A single 8 inch (20cm) C-ducer tape microphone is used on the bass or çello. The C-ducer will produce a full round acoustic sound with a high level before feedback. The Tape is positioned over the sound post parallel to the bridge and straddling the centre line of the instrument..
Battery or Phantom Powered C-ducer systems are available for the bass and ‘cello. The unbalanced, battery-powered option is the B1000/8, and the balanced, 48 volt phantom-powered option is the CQM/8.
IMPORTANT: Protecting your Instrument
Non-polyurethane varnishes on old or delicate instruments require special protection before applying the adhesive-backed C-ducer in order to prevent damage on removal. A special low-tack adhesive tape is available on request which should be cut to size and gently laid onto the area of the instrument where the C-ducer tape will be attached. The C-ducer can then be stuck, using our double-sided adhesive tape supplied, onto the low-tack layer, and removed from this area as desired without removing any surface finish from the instrument.
