these inputs. Be aware that this supply is not isolated from the others. This defeats the opto iso-
lation and there is a possibility of AB/DR-3000s getting ÔzappedÕ through this connection.
The DR-3000 can only be attached as shown above for ÔExternal PowerÕ. The AB-3000 has
the option of running from ÔInternal PowerÕ. This allows simple Ôswitch closuresÕ to be used with
the AB-3000. As with using the 24 VDC output from the PS-200, this reduces the protection af-
forded the AB-3000 by the optoisolator inputs.
d) 1/2 J6/A VCA Inputs: Twenty position enclosed header compatible with IDS-20 connectors.
This connector is used to run up to eight 0 to 10 VDC control signals to the DR-3000 and DR-
4000s installed in this card cage. These can be used to remotely control the volumes and
other analog adjustments on the DR-3000s. The impedance of each input is 20 Kohms. The
pinout is as follows:

On the AB-3000 AudioBricks, only two of the eight analog inputs are brought out to screw
terminals on the outside of the case. The remaining six inputs are available inside the case if
you need to use them.
e) Power Supply: Four position screw terminals on revision 1.0 backplanes, six positions on all
later ones. This connector is wired in parallel with the AUX. POWER connector. The screw termi-
nal is used on CC-3016 cad cages for attaching it to a PS-200 power supply. The AUX. POWER
connector is used on CC-3004 card cages. The pinouts for the screw terminals are
silkscreened on the backplane.
The two ÔsenseÕ terminals are used to feed voltage information back to the PS-200 power
supplies so that the five volt regulation is more stable. On the earlier (1.0 revision) CC-3016
backplanes, the sense inputs to the PS-200 should be connected to the AUX. POWER connec-
tor.
f) Aux. Power: Five position 180¡ DIN connector 18 . This connector is wired in parallel with the
POWER SUPPLY screw terminal. The screw terminal is used on CC-3016 cad cages for attach-
ing it to a PS-200 power supply. The AUX. POWER connector is used on CC-3004 card cages.
The pinouts for the screw terminals are silkscreened on the backplane. The pinout for the ALT.
POWER connector is as follows:

18 Use extreme caution when making discrete wire connections to the AUX. Power, as five pin 180¡
DIN connectors are numbered 3, 5, 2, 4, 1 as you face the socket on the back of the card cage.
