FUNCTIONS

MIC/LINE IN XLR AND TRS JACKS
These jacks are used for microphone or line leveI signals. lf you use XLR jack, it can give a massive headroom for the channel’s preamp with +34dBu maximum input power. The two inputs are both balanced, but they can handle unbalanced signals when required.
The MIC XLR jacks are used for microphones requiring + 48V DC phantom power to pins 2 and 3 (such as the condensers 6,8 KOhm).

WARNING:
When +48V phantom power is selected, do not connect 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: It adjusts the gain level of each channel’s input signal.
  We suggest to set the related vu-meter on average level “0”, paying attention that the PEAK led doesn’t remain steady on. lmportant instructions far 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, through headphone monitoring. The main LR meters provi de highdefinition display far the channel’s signal level. Once set the gain level, use the specific faders to balance each signal in the mixing and adjust the channels’ volume.
  

• EQ: The 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 peak/dip filter, which affects the frequencies centering near 2.5KHz. AII frequency bands can increase or decrease up to 15dB, and have a center detent position of 0 dB.
  
  

• AUX SEND : These rotary controls adjust how much channel signal will be mixed to the AUX SEND socket.

• 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 led which indicates the input signal level of an appliance when GAIN volume level is adjusted.

• FADER: These are used far 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 case, the other channels are automatically out off.)

EFFECT CHANNEL

• EFFECT SEND SIGNAL MAIN
  CONTROL (FX): Adjusts the total volume of the effect signal sent to the console’s internal effect processor and output.

• DELAY: Adjusts the length of the time span between each echo, to simulate the reverb effect.

• REPEAT: Adjusts the times and depth of the echoes of the effector.

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

• PFL: When you want to monitor echo sound & external effect sound, you can adjust this control through the headphone.

• EFFECT FADE: These are used tor adjusting the volume of signal sources, which are connected to the relevant channels.

AUX / TAPE / PHONE

• AUX/MST
  Adjusts the volume from the output jack of the AUX SEND channel in order to match the external devices.

• AFL
  When you want to monitor echo sound & external effect sound, you can adjust this control through the headphone.

• TAPE INPUT
  Adjusts the volume of the signal (CD or line external device) to the main channel L/R .

• PHONES LEVEL
  Adjusts the volume of the monitor headphone. Use a proper volume to avoid the damage to your hearing.
  WARNING:
  When selecting phantom power, do not connect unbalanced sources or cables to the XLR input. To avoid big clicking sound, mute the channel when turning on or off the +48V power.

• PFL/AFL
  If this led is on it indicates that the headphone monitoring function of the channel is activated. The main level meters show the signal level of the monitor channel.
  • FADER:
  Adjusts the output level of the main mix, providing a normal boost from 0dB to +10d B.

MAIN MIXER

• +48V PHANOTM SWITCH
  +48V DC switch supplies power to the channel’s XLR input, providing power for the microphone requiring phantom power or DI-BOX. The power currents are restrictive, providing power to the XLR socket’s pin 2 and pin 3 of the mono input channel via 6k8 ohm resistors.

• MAIN LEVEL METERS
  In normal conditions, it shows the output level of the main mix signals. When any channel’s PFL or AFL button is pressed down, it switches to show the signal leveI of that channel.

• POWER
  Power indicator. lt lights to show the mixer is powered.

MAIN OUTPUT SECTIONS

• LOUT/R OUT
  The console’s main mix output is XLR & JACK. L and R output usually sends signals to the indoor PA (public address) system for live sound mixing, or to a 2-track recorder for studio mixing.

• CTRL ROOM OUT
  Unbalanced TRS output. These jacks are used for sending signals to speakers or other monitor systems.

• PHONES
  Unbalanced TRS 6,3mm jack. You can insert a headset, listening on a local monitor output. We recommend that you use closed headphones of 30 to 600 Ohm impedance. Please note: Adjust the volume to avoid hearing damage

• AUX SEND OUT
  Unbalanced TRS jack output for AUX SEND signals, which is for sending to monitor, effect devices such as echo and delay, and special mixing requirements.

• EFFECT SEND
  These are to be connected with external digital reverb & effect equipment.

• EFFECT RETURN
  These are to be connected with external digitai reverb & effect equipment.

• TAPE IN/ OUT
  RCA input and output to connect common recording and playing equipment, such as CD, MiniDisc, computer etc..

BLUETOOTH AND MP3 PLAYER

• Main menu key.

• Press to enter the multi-level settingsBackward/ previous track

• Fast forward/ next track

• PLAY, PAUSE, and ENTER key.

• MP3 LEVEL
  Adjusts the main volume of the playing MP3 player.

• MP3 PLAYER CHANNELS
  When the key is up, the MP3 playing signal will go directly to the main channel L/R outputs.
  When it’s down, the signal is sent to the CH 15/16 channels (which cannot be occupied).
  Thus, the output signal from the MP3 player can go into the CH 15/16 channels, where it is possible to add effects.

REAR PANEL FUNCTION

The picture shows the power socket and the on/off switch on the mixer’s rear panel.
Use only the original adaptor and respect the required tension indicated on the adaptor.
After you plug the power adaptor properly to the power input socket of this console, you should screw the nut going with the plug tightly and firmly.
