The Io may optionally be configured with volume controls and a line-level input, suitable for a CD player or other line-level source. 

The volume controls are dual mono and identical to those in the Callisto. Each volume control consists of four silver contact Shallco 46 position switches ganged together in a unique configuration. Each switch consists of 46 Roederstein resistors for a total of 184 Roederstein resistors per channel! All other volume controls sound different at lower levels than they do at higher levels, due to non-linear elements or the number of solder connections and resistors the signal must traverse. Aesthetix unique configuration means that the sound quality is the same at lower levels as at high levels. 

With the option of volume controls comes a high level input. This input is balanced or single-ended, with both XLR and RCA jacks provided. A single-ended input will be balanced by the Io. 

Any Io, of any version or age, may have volume controls added as a factory upgrade.
