Cary Audio Design CAD-805AE - Manual (Page 11)

OPERATION
POWER REQUIREMENTS
The CAD-805 Anniversary Edition is designed to operate from house current AC mains. The
design voltage is 117 Volts AC at 50/60Hz (Foreign units 234 Volts AC at 50/60Hz).
SPEAKER CABLES
The speaker cables from the output posts of the CAD-805 Anniversary Edition to the speaker
system can be any length that your setup requires. Select speaker cables of sufficient size to
preserve the outstanding performance capabilities and sound quality of your new power
amplifiers.
Heavy duty #14 gauge wire is suitable for distances up to 15 feet; #10 gauge is good for 25-30
feet. Most audio dealers have high performance speaker cable in stock for this purpose. We
strongly urge you to try several types to find the best ones for your combination of components
and speakers.
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 dealer for
advice.
Your new amplifier is ready for operation after the speaker cables, interconnect cables and the
tubes have been installed. Choose either the 211 or the 845 output tube with the top panel tube
selector switch, according to the actual one installed. Only change this switch setting with the
amplifier OFF.
WARNING
• 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.
Please see the DIAGRAMS section for further instructions on tube placements.
OFF/ON POWER TOGGLE SWITCH
Push the AC toggle switch toward the rear, to the “ON” position. The 6SN7 input tubes, 1629 Cat
Eye tube and the 300B driver tube will light up in this setting.
STANDBY TOGGLE SWITCH
Push the toggle switch toward the rear of the unit to operate. The output tube will light up.
