Inverted Double-Chassis Design

All analog signals and amplification are nestled into the top section, protected from any noise generated by the power supply or digital circuits that are contained in the bottom section. This achieves the performance of a dual-box component with the convenience of a single-chassis component and provides for ultra-short cabling between sections.

Silent Electromagnetic Switching

Signal routing is accomplished through digital controlled electromagnetic switching devices. Precision switch contact, isolated from environmental contamination inside inert gas-filled tubes, provide the most reliable quietest and lowest distortion switching possible.

VRV (Variable Rate Volume) Digital Controlled Attenuator

The output attenuator controls volume over 214 steps of 0.5dB each with accuracy within 0.1dB. The volume vs. rotation rate varies as preamplifier gain varies and attenuation changes occur at the zero crossings of the audio signal to prevent audible artifacts during adjustment.
