Physical Connections 2.3
2.3 Physical Connections
Instrument Inputs: The ¼” TS connectors on the front panel are for use with a passive
instrument (guitar, bass, etc.). To use this input, turn the Source Select switch to the
“Inst” position on the desired channel.
Power User Tip: Passive instruments do not have an internal preamp and should
be plugged into an instrument input. Active instruments have an internal preamp
and a line-level output and should be plugged into a line input. Plugging a line-level
source into the instrument input on the front of the ADL 600 risks damage to the circuit
and is likely to produce a very loud and distorted audio signal. So don’t do that!
Mic Inputs: The ADL 600 mic preamps work great with all types of microphones
including dynamic, ribbon, and condenser microphones. To use this input, turn the
Source Select switch to the any of the mic-impedance positions on the desired
channel.
Power User Tip: Dynamic microphones and ribbon microphones (which are a special
type of dynamic mic) are generally lower-output devices that, with few exceptions,
require no external power source. Sending phantom power to a ribbon mic that
doesn’t require it can cause severe damage to the mic – usually beyond repair.
Condenser microphones are generally more sensitive than dynamic and ribbon
microphones and typically require external +48V phantom power. Always review your
microphone’s documentation and follow its recommended operating practices.
Line Inputs: These balanced XLR connections can accept signals from line-level
devices such as keyboards, drum machines, and sound modules. You can also use the
line inputs to give a stereo mix an extremely full, rich character. To use this input, turn
the Source Select switch to the Line position on the desired channel.
Outputs: The ADL 600’s output jacks employ a balanced XLR connector.
Power User Tip: All input and output connectors are transformer-
balanced XLRs with the following wiring standard:
Pin 1: GND
Pin 2: High (+)
Pin 3: Low (-)
IEC Power Connection: The ADL 600 accepts a standard IEC cord.
Note: The input power voltage is set at the factory to correspond with the country to
which the ADL 600 was shipped.
