Start/Programs/LecNet for AKG/LecNet Master Pro" or double click on the shortcut to LecNet Master Pro you might have created on your desktop. The LecNet program will run a check to see which devices are connected to your computer, thus automatically find the DFM4x4 you have linked to your computer. In the "Input Gain" tab you can fine adjust your input gain and set the minimum and maximum values for remote control via the Programmable Inputs. When finished in a tab save your setting in a Preset by clicking on "File/Save Active Setup to Disk File. " to save it on your computer or "Save Active Setup to DFM4x4 Preset" to save it on the DFM4x4. Click on the "Output Gain" tab and set your Output gains as well as the minimum and maximum values for remote control via the Programmable Inputs. The "Master Output" section enables you to apply gain changes to several outputs at the same time. Select the type of filter you want to use from the "Filter Type" list. All filters, except for the ADFE Notch, have adjustable frequencies from 20Hz to 20kHz. The bandwidths of the filters that support adjustable bandwidth are selectable from 0. We advise you to carefully listen to the changes you have made and stop equalizing as soon as the sound is acceptable. Once the room is equalized, set an ADFE and start to turn up the volume to a point where feedback sets in. Three or four fixed ADFEs, after having equalized the room, would still be OK. (Should you need more you may want to check if your problem should not be solved acoustically. If you have some free filters left you can set these up as supplementary ADFEs: Click on the filter. [. . . ] Select the Programmable Input whose current state you want to indicate from the "Prog Input State" list. Note: You cannot assign the same pin to two functions in the same Preset. As with the Programmable Inputs, you can assign a different function to each Programmable Output in each Preset. Each Programmable Input is internally pulled up though a 100K resistor to +5 VDC, so no external pull-ups are necessary. [. . . ]
