"Balanced Audio Input"
Similar to the ribbon design that was used in the legendary RCA Type 44-BX
Unlike most ribbon motors designed today with an offset ribbon
element the new Cascade 731R houses a hand-tuned dual ribbon element
motor that incorporates the legendary symmetrical ribbon design. This
design offers a true figure 8 pattern. The corrugated aluminum membrane
itself is positioned in the center from front to back, thus producing a
balanced audio input signal to both sides of the ribbon assembly. This
design is very useful when executing a mid-side or Blumlein recording
set-up and also great for live stage use.
The 731R utilizes the same ribbon motor and transformer as the DR-2. The difference is in the radical Deco style frame and body.

Note:
- As with all ribbon type microphones, the 731R is not suitable for
instruments that produce air-pressure, i.e. kick drum or blowing
directly into the grill.
- The 731R Does Not require or want Phantom power (Phantom power can damage the ribbon).
