6.3 Enabling Phantom Power e
IMPORTANT! WARNING! DANGER!
Always disconnect AC (mains) power and Telephone Circuits before
removing the Zephyr Xport’s cover.
Potentially lethal voltages are inside! Failure to observe the above
warning may result in electric shock, injury or even death!
Refer all servicing to qualified personnel. w
The Xport has a built in 12 volt (10 mA) phantom power supply for use with condenser
microphones. If your microphone requires a higher voltage, you will need to use an external power
supply. Follow the steps below to enable the phantom power supply:
1. Disconnect the AC (mains) power cord and all telephone connections from the rear
panel of the Xport.
2. Remove the rear bumper of the Xport by gently pulling at the top with your fingers
(see photo above)
3. Remove the 6 Phillips-head screws around the perimeter of the rear panel.
4. Grasp the rear panel and pull it out (see photo above)
5. Look at the bottom of the unit, and locate the green wire going to the power entry
module. Disconnect this green wire by unplugging it from the power module. Pull
the board out from the chassis.
6. Locate jumper JP-10. Remove the jumper block and relocate it to the two pins
closer to the rear of the unit (to enable Phantom power).
7. Re-attach the green wire removed in step 5
8. Carefully align the front edges of the circuit board with the lower pair of grooves on
the inside of the case, and carefully slide the circuit board into the chassis. If you
encounter resistance, remove the board, check the alignment, and repeat.
9. Replace the 6 screws removed in step 3.
10. Replace the bumper removed in step 2.
