12.2 Audio output
This is a standard 2,5mm STEREO phone jack that can
be connected to any device which offers an audio input.
Depending on model and manufacturer, these are labeled
differently: e.g. PHONO, CD, LINE IN, MIC etc. Depen-
ding on the kind of input, you need a fitting adapter cable,
which you can purchase from any third party dealer.
NOTE: The internal speaker will not be disabled if you
use the audio output.
12.3 Jog Dial / Volume control
The Jog Dial, like on modern cell phones or PDAs, repla-
ces the up/down arrowkeys (“turn” the jog dial) and the
Enter key (briefly “press” the jog dial). Like this, you can
e.g. control the complete menu system just with this prac-
tical little wheel.
However, with the demodulator activated, this jog dial
serves as a volume control. As a precaution, before
connecting anything to the audio output, you should turn
this volume control all the way down to zero to avoid over-
load.
12.4 USB connector
The 5-pin mini USB B connector on the SPECTRAN allo-
ws fast communication with a computer or notebook. With
this feature, you can e.g. download data from SPEC-
TRAN’s data logger, perform software (firmware) updates
or perform advanced signal analysis using your PC with
our SPECTRAN PC software.
For this connection, you need a high-grade, shielded
USB 2.0 cable with USB A to Mini USB B 5-pin (see Aaro-
nia accessory list).
