1 About this manual
This manual, which is intended for the user of the QuickAmp, contains general operating instructions, precautionary
measures, maintenance instructions and information about components. To maximize the safety, service life and
efficiency of the system, it is important that you read this manual through carefully and familiarize yourself with the
various controls and accessories before starting to use the system.
2 Product description / intended use
The QuickAmp 136 is a 136-channel stationary system for physiological research.
The system has 128 unipolar electrophysiological (‘ExG’) inputs, 4 bipolar electrophysiological (‘BIP’) inputs, 4 so
called auxiliary (‘AUX’) inputs and one digital input-channel (8 bits).
The unipolar electrophysiological inputs are configured as a reference amplifier: all channels are amplified against
the average of all connected inputs. With these channels or the Bipolar channels signals like EEG, EMG, ECG,
EOG, EGG etc. can be measured.
The auxiliary inputs can be used for measuring temperature, pH, respiration, oxygen saturation etc. Each AUX
channel has a +5V and –5V output in order to use active sensors or sensor modules.
An external power s upply, which plugs into the mains socket, powers the Q uickAmp. The QuickAmp is connected to
a PC by means of bidirectional glass fiber. Inside the PC a special interface board (DSP/fiber card) or a USB
interface takes care of the glass fiber communication. The QuickAmp is in this situation completely controlled by the
PC.
The system does not perform any signal interpretation or signal analysis. This is left to the researcher/Physician.
The system is NOT intended for use in a life supporting system.
indications for use
The QuickAmp Amplifier family is intended to be used by or under the direction of a p hysician for acquisition of
EEG, polygra phy and polysomnography signals and transmission of the signals to a PC d uring recording of neurophysical/ physiological research and exams.
Polygraphy and Polysomnography may besides EEG, include physiological information such as EMG, ECG, EOG,
EGG, PH, Respiration, Temperature and Oxygen Saturation.

4 Installation
Install the fiber interface (Fusbi) by placing the hardware and use the drivers software as supplied on the separate
CD.
Find a well grounded mains socket for the external power supply, and connect the power connector to the back of
the QuickAmp.
Connect the bidirectional fiber to both the installed interface card and the back of the QuickAmp. A good
connection is indicated by a little ‘click’.
Turn the QuickAmp on with the switch on the back. The POWER ind ication should li ght up. When this is the first
time on the PC the PC will ask for the driver software which can be found on the same CD as needed for the fiber
interface. The front-end is now ready for use.

QuickAmp Manual
Using Subject electrode leads
For unipolar (‘reference amplifier’) signals: use 2 or more unipolar shielded cables with snap connector or fixed
Ag/AgCl electrode cup (micro-coax inputs).
For bipolar signals: use 1 or more bipolar cables (4-pin bipolar inputs).
The numbers placed near the connector correspond to the QuickAmp output channels.
For a good measuring, make sure the electrodes make a good contact with the subject. Ag/AgCl electrodes are
recommended, because of their excellent signal quality and stability.
Subject ground
Always use one unipolar shielded cable (snap connector or fixed Ag/AgCl electrode cup) for subject ground (GND
connection).
It is very important, that the impedance of the subject ground is kept low, if possible below 5kOhm. To guarantee
that the impedance of the subject ground has low impedance several measures can be taken, like cleaning the skin or
adding a lot of gel. We recommend a special electrode, the wrist belt electrode. This electrode is shown in the figure
below. The electrode is saturated with water, and fastened on the wrist.
Using Auxiliary sensors
Connect the auxiliary sensor (e.g. 3D-accelerometer) to one (or more, if required) of the 5-pin auxiliary inputs. The
numbers placed near the connector correspond to the QuickAmp output channels.

In the QuickAmp-system the following items can be identified:
Subject Ground connector
electrophysiological (ExG) and (BIP) input connectors
headcap connectors
auxiliary (AUX) input connectors
ExG impedance measurement
ExG calibration
digital input
external power supply connection
bi-directional glass fiber
Subject Ground connector
The Subject Ground electrode is meant as a way to keep subject potential and QuickAmp amplifier potential at about
the same level. It is not an active input. For good disturbance-free measurements make sure that the subject ground
electrode has low impedance.
Electrophysiological (ExG) and (BIP) input connector s
The ExG input s on the front of the Qui ckAmp are used to perform ExG (EEG, ECG, EOG, etc) measurements. All
electrode cables are individual shielded (active shield). This ensures a disturbance free measurement. 50 Hz mains
interference and cable movement artefacts are reduced to a minimum.
Inputs that are not connected to an electrode cable are automatically switched off.
It is advisable to use only one type of electrodes (e.g. Ag/AgCl, Sintered chloride, Gold, tin) at a time, including the
subject ground electrode. Different metals will cause large electrode offset differences, which might overflow the
amplifiers.
Headcap connectors
The headcap connectors (situated at the back side of the box) are another way to connect the subject to the front-end.
The inputs are connected directly to the accompanying unipolar ExG input. The active shielding signals are not
present on the headcap connectors. Appendix 3 shows the list of pin numbers of the connectors.
Auxiliary (AUX) input connectors
The auxiliary inputs can be used to connect active sensors like SaO2 sensors, 3D-accelerometer, respiration bands,
nasal flow sensors, pH sensor s etc.
Each auxiliary input has a 5-pin connec t or. Signals on this connector are +5V output, -5V output, GND, +signal
input and -signal input.
An unconnected input will automatically be switched off (i.e. will show a zero signal).
In Appendix 3 the pin-out of the AUX connector is given.
ExG impedance measurement
The QuickAmp contains a circuit to perform ExG electrode impedance measurements.
The impedance measurement can be started with the PC. The PC-controlled impedance measurement starts by
sending the front-end an impedance measurement command and an impedance threshold value. Like in the manual
mode, all channels that have an impedance higher than the threshold value will have their LEDs turned on.
At power-up of the QuickAmp system all LED’s will be turned on for about 1 second.

QuickAmp Manual
ExG calibration
The PC can put the front-end in calibration mode in order to test the ExG amplifiers. This mode is indicated by a
blinking impedance LED. Select the calibration mode only if no subject is connected to the input. Otherwise the
subjects EEG will interfere with the calibration signals.
Digital input
On the backside of the system a DB25 connector and a BNC connector are available to be used as a digital input (8
bits DB25 and 1 bit BNC). On this input one c an connect e.g. the sync-output of a stimulator in order to trigger on
certain events. The inputs are electrically isolated from the rest of the system by means of optocouplers.
External power supply
To get the best signal quality (minimum 50 Hz interference) make sure that a well grounded mains outlet is used.
The external power supply guarantees patient safety during all circumstances. Do NEVER use a power supply other
than the one that came with the front-end.
A switch on the back of t he External power supply turns the system on or off.
Bi-directional glass fiber
The glass fiber interface takes care of the bi-directional communication between Quic kAmp a nd PC. Through this
link the PC can set the sample frequency of the QuickAmp, control the measurement mode (normal, impedance,
calibration) etc. The signal data from the ADCs is sent from the QuickAmp to the PC over the fiber in high speed
and at high resolution.
