Figure 2.1 The Front Panel
Physical Description
The logger is housed in a 1U high 19” rack mount box.
The front panel is sprayed with a green to purple “flip”
colour, which also has a fish-scale overlay. There are
chrome plated panel inserts for the fan inlet/outlet with
domed labels for the “Sonifex” and “Net-Log”.
Power
The unit is powered via an IEC filtered input for 95 – 265V
supply at 47–63Hz, peak 60W, 30W average. There is an
external fuse for the mains input that is rated at 2A. We
recommend that the Net-Log is operated from an
uninterruptable power supply. It should be noted that the
record header is written regularly during the record
process so if the power fails the data lost will be limited.
At a bit rate of 192kbps this loss will be a maximum of 1
minute. Lower data rates will give proportionately greater
time loss.
Level Indicators
There are four tri-colour LED’s positioned on the front
panel indicating input levels for each individual channel:
Led State
Meaning
Off
Input level < -18dBu
Yellow
–18dBu < Input level < 0dBu
Green
0dBu < Input level < 12dBu
Red
Input level >12dBu
Record Control/Indicator
This backlit button gives an indication of what channels
are currently being recorded and can also be used to give
limited control over the recording. When pressed, the
button will flash indicating that a record start or stop has
been initiated and must be pressed again within three
seconds to confirm the action. The LED states and their
relative modes are shown below:-
Button State
Mode

No channels recording

On
All available channels recording
When the button is pressed, the Net-Log checks to see
which channels can be altered using this button (See
Options, Record Format options, Override Enabled). If
recording, a confirmed button press will stop the
recording. If not recording, a confirmed button press will
start the recording on enabled channels.
