3 OPERATION
3 . 1 I N P U T S O U R C E S
The ADL 600 can be used with a variety of input sources: microphones,
instruments and line level devices.
3 . 2 M I C R O P H O N E S
The ADL 600 works great with all types of microphones including dynamic,
ribbon and condenser microphones. Dynamic microphones and ribbon
microphones are generally lower output devices and require no external power
source. Condenser microphones are generally more sensitive than dynamic and
ribbon microphones and typically require external +48V phantom power.
Microphone Input Impedance
You can adjust the input impedance on the ADL 600 to match or "tune" a
particular microphone to achieve a desired sound. Most microphone
preamplifiers have a fixed microphone input impedance of 1000 to 2000 ohms.
The ADL 600 has four different impedance values to select from: 50, 150, 900
and 1500 ohms.
As the impedance on the ADL 600 is lowered, a resistive load is put on the
microphone. This will not damage a microphone. However lowering or raising the
impedance can create subtle coloring and filtering effects and can be a perfect
solution for a particular application.
3 . 3 I N S T R U M E N T S
You can connect a variety of instruments via the Hi-Z INSTRUMENT input on the
front panel of the ADL 600 including: acoustic and electric guitars, bass guitar as
well as older keyboards with Hi-Z instrument level output such as the Rhodes
keyboard.
3 . 4 L I N E I N P U T
Line input is included on the ADL 600 to be used as a preamp/signal conditioner
for line-level devices such as keyboards, drum machines and sound modules.
You can also use the line inputs for running your mix through the ADL 600 to give
it an extremely full, rich character.
