Spacebar Modular
Microphone Positioning System
Precision microphone positioning made simple, reliable and repeatable.
Spacebar microphone positioning systems are designed to make any multi-microphone setup simple and precise. Clearly engraved scales for angle and distance make setting capsule spacing, angle of incidence, and X axis rotation easy and repeatable.
Systems can be purchased in pre-configured assemblies for several standard microphone arrays, or you may build a virtually limitless range of microphone holding structures to meet any need.
All components are precision fabricated from machined aircraft aluminum, brass, and stainless steel. They are light, strong, and if properly cared for will last a lifetime. Components which feature microphone mounts come with American standard 5/8-27 threads, or can be ordered with European standard 3/8-16 Whitworth threads.
Complete technical, setup and maintenance instructions can be found in the spacebar modular manual on our support page.
New SB-SMA-HD Heavy Duty Mic Stand Mount
For 5/8” (16mm) “baby” pin and 1-1/8” (23mm) “junior” socket. Recommended for large multichannel arrays and anytime a lighting stand is used instead of a microphone stand. Included as standard on Immersive Array, optional on Surround Tree and Decca Tree configurations.
Main Spacebar Modular Configurations
Surround Tree
The SB-SUR system allows for mounting of 5 microphones. In its standard configuration three microphones can be mounted as a “front triplet” and two microphones can be mounted as a rear pair. All microphone spacings can be precisely adjusted using the engraved centimeter scales on the bars. Also, all microphone angles of incidence can be precisely adjusted in 5 degree increments. Also available in an HD version with the SB-SMA-HD Heavy Duty Stand Mount Adapter.
Decca Tree
This classic microphone configuration was developed by Decca Records engineers in the 1950s. The Spacebar Decca Tree configuration provides a simple, precise, and easy to set up solution for this technique. The standard Spacebar Decca Tree comes with three E420 1 meter tubes, an SB-SMA 5/8”-27 stand mount adapter and three SB-AMH adjustable mic holders. These are configured to provide a 2 meter spacing between left and right microphones and a center microphone 1 meter forward. Since the stand mount adapter can move front to back on the 1 meter tube it should be located at the balance point for maximum stability.
Blumlein
The Blumlein stereo micing technique was pioneered by Alan Blumlein in the 1930s. The Spacebar Blumlein configuration allows for holding two figure-8 microphones on the same vertical axis and at a precise 90 degree angle of incidence. Two types of mic holder are available depending on the microphones being used. For RCA 44 and RCA 77 type mics and their derivatives, the SB-AMHRA holder should be used. Most other microphones can be mounted with the SB-MH standard mic holder.
A unique feature of the Spacebar Blumlein configuration is that the whole vertical assembly can be rotated on a horizontal axis, allowing the mics to be aimed up or down relative to the horizontal plane. This can be very useful when micing and ensemble from above on a tall stand.
AB Stereo
The AB Stereo microphone technique typically uses two omni-directional microphones spaced apart by a distance. The SB-100 configuration is basically a 1M wide stereo bar. With the addition of another E420 tube and a E418 joiner tube, the SB-100 becomes an SB-200 2 meter stereo bar.
SB-3D11 Immersive Array
The SB-3D11 immersive surround microphone array was developed by Grammy award winning Morten Lindberg from 2L. The array makes a 1 meter cube with a 7 channel array at the lower level and a 4 channel array at the upper level. Due to the size and weight of this array it comes with the SB-SMA-HD (heavy duty) Stand Mount Adapter. The SB-SMA-HD can sit on a 5/8” (16mm) “baby” pin or a 1-1/8” (32mm) “junior” socket receiver.
