2 - Using the card : MONITOR ALIGNMENT option Setting the overall surround level This is set on the OPERATION screen after the channels have been aligned. For movie work, this is standardized at 85dBC, and for television at 82dBC1. Musical program material may use a higher reference level. 1 Turn down the level of the monitoring system. 2 Set the value of the desired reference level on the SPL REFERENCE field of the OPERATION screen. 3 Use POD 3 (or POD 1, as explained earlier) to set the level to the desired reference level. 4 Route the oscillator (pink noise) at nominal level through the surround system (all channels). 5 Adjust the amplification system so that the SPL meter located at the listening position reads 85dB. Now the POD 3 control can be used to reduce the monitoring level. Only increase the level if the material permits. • The monitor level can be set from 0dbC to 65dBC in 5dB steps, and from 65dBC to 109dBC in 1dB steps. • The SPL reference level can be set from 65dBC to 109dBC in 1dB steps. NOTE At SMPTE standards, there is 20 dB of headroom, so the SPL can be at 105dB before distortion occurs. 1. The term "dBC" refers to the "C" weighting average mentioned earlier. 16 TASCAM IF-SM/DM Owner's Manual
