Can the output of an ARC PH-7 be turned down?

does your Calypso have adjustable gain and is it set at the lowest level? There's an adjustable jumper inside the case. Aesthetix can tell you. Even the low gain was too high for my system so I got rid of it.

You can also try putting 5751's(gain factor 70) in the 12AX7(gain factor 100) sockets this will decrease the output level.

In the Calypso!!!

I would get Audio Research's take on it..

Hi Handymann,

Excellant purchase selections BTW. As already mentioned the only reduction of gain that I can offer you is through the Calypso. The adjustable shunts need to be on the 2 inside positions to reduce the gain by -12dB.

The non reduced gain is stated at 29 dB balanced and 23 dB single ended.

Lowering the gain by -12 dB reduction would still put you at 17dB for balanced and 11 dB for single ended.

I prefer the lower gain setting to the high setting. Tape hiss being noticable with the high setting is the reason given by Aesthetix for the adjustment of gain.

Using 5751 tubes will also decrease the output level as stated above.

I am using the Calypso single ended so I can not advise you on gain and overload using balanced connections.
