Speck Electronics EQ16 - Manual (Page 18)

There are no special requirements for installation and interface of the
EQ16 to the Xtramix except to use reasonable care in the layout of the
audio wires.
It is recommended that the EQ16 be installed directly above or below
the Xtramix. This will allow you to keep the cable lengths short,
thereby reducing the susceptibility to hums and buzzes caused by EMI
emissions.
The EQ16 may be connected to virtually any signal path of the Xtramix.
One choice is to connect any number of stereo synths into the stereo
inputs of the Model EQ16-32 and the respective outputs of the EQ16-32
to the first 16 stereo inputs of the Xtramix. The following illustrations
(Figure 6 and Figure 7) show two recommended methods of connecting
the EQ16 to the Xtramix.
A balanced 1/4" TRS to 1/4" TRS audio cable is required for each "EQ
Out" to "Xtramix In" connection to be made. If the EQ16-32 is used, it
would require 32 cables for connection to the Xtramix.
The EQ16 may also be interfaced to the 8 subgroup patch points for
overall equalization of the assign subgroups, or the effects returns for
equalization of up to 8 stereo effects devices.
A special cable will be required if the EQ16 is interfaced to the
subgroup insert jack. This cable should be wired with a stereo 1/4" TRS
plug on one end, and (2) mono 1/4" TS plugs on the other ends (See
figure 5a and 5b in chapter 3). The ring of the stereo plug is the
subgroup insert output, this connects to the EQ input. The tip of the
stereo plug is the subgroup return, this connects to the output of the
EQ16.
A complete set of interface cables necessary to connect the Model EQ16
to the Xtramix are available from Speck Electronics.
