User manual RANE RPM 2M

[. . . ] The LINK LED on the rear panel should be lit. If it is not, verify that you are indeed using a crossover cable, not a standard Ethernet cable. Only use a standard Ethernet cable if you are connecting the RPM 2m and a computer indirectly using an Ethernet switch. Launch the Drag Net application and follow the steps to create a new project and new RPM 2m device configuration. [. . . ] 7 10Base-T jack accepts a standard Ethernet cable with a RJ-45 connector. 8 DEFAULT button recalls Preset 1 when pressed. Holding this button while applying power puts the unit into a special codeload mode for updating firmware. Manual-2 Audio Connections As a safety precaution, turn all devices (especially power amplifiers) OFF when making connections. Doing so gives you a chance to find and correct wiring mistakes and prevent damage to your amplifiers, speakers, ears, pets, etc. Analog Inputs and Outputs The RPM 2m has two balanced analog Inputs, two balanced analog Outputs and one AES3 digital Output. XLR and euroblock connectors are both provided for your convenience. Feel free to use either (but not both!) for each Input. Both Output types may be used if desired. For each Input or Output Euroblock connector: · Connect the (positive) audio line to the `+' terminal. · Connect the (negative) audio line to the `­' terminal. · Connect the cable shield to the terminal. For those installations where the RPM 2m internal shieldto-chassis connection causes interference, connect each shield directly to the chassis screw located above each Euroblock connector, keeping the shield wrapped around the audio conductors as much as possible. For optimum Electromagnetic Interference (EMI) immunity, connect the shields at both ends of the cable. See the RaneNote "Sound System Interconnection" for more information on system connections and proper grounding practices. Analog Input Stage Each analog input uses a studio-grade microphone preamp and an independent line-stage input. The input connectors are switched between the mic pre and the line stage by a relay that is controlled by the user interface. The input stage controls gain in large 15 dB steps. The second analog-gain stage makes the fine 1 dB gain adjustments. Gain is optimized for best overload characteristics. If noise performance is of greater importance, then overload performance can be traded for the best noise performance by using microphone gains of 15, 30, 45 and 60 dB. As an example: if the desired mic pre gain is 40 dB, best overload performance is obtained by setting mic gain to 40 dB and setting the digital trim to 0 dB. Best noise performance is obtained by setting mic pre gain to 45 dB and setting the digital trim to -5 dB (this will cut the top-end headroom by 5 dB). [. . . ] Combinations of Preset switches & voltage Level "pots" are possible as long as combined, they do not exceed the eight pins provided. Since you can Group any or all Level blocks in Drag Net's Remote Map, it's much easier to implement a stereo level control since the Drag Net device is burdened with the task of tracking many Levels. You can use this to your advantage when using VIP pins to adjust multiple zones or levels. Since you can place the Level block anywhere within the Drag Net Processing Map, you can Group Level blocks at the input, at the output or anywhere in-between -- just place the Level block where you want it.
