I am a bit confused.
I am using the JDS Labs ODAC and O2 (which has standard 2.5x & 6.5 X gain) as two seperates.
I always use the 2.5x gain with my Beyerdynamics DT 880 (250 Ohm).
(I never use the 6.5x gain because the sound is muddy and somewhat distorted.)
Well, the ODAC has about 2 V RMS output (and is connected via the USB cable to my laptop).
So the O2 will clip but not too much? There was a whole discussion about clipping in the ODAC/O2 thread.
It was suggested that to reduce clipping one should reduce the computer's volume level to, say, 50%. ...
...or to clip some resistors or capacitators or something else in the O2 amplifier. -
I am not a DIY'er or an engineer, so I don't know that at all.
On the other hand the instructions from the JDS Labs say that one should max the volume on the computer to 100%...
but max volume causes clipping.
your confusing two things:
1. "clipping" resistors: in order to change the gain settings of the (standard) O2, you need to open it up and cut out one of the resistors. depending on which you cut out, your gain settings will be changed to either x1 and x2.5, or x1 and x6. ive done it myself.
2."clipping" is also a term for when an amp reaches its limits:
Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping may cause it to output power in excess of its published ratings.
btw, i own dt770s, also 250 ohm. and on x2.5 gain i do believe youll deafen yourself before you reach into clipping... its more likely to occur as a result of improper eqing i think. but i may be wrong there.
