![]() You will use this to set playback levels and EQ. ![]() This is a tape, which has been recorded at a known level of magnetism for at least three frequencies, 100 Hz, 1 kHz, and 10 kHz. Thus the tape deck uses a -6 dB per octave low-pass equalization to obtain flat frequency response.Īrmed with this knowledge, we are now ready to match the tape machine's electrical characteristics to the tape we wish to use for recording. On playback, magnetic tape exhibits a 6 dB per octave rise in output. Playback equalization must be applied to compensate for the nature of the medium. Its purpose is to compensate for the characteristics of the recorder and the tape. Recording equalization (set to AES/NAB or IEC/CCIR standards in most cases) is applied before our audio gets to the tape. In analog recording, a built-in EQ is applied at both ends of the process. We all understand the purposes of equalization. There is some low-level intermodulation distortion, however. in pro decks), it doesn't affect the audio being recorded too much. Since the bias frequency is way beyond our hearing range (100- 200 kHz. That shove is provided by high-frequency bias. The tape needs a bit of a shove to get it into the linear part of its transfer function. Well, if the tape's already been erased, you might wonder, why do we need more of the same signal fed to the record head? Turns out that magnetization is not a linear function. The bias oscillator in your analog tape machine serves two purposes: it erases the tape as it passes the erase head, and it provides recording bias, as a smaller amount is sent to the record head. Keep in mind that this is just the tip of the iceberg - there's enough info and tips on this to fill a book - but don't be afraid to learn how to do this yourself - you need this knowledge! Here's how it works: Your recordings will sound better (than if you left it uncalibrated for years!) and you won't be afraid to try new tape formulations or work on tapes from other studios. If you're an engineer working with analog tape decks, you should know how to set decks up for different operating levels, bias for varying brands and formulations of tape, and how to calibrate your deck for a flat EQ response. These radios feature mechanical push buttons, correct color "Roll-Over" dials,and a needle that actually moves when the radio is seeking for a radio station.Bias and equalization you've probably heard and used the terms for years, possibly without really understanding their effect on the quality of your recordings.
