Precision switch contacts, isolated from environmental contamination inside inert gas-filled glass tubes, provide the most reliable, quietest and lowest distortion switching possible.   VRV (VARIABLE RATE VOLUME) DIGITALLY CONTROLLED ATTENUATOR The output attenuator controls volume over 214 steps of .5dB each with accuracy within .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.   TUBE MANAGEMENT AUTO TURN-ON DELAY Outputs are muted until delay circuits sense the tubes are stabilized which prevents exposure to noise generated by other components.
