Hi yall!
I know FX are 24bits but the only thing I 've found is (from the manual) 1bit Sigma-Delta (?) Any 1 knows?

1bit Sigma Delta x64??? I'm bugging! is the ASR a 64bits sampler???

The machine is 16-bits on the input and output stages. 16-bit refers to the Signal-to-Noise Ratio (SNR) of the audio signal which is means that audio is accurate on a scale of aobut 0-to-65000 or 0-to-(2^16) levels (about 96dB above noise floor).
The actual bits sampled right at the input is only 1-bit accuracy but the rate of sampling in 44.1KHZ x 64 or about 2.8MHz. So technically the ASR is a 1-bit sampler, but it samples at 2.8MHz. At this high frequency and using special circuits to move the "noise" in the 1-bit signal to the bandwidth outside the audio range (i.e. above 20kHz), the 1-bit sample can be filtered/resampled to 16-bits and 44.1khz.
Nearly all samplers that a 16-bit or higher have these types of converters since they became popular as CD technology began commercialization. The Emulator III and Casio FZ-1/10/20 are some of the few 16-bitters that have ADCs as you'd expect with 16-bits of quantization at the nominal sampling rate or very close to it.
