Product description

• Shure SM7B Vocal Microphone
  • Mic Shootout 3: Dynamic Microphones
  • Shure Mike's "Ultimate Chopper Drop Test
  The Shure SM7B Vocal Microphone is a dynamic microphone with a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications.
  
  It features a cardioid polar pattern, bass roll-off and midrange emphasis (presence boost) controls, and shielding against broadband interference. An internal air suspension shock isolation helps to eliminate mechanical noise transmission and a yoke mount facilitates mounting and provides precise control of the mic position.
  Flat, Wide-Range Frequency Response
  • The flat-frequency response enhances the midrange and high frequencies that are associated with the human voice.
  Rejection of Electromagnetic Hum
  • Improved rejection of electromagnetic hum, optimized for shielding against broadband interference emitted by computer monitors.
  Air Suspension Shock Isolation
  • Internal air suspension shock isolation virtually eliminates mechanical noise transmission.
  Pop Filter
  • The built-in pop filter eliminates the need for any add-on protection against explosive breath sounds, even for close-up vocals or narration.
  Cardioid Polar Pattern
  • Cardioid polar pattern effectively isolates signal source improving gain before feedback.

• dbx 286s - Microphone Preamp/Channel Strip
  • Mic Shootout 3: Dynamic Microphones
  • Shure Mike's "Ultimate Chopper Drop Test
  The 286s from dbx is a full featured channel strip that includes a studio quality microphone/instrument preamplifier, and four processors that can be used independently or in any combination. The hassle of patching together multiple processors for use on one track can be frustrating. The unit delivers the entire microphone processing chain needed in a single box, with the shortest, cleanest signal path. Features include wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter to remove low frequency hum, rumble or wind. The dbx OverEasy compressor can transparently smooth out uneven acoustic tracks, or deliver the classic "in your face" vocal performance. Vocal sibilance can be tamed or even eliminated and high frequency distortion removed from instruments such as cymbals with the frequency tunable De-Esser. The Enhancer provides both HF Detail and LF Detail controls that can add sparkle and crispness to vocals, while making adjustments to the low frequencies for adding fullness and depth to vocals and bass instruments. Muddy low midrange frequencies can be cleaned and the separate threshold and ratio controls on the Expander/Gate allow for subtly reducing headphone leakage, or radically gate noisy guitar amplifiers. The channel strip provides a full complement of metering and status LEDs. The XLR microphone input accepts balanced or unbalanced inputs, allowing for easily connecting professional or home studio microphones. The 1/4" TRS line input can accept balanced/unbalanced signals to process live electronic instruments or pre-recorded tracks at mix-down, while an insert jack provides access to the signal flow between the preamp and the processing sections for connection to external processors.
  • Studio quality microphone preamp/channel strip processor

• Auray BAI-2X Two-Section Broadcast Arm with Internal Springs and Integrated XLR Cable
  • Mic Shootout 3: Dynamic Microphones
  • Shure Mike's "Ultimate Chopper Drop Test
  The Auray BAI-2X is a two-section broadcast arm with internal springs and an integrated XLR cable. This versatile and sturdy broadcast arm is great for studio as well as home use. It's ideal for broadcast, voiceover, and podcasts.
  
  The BAI-2X broadcast arm is designed with internal springs that provide a clean and sleek look. The internal balance springs are precision engineered to support and hold in place microphones of up to 5 lb. (2.27 kg). The design also minimizes handling noise when re-positioning the arm. The broadcast arm features a standard 5/8"-27 microphone stud mount that is compatible with most shockmounts and microphone clips. The angle of the microphone stud mount can be adjusted and secured with the locking knob, and the angle is maintained when re-positioning the arm. This eliminates the need to readjust it every time the arm is moved. With an extension of up to 40 inches, and the ability to rotate the arm 360°, the BAI-2X allows for precise microphone placement.
  
  The BAI-2X also features a heavy-duty combo mount that consists of a sturdy C-clamp and a heavy-metal desktop mount. The C-clamp is capable of fastening onto desktops up to 2.3" thick. The C-clamp's slim design minimizes the clearance needed to mount it between a desk and wall. The desktop mount detaches from the C-clamp and provides the option of permanent installation to a desktop with the mounting screws (included). A 14" riser is included for adding height to the broadcast arm in order to extend over computer or studio monitors.
