Connecting Your Micro Stack
1. Plug the mini-to-mini cable into the
line input of the Amp and line output
of the DAC. Don’t forget to select the
appropriate power source on each
unit.
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.
4. Plug your headphones into
the 1/8 jack on the front of the
Micro Amp. Adjust the volume
on the HeadRoom amp.
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-
tery life.
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.
To remove your 9 volt batteries, you
need to remove the rear panel. Un-
screw the thumb screws, and the
panel will fall away from the enclo-
sure. You can also gently grasp the
panel by the center cut-out for the
power supply and pull the panel off
the unit, shown below.
3. If you are only using the
Micro Amp, then connect the
source to the amp using the
(preferably) line out or head-
phone jack of your player to the
the line input.
When using standard alkaline batteries, or standard size rechargeable bat-
tereies, pull up the small rubber flap and slide the 9 volt battery in. The bat-
tery will slide completely into the enclosure and the rubber flap will hang
down in front of it, shown upper right.
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.
