12V Power
The instrument input can be used to amplify an electret
capacitor microphone. These are common for applications
where a small microphone is mounted inside acoustic
instruments, or lavalier style microphone used somewhere on
the outside of the instrument. Normally these microphones will
contain very small integrated preamps which require a voltage
to power. So the ALiX can send 12V phantom power out on this
input. This is activated via DIP switch # 3 on the side panel.
12V power can be applied to the tip or ring of the instrument
input jack. Conguration is done via internal jumpers,
described in detail on pages 12 & 13.
NOTE: this power supply charges up slowly, so you may need
to wait a few seconds before signal from your electret mic is
present at the input of ALiX. It is always best to make your input
connections before applying power at the DIP switch, and power
OFF the 12V at the DIP switch before disconnecting your source.
