4.3 The 3 BANDS EQUALISER

A 3-band equaliser is provided for all input channels with a wide range of frequency adjustment.

4.4.1 HI

This is the treble control. You can use it to get rid of high frequency noises or to boost the sound of cymbals or the high harmonics of the human voice. The gain range goes from -15dB to +15dB with a center frequency of 12 kHz.

4.4.2 MID

This is the midrange control. It can affect most fundamental frequ -encies of all musical instruments and human voice. An attentive use of this control will give you and very wide panorama of sound effects. The gain range goes from -12dB to +12dB and the center frequency is 2.5 kHz.

4.4.3 LOW

This is the Bass control. Boost male voice or kickdrum and bass guitar. Your system will sound much bigger than what it is. The gain range goes from -15dB to +15dB and the center frequency is 80 Hz.

4.5 AUX

This control will send the audio signal to the Auxiliary Bus. The configura- tion is post-fader so the level sent to the AUX bus will be affected by the Main Level Control of that particular channel.

Note: There is the possibility to configure this AUX Send as Pre-fader as we will explain later in this Manual.

4.6 PAN

This is the PANORAMA control, or balance control. You can adjust the stereo image of the signal via this Control. Keep this control in center position and your signal will be positioned in the middle of stage. Turn this control fully counterclockwise and the signal will be present only on the left speaker and vice-versa.

Of course a wide number of intermediate positions is available.

4.7 PEAK

Inside your S-6 the audio signal is monitored in several different stages and then sent to the PEAK Led. When this Led blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK Led will blink with a level that is 6dB before actual clipping.

4.8 LEVEL

This Control will adjust the overall level of this channel and set the amount of signal sent to the Main output.
