Tips:
Before you power up please make sure that the master volume knob is down!
When switching o please also turn the main volume all the way down, as the removal of power can cause a loud “POP” as
the control circuitry will shut down before the amplier stage.
When connecting any audio device to an amplier, ensure the volume is turned down during the plugging in & unplugging as
loud noise can be generated. This is especially critical for microphones as they have a sensitive input.
When using microphones for public address, it is wise to ensure wherever possible:
• the microphones are kept as far away from the systems speakers
• keep the microphone behind the front row of speakers and try not to aim the microphone at the speaker,
• turn the volume of the microphone level up slowly if any unwanted noise is heard turn it down slightly, this is likely to
be the level of amplication for your room.
Excessive amplication of the microphone will cause it to pick up its own sound from the speakers and amplify it again
causing audio feedback, its volume control must be turned down to regulate this.
While using a microphone if you walk around the room, as you get close to the speakers this feedback may also occur,
so you either keep further away from the speakers or adjust the volume down.
It is good practice to do a sound check prior to any live event to establish the ideal and maximum levels, these may need to
be tweaked during the performance or as the room lls up as the acoustic properties of the room will change.
Microphones always work best when they are close to the audio source (your mouth) the further away the less signal they
will have to amplify. If you move the microphone closer and further away from you during its use the volume that your
audience will hear will vary dramatically. Keep speaking in a constant level, keep the microphone in a constant distance from
you and everything should be OK.
When using wireless microphones, top tips are test its range, if it is a critical event always t new batteries before the show,
ensure the microphone is turned o immediately after you have used it, check the user knows how to use the microphone.
