Chapter 4: System-Parameters 20
4.3.2 Calculations
Some bits of SYSMETERL and SYSMETERR are reserved, so you should AND with 0x03ff before
processing.
The meter-reply contains the actual meter position in 1/8 dB steps. A value of 0 means peak, while a
value of 1 means -1/8 dB and so forth. If you wish to produce a meter that shows the amplitude in
whole dB steps, simply divide the number by 8.
The DSP-clip flag is found in bit 13, which can be accessed by ANDing with 0x2000. This flag has a
built-in timeout, so all you need to do is print it. The M5000 front-panel VU-meters use the 0dB
LED to signal DSP-clipping, but this information should be printed separately wherever possible.
4.4 Hardware-Specific Parameter Ranges
Some parameters have ranges that depend on the physical DSP-card configuration.
