For the best results, you should use the maximum D/A voltage range and use the attenuators
to reduce the output to the target voltage.
Manual Attenuator
The RZ6 includes another level of analog attenuation that can be
controlled manually via the attenuator control knob from 0 to 27 dB in
increments of 3 dB.
Manual attenuation is applied to both channels before the signals are
output on any of the front panel connectors and is therefore applied in
addition to any programmable attenuation.
Analog Output via BNCs
DAC channels A and B are output to BNCs labeled Out-A and Out-B
after attenuation has been applied. These outputs use a stereo
power ampli
fi
er to drive TDT's MF1 multi-function speakers.
A single signal generated or input from any of the RZ6 analog inputs
can be ganged to reduce the spectral variation in power of the transducer across all
frequencies. To do this, con
fi
gure your signal to output from both DAC channels and connect
your transducer to both channels.
Stereo Headphone Output
DAC channels A and B are also available as a stereo headphone output through two
⅛
" audio
jack connector ports (channel A is the left stereo output and channel B is the right stereo
output). The port labeled A&B (top) provides a stereo headphone output suitable for
experimental paradigms while the port labeled Mon (bottom) can be controlled by the Mon
Level knob located directly to the right, making it more suitable for monitoring the experiment.
