Final answer:
The two common ways to send a signal to a multitrack recorder are through an analog signal and a digital signal. Analog signals are continuous and can be directly converted into digital signals for processing in recording devices. The two common ways to send a signal to a multitrack recorder are: Analog signal Digital signal
Step-by-step explanation:
The two common ways to send a signal to a multitrack recorder are through an analog signal and a digital signal.
An analog signal contains data that can vary continuously, such as the varying intensity values of sound or visual images. In the context of audio recording, this would be the direct electrical representation of the sound waves captured by the microphone. This analog signal is often converted into a digital signal for electronic processing in recording devices. The conversion process entails sampling the analog signal at discrete intervals and quantifying the intensity into binary code made up of ones and zeros (the digital representation).
While other methods like optical signal transmission and wireless signal transmission are also used for different applications, such as in wireless body microphones or data transmission for cell phones and television, they are not typically the main methods for connecting to multitrack recorders in a recording studio setting.
