RZ6 Multi I/O Processor
RZ6 Overview
The RZ6 Multi I/O Processor is a high sample rate processor with
fl
exible input/output
capabilities. The RZ6 features up to four digital signal processors cards. Any card can be either
a single standard processor card (RZDSP) or a quad core processor card (QZDSP). Standard
single processor cards use a single Sharc DSP; quad-core processor cards use four Sharc
DSPs cores with the potential to more than double the power of the RZ6. All cards are
networked on a multiprocessor architecture that features e
ffi
cient onboard communication
and memory access. Two channels each of sigma-delta analog input and output provide a
dynamic range of up to 115 dB and sampling rates up to ~200 kHz.
The single device form factor incorporates two channels of onboard programmable and
manual attenuation and can drive headphones and standard, magnetic, or electrostatic
speakers. It includes an onboard monitor speaker, two channels of ampli
fi
cation for analog
inputs, and 24 bits of digital I/O. XLR, audio jack, and BNC connections are supported.
Optionally, the RZ6 can be equipped with a
fi
ber optic input, allowing it to support a four
channel Medusa preampli
fi
er.
The RZ6-A base version starts with a single DSP and makes an excellent all-in- one
psychoacoustics system or can be added to any system to add audio stimulus generation to
experiments.
The RZ6-A-P1 comes equipped with four DSPs for more processing power and includes the
optional
fi
ber optic input port, allowing it to serve as a BioAmp base station for ABR and OAE
studies using TDT's BioSigRZ software.
