Clock head
The clock head is a term from audio technology . If an additional track (e.g. instrumental track) is to be added to an existing recording in an analog multi-track production , the artist orients himself during the recording on the audio material already on the tape , which is fed to him via headphones, for example . This sound signal, on which the artist orientates himself, is also called the clock signal . The design-related time offset, caused by the mounting distance between the playback head / earphone (HK) and speaking head (SK) in the tape recorder , prevents the normal earphone from being used for this purpose. In order to be able to work with exact timing , the speaking head is connected for playback - and in this function it is called the timing head .
The clock head is therefore not a further type of sound head (such as speaking and listening heads, also known as recording and playback heads); rather, it is called the analog headset if it is temporarily used as a headset during synchronization. In contrast to combination heads , no attempt is made here to find a compromise between the requirements for hearing and speaking heads in the design. Therefore, the sound quality is clearly audibly worse because the recording head has a narrower gap and during playback, because of fewer wire windings, also emits a lower level than a playback head. During the mixing of a recording, only the normal playback head is used, so that the described quality disadvantage does not normally flow into the mixing .
In 1954 was Les Paul at the company Ampex at their own expense an 8-track tape recorder build. His idea of synchronizing many audio tracks became known under the name Sel-Sync (for selective synchronous), in which a speaking head can record a new track and simultaneously play back previously recorded tracks. This was trend-setting for the future of multi-track recording technology .
