## Questions & Answers

**Q: Do you make/offer 10mm adapter for the dbx/rational-420 mics?**
A: Thank you for contacting us.
Please see below the manufacturer's reply:  "Unfortunately we do not offer an adapter for the R8090 Sound Calibrator."

**Q: does it works with a dbx rta m?**
A: Here is the reply from the manufacturer: "The R8090 will work with all 1/2" diameter microphones. Doing a quick search online I can see that the "dbx rta m" has a 1.1cm diameter which is 0.433" inch so the size will fit the R8090. For frequency and accuracy the manufacturer recommends to review the Data Sheet"

**Q: has it adapters for 1/4" , 1/2" AND 1" diameter microphones? There is different information on different web pages...**
A: There is also conflicting information in the Instruction Manual for the Reed SC-05 unit, with one page saying that only 1/2" microphones can be calibrated and another that 1/4", 1/2" and 1" can be used.  However, the unit we have will only accommodate 1/2" sound level meters.

**Q: This device comes with an calibration certificate?**
A: Hmm I am not sure. I do not remember seeing any certificate. I do not have the unit with me I have it at work and only used it 2 times when I first receved it. I will try to check on it next week if I can remember to.Thanks
