Figure 61 Gain Trim and Volume Controls Q Mic Line input gain 2 Pre mixer gain 3 Mix point gain 4 Post mixer trim 6 Output volume About Setting Gain Structure There are two approaches the system designer can take in setting up gain structure depending upon where output volume will be controlled The output volume of the DMP 128 may be controlled by either of the following two gain blocks e Volume and e Pre mixer gain In the following instructions setup is described for output volume or pre mixer gain when appropriate DMP 128 Software Control 102 Setting Input Gain Floating point DSP technology is internally more flexible than fixed point However the input ADCs and output DACs always run as fixed point so it is important to optimize the audio by setting the input level as close to 0 dBFS as possible This will maintain the resolution at 24 bit Within the DSP it is not critical to maintain audio levels at O dBFS in order to secure the resolution at 24 bit Input gain can be set using the intended input source device and typical source material When source material is not available it can be set using pink noise obtained either from a pre recorded track on a DVD or CD or a signal generator For program material set the input level so the meters reach approximately 15 to 12 dBFS with peaks at approximately 5 to 3 dBFS This setting provides enough headroom to accommodate transie
