If Problems Persist
The Cinénova 7300 is protected with optical short circuit protection. If it is tripped, the
shorted channel will mute and reset every 7 seconds. If fault remains, it will stay in mute
mode. We recommend to swap the speaker with a guaranteed working speaker and see
if the channel works.
Circuit Protection
The following maintenance should be performed routinely:
�
Clean the exterior surfaces of the unit with a soft, dry, lint-free cloth.
�
Do not use alcohol, benzene, acetone-based cleaners, or strong
commercial cleaners.
�
Do not use a cloth made with steel wool or metal polish.
�
If the unit is exposed to a dusty environment, a low-pressure blower
may be used to remove dust from its interior & exterior.
Maintenance
Often humming noise is emanating from equipment that have their ground prong broken.
To isolate this problem:
a) With the amplifier OFF, unplug all RCA’s connected to the amp.
b) Turn on amp and listen to speakers. If buzz has changed or reduced in level, then the
problem is coming to the amp from another source. The rest of the hum you hear is
normal and related to the fact that the RCA’s are open ended.
c) The above step should isolate your problem: star-ground all components, except
amplifier, by daisy-chaining a thin wire from the processors chassis to all sources
connected to it.
Humming Noise From Speakers
It is normal when running the amplifier to full power that the LED's flicker. If the LED's
are on constantly without flickering (solid orange) it means that the amplifier output is
clipping. Reduce volume level to prevent damage to speakers or amplifier.
