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.
