This very complete microphone package will outfit your studio with a total of six microphones with differing specialties. It includes 2 MXL 840 microphones, 1 of each of the MXL 860, 870, 880, and 890 microphones, 6 shockmounts, manual for each mic and blue cleaning cloth. With this collection, you can effectively capture virtualy any sound source you are likely to encounter. MXL-840: It has a 22mm capsule and a fixed cardioid pickup pattern. It is excellent for drum overheads, acoustic guitar, and anything with high end detail. MXL-860: This is equipped with an aluminum ribbon transducer which by nature is a bidirectional (figure-8) pickup pattern. A figure-8 pattern will pick up sounds from the front and back sides of the microphone with equal sensitivity while maintaining a large amount of rejection 90° off access. The front of the microphone is indicated by the MXL logo where the audio signal is in-phase while the back side has an inverted phase. Ribbon mics typically have a lower output than condenser microphones and may require a preamplifier with a lot of gain. It is highly recommended to use a preamp with low noise, high gain, and an input impedance of 1500 ohms or greater. It is good for lead or background vocal, voiceovers or electric guitar. MXL870: This is a medium diaphragm side-address vocal mic with a 22mm capsule and a fixed cardioid response pattern. It is a versatile mic, good for acoustic guitar, horns, room, toms, almost anything. MXL-880: This is a wide diaphragm side-address microphone, a classic lead vocal mic, the one that will be responsible for capturing that fantastic lead vocal performance that will make or break your track. It understands its awesome responsibility and responds with the appropriate blend of seriousness and sense of fun. MXL-890: Here is another wide diaphragm side-address microphone that is suited to lead vocal. It is likewise appropriate as a mic for kick drum or toms, and as a room mic.
