DUAL STEREO LINE MIXER is a Line mixer designer especially for guitar systems.

Now you can easily mix signal from your amplifier with line signals coming from
effects processors. The result? A fundamentally lower noise ratio and overall, non­digitalized warm, analog sound. Additionally, its small size and flexibility make it
useful for small keyboard systems or anywhere, where a small mixer is needed.

Many people think over about how to force their guitar systems to sound like John
Petrucci or The Edge.. However, not many know how their advanced control systems
look like. We would therefore like to get you a step closer to the world’s top. One of
our line mixers, which you may find in our product line will definitely help you
achieving better level in your sound quality.

This device converts a serial signal into a parallel signal thanks to which we can mix-in
effects (delay, reverb, chorus, flanger, etc.) to a base signal undistorted by digital
processing. This idea comes from recording studios worldwide, where a base signal is
mixed with effects from consoles, thanks to which it does not lose clarity while gaining
‘spaciousness’. If you want your guitar parts to never get lost in the mix, to be spacious

and breathable and, most of all, if you do not want to distort your signal with

additional noise this is a device you’ve been looking for..

FRONT PANEL

1. Power LED

2. MIX level controls : Stereo volume for MIX 1 and MIX 2.

Gain for LINE level is set with the knob at 11 o'clock.
Gain for GUITAR level is set with the knob at 14 o'clock.

REAR PANEL

All of the 1/4 inch jacks on the rear panel are for UNBALANCED mono plugs.

1. EXT IN: These outputs carry the same signals coming in the "Mix 1 In 1"
inputs. Enables you to feed these signals somewhere else without having to use
Y-cables.

2. Mix 1 Inputs: Four stereo, line level inputs to Mix 1.

3. Mix 1 Out: Two separate identical sets of Left and Right line level outputs

from Mix 1.

4. Mix 2 Inputs: Four stereo, line level inputs to Mix 2.
IMPORTANT: MIX 2 IN is controls the internal normal connection from
MIX 1 to MIX 2. If nothing is plugged in to these input, output from MIX 1 feed
through to MIX 2. If something is plugged in to these inputs, the internal MIX 1
& MIX 2 connection is broken.

5. Mix 2 Out: Left and Right line level outputs from Mix 2.

6. Ground/Lift switch

7. POWER: 9-12 VAC /300mA or 9-12 VDC / 400mA

Mix 1

Mix 1 consists of four pairs of Left and Right
inputs, two External split outputs, and two pairs of MIX 1 outs. All of these jacks are
for mono plugs, and are intended for line level signals.
For mono signals, use only the Left input and the signal will feed into both the Left
and Right channels.

After the four inputs are combined, their overall volume is controlled by the MIX 1
knob on the front panel, and the resulting signal is passed to the two sets of Mix 1 Out
jacks.

Mix 1 In 1 and the External Split

You will blend the outputs of your effects with the pure tone of your preamp. In most
cases, the output of your preamp (or your amp's effect send) will be connected to Mix
1 In 1. The External Split outputs are copies of the signal coming in Mix 1 In 1. These
outputs are used to drive the inputs of your effects devices.

Mix 1 Outputs

There are two separate identical stereo pairs of outputs for Mix 1. Mix 1 is also
internally connected to Mix 2. These outputs can be used to drive the inputs of more
stereo effects devices for a second "stage" of processing. The outputs of these effects
can then be connected to Mix 2 inputs. In this way you can have two stages of parallel
effects, one cascading into another. In Section 6 you will see how it all comes together
in a system.

Mix 2

Mix 2 consists of four pairs of Left and Right inputs, and one pair of MIX 2 outs.
After the four inputs are combined, their overall volume is controlled by the MIX 2
knob on the front panel, and the resulting signal is passed to the Mix 2 Out jacks, and
to the Cabinet Simulator circuitry (which feeds the rear panel Direct Outs and the front
panel Balanced Outs).

Mix 2 In 1

If the Mix 2 In 1 jacks are empty, the stereo output of Mix 1 will be fed into Mix 2.
Inserting a plug into them will break this normal connection between the
two mixers.

Mix 2 Outputs

The Mix 2 Outs carry the sum of all the Mix 2 inputs. This is the output to connect to
your power amp, or to your amp's effect return jacks. If you need an output with the
Cabinet Simulator, then use the Direct or the Balanced Outs instead.
