Term
| You can use MRL Calibration Tapes to: |
|
Definition
| standardize mechanical and electronic adjustments of analog audio magnetic tape recorders and reproducers |
|
|
Term
| Most makes and models of pro analog tape recorders are capable of what options of flexibility? |
|
Definition
-can run at several speeds
-use more than one tape width
-EQ standard
-recording level |
|
|
Term
| MRL calibration tapes are designed for: |
|
Definition
| use with various "international interchange standards" and they have test signals optimized for use with various measurement equipment |
|
|
Term
| But I still don't know which MRL Calibration Tape I should use....? |
|
Definition
| the engineer who will use the tape should call Technical Support to help determine the catalog number, then he/she can give the number to his "purchasing agent" to "order from one of our dealers or directly from us" |
|
|
Term
| What standards must you abide by in order to interchange recording with other machines/studios? |
|
Definition
| tape width, speed, track formats, EQ, reference fluxivity, and other mysterious things. |
|
|
Term
| The signal recorded on the tape is called: |
|
Definition
|
|
Term
| describe the magnetic flux's frequency response |
|
Definition
|
|
Term
| The purpose of EQing the recorded flux is to: |
|
Definition
| optimize the dynamic range. This way it decreases with increasing frequency in a standardized way |
|
|
Term
| In order to respond to the recorded flux's EQ, reproducers must |
|
Definition
| have a response that increases with increasing frequency in a standardized complementary way. This will make the reproduced electrical output signal have a flat frequency response. |
|
|
Term
| In addition to EQ, another procedure to deal with uneven frequency response is: |
|
Definition
| a standardized low-frequency boost in recording and complementary cut in reproduction |
|
|
Term
| The best test signals to use for calibrating your tape reproducers depend on these factors: |
|
Definition
| the measurement equipment you have, how long it takes you to make the adjustments and read out the results on your tape reproducers, the level of service work you're doing (major overhaul vs. fine tuning) |
|
|
Term
| What ridiculous number of different test signals are mentioned in the reading? |
|
Definition
| 10. And I don't know if we have to know them or not. |
|
|
Term
| What the hell is the Forth Language? |
|
Definition
| I don't know, but MRL's recording system is computer controlled, and it's programmed in that... |
|
|
Term
| The significance of MRL using the forth language is: |
|
Definition
| They can make you custom test signals... Any sequence of frequencies, levels, and durations you need. |
|
|
Term
| All Multifrequency Calibration Tapes have a ____(a)____ kHz tone at ___(b)____ dB at both ends, which is the _____(c)______ itself. |
|
Definition
a) 1
b) 0
c) reference fluxivity |
|
|
Term
| Most reproducers in the US use a ___(a)______ to measure test signals, but this is only accurate for the signal range of ___(b)____, so in order to use these US multifrequency tapes, you will have to use an external meter with ___(c)___ more sensitivity, |
|
Definition
a) Standard Volume Indicator (VU meter)
b) +3dB to -6dB
c) 10dB more
d) increase your reproducer gain by 10 dB each time you want to use these tapes |
