ABSTRACT:
In electronic amplifiers it is desirable to have the capability of accurate setting of the characteristic values while still having a limited space on a front panel. In order to accomplish this, a digital switch having a plurality of digital switch units on a front portion is coupled to an amplifier assembly. The amplifier assembly is coupled to the back portion of the digital switch and has a configuration such that it can fit into the same opening in the panel as the digital switch alone. Thus, the entire electronic amplifier unit takes up no more frontal space on the panel than that necessary for mounting the digital switch alone.
