We felt that an “ultimate” attenuator for the BeePre needed to be done to a higher standard and we felt that it would be reasonable to make the kit similar in price to the other high end attenuators on the market. So we got very high quality rotary switches and PB put his math degree to work coming up with a very useful thirty-six 1.5dB steps, yielding a total -52.5db of attenuation. Yes, you read that right, 36 steps. We accomplish this with two six position switches, one a stereo coarse control with 9db steps and the other a stereo fine control with 1.5 db steps. Simply set the coarse control in the general range you want to listen and then use the fine control to get the level perfect. Now that high quality attenuator is available for the Stereomour II.

The switches are populated with Vishay Dale metal film resistors, a resistor that has remained a favorite of ours over the years for attentuator use. The TwoQuiet coarse and fine stereo switches replace the stock carbon pot volume and balance controls in the Stereomour II. They mount on a custom aluminum sub-chassis, and we provide a neat overlay for the top of the chassis, with attenuation settings, input selector setting and a cool vintage look. 

As always the kit comes with an extensive, detailed manual. Assembly and installation is probably a one or two evening affair.

Why install this upgrade?

When we put the protoype in our production prototype BeePre the bass punch and dynamics became like Wow! Can’t say for sure why, as both the stock pots and the BeeQuiet are about the same impedance at around 50K ohms. So this is another case where we won’t try to come up with some far fetched theory. We will just suggest strongly that you build the Crackatwoa with the stock volume and balance pots first, then install the TwoQuiet upgrade and share your impressions.
