Connecting Your Micro Stack

Hooking up your new Micro Stack (or just one of them) is a quick and easy process. Your source will need an analog line out, or if you are using the Micro DAC, a digital output which could be USB, coaxial, or optical. You will need a mini-mini cable to hook up your Micro Amp and DAC. Shown here is a 6” Cardas mini-mini cable, available for purchase on our website.

Changing Batteries

The Micro Amp and DAC run on DC power or two 9 volt batteries. The battery life of your Micro Amp will last approximately 15-20 hours, depending on the impedance level of the headphones you are using, as well as the electronics module you have (The DAC will not last quite as long). Most people have the Micro Module, which allows for about 15-20 hours of battery life. If you have the Desktop Module, then you should typically get around 8-10 hours of bat-

2.Connect your digital source to the DAC by plug- ging in a coaxial or optical cable into the optical/co- axial digital input or a USB cable from your computer into the USB input.

Some rechargeable batteries are slightly longer than a standard 9 volt battery. If you are using a longer 9 volt battery, slide them in allowing for the rubber flap to fold up into the top of the enclosure, shown lower left. The Micro Amp does not recharge your rechargable batteries.
