7�3�2�2 Upsampling
You can choose interpolation filter type for upsampling slow (44�1 kHz - 192 kHz) PCM signals� Fast (352�8 kHz
- 768 kHz) signals are not upsampled� There are two realizations of interpolation filters:
HQ — made by HQ Player's creator, always upsamples signals to 352�8 kHz or 384 kHz� Processing is done in
SERCE�
ESS — built-in ESS Sabre32 DAC filters, upsamples signals 8 times� Processing is done in DAC chip�
We will add more filters in future releases�
● HQ Gauss
● HQ Apod�
● ESS Lin-Ph
● ESS Min-Ph
● ESS Apod�
7�3�2�3 Bypass
Bypasses volume regulator for all inputs to use it with external preamp� After activation converter will work at
full volume�
Please use the Bypass function with caution! A sudden jump in volume may damage your hearing and/or the
speakers!
It is best to reduce the input signal at the source to a minimum before the Bypass function is activated�
Note: Ferrum refuses every liability for damage to equipment due to using Bypass function.
7�3�2�4 Theater Bypass
Bypasses volume regulator for analog input only to use it with AVR source and its volume control�
7�3�2�5 Digital Input Trim
You can trim the level of all digital inputs up to -12 dB� It is realized on selected volume regulator (analogue or
digital)�
7�3�2�6 Analog Input Gain
Here you can trim or gain signal (+/-12 dB) of analogue input� It is realized on analogue volume regulator�
7�3�2�7 I2S In Format
You can choose frame format of the I2S input� Possible values are:
● STD 32 bits - standard I2S: word clock advanced by 1 bit and low level for left channel�
