Control Elements

The following features will be applied to 12 channels,14 channels,16 channels and 24 channels. In case where different features need to be described for each other, the unit 12 channels and 14 channels will be descried first, followed by the unit 16 channels and 24 channels feature in brackets.

1. MIC INPUT JACKS ( CH 1 to 7/8 for 12 channels or CH 1 to 9/10 for 14 channels or CH 1 to 11/12 for 16 channels or CH 1 to 19/20 for 24 channels)

These are balanced XLR-type microphone input jacks

2. LINE INPUT JACKS ( CH 1 to 4 for 12 channels or CH 1 to 6 for 14 channels or CH 1 to 8 for 16 channels or CH 1 to 16 for 24 channels )

These are balanced TRS phone-jack line inputs. You can connect either balanced or unbalanced phone plugs to these jacks.

3. LINE INPUT JACKS ( CH 5/6 to 7/8 for 12 channels or CH 7/8 to 9/10 for 14 channels or CH 9/10 to 11/12 for 16 channels or CH 17/18 to 19/20 for 24 channels )

They are organized in stereo pair and provided with 1/4" TRS sockets. It is used to connect the stereo device, plug both the left input and the right input. Using the left input if connect a mono input signal to the stereo channel, the output signal will appear on both sides.

4. LOW CUT

By pressing this button you will activate a 75Hz low frequency filter with a slope of 18dB per octave. You can use this facility to reduce the hum noise infected by the mains power supply, or the stage rumble while using a microphone.

5. RCA INPUT JACKS ( CH 9/10 to 11/12 for 12 channels or 11/12 to 13/14 for 14 channels or CH 13/14 to 15/16 for 16 channels or CH 21/22 to 23/24 for 24 channels)

They are organized in stereo pair and provided with RCA sockets. It is used to connect the stereo device, plug both the left input and the right input.

6. HI-Z

To change to a high impedance input, push the appropriate hi-z switch.

7. GAIN CONTROL

Adjusts the input signal level. To achieve the best balance between S / N and dynamic range,

adjust the level so that the peak LED indicator lights occasionally only on the highest input transients. For each channel the MIC input adjustment range of the Gain is 0 to 50dB and the sensitivity of line input is +20 to -30dB.

8. COMP CONTROL

Adjust the amount of compression applied to the channel. Turn the knob to the right to increase the compression ration and the output gain will automatically adjusted. The result is smoother, more even dynamics because louder signals are attenuated which the overall level is boosted.

9. LINE/USB

By pressing this button, it will switch to the USB mode, then the USB signal can be sent to this

channel; by releasing this button, the LINE IN inputs signal will send to the line input channels.

10. LINE/USB PLAYER

11. EQUALISER CONTROLS

There are 3-band EQ with sweepable MID on all mono input

channel 1-4/1-6/1-8/1-16: HI, MID and LOW band. There are

4-band fixed frequency EQ on the stereo channel

5-12/7-14/9-16/17-24: HI, HI- MID, MID-LOW and LOW band. All

bands provide up to 15 dB of boost or cut.

--HI

If you turn this control up, you will boost all the frequencies above 12 kHz (shelving filter). You will add transparency to vocals and guitar and also make cymbals crispier. Turn the control down to cut all frequencies above 12 kHz In such way, you can reduce sibilances of human voice or reduce the hiss of a Tape player.

--MID

This is a peaking filter and it will boost/cut frequencies from 100 Hz to 8 kHz depending on the position of the MID freq control. This control will affect especially upper male and lower female vocal ranges and also the harmonics of most musical instruments.

--HI-MID

This control gives you up to 15 dB boost or cut at 3 kHz. It is useful for controlling voice. It can accurately polish your performance via adjusting this knob.

--MID-LOW

This control gives you up to 15 dB boost or cut at 500 Hz.

--LOW

If you turn this control up, you will boost all frequencies below 80 Hz. You will give more punch to bass drum and bass guitar and make the vocalist more "macho". Turn it down, you will cut all the frequencies below 80 Hz. In this way, you can avoid low frequency vibrations and resonance thus preserving the life of your woofers.

12. EQ SWITCH

This switch allows the user to use the EQ Section in signal path. Of course it can be used to make A/B comparisons between equalized signal and not equalized signal. It also can be used to apply equalization at a certain point of the show, excluding it when it's not necessary.

Ok, you have got to this point and you are now in the position to successfully operate your 12 / 14 / 16 / 24 Channel Mixing Console. However, we advise you to read carefully the following

section to be the real master of your own mixer. Not paying enough attention 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 these procedures for every single channel:

• Before connecting MICs or instruments, make sure that the power of all your systems

components including the mixer is turned off. Also, make sure that all input and output controls of your mixer are turned down. This will avoid damage to your speakers and avoid excessive noise.

• Properly connect all external devices such as MICs, power amplifiers, speakers, effect processor

etc.

• Now, turn on the power of any peripheral devices, then power up the mixer. Note: the power amplifier or powered monitors shall be turned on after the mixer and turned off

before the mixer.

• Set the output level of your mixer or the connected power amplifier at no more than 75%.

• Set the CONTROL ROOM/PHONE level at no more than 50%.

• Position HI, MID and LOW EQ controls on middle position.

• Position panoramic (PAN/BAL) control on center position.

• While speaking into the MIC (or playing the instrument ), adjust the channel Level control so

that the PEAK LED will blink occasionally, in this way you will maintain good headroom and idea dynamic range.

• You can shape the tone of each channel by adjusting the equalizer controls as desired.

• Now repeat the same sequence for all input channels. The main LED could move up into the red section, in this case yo can adjust the overall output level through the MAIN MIX control.

Some Final Tips on Wiring Configuration

You can connect unbalanced equipment to balanced inputs and outputs. Simply follow these schematics.
