What is a Rec Out?
A Rec Out, or Recording Output, is a feature commonly found on audio and video receivers or mixers. It allows users to send audio or video signals to an external recording device, such as a tape recorder, computer, or external mixer, without altering the original output being sent to the main speakers. This enables users to capture performances or broadcasts for later playback or editing.
The Rec Out usually provides a fixed-level signal, meaning it does not adjust based on the volume level of the main outputs. This can be particularly useful for recording purposes, as it ensures that the recording level remains consistent regardless of any changes in the volume settings on the receiver. However, users should note that the recording device must be compatible with the type of signal being outputted, whether it is analog or digital.
What is a Pre Out?
A Pre Out, or Pre-Amplifier Output, is another feature found on audio receivers that allows the user to send a signal to an external amplifier or powered speakers. Unlike the Rec Out, the Pre Out is designed to deliver a variable signal that can be adjusted via the main volume control on the receiver. This means that when you change the volume on your receiver, the output level to your external amplifier or speakers will change accordingly.
Pre Out connections are particularly beneficial for audiophiles who want to enhance their audio system with high-quality external amplification.
