SOUND MIXING TIPS FOR FIRST TIME USERS
Step 4: Add Effects

Reverb or echo effects can be used to add ambience and character to certain types of
audio sources, particularly vocals.

Select the type of effect required using the FX section SEL buttons.

Send some audio signal to the FX bus by turning the FX control clockwise on your
preferred channel - try a vocal channel first.

Gently raise the FX master fader (yellow) to add the effect to the main stereo mix.

Be subtle when it comes to adding effects - too much will smother the original sound.
Keep the FX send controls turned down on other channels so they don’t add to the mix.

If you are using the AUX bus on your ZED to feed signal to a stage monitor (often called
foldback) then it is possible to add some effects signal to this mix by using the FX to
AUX control in the FX section.

It is usual to mute effects used for singers when they stop singing and talk instead.

The FX send control on the channel sends audio from after the fader so the amount will
stay in relative proportion to the fader level. In other words, you don’t need to turn the
FX send control down when you reduce the fader, it follows automatically.
Step 5: Using the AUX bus for feeding a stage monitor

The Auxiliary bus can be used to create an independent mono mix of audio signals.

There are many uses for Aux buses, but a common one is for artists monitors.

Connect the AUX Out to an amplified monitor speaker which can be positioned close to
the performers, or switch the AUX Out to feed the ZED POWER 1000 Amplifier Outputs.

Increase the AUX Mix level (master) control by turning it clockwise.

Create your monitor mix by turning up the AUX send level controls on the channels that
you require in the monitor speaker. The AUX send level controls are sourced from be-
fore the channel fader so they will not be affected by it, therefore remaining independ-
ent of any movements made on the faders to balance the main stereo mix.
Step 6: Control feedback

Be aware that amplified signals from microphones are usually able to feed back to the
microphone and will, if loud enough, cause a feedback loop with howls or whistles.

Feedback loops can be controlled by careful placement and use of uni-directional mi-
crophones, placement of speakers and correct microphone technique which will re-
duce the need for increased gain or level in the system. The 9-band GEQ on the Ampli-
fier Outputs can also be used to prevent and control feedback.
Step 7: Interval music

If your application is a performance where background music is required, you can con-
nect an MP3 / CD player to the Playback input or a computer to the USB interface.

Mute all channels (leaving the faders set) and then the background music can be sent
to the main left-right mix by raising the Playback fader.
