User manual RANE RPM 2M

[. . . ] Launch the Drag Net application and follow the steps to create a new project and new RPM 2m device configuration. Double-click the Configure Hardware IP shortcut and follow the instructions to set the unit's IP address to be compatible with your computer's Network settings. Tip: If you aren't sure what IP to use, try the address 192. 168. 69. 69 and subnet 255. 255. 255. 0. This finds the default factory address 192. 168. 69. 22 on the RPM unit, without manually setting it. [. . . ] LINK lights solidly when a valid connection to another Ethernet device (e. g. , a PC or network) is detected. 7 10Base-T jack accepts a standard Ethernet cable with a RJ-45 connector. 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. For each Input or Output Euroblock connector: · Connect the (positive) audio line to the `+' terminal. · Connect the (negative) audio line 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. 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). If this is confusing, just leave the digital trim alone (set to 0 dB) and use the mic-pre gain slider to set mic gain. For the best noise performance, only use the digital trim to cut gain. A high-performance line stage is provided that happily accepts the hot +24 dBu signals from professional audio sources all day. When using non-pro -10 dBV audio sources, select the +12 dB line gain level, or for even better noise performance, use the mic pre at the 15 dB setting and set digital trim to -3 dB. When you're hooking up a consumer CD player with a single-ended output (for example) and you really need an extra 6 dB of gain (for a total of 18 dB of front-end gain), set the mic pre to 18 dB. WARNING: when using the mic pre as a low-noise line stage, make sure the phantom power is turned off! Analog Output Stage Analog output is real easy. There is a Digital Trim control located immediately before the D/A converter. [. . . ] 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.
