CAD 1543 MKII DAC
Thank you for purchasing the 1543 MKII DAC and we hope you will enjoy it!
1) Power, inputs and outputs
The CAD 1543 MKII DAC has no mains power switch and the DAC is powered on when the mains
power plug is connected.
The internal power supplies take time to sound their best. In our opinion there is a significant
change in sound quality after the first two-three hours after being powered on and then again
after 24 hours.
For this reason, the CAD 1543 MKII DAC is designed to be left plugged in at all times, and it will
run warm. We recommend that if you are leaving for an extended holiday, or if an electrical
storm occurs, you should unplug the unit from the mains supply.
The CAD 1543 MKII DAC has power conditioning circuitry built in. We recommend plugging the
DAC directly into the wall outlet to start with. We do not recommend using an extension lead,
outlet strip or most power conditioning products. In our opinion many power conditioning
devices will reduce the sound quality of the 1543 MKII DAC. If you do try a power conditioning,
please product pay attention to the flow, rhythm and dynamics of the music.
All audio components improve with time but the CAD 1543 MKII DAC is exceptional in this
regard.
You will find a noticeable improvement over the first 200 hours and continued improvement
during the first few weeks of use.
There is one USB input, one pair of RCA phono outputs and no switches.
There is a single 4mm banana socket on the rear panel that attaches directly to the signal
ground on the printed circuit board that contains the DAC integrated circuits. This connection
is for attaching a CAD Ground Control.
2) CAD 1543 MKII DAC and Computer Set-up
The CAD 1543 MKII DAC is "Plug & Play" when used with the CAD Audio Transport (CAT). Most
Linux based servers (which is almost all servers on the market) already have the CAD driver
installed and are typically "Plug & Play".
Melco, Innuos, Aurender, Auralic, SOtM, iFi and Fidata audio servers/streamers have all been
tested by CAD and are "Plug & Play" with the 1543 MKII DAC.
The CAD 1543 MKII DAC requires a driver to be installed on an y Windows computer before it
can be used. Apple OSX is not supported after Yosemite.
Please install the driver before connecting the 1543 DAC to your computer.
