freePORT PAS 400 Version 060328 13
2 Operation
Note!
To prevent audible clicks or thumps, turn the VOLUME control (11) or (14) for INPUT 1 or
2 all the way down before:
y connecting or disconnecting microphones or signal sources
y changing the input level sensitivity with the selector switch (10) or (13).
2.1 Dynamic Microphones - Distant-Miking Set-up
If the distance from the person speaking into the mic is 8 to 20 inches (e.g. when speaking
at a conference table, or making a speech from a podium), turn down VOLUME 2, connect the
mic to INPUT 2 and select the MIC (-65 dBu) sensitivity. Then adjust VOLUME 2 to the desired
level.
2.2 Dynamic Microphones - Close-Miking Set-up
If the mic will be used at close distances, i.e., less than 4 inches (e.g. singing, speaking close
to the mic because of high background noise), turn down VOLUME 1, connect the mic to
INPUT 1 and select the MIC (-45 dBu) sensitivity. Then adjust VOLUME 1 to the desired level.
Note!
INPUT 1 has phantom power (in the MIC and AUX positions) for powering condenser mics.
2.3 Electret-Condenser Microphones - Distant-Miking Set-up
If the distance from the person speaking into the mic is 8 to 20 inches (e.g. when speaking
at a conference table, or making a speech from a podium), turn down VOLUME 1, connect the
mic to INPUT 1 and select the MIC (-45 dBu) sensitivity. Then adjust VOLUME 1 to the desired
level.
2.4 Electret-Condenser Microphones - Close-Miking Set-up
If the mic will be used at close distances, i.e., less than 4 inches (e.g. singing, speaking close
to the mic because of high background noise), turn down the VOLUME (1 or 2), connect the
mic to the INPUT (1 or 2) and select the AUX (-25 dBu) sensitivity. Then adjust the VOLUME
(1 or 2) to the desired level.
2.5 Mixing Console or Line-Level Inputs
Line level inputs can be connected to INPUT 1 (electrically balanced with 0 dBu sensitivity) or
INPUT 2 (transformer balanced with +6 dBu sensitivity). These inputs have the same audio
quality, but INPUT 2 may be more immune to hum or noise because it is transformer balanced
and completely isolated form the mains ground.
2.6 Recording from the PAS 400
An analog recorder (e.g. Mini Disc, cassette, etc.) can be connected to the REC OUT outputs
and a 2-channel mono recording of all inputs connected to the PAS 400 can be made. If the
outputs of the recorder are also connected to INPUT 3 (e.g. for playback), then turn down
VOLUME 3 before making any connections. Turn the volume level up slowly to prevent
feedback (many recorders produce an output signal, for monitoring, while they are recording
