Rz6 Signal Processor - TDT Medusa4Z User Manual

For Open Field experiments, place the speaker 10 cm from the subject. Be sure to position it to
the side of the subject, in line with the ear, NOT in front of the subject.
For more information on the MF1 speakers and full system specs, see the
Closed Field Setup
Each MF1 comes with a tapered tip for Closed Field experiments. The tip mates with the
provided ⅛" outside diameter (O.D.) PVC tubing (10 cm included). The MF1 comes with an
inline filter (pictured at left) that connects between the RCA cable and speaker input. This filter
should always be in place when using the MF1 speakers in closed-field mode. In closed-field
mode, the MF1 has undesirably high low frequency output. This filter reduces the speaker
output at low frequencies so that the output range can be equalized. When using the tube tip,
use the MF1's inline filter and the shortest tube possible. You can cut the 10 cm tube to the
desired length. A 3 - 5 cm tube length is typical. The tube should slide snugly into the tube tip.
You can push firmly without fear of damaging the tube. If you have trouble inserting the tube, a
small amount of silicon spray can be used. It may be easiest to spray silicone lightly on a cloth
first then put the tip of the tube on the cloth to apply it.
Warning
Other lubricants (WD-40, grease sprays, or similar) should not be used as they can damage the O-rings
surrounding the tube tip, or the tubes themselves.

RZ6 Signal Processor

The RZ6-A-P1 Multi I/O Processor provides the processing power for averaging signal inputs
and the digital-to-analog converters and amplifiers for producing the stimuli. It also provides
the precise timing essential to evoked response experiments.
