Esoteric G-25U User Manual

Troubleshooting
No power.
→Check the connection to the AC wall outlet. Make sure the outlet is not switched by a lamp switch by
plugging in another electrical device to see if the outlet is “live”.
→Press the POWER switch of the unit to turn it on.
Word sync does not work.
→Frequency of the output word clock may be invalid to the connected components. Change the frequency
setting to match that of each component. There are occasions where the word sync setting of each
component can be changed by tying other connection or setting, read well the instructions of each
component.
Cannot select suitable frequency by pressing A, B or C buttons.
→Press MASTER button to select the base frequency before selecting frequency by pressing A, B or C
buttons.
Sound is strange.
→Check the setting and suitable frequency range of connected components. If the setting is not correct,
there are occasions where the reproduced sound is strange or contains excessive noise.
EXT indicator LED blinks.
→EXT indicator blinks when the EXT mode is on and the unit cannot detect the reference signal from
external devices, or the input signal is beyond the spec this unit can input.
When the EXT indicator is blinking, confirm the setting of the connected external devices. If you do not
use EXT IN terminal, turn off the EXT mode.
