6 V olt ag e se lec tion The PLS-226 is factory-set (internally) for 100V, 120V, 200V, 220V, or 240V AC mains operation @ 50 or 60Hz. Make sure that the label on the bottom of the PLS-226 indicates the correct AC operating voltage for your location.

7 Se t-u p an d inst all at ion The N º 26 incorporates RCA-type and XLR-type connectors for audio signal input and output. The Madrigal-designed RCA-type connectors used for single-ended audio interconnection are a great improvement over ordinary RCA- type connectors. The gold-plated XLR-type connectors employed are of European design, and are ma[...]

8 The high-gain and low-gain phono options offer internally selectable cartridge loading via two four-pole miniature rocker switches, one for each channel. The high-gain and low-gain options have been factory- adjusted at 825 Ω and 47K Ω , respectively. If you wish to change the factory-adjusted cartridge loading, see "Making the internal [...]

9 If you wish to vary the input capacitance of the phono option to obtain the optimal value for a particular cartridge, a capacitor may also be inserted into the optional load terminals (see "Terminating the optional load" and "Making the internal adjustments"). Because the inherent input capacitance (all switches off) is in par[...]

12 Spec ific ations The correlation between published specifications and sonic quality is unreliable. A list of numbers reveals virtually nothing. All technical measurements must be subject to qualitative as well as quantitative interpretation. Measurements of the N º 26 yield excellent results by any standards. However, only those specifications [...]
