Spacebar Configurations Detail
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.
The front left and right microphone holder spacing can be adjusted from 6cm to 102cm if
using the E420 105cm bar and 6cm to 50cm E407 53cm bar.
For surround microphone arrays using the SB-SUR system we highly recommend visiting
http://www.mmad.info. This website was created by Michael Williams who has written much
about multichannel microphone array design. It contains an interactive design decision
sequence for tailoring your microphone configuration to your specific acoustic venue. The
underlying theory for this design approach is contained in a series of AES papers written by
Michael Williams.
