NuTone SM428 stereo master station

The SM428 Stereo Master Station is rated at 6 watts per channel RMS.  The SM428 Master Station does not have any built-in speakers, it was designed to be installed with a pair of SS40 Deluxe In-Wall Speakers.

The SS40 speakers are rated at 8 ohms. The SM428 was designed to have up to 2 pairs of the SS40 speakers installed, however it would reduce the total number of standard speaker from 7 to 4

The SM428 has separate Volume, Bass, Treble and balance controls.  This Master Station is missing the knobs that fit over the dual fader controls.
