An interface to record analog signals from DC to 20 kHz on the stereo sound channels of video cassette recorders is described. This interface is an effective solution for the implementation of experiments requiring simultaneous recording of electrophysiological analog data, audio and video signals, since all these data are recorded on the same tape. The system requires the construction of a simple analog interface and minor modifications internal to the VCR, required to bypass non-linear elements present on the audio signal path. The particular solution used to adapt for Sony VCR model SLV-575UC is given in full detail. The general requirements the other VCR makes and models must fulfil to make the adaptation feasible and guidelines for the design of interfaces are discussed.
本文描述了一种用于在盒式录像机的立体声音频通道上记录从直流到20kHz模拟信号的接口。该接口是实现同时记录电生理模拟数据、音频和视频信号实验的有效解决方案，因为所有这些数据都记录在同一磁带上。该系统需要构建一个简单的模拟接口，并对录像机内部进行一些小的修改，以绕过音频信号路径上的非线性元件。文中详细给出了用于适配索尼SLV-575UC型录像机的具体解决方案。讨论了其他录像机型号为使适配可行必须满足的一般要求以及接口设计指南。
