Title: Frequency response
Post by: Listens2tubes on February 05, 2014, 03:22:14 AM
My Otari deck has MTR-10 wide gap heads. It can record and play 20-22khz at 15ips IEC equal. How can I get 20hz reproduction from my Eros?

The IEC curve in Eros is 3dB down at 17Hz. Without knowing the inductance of the head it's difficult to say how it will match up with the input of the Eros. Eros is designed for heads with an inductance of 220 mH or higher.

Thanks for the fast reply Dan, I read it the next day but only now thought to reply back.  Finally I will be finishing assembling my Eros. Just wanted to be sure to not have to go back and change anything later. I will call John French and ask him how much trouble it was to set up the heads. He should know the inductance.
