Troubleshooting
Trouble Advice
Lost the AX44 fixing screws?
Replace with M3 x 6 mm machine screws.
Do not use screws longer than 6 mm as they
may damage the AX44.
The AX44 does not work and the Power
indicator is off?
Make sure that the computer is turned on.
Make sure the power connector is properly
connected to the AX44.
Make sure the supplied 20-pin cable is con-
nected properly between the AX44 and
DS2416.
The Power indicator is on but the AX44 still
doesn’t work?
A single AX44 should be connected to
DS2416 connector “IO-A”; the second AX44
to connector “IO-B”.
The input signal sounds distorted?
Reduce the level of the input signal.
When connecting line-level equipment to
inputs 1 and 2, set the Mic/Line switches to
Line.
The input signal is too quiet?
Low-level signal sources such as micro-
phones should be connected to inputs 1 and
2 and the Mic/Line switch set to Mic.
Cannot hear anything in the headphones?
The headphone signal is derived from out-
puts 3 and 4, so you must assign signals to
these outputs in order to use the head-
phones.
