Trouble Shooting
Although the greatest care has been taken in the manufacture of this mixer, the possibility remains that faults could occur during use or difficulties
could be experienced during initial installation.
The cause, however, will rarely be found to be internal to the be the mixer. Below is a list of symptoms and possible causes. Some of the
suggested causes may appear obvious , but they can be easily overlooked.
Under no circumstances should you open the mixer; as this is dangerous, and will expose you to mains voltages; it will also invalidate all rights
under the guarantee.
1.
After turning on the 'power' switch the 'power' indicator does not light-
The mains plug is not pushed far enough into the mixer.
Check there is a supply to the mains socket.
Check supply using an alternative electrical appliance.
The mains input fuse is broken, at back of mixer, replace using QB 250mA 20mm fuse.
2.
When the controls are advanced no sound is heard-
Check the input signal is connected to input socket.
Check the input signal is connected to channel being used
Move input plug to another channel, or use controls on connected channel.
3.
Even when the output is low, the output sounds distorted-
Check the input gain is not too high - peak LED will be on
Check the input signal is not too high - peak LED will be on
4.
Condenser mic not working
Check the 48 phantom power on
Check the mic is plugged into a mic channel 1 – 4 only
Check the mic cable a balanced 3 wire type
As a general rule jack plugs and sockets are very reliable especially if they are regularly connected and disconnected. In situations where they are
subject to prolonged static use - it is good practice to clean the plugs and to clean the sockets by taking a new plug and waggling it in & out. this
will stop any build up of any corrosion.
