normally. Please note any such messages and be ready to report them to Orban Cus-
tomer Service.

The DSP chips are located on the DSP board — see the drawings starting on page 6-
52. U701 and U702 are local voltage regulators on the DSP board that derive the
+3.3V supply for the DSP chips from the system digital 5V bus.

Power Supply

Warning!

Hazardous voltages are present in the power supply when it is connected

to the AC line.

The power supply converts an AC line voltage input to various power sources used
by the 9400. To ensure lowest possible noise, four linear regulators provide



15VDC

and



5VDC for the analog circuits. A switching regulator provides high current

+5VDC for the digital circuits. An unregulated voltage powers the fan and feeds lo-
cal regulators.

The power supply circuits are straightforward and no explanation is required be-

yond the schematic itself. Be aware that C1, C4, C5, and C12 in the
switching regulator are premium-quality low-ESR capacitors and must be
replaced with equivalent types to ensure proper operation of the switch-
ing supply.

The output of the power supply is monitored by the power-indicator LED circuit,
which causes the power LED to flash according to a preset code to diagnose prob-
lems with the various power supplies in the 9400. See step (2.B) on page 4-8.
