Trouble Shooting and Maintenance

Troubleshooting Cinénova Grande 5 or 7

Peak LEDs “ON” Constantly

Amplifier “ON” No Sound

It is normal when running the amplifier to full power that the LEDs flicker. If the LEDs 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.

Humming noise from speakers

Often humming noise is emanating from equipment that have their ground prong broken. To isolate this problem:

a)With the amplifier OFF, unplug all RCAs 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 RCAs 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.

Maintenance

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.

Circuit Protection - For Cinénova 7 only

The Cinénova 7 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.

a)Completely shut your system down, including your Cinénova via the circuit breaker.

b)Now turn on the Cinénova only. Check to see if the front Main Power Switch is on.

c)Check the Input Selector switch and make sure that it is in the correct position. Either RCA or XLR which ever you are using. Also slide the Input Selector switch back and forth to ensure good contact.

d)Set the crossover switch so that it is centered. Slide it up and down and finally back to the middle position.

e)Confirm that the output wires are connected to the speaker.

f ) Rock the crossover switch back & forth at the amplifier, you should hear a thump through the speaker during this process.

WHEN A THUMP IS HEARD:

g)Check your input source signal. Make sure they are connected properly to output from processor/source, (not input of processor).

h)Try to change source to make sure that at least one of the sources works.

WHEN NO THUMP IS HEARD:

i)Check amplifier speaker connections.

j)Make sure the speaker wires are securely connected to the amplifier speaker output and to the speaker. NOTE: It is possible that if you have proper connections and you don’t hear sound, the speaker is burnt.

Turn amplifier ON and circuit breaker shuts down

This can either be a short in amp, a poor circuit breaker in the house or the power cord is not fully connected. Plug amplifier into another outlet on a different circuit breaker with nothing connected. If the amp turns on then the problem is with your home circuit breaker. If the amplifier still does not power up, please call Earthquake to consult with a technician.
