RCA Input Voltage Range

[idealamp]

Hi all,

Would someone be able to confirm the RCA input voltage range of the Stereo Sound card.
It is quoted as 3.3 V on the main page, i would like to confirm if this is

A) 3.3V peak to peak i.e. Swinging between +1.15V and -1.15V

B) 3.3V amplitude i.e Swinging between +3.3v and -3.3v

Confirmation would be highly appreciated as i would like to utilise the full dynamic range of the ADC.

Many thanks.
