Bruel and Kjaer type 4134 1/2"and 4133 1/2" condenser microphones with cathode follower for use in sound measurement. The capsules are fairly clean, with a little evidence of light dust and I have not touched them for cleaning, nor would I ever. Please see pics. The B&K Instructions and Applications brochure (photocopy) is included here and provides guidance for cleaning the capsule diaphragm, if needed. This manual also includes a lot of information about the microphone measurement system, with descriptions of free-field and diffuse-field response characteristics. Also included is the microphone adapter Unit JJ 2614. The cathode follower includes a 2m cable for attachment to analysis equipment and provides the means of using long cables to attach to the measurement equipment, by lowering the output impedance. These B&K systems have earned their reputation for accurate acoustic and sound measurement applications. Compatible with contemporary measurement equipment. The carrying case is in excellent condition with only light scratches. Please see pics. Units have been tested and work as described. I will pack the case in bubble wrap and ship in a secure box. I prefer USPS over UPS, but can ship either way if buyer requests. Shipping is from Raleigh, NC. Buyer to pay shipping. Estimated shipping is cost is $20, domestic. I shy away from international purchases as shipping costs are so unbelievably high, but I can make an exception if buyer is willing to cover the shipping cost. Thanks for looking and please contact me with any questions. I will do my best to reply in a timely manner. Item sold AS IS due to age.
