GENERAL
The EXP9 is a Nine Zone Expansion unit designed to work exclusively with the ZPR68-10 Six Zone Eight
Source Remote Preamp. When connected to the ZPR68-10, it allows expansion up to a total of 15 zones.
• The features, functions and performance of the zones on the EXP9 are identical in every way to those of
the ZPR68-10.
• The EXP9 is available with one to nine "XCARDs" (zone expansion PCB's) pre-loaded and tested at the
factory, or, individual XCARDs may be purchased for in-field expansion.
• When received from the factory, unused zone openings are covered from underneath with individual cover
plates. These are removed, as needed, when additional zone XCARDs are installed in the field.
• CAUTION: The EXP9 cannot operate by itself. It must be connected to a ZPR68-10. Also, it will not
operate with the original ZPR68 (older version).
• The EXP9 connects to the ZPR68-10 via two multiconductor ribbon cables (included). One is a 26-
conductor cable, the other 50.
• As with the ZPR68-10, the EXP9 uses a multi-voltage high-current AC power supply (included).
• Control of all zones is also possible via the COM PORT (RS232 data signal compatible) on the connected
ZPR68-10.
• As with the ZPR68-10, the EXP9 operates with IR commands from the Xantech RC68 IR Remote/
Programmer (available separately). As received from the factory, each zone (as well as the XCARDs)
is set to IR Code Group number 68.

Summary of Contents for Xantech EXP9
- Page 1 Source Remote Preamp. When connected to the ZPR68-10, it allows expansion up to a total of 15 zones. • The features, functions and performance of the zones on the EXP9 are identical in every way to those of the ZPR68-10.
- Page 2 5. STATUS DRIVER PINS. These pins allow connection to STATUS LED's located in an optional rack mount panel. The LED's are driven from the individual status lines of each zone (9 total for the EXP9), allowing visual indication of zone ON/OFF condition at the front of the rack panel.
- Page 3 9. Video Gain Adjustment Jumpers (Internal. Refer to Fig. 3). As with the ZPR68-10, the video gain of each zone on the EXP9 can be set to two levels, by the use of an internal jumper. With the jumper on one pin only of PJ1, the video gain is unity (0 dB). When the jumper is inserted onto both pins of PJ1, the video gain is increased by +3 dB.

2. Be sure the EXP9 is not powered (unplug the power supply from the EXP9). 3. Remove the top cover by removing the five screws on each end of the EXP9 and the screw just under the Video jacks on each of the existing Zone Outputs. Carefully lift the cover off. -
Page 5: Power Supply Considerations
's (2 in some zones, 3 in others, with Status) and eighteen 780-80's (2 per zone, with Status), are connected to the zones on the EXP9. Add up the currents: (24 x 90 mA) + (18 x 30 mA) = 2700 mA total current. -
Page 6: Troubleshooting
NOTE: The 782-00 Power Supply has a capacity of 1000 mA. If you have a system that is so extensive that the total current exceeds the 1.8 A limit of the EXP9 by more than 1000 mA, use two 782-00's connected so that two separate +12V DC rails are created. - Page 7 IR noise may be entering one or more of the IR receivers in the zones. This would interfere with the proper recognition of the IR codes. Take steps to remove the IR noise or use Xantech IR Receivers with high noise immunity (the CFL types).
