User manual RANE AM 2

[. . . ] Once the input gains are set, the AM2 automatically controls the mic mix to avoid feedback. (You won't need to ride these controls. ) Turn on the amplifier/loudspeaker and turn it up about half way. Also turn the OUTPUT LEVEL knob up until the volume is appropriate for your application. If the system feeds back (that horrible squeal), your mics are hearing too much from your loudspeakers. [. . . ] Use shielded Ethernet CAT 5 cable connected from the AM2's CASCADE OUT. 5 One jack, two functions: The CASCADE OUT connects to an AM1 or another AM2's CASCADE IN when combining units for more gain-sharing mics. 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. MIC INPUTS The eight mic jacks are balanced XLR inputs. 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. Dynamic mics use the center, MIC +0V position. When using a wireless microphone receiver, use the LINE position. MAIN OUTPUT The Main Output is a mono balanced XLR jack. 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. [. . . ] 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. [. . . ]
