Quick Start

Basic Setup

The following section explains the basic setup and operation of the S4000.
1. Before connecting mics or instruments, make sure that the power of all your systems compo-
nents, including the S4000 mixer, is turned off. Also, make sure that the volume and gain
controls of each channel of the S4000 and the MAIN, MONO, AUX 1 and AUX 2 level faders
are turned all the way down.
2.
Make the connection to your speakers, using heavy gauge, unshielded speaker cable, from the
S4000 Speakon® or ¼" speaker outputs.
3. Connect the cables to your microphones and instruments, and insert the other end of the cable
firmly into the appropriate inputs on the S4000.
4. Switch on the power of any peripheral devices, and then power up the S4000.
NOTE: Since the S4000 contain two internal power amplifiers, it is important to remember the
Golden Rule of audio ... "LAST ON, FIRST OFF". Translated, this means that when powering up
your PA system, you should always turn your power amplifiers on LAST, and when power your
system down, turn your power amps off FIRST. This helps avoid any loud pops caused by in-
rush current at power up or power down, which can sometimes damage loudspeakers.
5. Make sure the channel faders are all down, then set the MAIN level fader control to the unity
or "0" position.
6. Before you turn up a channel, you want to make sure you set a good level, with no distortion,
on the channel input GAIN. While speaking into the mic at performance level (or playing the
instrument), adjust the channel GAIN control so that the "PEAK" LED of the channel lights
occasionally, then back it down slightly.
7. Once you have set the GAIN control, slowly adjust the channel LEVEL fader control until the
desired level is reached.
8.
If you wish to adjust the tone of each channel, adjust the equalizer controls as desired. You
may have to re-adjust the channel volume.
9. Use the MAIN STEREO GRAPHIC EQ section graphic equalizer and MASTER control to adjust
the overall volume and tone. You can increase the overall level of your system by cutting cer-
tain frequencies that cause feedback.
