INTRODUCTION
This manual is designed to help you get the most out of your L2A CS complete compact PA
system. The CS range is a range of powered mixer heads complete with speakers, leads and a
microphone.
The speakers have 10” and a horn in the CS408 system and 12” and a horn in the CS415. Both
have ‘top hats’ on the underside to enable you to place them on speaker stands (available from
www.musicgeardirect.co.uk).
It is the ideal system for any application from education use to rehearsal rooms. There are 4
separate channels to each of the mixer heads for multiple inputs. The mixer also has built in vocal
effects. This is the ultimate in cost affective ‘plug in and go’ PA systems. Please take time to read
through this manual to familiarise yourself with all the functions that are at your fingertips.
Front Panels of CS408 & CS415.
1. Bass. This is used to boost or cut the amount of bass or low frequencies to the channel. The
12 0 clock position is ‘0’. This is the optimum setting for the channel and indicates that bass
has not been either increased or decreased. Be careful not to wind in too much bass as this
could result in a low rumble type sound called feedback occurring and could potentially
damage your speakers.

2. Treble. This is used to boost or cut the amount of treble or high frequencies to the channel.
The 12 0’ clock position is ‘0’. This is the optimum setting for the channel and indicates that
treble has not been either increased or decreased. Be careful not to wind in too much
treble as this could result in a high whistling type sound called feedback occurring and
could potentially damage your speakers.
3. Level. This is to adjust the amount of volume to the channel.
4. EFX. This is to adjust the amount of reverb to the channel.
5. Mic. This is a low impedance input for connecting a microphone. Often referred to as an
XLR input.
6. Line. This is a high impedance input for connecting instruments, etc, or anything that
requires a ¼” jack. Please make sure that you are using a screened instrument lead and not
a speaker lead when using this input. They look very similar.
7. Master bass. This is to adjust the overall bass. As with the individual channel, the zero
position is at 12 0’ clock so bass can be reduced as well as increased.
8. Master treble. This is to adjust the overall treble. As with the individual channel, the zero
position is at 12 0’ clock so treble can be reduced as well as increased.
9. Reverb/Depth (on CS415). This is to adjust the overall reverb or DSP effect.
10. Footswitch. This is to plug in a footswitch to enable the effects to be turned on and off
(sold separately). This is useful for speaking in between singing.
11. Power. This is the power light that indicates that the mixer is switched on when
illuminated.
12. Master volume. This adjusts the overall volume to all channels simultaneously.
13. Music volume. This adjusts the amount of music volume coming into the mixer when a CD/
MP3/tape player, etc, is plugged into the Music in inputs.
14. Music in. This is used to plug a music source into. The inputs are via phono (sometimes
referred to as RCA) inputs. This cable is available separately from
www.musicgeardirect.co.uk.
15. Rec out. This is to plug any recording device into to allow you to record anything that is
plugged into the inputs of the mixer.
16. Graphic Equalizer (CS415 only). This allows you to cut or boost certain frequencies to help
enhance the mix. The middle of each graphic is your 0dB starting point. Frequencies tend to
be cut or ‘notched out’ more than boosted. Ideal if you are in a room which does not have
particularly good acoustics. You can use the graphic to cut certain frequencies that
sometimes tend to feedback.

17. DSP (CS415 only). This is a rotary knob that allows you to choose one of the 16 DSP effects
that are built into the mixer. A list of all effects is listed below

18. Power. This is to switch the mixer on and off.
19. AC Power connector. This is where the mains IEC plugs in. It also houses the internal AC
power fuse.
20. Speaker. These are outputs that connect to the speakers supplied. Please use the leads
provided. If longer leads are required they can be purchased from
www.musicgeardirect.co.uk.
21. Line out. This is used to connect the mixer to another mixer input source. This is useful if
you need to amplify more speakers for a larger application.
