Verify the ROKIT is the correct model for 
the AC power outlet. The ROKIT is 
available in different models for regions 
that have 100VAC, 110-120VAC, and 
220-240VAC power outlets. A mismatch 
can cause damage to the ROKIT and 
should be replaced with the correct 
model.
A ROKIT pair contains a left and right 
side. Confirm which ROKIT has no 
power. Move the power cable from the 
working ROKIT to the ROKIT with no 
power. If the no power ROKIT is now 
‘on’, the previously used power cable is 
the problem and needs to be replaced. 
If there is still no power, follow the 
checklist.
Check to see if the AC outlet is 
operating. Remove the power cord and 
replace with a known functional 
electronic device such as a lamp or 
charger for a mobile device.
Check that the rear panel of the ROKIT is 
not hot. Usage in direct sunlight, a hot 
room with poor airflow or excessive use 
at maximum levels may cause the unit 
to overheat and go into thermal 
protection. Turn off the power and 
allow the ROKIT to cool down. If this is 
not the problem, contact customer 
service.
Check that the fuse has not blown. 
Remove all power cords and signal 
cables from the ROKIT. With a flat-head 
screwdriver, remove the fuse cover and 
inspect the fuse (the filament wire 
should not be broken). If the fuse is 
blown, replace it with the spare fuse 
located in the fuse holder. If the fuse 
blows again, contact customer service.
…there is sound and it is bad (excessive 
hum and terrible hiss).
A ROKIT pair contains a left and right side. 
Confirm which ROKIT has the bad sound. 
Verify that both left and right ROKIT’s have 
identical knob settings. Then simply move 
the audio signal cable from the working 
ROKIT to the bad sound ROKIT. If the bad 
sound ROKIT produces good sound, the 
previously used cable is the problem and 
needs to be replaced. If there is still bad 
sound, proceed with the next step.
Disconnect the audio signal cable from the 
rear panel of the ROKIT. With the ROKIT 
powered on, listen for the bad sound (i.e. a 
slight hiss or hum). If the bad sound is no 
longer there, the problem is not the ROKIT 
and the audio source should be checked. 
Signal  cables  should  not  be  mixed  with 
power cables. If the ROKIT still has bad 
sound, follow the checklist below and 
review the “Check the audio source” box.:
Check that all audio equipment is 
connected to the same ground point. This 
means both studio monitors and audio 
source (laptop, mixer, audio interface) are 
connected to the same AC outlet ground 
point.
Check that the AC outlet is not connected 
to any electronics that can induce noise 
into the power line (such as light dimmers, 
neon signs, motors or climate control 
devices such as heaters, air conditioners or 
humidifiers). These devices should not be 
using the same AC circuit as the audio 
equipment. If the problem persists, look 
into adding AC conditioning equipment to 
clean the noise from the AC outlet or 
contact customer service.
