1. INTRODUCTION

Thank you very much for expressing your confidence in products by purchasing L-6 6-Channel MixingLTO LTO
Console with Digital Effects. The L-6 is the smallest among our range of mixing consoles with digital effects. You will
get the smooth, accurate more natural and open sound from this apparatus, and it is really ideal for small gigs, record­ing and fixed PA installations.

The L-6 6-Channel Mixing Console with Digital Effects is packed with features that can not be found in other consoles
of its size: 2 mono (these are provided with Ultra Low Noise microphone preamplifiers and Phantom Power at +48

Volt) and 2 stereo input channels, and each of them is provided with a 3 bands graphic equaliser for HI, MID and LOW
controls

mix, control room / headphone outputs.

Your L-6 is very easy to operate but we advise you to go through each Section of this Manual carefully. In this way
you will get the best out of your L-6.

; built-in effects processor; highly accurate 6-segment bar graph meters and 2-Track inputs assignable to main

2. FEATURES

The L-6 6-Channel Mixing Console with Digital Effects is designed for professional appliance. It will provide the follow­ing features:

2 MIC input channels with gold plated XLR and balanced LINE input

2 stereo input channels with balanced TRS jacks

Ultra-low noise discrete MIC pre-amps with +48V Phantom power

Extremely high headroom offering more dynamic range

Balanced inputs for highest signal integrity

Warm, natural 3-band EQ on each channel

Built-in digital effects processor

Peak LED on each channel

AUX send per channel for external effects and monitoring

Main output, Control room and headphone outputs are unbalanced type

2-Track inputs assignable to main mix, control room / headphone outputs

Highly accurate 6-segment bar graph meters

3. READY TO START?

3.1 There is a small black box provided with your L-6. This is the specific AC input Adapter. Connect the proper terminal
into your L-6 and the Adapter into an AC socket.

3.2 Be sure that the main power switch is turned off before connecting the AC Adapter. Also, you should make sure that
all Input and Output Controls are turned down. This will avoid damages to your speakers and avoid excessive noise.

3.3 Before turning on the L-6 you shall connect it to a power amplifier and turn-on the mixer BEFORE the power amplifier.
Once you have finished your working session you shall turn the mixer off AFTER the power amplifier.

3.4 Before disconnecting the AC Adapter always turn-off your L-6.

3.5 Do not use solvents to clean your L-6. A dry and clean cloth will be OK.

4.1 The MIC/LINE channels

1

These are Channel 1 and Channel 2. You can connect balanced, low impedance
microphones to the XLR socket. ON the 1/4" phone jack you can connect either
a microphone or a line level instrument. You shall never connect an unbalanced
microphone to the XLR socket if you do not want to damage both the Microphone
and the Mixer.

4.1.1 PHANTOM POWER +48 Volts

It is available only on the XLR input sockets.

4.2 INPUT LEVEL setting

2

This Control is provided with 2 different indication rings: One is for the Mic­rophone and the other for the Line levels. When you use a microphone you
shall read the OUTSIDE ring (0-60dB); When you use a Line level instrument
you shall read the INSIDE ring (+15~-45dB). For optimum operation you shall
set this control in a way that the peak LED will blink also occasionally in order
to avoid distortion on the input channel.

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 12kHz.

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 2.5kHz.

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 80Hz.

4.5 AUX

7

This control will send the audio signal to the Auxiliary Bus. The confi­guration 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.
In this typical compact unit, the channel signal is not only assigned to
external effect or processor equipment directly but also to internal on­board effect module.

4.6 PAN

8

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.

that you are reaching signal saturation and possible distortion. The
PEAK LED will blink with a level that is 6dB before actual clipping.

5. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your L-6. However, we advise
you to read carefully the following section to be the real Master of your own Mix. Not paying attention enough to the
Input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a
corrupted signal or no sound at all. So you should follow this procedure for every single channel:

- Turn down all Input and Output Gain Controls

- Connect phantom powered microphones before switching on the +48Volt Phantom Power switch

- If you have a power amplifier connected to your L-6 set the Level of the amplifier at no more than 75%

- Now, set the CONTROL ROOM/PHONE level at no more than 50%. IN this way you will be able to hear later what
you are doing connecting a pair of headphones or a pair of powered studio monitor speakers.

- Position HI, MID and LOW EQ controls on middle position

- Position panoramic (PAN) control on center position.

- With a headphone or studio monitor speakers connected apply a Line Level input signal so that the PEAK LED does
not light up.

- At this point increase the input gain so that the PEAK LED will blink occasionally. IN this way you will maintain good
headroom and ideal dynamic range.

- Now connect a microphone and ask the singer to sing loud into the microphone. Turn slowly the Gain Control clock­wise and have the PEAK LED blink only occasionally

- Now repeat the same sequence for all input channels. The Main LED Meter could move up into the red section. In
this case you can adjust the overall output level through the MAIN MIX control.

6. FOR THE EXPERTS WHO WANT TO KNOW MORE

As we have told you previously in this Manual, the Aux Send Control both on Mono and stereo channels is factory wired
as POST-FADER. If you have some skill in electronic components soldering you can modify this setting and have all
your AUX sends configured as PRE-FADER.
