Tone/White Noise Generator (Requires speaker)
Product #: A69-20
|
This unit is a self-contained tone and white noise source with an integral power amplifier to drive a speaker. It has a universal 5 to 30 Volt control input so that it may be operated by Habitest Lincs, LabLinc V modules, or Tru Scan Lincs. You may manually select noise or one of 30 tone frequencies to be presented either manually or by program control. It is also useful for general masking applications in room-sized areas. It is powered by a wall-mount supply (provided). Tone frequency is set by selecting one of 15 frequencies on the rotary selector switch. A range switch allows you to select either one or ten times the set frequency. The 16th position on the switch is the white noise selection.
Available frequencies range above human hearing to 30KHz for use with rodents. At the upper end of the available spectrum you must use a high quality tweeter to deliver the stimulus.
The unit may be manually operated momentarily by pressing the stimulus gating switch down, or indefinitely by placing it in the up position. When the switch is in the center position, the unit is gated on by a signal to the universal control input on the back of the case. The unit is powered by a wall-mount power supply which is supplied with it.
