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-1608/S-0816 System’s 24 audio inputs (1–16 for the S-1608 and 17–24 for the S-0816).
fig.6-37.eps
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.
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 51 for more information).
LED Input Meter
The S-4000R features an eight-segment LED input meter for precise input
signal measurement.
To view an input channel’s signal level with the LED input meter, turn the
[CHANNEL] knob to select the desired channel (1–16 for the S-1608 and
17–24 for the S-0816).
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.
The signal status indicators also warn you when there’s a problem with the system. See
Appendix A:
Troubleshooting
for more information.
The LED input meter represents the signal level in the digital domain (post-A/D conversion). CLIP will
light when the signal exceeds 0 dB.
