6—Using the S-4000 System
Monitoring Input Signals
Signal Status Indicators
The S-4000R has two rows of signal status indicators that allow you to monitor the signal activity on
the S-4000 System’s 40 audio inputs (1-32 for the S-4000S and 33-40 for the S-4000H).
• SIG—lights green when the input signal level is higher than -40 dB on a particular channel.
• CLIP—lights red when the input signal exceeds 0 dB. Once a CLIP indicator lights, it stays lit until
cleared with the CLIP CLEAR•ENTER button.
The signal status indicators represent the signal level in the digital domain (post-A/D conversion).
Signals exceeding 0 dB will clip, resulting in distortion.
Clearing the CLIP Indicators
When an input signal on a particular channel exceeds 0 dB, the corresponding signal status CLIP
indicator will light, and the CLIP CLEAR•ENTER button will flash.
To clear all lit CLIP indicators, press CLIP CLEAR•ENTER so its indicator goes out.
To keep a channel’s CLIP indicator from lighting again, lower the preamp gain on that particular
channel (see Page 67 for more information).
The signal status indicators also warn you when there’s a problem with the system. See Appendix
A: Troubleshooting for more information.
