Knob clearance in front of the mounting panel is ¾ (1.9 cm) WEIGHT 29.5 lbs (13.41 kg) net 44.9 lbs. (20.41 kg) in shipping carton EIGHT PROGRAMMABLE SOURCE SELECTIONS All eight source elections accommodate unbalanced inputs while four of the either 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 electromagnet 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) DIGIALLY 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 eh zero crossings of the audio signal to prevent audible artifacts during adjustment.
