Class A operation in a simple topology in order to deliver the most natural sound possible. The design of the X-2 has been kept simple and functional. An input selector switch selects between the four available inputs. The first input can be either balanced or single ended, and the other three inputs are single-ended.

The preamplifier has four sets of input connections, two sets of output connections, an input selector, tape selector, and one level control. It also has an AC line power connection. The preamplifier's voltage rating is indicated on the rear. It will be either 240 volts, 120 volts, or 100 volts. A .5 amp 3AG slow blow fuse is provided with 100-120 volt units, and a .25 amp slow blow fuse is provided with 220-240 volt units.

Mosfets provide the widest bandwidth of solid state power devices, however they were not chosen for this reason. The design of the X-2 does not seek to maximize the preamplifier bandwidth as such. The capacitances of the Mosfets provide a...

60 dB range of level with about .1 dB tracking. Most of the steps are in about 2 dB increments, with greater increments near the counter-clockwise position. The internal power supply for the X-2 consists of a two toroidal power transformers delivering an unregulated 160 volts which is actively regulated for each channel before feeding passive filtering.
