7. m while the musician is playing When you find a spot where you like the sound try positioning the N8 there and move to taste For solo instruments try placing the N8 a few feet away This will give a very up close and personal sound Set the microphone above or in front of the instrument The height of the mic in relation to the height of the room can have a large impact on the sound When positioning the N8 try aiming the backside towards a complex wall intersection This can capture the reverberation of the room in an interesting way For bass string instruments that are bowed and plucked placing the N8 about a foot away will give you a very nice and defined low end The proximity effect of the N8 can be used to your advantage For instrument sections a good starting point is to place the N8 a few meters away where the musicians have a nice balanced sound Blumlein configuration positioned at a distance of 4 6 meters from a section can capture the sound with a lot depth The N8s can also be used with great results to capture an entire orchestra Try positioning the mic in the same way that you would for sections but from a much further distance Two N8s on a stereo bar facing outwards at 90 degrees can give you a realistic spacial image that will sound like you are standing in front of the orchestra Piano The N8 delivers a great sound as a close up and distant mic on both upright and grand pianos On an grand piano we have fou
8. mps Drum Overbeads Rooms and Percussion When recording drums there are many techniques to capturing the sound of the kit A good starting point is to use the N8s above the kit as a spaced pair Try positioning them a couple of feet above the drummer s head with a few feet of space in between the two mics Make sure to listen to the combined signal summed to mono to catch potential comb filtering that could be caused by out of phase signals A quick technique that can help avoid phase problems is to keep an equal distance between the two overhead mics and the snare or kick drum Another popular technique to record drum overheads is to setup the mics in a Blumlein configuration coincident pair at 90 degree angle above the head of the drummer with each mic pointing in a different direction This will give you a very wide image of the drums that sounds like you are in sitting center stage Both of these techniques also work well for recording the sound of the 7 room The closer that the N8s are positioned to the drummer the more direct sound and less reverb will be captured by the mics Strings Brass and Reed Instruments Because the N8 has equal treble and bass response from a far distance it can be placed almost anywhere without sounding thin Feel free to position the mic both closer and further away than you normally would with a condenser When recording acoustic instruments a good starting point is to walk around the roo
