Q: 5. Who makes?

A: This is a genuine Telefunken product.

Q: 6. is this a low noise tube ?

A: I believe it is. I changed out the tube in my preamp before even using it. It is the Telefunken equivalent to a 12AX7 which is a industry standard preamp tube. Telefunken has been in the high end audio tube business for many many years. I just believe this is the best preamp tube available. The tube i had pulled out was supposedly a selected Chinese 12AX7. Although I do not have the measuring equipment to measure any differences, I am completely satisfied with the ECC83.

Q: 7. Is this a low noise mic pre amp tube ?

A: Yes. The Telefunken ECC83-TK black diamond series preamp tube offers cleaner headroom than the typical 12AX7.

Q: 8. What dead cat would work best on these mics? I want it to fully cover the condenser to minimize wind noise.

A: The Rode M5 mics come with a foam windscreen. The recommended dead cat for the Rode M5 is the Rode WS8 (BH #ROWS8).

Q: 9. Can I use the Rode NT5 (matched pair) for choir recording? Thank you.

A: Yes, that is what I am using them for. They sound great even from a distance of 20 feet. This is quite remarkable considering our choir does not face the microphones, but rather face each other. Our choir is located in the back of the church in a balcony. I mounted them on the side pillars and angled them towards the choir.

Q: 10. Do these have balanced matched triodes?

A: Yes they do. They are a matched pair of Telefunken E88CC-TK/6922 Black Diamond Series Vacuum Tubes.
