Page 6: Device Programming
Device Programming The DSP40plus programmable amplifier can be configured in two different ways: 1) using the display and navigation keys integrated into the control unit. 2) using the LEM USB application for Android smart phones, which can be downloaded free of charge from the Google Play Store. -
Page 7: Threshold Level
To speed up the programming process, you can use the AUTO-TUNING function. When this function is activated, the DSP40plus amplifier will automatically scan the inputs (1; 2; 3; 4) and store only DVB-T/T2 signals with a level equal to or higher than the THRES threshold (factory setting 55dBµV). -
