ISD4002-120P is a device designed to provide an economical solution for recording, selecting, playback and control of voice and other AC and DC signals. This device is part of the interface-voice record and playback category. It combines several features, the most popular of which is its ability to simultaneously record and playback multiple times different signals. Other features include direct access to soundbites, record passwords and speed selector.

In terms of its form factor, the ISD4002-120P comes in a 1.43” L x 1.11” W x 0.73” H plastic package, making it an ideal solution for quality voice recording and playback in limited form factor applications. It also includes a built-in potentiometer for adjusting to the desired position, allowing more control than what would be possible with an on/off switch.

With the combination of its form factor and features, the ISD4002-120P can be applied in a variety of applications including telephone messaging, industrial control and monitoring, alarm systems, automatic telephone answering systems, solid-state audio recording, sound track recording and monitoring, and interactive audio instructions. The versatility of this device goes even further by being able to record or playback commands or questions in a variety of languages, enabling use in multilingual environments.

The ISD4002-120P employs a variety of technologies in order to meet the requirements of its application field. To begin, it uses a Record Loop Technology (RLC) approach. The RLC works by creating what’s known as a “loop”, where each time a recording is triggered, a separate memory buffer is created for that recording. These memory buffers are fed in a continuous loop, with the cycle beginning and ending when the last buffer is used.

Moreover, the ISD4002-120P employs advanced technologies such as Voice Activation (VA) technology. This technology allows the ISD4002-120P to independently detect incoming signals and start recording only when specific voice commands have been detected. This is distinctly different from traditional recorders which must have incoming signals consistently present in order to continue operation.

Furthermore, the ISD4002-120P is equipped with three independent speed selection inputs to allow different speeds of playback. This helps provide the flexibility needed to support a wide range of applications, while also ensuring that all signals received are in sync to ensure the highest quality. Finally, the ISD4002-120P also has a built-in record password feature which allows an output signal to be tripped if the wrong password is entered.

The combination of the RLC, VA, and control technologies discussed above, makes the ISD4002-120P an effective and reliable device for use in a variety of interface-voice record and playback applications. With its compact size, high levels of playback speeds, record/playback capabilities and password protection feature, the ISD4002-120P is an ideal solution for interface-voice record and playback applications, many of which require reliable performance and superior sound.
