General Description
Instrument Features
The
Model 3300 Audio Monitor
is a high quality audio amplifier designed to transform
electrophysiological signals into sounds. This amplifier features a built-in 6-band audio
equalizer that enables the user to tailor the audio performance to their personal
satisfaction, a high-fidelity quality speaker, a dedicated notch filter designed to minimize
noise interference generated by power lines, a headphone jack, and an BNC line out jack
that enables the the Model 3300 to be used as another signal amplifier prior to
subsequent processing by other instruments.
The instrument can be placed on a lab bench with its built-in metal stand, or it can be
mounted in any industry standard equipment rack (with included rack-mounting hardware).
In addition, the instrument is shipped with it’s own desktop power supply.
It can be used in a number of research or teaching applications requiring the audio
reproduction of electrophysiological signals, such as such as nerve, muscle (EMG), EEG,
EKG, and ERG recordings.
The instrument is not intended for clinical measurements using humans.
Two input signals can be passed to the
Model 3300.
A toggle switch selects which of the
two signals will be amplified and processed by the 6-band equalizer. The Equalizer is a
tunable filter that can increase or decrease the gain of particular frequency ranges,
resulting in a pleasing sound quality produced at the speaker. The use of a set of
headphones (by utilizing the mini-headphone jack) will disable the internal audio speaker.
The volume control acts as a variable gain amplifier, and adjusts the volume of the
speaker output. The processed signal can be passed to an oscilloscope or other
instruments via the Signal Out BNC jack.

Operator’s Manual 1001 iii
EMC RELATED CAUTION
This equipment and/or system complies with the International Standard IEC 60601-2 for electromagnetic
compatibility for medical electrical equipment and/or system. However, an electromagnetic environment
that exceeds the limits or levels stipulated in IEC 60601-1-2, can cause harmful interference to the
equipment and/or system or cause the equipment and/or system to fail to perform its intended function
or degrade its intended performance. Therefore, during the operation of the equipment and/or system, if
there is any undesired deviation from its intended operational performance, you must avoid, identify and
resolve the adverse electromagnetic effect before continuing to use the equipment and/or system.
The following describes some common interference sources and remedial actions:
1. Strong electromagnetic interference from a nearby emitter source such as an authorized radio station
or cellular phone:
Install the equipment and/or system at another location. Keep the emitter source such as cellular
phone away from the equipment and/or system, or turn off the cellular phone.
2. Radio-frequency interference from other equipment through the AC power supply of the equipment
and/or system:
Identify the cause of this interference and if possible remove this interference source. If this is not
possible, use a different power supply.
3. Effect of direct or indirect electrostatic discharge:
Make sure all users and patients in contact with the equipment and/or system are free from direct or
indirect electrostatic energy before using it. A humid room can help lessen this problem.
4. Electromagnetic interference with any radio wave receiver such as radio or television:
If the equipment and/or system interferes with any radio wave receiver, locate the equipment and/or
system as far as possible from the radio wave receiver.
5. Interference of lightning:
When lightning occurs near the location where the equipment and/or system is installed, it may induce
an excessive voltage in the equipment and/or system. In such a case, use an uninterruptible power
supply.
6. Use with other equipment:
When the equipment and/or system is adjacent to or stacked with other equipment, the equipment and/
or system may affect the other equipment. Before use, check that the equipment and/or system
operates normally with the other equipment.
7. Use of unspecified accessory, transducer and/or cable:
When an unspecified accessory, transducer and/or cable is connected to this equipment and/or
system, it may cause increased electromagnetic emission or decreased electromagnetic immunity.
The specified configuration of this equipment and/or system complies with the electromagnetic
requirements with the specified configuration. Only use this equipment and/or system with the
specified configuration.
Caution - continued
iv Operator’s Manual 1001
8. Use of unspecified configuration:
When the equipment and/or system is used with the unspecified system configuration different than
the configuration of EMC testing, it may cause increased electromagnetic emission or decreased
electromagnetic immunity. Only use this equipment and/or system with the specified configuration.
9. Measurement with excessive sensitivity:
The equipment and/or system is designed to measure bioelectrical signals with a specified sensitivity.
If the equipment and/or system is used with excessive sensitivity, artifact may appear by
electromagnetic interference and this may cause mis-diagnosis. When unexpected artifact appears,
inspect the surrounding electromagnetic conditions and remove this artifact source.
If the above suggested remedial actions do not solve the problem, consult your distributor for additional
suggestions.

Introduction
Introduction
The electronic stimulator is used for the basic physiological and
pharmacological research and experiments.
This device is designed for experimental and research
applications and must not be used for therapeutic purposes.
WARNING
By simple operation of the panel, a single pulse, pair pulse, train pulse
and repeat pulse according to main interval can be output, as well as
various mixed waveforms in combination with an external signal, and a
biphasic pulse.
The stimulator is also equipped with a booster amplifier to allow field
stimulation.
Features
/Simple train stimulation
A single pulse, pair pulse or train pulse can easily be output.
/Built-in main interval function, independent of stimulation waveform
setup
Starting/Stopping and the repeat time and repeat count can be set separately
using the main interval function, ensuring simple, reliable operation.
/Field stimulation
The built-in booster amplifier with a maximum output of ±50 V and 400
mA enables direct field stimulation with any stimulation waveform.
/Simple biphasic pulse stimulation
/Mixing and modulation input terminals that allow output of mixed and
modulated waves through combination with an external signal
/Alternate stimulation by the addition of an evoked response to eliminate
stimulation artifacts
/Output of information to an external device such as a Power Lab
All set stimulation conditions and operating information can be output
from the USB port to an external device.
/High precision, high reliability design
By adopting a crystal oscillator as the internal base oscillation source and
combined with IC technology, time-related items can be controlled with
extreme precision, ensuring excellent reliability and reproducibility as well
as stable operation.
/Fine adjustment of output voltage
The output voltage setting can be adjusted up to 10 V.
/Input/Output protection circuit
The built-in protection circuit prevents damage in the event of an accidental
short circuit in the output terminal or synchronization signal output terminal
or excessive voltage (max. 50 V) to the input terminal.

External Trigger (EXT TRIG)
Like MAIN INTERVAL, this generates a trigger pulse. It is used to control
the stimulation repeat cycle by an external signal.
When EXT is selected with the trigger selector button, stimulation occurs
in synchronization with the signal that is input to the external trigger
terminal on the rear of the stimulator.

(EXT TRIG LEVEL)
Function
Selects whether the trigger is activated at the signal level that is input to the
external trigger terminal (on rear).
Adjustment range: 0 to ±10 V.
If the sweep-wave output from the oscilloscope is used as the external trigger
signal, the stimulation pulse can be monitored at any position on the oscilloscope
tube by setting the level adjustment knob.
Allowing for a noise margin and hysteresis in the built-in comparator, use a
trigger signal to oscillate up to about 1 V lower than the trigger level.
[Fig.11]
When set to SYNC
When the knob is turned fully counterclockwise until it locks (SYNC position),
the trigger level is approximately +3 V.
When activating the trigger at a pulse of +5 V, the inconvenience of setting
the level can by avoided by using this position.
