Cary Audio Design CAI 1

The CAI 1 is a versatile audio processor that offers a range of features to enhance your listening experience. With its individual output levels for each input source, you can customize the volume for different devices without having to readjust every time you switch inputs. The CAI 1 also remembers the last volume level used for each input, so you can easily return to your preferred settings.

Another notable feature is the "Cinema Bypass" input, which allows you to connect your home theater system to the CAI 1 and bypass its internal circuitry. This ensures that the audio signal from your home theater system remains unprocessed, providing a pure and unadulterated listening experience.

Upgrading your CAI 1 to Firmware v1.2
The firmware v1.2 update allows the CAI 1 to have individual output levels for each input source. It
will also remember the last level setting used for that particular input.
For example:
You are listening to a CD through the CD input, and the display shows your volume level is set to
15. You then switch to AUX 1 input for another source and adjust the volume up to 25. When you
switch back to the CD input, the volume level will return to your previous setting of 15.
Also note:
When using the “Cinema Bypass” input, you must set the level to +46 to achieve unity gain. At +46
the output signal is at the same level as the input signal.
Flash Magic and CAI 1 software installation:
- Install the Flash Magic program on your computer.
- To enter the CAI 1 into software update mode you will need to first unplug the
power cord from the back of the unit. Leave the power cord plugged into
the wall outlet, simply remove the female end of the power cord from the power inlet on
the rear of the CAI 1.
-Once the power cord has been removed, while holding down the main power button on the front
panel of the unit, re-insert the power cord into the back of the unit.
-Once you have inserted the power cord, you may let go of the power button on the front panel.
The CAI 1 a is now ready to have the software updated.
- Connect the computer to the CAI 1 through the serial port on the back panel of the
unit. You may use a standard USB > serial cable to perform the software update. You will
simply need to ensure that the driver for the USB > serial cable has been installed on
your computer.
- The following are the settings for the Flash Magic program.
o Select appropriate COM port
o Set baud rate to: 4800
o Set device to: 89LPC932A1
o Set interface to: None (ISP)
o Oscillator Frequency (MHz) to: 16.0
o Select: “Erase blocks used by Hex File”
o Browse and choose the correct CAI 1 software Hex File, The name is CAI
1-V1.2-23-07-2008.hex.
o Do not select any options in step 4
o Press start
- The Flash Magic program will now begin erasing the older software version installed on
the CAI 1 and replace it with the new version.
- Once the status bar at the bottom of the program window displays “finished”, you will
again remove the power cord from the rear panel of the unit as well as remove the serial
cable from the serial port on the rear of the unit. Let the CAI 1 sit unplugged for 1
minute. Plug the power cord back into the rear of the unit and power the unit on.
To verify the update was applied, set the volume level on one input, then switch to another and set
it to a different level. Switching back to the first input, the level should return to the previous
setting.
