Need help?Do you have a question about the Marshall Electronics MXL 990 and is the answer not in the manual?
The MXL 990 is a pressure-gradient condenser microphone designed for various audio recording applications. It is characterized by its 22mm capsule with a gold-sputtered diaphragm and a fixed cardioid pickup pattern. This design makes it highly sensitive, capable of capturing subtle sonic details, but also prone to picking up sounds outside its main pattern, which necessitates careful placement and isolation to avoid feedback.
The MXL 990 functions as a condenser microphone, converting sound waves into electrical signals. Its pressure-gradient design means it responds to the difference in sound pressure between the front and back of its diaphragm, contributing to its detailed sound capture. The cardioid polar pattern is designed to pick up sound primarily from the front, rejecting sound from the sides and rear, making it suitable for isolating a sound source in a recording environment.
The MXL 990 requires phantom power (48V +/- 4V) to operate. Users are advised to ensure that the phantom power on their mixer or separate power supply is switched on if no sound is heard. Due to its sensitivity, experimentation with microphone placement and isolation requirements is recommended, with initial gain settings kept low to prevent equipment or ear damage. The use of a mesh pop-filter or foam windscreen is strongly advised, especially for vocals closer than 3 inches, to prevent moisture from damaging the capsule. The microphone comes with a custom shockmount and a mic stand adapter, along with a carrying case. The shockmount helps to isolate the microphone from vibrations and handling noise. Users should ensure the shockmount's nylon bands are centered and the wire clamp does not rest on the chassis to maintain mechanical isolation. The mount should be slid all the way to the rim of the microphone for a secure hold. The quality of the interconnect cable significantly impacts sound quality, so using the best possible microphone cable is recommended.
To ensure optimal performance and longevity, the MXL 990 should always be stored in its original box to protect it from dust and foreign material, which can degrade its performance over time. It should be stored in a cool, dry place, ideally with the included packet of silica gel to absorb moisture. Preventing moisture from reaching the diaphragm, particularly during vocal recordings, is crucial as it can substantially degrade the microphone's performance. The microphone is covered by a one-year warranty against defects in materials and workmanship from the date of purchase. For any issues, users should contact the company from which they purchased it, providing the original dated sales receipt. Warranty claims require prior authorization from the service department, and coverage is limited to repair or replacement, excluding incidental damages or damage caused by accidental misuse.
