I am trying to do the bypass. I have followed the instructions. Sound is passed to my Arcam AV40.
However, the volume control on the NAC202 has not been disabled (as described on the manual), meaning the bypass not working properly. Hence the two channels are not in sync with the rest of the remaining 3.1 in the case of 5.1
To select Unity Gain, first switch the preamplifier into program mode by pressing and holding the handset prog key (with the handset in preamplifier mode). The front panel source mute button (NAC 202 mute button) will illuminate if Unity Gain is selected. If it is not enabled it can be switched on by pressing the same mute button twice.
Unity Gain only becomes operational on exit from program mode by pressing and holding the handset prog key.
note: The preamplifier will leave program mode automatically if no control commands are receved for five minutes.
Yes I followed.
Whilst my NAC202 is in AV mode, I first press the “pre” button on the remote, followed by holding the “prog”. At which point my “mute” and “aux1” will come on with the LED on the volume control flashing. After I let go of the “prog” the selection reverts back to “av”.
To get out of “prog” I hold it again. This time the flashing LED on the volume control disappears.
Provided your source is up to it, I would recommend a HICAP or a NAC282 before the NAP250. The NAC202 and NAP250 can sound a bit unbalanced, a NAC282 and NAP200 is far preferable for similar outlay. A NAP250 really wants a NAC282 or above to work at its most effective.
With the HICAP the Flatcap is redundant. You could use it for something else though such as a Phono stage (Stageline) or Headphone amp (Headline), or to power the analogue output stage of a suitable Naim CD player (CD3.5/5/5x/5xs).
You could use the NAP200 for the AV centre channel speaker. Just use one of the channels, or if you were very creative with the DIN input you could even bi-amp, but be VERY careful of the powered 24V DC output on one of the DIN pins on the NAP200…
