General Precautions

• Damage: To prevent damage to the controls and cosmetics avoid placing heavy objects on the control surface, scratching the surface with sharp objects, or rough handling and vibration.
• Environment: Protect from excessive dirt, dust, heat and vibration when operating and storing. Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and moisture. If the console becomes wet, switch off and remove mains power immediately. Allow to dry out thoroughly before using again.
• Cleaning: Avoid the use of chemicals, abrasives or solvents. The control panel is best cleaned with a soft brush and dry lint-free cloth. The faders, switches and potentiometers are lubricated for life. The use of electrical lubricants on these parts is not recommended. The fader and potentiometer knobs may be removed for cleaning with a warm soapy solution. Rinse and allow to dry fully before refitting them.
• Lifting: To avoid injury to yourself or damage to the equipment take care when lifting, moving or carrying the console.
• Transporting: The console may be transported as a free-standing unit or mounted in a purpose-built flight case. We recommend that the console is surrounded by shock-absorbent foam to protect it from damage during transit. Always use adequate packing if you need to ship the unit. Protect the controls to avoid damage when moving the console.
• Hearing: To avoid damage to your hearing do not operate any sound system at excessively high volume. This also applies to any close-to-ear monitoring such as headphone and IEM transducers. Continued exposure to high volume sound can cause frequency-selective or wide range hearing loss.

Important Safety instructions

PRECAUTIONS: Please read the following instructions before proceeding.

WARNINGS
Beware of electric shock!
Do not open!

• Read instructions: Read and retain these safety and operating instructions for future reference.

• Adhere to all warnings printed here and on the console. Follow the operating instructions printed in this User Guide.

• Do not remove cover: Operate the console with its underside cover correctly fitted. Disconnect mains power by unplugging the power cord if the cover needs to be removed for setting internal options. Refer this work to competent technical personnel.

• Power Sources: Connect the console to a mains power outlet only of the type described in this User Guide and marked on the rear panel. Use the power cord with sealed mains plug appropriate for your local mains supply as provided with the console. If the provided plug does not fit into your outlet consult your service agent for assistance.

• Power cord routing: Route the power cord so that it is not likely to be walked on, stretched or pinched by items placed upon or against it.

• Grounding: Do not defeat the grounding and polarization means of the power cord plug. Do not remove or tamper with the ground connection in the power cord .
  Warning: Thi s equipment must be earthed.

• Water and moisture: Do not expose the device to rain or dampness, use it in damp or wet conditions, or place containers on it containing liquids which might spill into any openings.

• Ventilation: Do not obstruct the rear and top ventilation openings, or position the console where the airflow is impeded. If the console is to be operated in a flight case, plinth or other furniture, ensure that it is constructed to allow adequate ventilation.

• Heat and vibration: Do not locate the console in a place subject to excessive heat or direct sunlight to prevent fire hazard. Locate the console away from any equipment generating heat and excessive vibration.

• Servicing: Switch off the equipment and unplug the power cord immediately if it is exposed to moisture, spilled liquid, objects fallen into the openings, the power cord or plug become damaged, during lightening storms, or if smoke, odour or noise is noticed. Refer servicing to qualified technical personnel only.

• Installation: Install the console in accordance with the instructions printed in this User Guide.

• Do not connect the output of power amplifiers directly to the console. Use audio connectors and plugs only for their intended purpose.

Introduction

• Welcome the latest generation of the popular mixing consoles. We have tried to keep this user guide brief and to the point. Please read it fully before starting. Included is information on installing, connecting and operating the console, panel drawings, system block diagram and technical specification.
• For further information on the basic principles of audio system engineering, please refer to one of the specialist publications and resources available from bookshops, audio equipment dealers and the internet.
• Whilst we believe the information in this guide to be reliable we do not assume responsibility for inaccuracies. We also reserve the right to make changes in the interest of further product development.

Introducing the mixer

This is a an analogue mixing console for professional audio applications. Whether out on the road touring, in a small meeting room, a bar or earning it’s keep in rental stock, the mixer provides the perfect solution to provide simple and convenient connections, and quickly form a sound amplifying system. Engineered to the same exacting standards as our top of the range consoles it ensures the highest reliability and finest sonic performance.

The MONO input channel

MIC/LINE IN XLRAND TRS JACKS
These jacks are used for microphone or line level signals. If you use XLR jack, it can give a massive headroom for the channel’s pre-amp with +34dBu maximum input power. Two inputs are both balanced, but they can handle unbalanced signals when required. MIC XLR jack feeds microphones requiring phantom power such as condensers via 6k8 ohm resistors to provide +48V DC powerto pins 2 and 3.

Warning: When +48V phantom power is selected, do not connect the unbalanced sources or cables to the XLR input. To avoid loud clicking sound, always turn the channel off when switching on or off the +48V power, and when plugging or unplugging cables.

• GAIN
  Adjusts the input sensitivity to match the connected source to the internal 0dBu operating level of the channel. It provides a variable range of 40dB, from +Oto +40dB gain (MIC), or from -20 to +20dB (LINE, PADDED MIC). In co- ordination with the monitor system and the main level meters, adjust the gain knob for a metering average of “OR for the channel with loudest moment lighting “+6”.
  Important instructions for the channel’s level setting: Use PFL to set the gain control and to determine the correct level of the signals going through each channel. The main LR meters provide high-definition display for the channel’s signal level. Use the fader to balance each signal in the mix. To ensure optimum gain structure, we do not recommend the way of mixing by setting the fader to II O II position and using gain control to mix.

• EQ
  A responsive 3-band EQ (equalizer) provides independent controls for 3 frequency bands.
  The HIGH and LOW bands are shelving filters, which affect respectively the high frequencies above 12 KHz and the low frequencies below 80 Hz. The MID band is a bell-shaped peak/dip filter, which affect the frequencies centering near 2.5KHz.
  All frequency bands can increase or decrease up to 15dB, and have a center detent position of 0dB. The overlapping frequency range allows you to deal with the challenging sound source problems with ease when using frequency band combinations.

• AUX send
  These rotary controls adjust how much channel signal will be mixed to the aux out.

• FX send
  When you want to get echo effect of each channel, you can adjust the level of installed echo by this.

• PAN
  This has a function which distributes the signal level between left and right channels to
  make a stereo sound effect.

• PEAK!
  This is the lamp which indicates the input signal level of this appliance (regardless of output) when GAIN volume level is adjusted.’

• FADER
  These are used for adjusting the volume of signal sources, which are connected to the relevant channels.

• PFL
  You can monitor the signal of the only channel on which PFL switch is turned “ON” through the headphone (In this time, the other channels Are automatically out off.)
