TROUBLE SHOOTING
No Power.....
Check mains lead/A.C. power cord is connected and pushed in firmly.
Is there power at the A.C. wall outlet?
Is the Horizon switched on?
No sound.....
Is there an input signal?
Are the speakers connected?
Are the channel and output faders raised?
Is the channel MUTE or the STANDBY switch on?
One or both speakers reduce in volume for a few seconds and then returns to full volume …
One or both amplifiers are overheating. This can be caused by one of the following:
Amplifier(s) being overdriven, red 1000W LED constantly illuminated - Reduce MIX faders until the signal
only briefly flashes the red LED.
Using speakers with a final impedance less than 4ohms Check speakers for the correct impedance.
Not enough ventilation ensure the front and rear of your Horizon is not obstructed and receives a good
supply of cool air.
Glossary of technical terms
AC or a.c. Alternating current.
AC POWER SUPPLY Local electrical supply
ASSIGN To switch or route a signal to a specific signal path.
ATTENUATE To reduce or make quieter.
BALANCED Balanced 3 connection circuitry is widely used in audio equipment from cheap dynamic
microphones to top quality studio devices. The balanced system is used as it cancels outside interference
in the connecting cables resulting in a cleaner signal.
BANDWIDTH The bandwidth is the range of frequencies that will pass through a piece of equipment.
BUS A common conductor that carries a signal, or number of signals, through a mixing console.
CLIPPING Distortion caused by a signal exceeding the maximum level that an input can accommodate.
COLD The negative phase of a signal. Usually the black wire in a balanced cable. For an unbalanced signal
the SCREEN is used for the COLD connection.
COMPRESSOR An electronic device used to reduce the level of a sound increasing above a set threshold point.
Often used on vocals to achieve a more consistent volume level. A compressor can also be used to keep signal
levels from overloading the input of a piece of equipment.
CUEING Another word for monitoring, usually when a signal source is prepared to be played at a specific
time during a performance. It may be a sound effect for a stage production or an MP3, CD or MD track being
available to play so that the music is ready to start immediately.
dBA The most commonly used unit for measuring sound pressure levels. The 'A weighting' takes account of
the ear's varying sensitivity to different frequencies, which is most pronounced at low volumes.
