hi, everyone,

i have a test about 1701, analog input,  after the L/R ADC input Resistance 18k, the signal, reduce to 1/2 RCA input level.

like RCA input 1.0V,  test the point after Resistance 18k, just have 0.5V, and the DAC output also have 0.5V,  but inside the DSP is do nothing, just passthrou.

 

when i put a Gain function inside the DSP, like +6dB, and then the DAC output have 1.0V, but have noise. i didn't have check if output is clip.

any ideas ?
