Making good sound recordings

Dolby Noise Reduction System

Dolby B NR is the system used in most cassette tape decks to reduce the background noise that is inherent in all cassette tapes. Dolby Laboratories then developed an even more effective noise reduction system, Dolby C NR, in response to the demand for increasingly better sound quality from cassette tapes.

Both Dolby noise reductions systems operate by boosting signals during recording that fall below a certain input level.

Dolby B and C NR operate on the higher portions of the fre- quency spectrum using what is called a “sliding band” technique. This is because tape hiss is most prominent during the quiet, high frequency portions of a recording. These same signals are then reduced back to their original strength during playback, thereby reducing the background noise by the same amount. In order to operate only when necessary, the Dolby NR system has a varying effect depending on the input level and frequency of the material being recorded.

Dolby C NR is capable of reducing tape hiss by 10 dB more than Dolby B NR. In addition to its noise reducing function,

Dolby C NR has an anti-saturation network that lowers high input levels before recording them and returns the signals to their original strength during playback. This raises the high-frequency saturation level of cassette tapes to allow you to record signals that would normally cause distortion. This system raises the max- imum output level of cassette tapes by more than 4 dB at 10 kHz.

Setting the Proper Recording Level

The recording level has an important effect on the sound quality a tape will have when it is played back. A recording level that is too high will cause distortion while one which is too low will lower the signal-to-noise ratio resulting in a tape with excessive “hiss noise.” It is particularly important to set the recording level correctly with cassette tapes since they have a much thinner mag- netic coating than open reel tapes. The thin coating gives the tape a comparatively low saturation level which can easily be sur- passed if the recording level is set too high.

The recording level indicators feature a peak-hold function for the indicators from -6 dB through +6 dB. This can come in handy when setting the recording level.

CD Synchro Recording System

Once the TA-RW255 is connected to a CD player bearing the z mark (see page 12), press the s button of the CD player will cause recording to start automatically on the TA-RW255.

1.Insert a cassette with the side to be recorded facing out.

2.Start the CD player.

3.Press the t button to place the unit in the recording standby mode. Adjust the input level. When the recording level has been set, stop the CD player.

4.Start the CD player again, and recording will begin simulta- neously.

Notes:

1.Even if the CD player is stopped during recording, the cas- sette deck will continue recording.

2.If the cassette deck is in the recording standby mode when the CD is put in play, the deck will begin recording. When setting recording levels, always start the CD first.
