4. CONTROL ELEMENTS

1 MONO MIC/LINE Channels

Your LYNX-MIX 124UM is equipped with 4 low-noise microphone preamplifier with optional phantom power, 50 dB of Gain and over 115 dB of S/N ratio. You can connect almost any type of microphone. Dynamic microphones do not need phantom power. Use phantom power for condenser microphones only, but make sure that the phantom power button is disengaged before connecting the microphone. Phantom power will not damage your dynamic balanced microphones, so make sure to read the MIC instructions manual before engaging phantom power. Use switch (48) to activate/deactivate phantom power. These channels are also equipped with 1/4" TRS balanced/unbalanced LINE-IN plugs to connect line-level instruments such as keyboards, drum machines and effect devices.

2 STEREO INPUTS

These are channels 5 through 12. They are organised in stereo pair and provided with XLR sockets (channels 5/6) and 1/4" TRS phone jacks. If you connect the left jack only, the input will operate in mono mode, so the left input signal will appear on both input channels. You can use these inputs with a stereo keyboard, drum machine, etc.

3 MONO Channel INSERT

This is where you connect external sound processors such as compressorlimiter, equalizers, etc.. The insert point is available on the first 4 mono MIC channels only.

4 TRIM

The TRIM control is applied in the mono MIC and stereo input channels. It provides with 2 different indications: One is for the MIC and the other for LINE levels. When you use a microphone, you shall read the MIC ring (0~50 for mono MIC input, 0~40 for stereo channels); when you use a line level instrument, you shall read the LINE ring (+15~-35 dB for mono MIC input, +20~ 20 dB for stereo channels). For optimum operation, you shall set this

control in a way that the PEAK LED (17) blinks only occasionally in order to avoid input channel distortion.

SPOTLIGHT

4. CONTROL ELEMENTS

5 LINE GAIN

When you use a line level instrument, you shall read the ring (-20~+20 dB). For optimum operation, you shall set this control in a way that the PEAK LED (17) signal peaks only, thus avoiding input channel distortion.

6 LEVEL SET LED

This LED will help you to easily detect the input level, thus making much faster the research of distorted signals.

7 LOW-CUT Button

By pressing this button, you will activate

a 75 Hz low frequency filter with a slope of 18 dB 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.

8 LINE/MP3 Button

By pressing this button, it will switch to the MP3 mode, then the Mp3 signal can be sent to this channel or the Main Mix channel; by releasing this button, the LINE IN inputs signal will send to the line input channels.

9 LINE/USB Button

By pressing this button, it will switch to the USB mode, then the USB signal can be sent to this channel or the Main Mix channel; by releasing this button, the LINE IN inputs signal will send to the line input channels.

EQUALISER

There are 3-band EQ with sweepable MID on all mono input channel1-4: HI, MID and LOW band. There are 4-band fixed frequency EQ on the stereo channel 5-12: HI, HI-MID, MID-LOW and LOW band. All bands provide up to 15 dB of boost or cut.

10 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 human voice sibilances or reduce a tape player hiss.

SPOTLIGHT

4. CONTROL ELEMENTS

11 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. Setting the frequency control on lower frequencies, this control will affect the range of fundamental frequencies of most instruments, including human voices, as well as some harmonics when set to higher frequencies.

12 HI-MID

This control gives you up to 15 dB boost or cut at 3 kHz. It is useful for controlling

voice. making the performance brighter.

13 MID-LOW

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

14 LOW

Turning this control up, all the frequencies below 80 Hz will be boosted. You will give more punch to bass drum and bass guitar and make the vocalist more "macho". Turning it down, you will cut all the frequencies below

80Hz. In this way, you can avoid low-frequency vibrations and resonance thus preserving the life of your woofers.

15 AUX SENDS Level Control

These four controls are used to adjust the level of the respective signal sent to AUX bus, AUX1 and AUX2 can be switched to PRE/POST-FADER via the PRE/POST button, so, generally, they're used PRE-FADER for monitor application and POST-FADER for effect units. AUX3 and AUX4 are configured as POST-Faders. Generally speaking, the users of this unit will use the onboard DSP effect module setting AUX send 4. Alternatively, it's possible to connect an external effect unit input to EFX2 SEND connector.

16 PAN/BAL Control

5. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your LYNX-MIX 124UM. However, we advise you to read the following section carefully to be the real master of your own mix. Not paying enough attention to the input signal level, 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 this procedure for every single channel:

1. Turn down all Input and output gain controls.

2. Connect phantom powered microphones before switching on the +48 Volt phantom power switch.

3. Set the output level of your LYNX-MIX 124UM mixer as "0", and the connected power amplifier at no more than 75%.

4. Now, set the CONTROL ROOM/PHONES level at no more than 50%. In this way, you will be able to hear later what you are doing connecting a pair of headphones or a pair of powered studio monitor speakers.

5. Position EQ controls on middle position.

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

7. With a pair of headphone or studio monitor speakers are connected, apply a Line

Level input signal so that the PEAK LED does not light up.

8. Increase the input gain properly for maintaining the good headroom and ideal dynamic range.

9. Depending on the actual application, turn slowly the input and output level controls for obtaining the maximum gain before distortion.

10. Now repeat the same sequence for all input channels. The main LED meter could move up into the red section. In this case you can adjust the overall output level through the main mix control.
