User manual RANE AM 2

[. . . ] First try moving the mics farther from the loudspeaker and/or pointing the mics and loudspeakers away from each other. If this does not reduce feedback, don't reach for the black Mic Input knobs, instead turn down the OUTPUT LEVEL. Daisy-chain up to eight AM2s together by connecting CASCADE IN to CASCADE OUT. The Main Output on each AM2 delivers a gain-sharing automix of it's Mic Inputs and all upstream Inputs. [. . . ] The RAD PORT connects to a Rane Mongoose's Remote Audio Device port to transport the singlechannel, Main Mix of the AM2 to a CobraNet network or another Remote Audio Device. 6 MAIN OUTPUT XLR connector contains the main mix of all mics from this AM2, and all mics from preceding AM2s, if they are connected using the CASCADE ports. The front panel OUTPUT LEVEL control adjusts the level exiting this jack. MIC/LINE Output switch changes this Main XLR Output to mic-level, for feeding the output mix to a mic input device; or line-level for feeding line-level input devices. 7 3-position MIC/LINE switches support 48 volt phantom power Mic position for condenser mics, zero volt Mic position for dynamic mics, and the Line position intended for wireless mic receiver outputs. Each switch controls a pair of mic inputs, as indicated by the rear panel grouping of two jacks for one switch. 8 MIC INPUTS 1 thru 8 accept dynamic or condenser microphones, or the output of a wireless microphone receiver. These inputs are optimized for speech and have a fixed 100 Hz low-cut and 7 kHz high-cut filter. Both filters are 2nd-order Butterworth filters. MIC +48V MIC +0V LINE FAULT USB DATA IN AM2 THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES FOR A CLASS 'B' COMPUTING DEVICE. 24 VDC @ 100 mA CASCADE OUTPUT 8 7 6 5 MIC INPUTS 4 3 2 1 Manual-3 CONNECTION Connect the AC power cord last to avoid loudspeakers hurting your sensitive ears. Unbalanced mics or wiring can also be used with their inherent lower quality and higher potential for hum and noise. Standard microphone cable with a two-conductor twisted pair plus a shield is best. Rane follows the AES recommended practice of pin 2 positive (hot), pin 3 negative, and pin 1 to shield. If your microphone is unbalanced (only two conductors), see the Sound System Interconnection RaneNote elsewhere in this manual or on Rane's website for the proper cable to use. For condenser microphones which require phantom power, use the MIC +48V switch position. Connect the Main Output XLR using mic cable to your amplifier or powered loudspeaker and select the LINE position on the adjacent switch. If the Main Output feeds a microphone snake or mic input, select the MIC switch position. USB DATA PORT Check the AM2 page on Rane's website for potential firmware updates at www. rane. com/am2. html If there is an update, follow the instructions on our website. When using the AM2 with Mongoose Tracker software, AM2 firmware is always kept up to date via the AM2's RAD PORT. RAD PORT If your audio system delivers the AM2's Main Output audio mix using Rane's digital audio transport technology exiting the RAD Port, connect a shielded Ethernet patch cable to the RAD Port. When the Rane Mongoose at the other end of this connection recognizes the AM2's RAD Port, audio nirvana is achieved and all four adjacent RAD Port Status indicators illuminate. CASCADE IN / OUT PORTS Connect a shielded Ethernet patch cable from the CASCADE IN port to another AM2's CASCADE OUT port to add more mics to the mix of this AM2. All four CASCADE IN Status Indicators illuminate when the two devices recognize each other. Connect up to seven more Rane AM2 Automixers for a total of 64 gain-sharing mics. [. . . ] If this indicator is off, either the cable is bad, or there is a communications error between the devices (see COMM LED below). AUDIO Rx LED ­ lights green when the RAD Port successfully receives audio from the Mongoose or cascaded AM2. If this indicator is off, you may have a bad cable, or the device at the other end of the cable is not powered or connected. COMM LED ­ lights green when communication is established between the Mongoose or a cascaded AM1 or AM2. [. . . ]
