Question | Answer |
What do we call the smallest possible permanent magnet? | Domain |
What do we call magnetism passed from an inner layer of tape to the next outermost layer? | Print thru |
Name the effect that occurs when all domains are polarized at a given instant: | Saturation |
How should we store a reel of tape? | Tails out |
What is tails out storage? | Tape stored on take-up reel |
How is tails out storage indicated? | Blue hold down tape |
What is tapes magnetic coating called? | Oxide |
What occurs when oxide is unevenly distributed? | Drop-outs |
What should be done before putting tape on a tape machine ahdn when changing reels? | Clean the machine |
What does a demagnetizer do? | Returns domains back to random state of magnetization |
What is another name for a demagnetizer? | Degausser |
What reels monitor is on the machine's right side? | Take up reel |
What rees monitor is on the machine's left side? | Supply reel |
What motor is responsible for moving the tape at a constant rate of speed? | Capstan |
On most machines, what clamps the tape to the capstan in play mode? | Pinch roller |
What do we call the system that moves the tape with constant speed and tension? | Transport |
What part of the tape machine returns previously magnetized domains on tape back to a more random state, using an ultrasonic signal? | Erase head |
What must be monitored during overdubs and punch-ins so new performances aren't recorded late? | Sync (Record Head) |
Which head is monitored during mixdown for best quality playback? | Repro head |
Which head magnetizes previously randomized domains to represent the input signal to the machine? | Record head |
In addition to recording, the record head performs another function: what is it? | Sync/playback |
Name the three heads, in order of appearance from left to right (as viewed from front of machine) | Erase, Record/Sync, Repro |
What allows to control machine functions from a place away from the tape machine? | Autolocator |
What head works automatically with the record head to remove previously recorded material? | Erase head |
What do we call magnetic energy from one track that is picked up by a neighboring track? | Crosstalk |
What do we do prior to alignment? | Clean the machine |
Where do we get the test tones used in playback alignment? | MRL Tape or Client Tones |
Where do we get the tones for record alignment? | Record pad |
What tone is used for all level adjustments? | 1 kHz |
What tone is used for all high freq. EQ and bias adjustments? | 10 kHz |
What tone is used for all low freq. EQ adjustments? | 100 Hz |
How many dB above 0dB magnetic reference level is 185 nW? | 0 dB |
How many dB above 0dB magnetic reference level is 250 nW? | 3 dB |
What steps' purpose are so that 0dBVU is a known level of magnetism in playback? | Repro level & sync level |
What steps' purpose are for flattest high freq. response in playback? | Repro high freq. EQ & sync high freq. EQ |
What steps' are for flattest low freq. response in playback? | Repro low freq. EQ & sync low freq. EQ |
What steps are postponed in playback when using MRL? | Repro low freq. EQ & sync low freq. EQ |
What is the difference between the MRL tape and client tones? | MRL tape is used for first alignment procedures. Client tones are used for all subsequent alignments with that client. |
What do we call the section of the tape on the client's reel that we use to perform record alignment? | Record pad |
Where should the record pad be located? | Tail of the tape |
What step in alignment allows a low level signal to be recorded with minimum distortion (overcomes inertia)? | Bias |
How do we calculate what meter settings for playback we should use when test tape and level desired aren't the same? | Test tape level - desired level = meter setting |
We want a +5/185 nW alignment, our MRL is a 250 nW tape: what level should we set for playback? | -2 = (3-5) |
We want a +3/185 nW alignment, our MRL is a 250 nW tape: what level should we set for playback? | 0 = (3-3) |
