When a person switches a tape machine's signal electronics cards between NAB and CCIR, what actually happens? Someone recently told me that I can switch my M79 from NAB to CCIR at 15 just by using a CCIR alignment tape.
Is this true?
NAB - CCIR at 15ips
2No it is not.
At 15 IPS, there are two popular eq standards you can choose from. The audio goes through filter networks on its way to, and back off tape. These filters attempt to compensate for the natural bandwidth irregularities that come with recording on tape. There is usually some way to switch this on a machine, either by an actual switch, or by replacing components on the audio channels.

3Thanks!
That's how I had understood it but I thought maybe I was totally wrong.

4There are jumpers on each of the M79 audio cards that allow you to do NAB or CCIR. Can't visualize them right off the top of my head, but look at the schem. Then you can get yourself a CCIR mrl and off you go!
