C2200 Vacuum Tube Preamplifier Features
EIGHT PROGRAMMABLE SOURCE SELECTIONS
All eight source selections accommodate unbalanced inputs while four of the eight also accommodate balanced inputs. Any of 12 standard names can be assigned to a source selection and the panel display can be customized to indicate only available sources.
SILENT ELECTROMAGNETIC SWITCHING
Signal routing is accomplished through digitally controlled electromagnetic switching devices. 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.
