PRODUCT SAFETY
This product is manufactured with the highest standards and is double checked in our quality control
department for reliability in the "HIGH VOLTAGE" section.
CAUTION
Never remove any panels, or open this equipment. No user servicable parts inside.
Equipment power supply must be grounded at all times.
Only use this product as described, in user manual or brochure.
Do not operate this equipment in high humidity or expose it to water or other liquids.
Check the AC power supply cable to assure secure contact.
Have your equipment checked yearly by a qualified dealer service center.
Hazardous electrical shock can be avoided by carefully following the above rules.
EXTRA CAUTION FOR LIVE SOUND
Ground all equipment using the ground pin in the AC power supply cable.
Never remove this pin. Ground loops should be eliminated only by use of isolation transformers for all inputs
and outputs. Replace any blown fuse with the same type and rating only after equipment has been
disconnected from AC power. If problem persists, return equipment to qualified service technician
PLEASE READ THE FOLLOWING INFORMATION
Especially in sound equipment on stage the following information is essential to know.
An electrical shock is caused by voltage and current, actually it is the current that causes the shock.
In practise the higher the voltage the higher the current will be and the higher the shock.
But there is another thing to consider and it is resistance.
When the resistance in Ohms is high between two poles, the current will be low and vica versa.
All three of these; voltage, current. and resistance are important in determining the effect of an electrical
shock.
However, the severity of a shock primarily determined by the amount of current flowing through a person.
A person can feel a shock because the muscles in a body respond to electrical current and because the heart
is a muscle it can affect, when the current is high enough.
Current can also be fatal when it causes the chest muscles to contract and stop breathing. At what potential is
current dangereous.
Well the first feeling of current is a tingle at 0.001 Amp of current.
The current between 0.1 Amp and 0.2 Amp is fatal.
Imagine that your home fuses of 20 Amp can handle 200 times more current than is necessary to kill. How
does resistance affect the shock a person feels.
A typical resistance between one hand to the other in "dry" condition could well over
100,000 Ohm.
If you are playing on stage your body is perspiring extensively and your body resistance is lowered by more
than 50%. This is a situation in which current can easily flow.
Current will flow when there is a difference in ground potential between equipment on stage and in the P.A.
system. Please do check if there is any potential between the housing of the mikes and the guitarsynth amps,
which will be linked by your body on stage. Imagine, a guitar in your hand and your lips close to the mike! A
ground potential difference of above 10 volts is not unusual, in improperly wired buildings it can possibly be as
high as 240 volts.
