Set this switch UP to select the 44.1kHz sampling rate. Use with an AES reference only. Ensure SW6 and SW8 are DOWN. The ADC-9532 will only provide a 44.1kHz sampled signal as long as it has a valid 44.1kHz AES reference signal. On loss of the 44.1kHz AES reference signal, the ADC-9532 will switch to internal reference at an undefined sampling rate. -
