The front panel of a Dual Bio Amp has a single input, two indicator lights and an audio
output connector.
The front panel of the Quad Bio Amp has nine single-ended 1.5mm sockets consisting of
four red connectors, four black connectors and a single green connector.
The front panel of the Octal Bio Amp has seventeen single-ended 1.5 mm sockets
consisting of eight red connectors, eight black connectors and a single green connector.
The Input Socket
Connections are made to the Bio Amp are made using the three shrouded 1.5 mm male
pin sockets on the front panel. A separate socket is provided for each of the positive (+),
negative (–) and Ground/Reference (Ref) cables.
Connections are made to the Dual Bio Amp using the six-pin socket on the front panel.
The socket is physically and electrically isolated from the low-voltage mains-supply
circuitry of the PowerLab, and the input connections are isolated internally, by isolation
circuitry. The socket is of a sort commonly used with ECG-type cables and leads, such as
the Bio Amp cable and leads with which your Bio Amp is supplied (Tronomed D-1340 or
Tronomed D-1540).
Connections are made to the Quad/Octal Bio Amp using individual lead wires (supplied
with every unit) and a common ground, rather than using a single multi-pin socket. Each
of the Bio Amp inputs has one red and one black connector and an indicator light. The
green connector is a shared ground connection across all eight inputs in Octal and four
in Quad.
The Status Indicator
The status indicator light of a Single or Dual Bio Amp is located at the bottom left of the
front panel. The status indicator lights of an Octal and Quad Bio Amp are located above
the pair of red and black connectors of each input on the front panel.
When an ADInstruments application such as LabChart starts, the status indicators
should flash briefly and then remain green, indicating that the program has found the
front-end, checked and selected it, and is ready to use it. If a status indicator does not
turn on and stay on when the application starts, it is most likely that the front-end is not
connected properly.
The Back Panel
The back panel of the Bio Amp provides all the sockets required to connect the front-
end to the PowerLab and to other front-ends.
Audio Out Socket
Bio Amps have audio monitor outputs on the rear panel that can be used with standard
headphones or externally powered speakers. The 3.5mm headphone socket provides
sound output from a soft ware-selected data channel. The audio output may be of use
when monitoring nerve firings to control the placement of electrodes, for instance.
