The EZ-Extender consists of three Analog Devices AD1939 audio codecs
and provides 24 channels of analog audio out, 12 channels of analog audio
in. The primary codec operates in both in I
2
S and TDM mode and can
run at sample rates of 48, 96, or 192 kHz. The other two codecs are con-
figured to operate in dual line TDM mode. The three codecs together can
operate in dual line TDM mode for 24 analog channels out and 12 analog
channels in at a sample rate of 192 kHz.
The audio input and output is available via multiple RCA connectors. A
group of switches is available if a user should decide to evaluate the audio
codec inputs and outputs in a differential mode.

DB25 to XLR cables are not supplied with the EZ-Extender.
