amplifier channels. The negative or “common” cable lead is always attached to the
“G” or “Com” center posts, while the “hot” or positive lead may be connected to the
4, 8, or 16 ohm posts (see “Matching Auricle To Your Loudspeakers” for more
information).
2b) For monophonic operation, set the Stereo/Mono switch to “Mono”. Use either input
jack, but not both. Use either set of output connectors, but not both.
3) Set the “GND” switch to “1” (the upper position). If you experience significant hum,
try the other position.
4) Set the “Triode/Ultralinear” switch to either position.
5) Connect the AC power cord to the IEC connector on Auricle’s rear panel. ALWAYS
connect power cord to component before plugging it into an AC outlet, and make
sure that unit’s power switch is set to the “off” position before making the final
connection. For best performance, try to route the power cord away from signal
cables.
6) Before turning Auricle’s power switch to the “on” position, your source component
should already be warmed up and the volume turned to zero.
7) Allow Auricle to warm up for a few minutes, then adjust output tube bias. (See
“Output Tube Bias Adjustment”, below)
8) Switch the Auricle off before turning off your source components; failure to do this
may result in damage to your loudspeakers, as the power amplifier will amplify any
‘turn off thump’ transients from the source components.
As with all high performance audio products, the sonic characteristics of all VAC products
will continue to improve during the first several hundred hours of use.
