Preface by the developer The design and engineering of the originate from Germany. All components, and the equipment and installation, are manufactured exclusively by domestic partners to the highest quality standards. This allows us to implement ideas consistently, sustainably, quickly and efficiently.

1. Important safety instructions This document must always be read before commissioning for the first time and must be kept available at the location of use. It contains fundamental instructions that need to be observed during use. In addition, and in particular, the applicable directives and regulations issued for the location of use must be observed.
2. General instructions before and during commissioning: Danger of electrocution! Do not carry out servicing and repairs of any kind yourself inside the housing. Always use our trained service personnel or an authorised expert for servicing and repairs. Faulty connection of the product can lead to life-threatening injuries caused by the electrical power.
3. General Descriptions Phantom Power Microphones and other signal sources often require a separate power supply from a battery, rechargeable battery or power supply. Today, this effort is avoided by supplying connected signal sources with power via the signal cable (microphone cable etc.). Therefore, a supply voltage is coupled to the signal wires of the connection cable in the input of the mixing console.
Balanced Transmission Balanced transmission is preferred for the application of very weak signal sources such as dynamic microphones etc. It is also recommended to be used for longer cable lengths. Its major benefit is its insensitivity to disruptions such as humming noises and interfering signals i.e.

-> Decibel. Deci -> means a tenth. Bel(l) -> was a physicist (telephone etc.), after whom this unit was named. The unit dB has a logarithmic measure and represents the ratio of the input and output voltage, or the input to the output sound level. The most relevant values with their effects in the fields of sound and stagecraft can be seen in the following table Value Ratio...
LEDs. The scale on VU meters of this type is either in % or in dB. On mixer desks and amplifiers we often use just a single, generally red, LED for the indication. This indicates an impending over-modulation or undesirable distortion of the input signal by lighting up.
H/L – changeover H = High L = Low The designations H and L stand for the impedance (the input resistance, the apparent resistance Z) of the input circuit of amplifiers. A “high impedance” (H) stands for a high input resistance, a “low” (L) stands for a low input resistance. High impedances are normally required for pickup heads having piezo elements without their own pre-amplifier.
Phase Phase = Phasing The “Phase” or phase reversal switch has an important function. As the word Phase says, it changes the phasing of the signal by 180°. It changes the phasing, so to say. We need to use a little physics to make this clearer.
True Bypass true = real, genuine bypass = avoidance, bridging Bypass means avoidance. Here it means the “Non-Use” of a switch section (EQ, compressor etc.). Such Bypass switching normally takes place in the “simplest” way. The output of the circuit section is decoupled from the signal path.
High-Pass - Low-Pass - Band-Pass A Low-Pass is an electrical circuit that reduces or strengthens all frequencies starting from a specific frequency. frequency which Low-Pass operates is called the Corner Frequency. The elevation or lowering of the frequencies influenced by the Low-Pass is carried out using the Bass Regulator (Bass).
Parametric / Fully parametric parametric = parametrisable, adjustable Some circuits designated “parametric or fully-parametric EQs”. They have at least one regulator for each range (bass, mid-frequencies, treble) for the reinforcement or lowering of the frequency range, a second one for the point of application (Corner Frequency,...
This effect can only be counteracted by continuous correction input sensitivity.Electrical circuits were developed to avoid this dilemma, and these are called compressors or / and limiters. The difference between the compressor and the limiter is fluid. A limiter has an adjustable reference level. If the signal level remains below this, then nothing happens.
Insert (Send / Return) Insert = add (loop-in) Send = output (transmitter) Return = input (receiver) An “Insert Connection” means a connection combination that permits “looping-in” an additional device into the signal path (effect devices such as reverberation, echo, chorus etc.).
4.1 General points - amplifiers are designed as combo-amplifiers. This means that both functional units (speaker and amplifier) are housed in a single enclosure. They can also be used separately, however The electronics (head or amplifier) can be removed and mounted in a rack, for example.

The MUTE function can also be operated using a foot-switch. This makes the installed MUTE switch ineffective. The SINGLE Version only has a Volume Regulator. This is used to set the maximum volume. The DUO Version has an additional Volume Regulator for each of the two channels (adjusting the channel volume) and a Master Regulator for setting the overall volume.

The mains connection socket is on the back of the - amplifier, next to the cooling body The mains voltage fuse is installed between the mains switch and the cooling socket. Warning of electric power The setting of the mains voltage is marked on your unit. Check this before inserting the mains cable.

4.3 Connection diagramm back side This overview is intended to provide the experienced user with a simplified general view. More detail is available in the explanations. The arrows indicate the direction of the signals at the individual connections. If they point away from the specific connection, then it is a pure output.
5. Commissioning Take time with initial commissioning and read this chapter carefully. We have taken great care to make all the necessary details understandable even by the layman. However, if you still have any questions then please consult an experienced user or give us a call.

Play a couple of notes and slowly turn the gain regulator to the right until the green LED comes on and the yellow LED flickers (VU display). If the red LED on the VU display comes on, turn the gain regulator to the left until it goes out.

In order to test the function of the treble regulator, carry out the same procedure as with the bass regulator. Then return the bass and treble regulators to the mid position. For the mid regulation involves three regulators: This - frequency, level and Q (quality). The basics could already be seen in Chapter 2.
