D Mic PRo Battery fuel gauge 3D Mic Pro is designed for long battery life A pair of 9V Alkaline LP3 battery will power it for 12 hours The two battery fuel gauges A and B indicate the voltages of battery A and B respectively The battery IDs are marked at the bottom left corner of the battery clamps When the 3D Mic Pro is tuned on and both the batteries are within operating voltage range the gauges glow green Battery Id When any battery voltage falls to approximately 7 volt the corresponding battery gauge turns red At this point the microphone may still work for several minutes but you should promptly replace that battery Both batteries are within operating voltage range Battery A voltage is low needs replacement 13 Mounting to a speaker stana You can mount the 3D Mic Pro to any standard speaker stand by using the 3D Mic Pro shock mount This optional accessory allows you to attach the 3D Mic Pro to speaker stand or camera support system equipped with 1 4 or 3 8 20 pitch screw lugs 14 Mounting to a boom pole 3D Mic PRo Can be fitted ona 3D Mic Pro boom pole or any third party boom pole by usinga 3D Mic Pro shock mount The 3D Mic Pro should be hung upside down as shown in the photograph MITRA 3D Mic Boom POLE Hanging the microphone upside down will laterally invert the 3D sound image To correct this connect the 3D Mic Pro left XLR output to the right
