Cary Audio Design CAD 211 FE - Manual (Page 9)

INSTALLATION
Interconnect Cables
Signal input connection is made via the RCA input jack on the rear of the amplifier located next to the
output binding posts. The input interconnect cables from the output of the preamplifier can be any
length your installation requires. A shielded high quality interconnect cable is important to reduce
chances for hum or interference. Ask your Authorized Cary Audio Design audio dealer for advice.
WARNING!
 Page 10 shows correct tube placement positions, and 300B tube bias settings.
Page 11 shows 300B tube pin configuration. FAILURE TO INSTALL THE TUBES
CORRECTLY WILL DAMAGE THE UNIT. Watch the tube pins carefully on the
300B tube during installation as it is possible to force the tube to plug in
‘wrong’ during installation. The 300B tube has no ‘safety key’ center pin on the
tube to prevent incorrect installation. It has two large pins and two slightly
smaller pins. Please look carefully at the tube pins and the tube socket holes to
note the two different size connections prior to installation. Incorrectly
plugging in the 300B driver tube will possibly damage the amplifier and is not
covered by the manufacturer’s warranty.
