Features Center-Field Technology

"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.

Features:

  • Velocity ribbon element featuring Center Field Technology
  • High quality 30ft. right angle 3-pin XLR (F) to straight XLR (M) microphone cable
  • Jewelers quality wood box with two heavy-duty polished nickel latches and hinges
  • Upgrade aluminum case
  • Micro-fiber cleaning cloth

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).
  • A pop-filter is recommended for vocals or any instrument that produces air-pressure.
