Updated at September 22nd, 2026

Learn how to use the Phones and C/RM outputs on the Soundcraft Signature Plus Series of mixers. In this video, we’ll explain how these outputs provide different ways to monitor signals at various stages of the mixer, whether you’re listening through headphones or sending audio to a control room speaker system.

You’ll learn how the headphone output can be used for checking signals, monitoring mixes, and troubleshooting audio, while the C/RM output can feed a monitor speaker, a pair of studio monitors, or a speaker system used by the engineer controlling the mixer.

Whether you’re mixing live sound, recording in a studio, setting up a podcast workflow, or checking signal before it reaches the main outputs, this video will help you understand how to use the Phones and C/RM outputs as practical monitoring tools.

 

Transcript
Hello, my name is Tony Smith and welcome back to the Soundcraft Signature Plus Video Manual Series. In this video, we’re going to talk more about the outputs of these mixers and cover the headphone and control room output controls.  
Below the mixer’s physical output connections are the controls for the headphone and control room outputs. A main level knob to control the signal level going out, as well as a mute toggle and an LED for monitoring the signal. DIM is available for a quick volume drop and SUM to sum the output signal to mono. 
The rest of the toggles are to select what signals are being fed to the respective output. You can receive any combination of the auxes, the listen bus, the main mix, the USB channels, and the talkback mic. This allows you the flexibility to have separate unique monitoring situations split between your headphones and a monitor speaker in the booth.
In the next video, we’re going to cover aux mixes, how to route them, and their available controls. Thanks for watching. For more news, product information, and troubleshooting tips, visit our Anytime Help Center at Help.Harmanpro.com
