Sound Check

STANDARD INSTALLATION

∙Pull all faders down and engage the PSX’s STANDBY button to prevent unwanted feedback.

∙First, switch the PSX on and then the external amplifier.

∙In case you have condenser microphones connected to the PSX, you can now turn on the phantom power by pressing the PHANTOM switch.

∙Activate the PSX’s by pressing the STANDBY button again.

∙First, adjust the input levels of the microphones that are connected to the PSX. Please proceed as follows:

1.Set the corresponding gain controls and the channel faders to their lowest position.

2.Speak or sing as loud as possible into the microphone.

3.Use the gain control to adjust the level, so that even at loud passages the red PEAK LED is not lit but the green SIGNAL present LED lights constantly.

∙Adjust the EQ of the monaural input channels:

1.Slide the channel fader and the master faders up a bit, so that the sound is heard coming from the main speakers.

2.Turn the MID control carefully all the way to the right (+15dB). You should not hear any feedback.

3.Play the sound source or speak into the connected microphone.

4.Turn the frequency control (kHz) slowly from left to right.

5.You will detect the frequency range that is not to your liking or causing the feedback.

6.Leave the frequency control in this position and turn the MID control to the left until the sound is natural or to your liking.

7.If necessary, adjust the Hi and LOW controls, starting from their centered position, until the sound is pleasing to you.

8.Repeat the steps 1 - 7 for all monaural input channels in use.

∙In case you are also using the stereo input channels, you can adjust the levels in a similar way:

1.Set the LINE TRIM controls, the MIC gain controls, and the channel fader to their lowest setting.

2.Play the corresponding sound source at the highest volume that is to be expected during the performance.

3.Use the LINE TRIM control to adjust the level, so that even at loud passages the red PEAK LED is not lit but the green SIGNAL present LED lights constantly.

∙Adjust the EQ of the stereophonic input channels:

1.Slide the channel fader and the master faders a bit up, so that you can hear the sound through the main speakers.

2.Adjust the EQ controls at their center position.

3.Play the corresponding sound source.

4.Starting from the center position, you can adjust the controls until the sound is to your liking. Please, keep

in mind that major alteration of the EQ-setting does not necessarily result in the improvement of the overall sound. Especially when sound shaping is concerned, less can be more.

5.Repeat the steps 1 - 4 for all stereo input channels in use.

∙If musical instruments are connected directly to the monaural inputs, follow the descriptions above for adjustment of the microphones.

∙Make sure, that all channel faders, gain controls, and LINE TRIM controls of unused input channels are at their minimal setting. In this way you avoid unnecessary noise.
