Professional Cassette Recorder Features:
Quick Auto - Reverse
Many tape decks have Auto - Reverse. This is a feature which automatically reverses the tape direction during recording or playback. On consumer machines, the tape keeps turning until it reaches the end of the leader. When it can't pull any more, it reverses direction. During the recording process, you will loose the sound during this leader portion of the tape. This is usually about 15-20 seconds of the message.
Many Professional tape decks have Quick Auto - Reverse . These machines have optical sensors which see the leader and reverse directions immediately. Therefore you don't lose any recording time.
Automatic Level Control
A major problem with recording church services is maintaining a high recording level without distortion. The main job of the sound operator is to provide good sound for the people in the room. It is not possible to constantly monitor the room sound and the tape level at the same time. When loud sound is being recorded, such as music or someone speaking close to a microphone, the tape recording level can reach peaks which cause distortion. When someone quiet speaks, the recording level can be too low making it very difficult to hear what is being said. This is a very significant problem if you are using a high speed duplicator to copy tapes, since the problem is accentuated.
Many Professional tape decks have a feature called Automatic Level Control (ALC). When enabled, this helps to maintain a fairly constant recording level regardless of changes in the input level.
Sometimes when using a sound track to play or sing with, the key is wrong for the singer, or it needs to be tuned to an instrument. Consumer tape decks have no way of adjusting this. Many Professional tape and CD players have Pitch Control which allows you to tune the tape or CD to the instruments or singer's key.
Very few consumer tape decks have a Headphone Jack. Most Professional machines do. This can be very useful to monitor the "mix" of sound which is being recorded on tape. It is also very useful to cueing tapes.
