Frequently Asked Questions - LYNX-MIX124UM ALTO

How do I connect a microphone?

Use an XLR cable to connect a dynamic or condenser microphone to the MIC input. For condenser mics, ensure +48V phantom power is activated via the rear panel switch. Keep all faders down when connecting.

Can I use this mixer for recording via USB?

Yes. The USB port allows bidirectional audio with a PC. Use the USB RECORD switch to select SUB1/2 or MAIN MIX as the recording source, and USB PLAYBACK to route PC audio to CH11/12 or MAIN MIX.

How do I apply effects to a specific channel?

Set the channel's AUX4 send level to the desired amount. Make sure the DSP effect is active (DSP MUTE switch off) and select a preset and variation using the PRESETS and VARIATIONS knobs. The effect returns via the internal DFX return.

Why is the PEAK LED lighting up?

The PEAK LED indicates the signal is nearing distortion. Reduce the TRIM or GAIN control on that channel, or lower the EQ boosts. If the master meter clips, reduce the MAIN MIX fader.

How do I connect external effects?

Use the INSERT jacks on mono channels or the MAIN INSERT for the whole mix. Alternatively, use AUX SEND outputs to feed external processors and return via AUX RETURN inputs. Adjust return levels with the STEREO AUX RETURNS knobs.

What type of USB flash drive is compatible?

The MP3 player supports USB drives formatted as FAT16 or FAT32. Only MP3 files are playable. The drive can have up to 7 folder levels. Insert the drive, and the display will show 'Searching'.

How do I set up a monitor mix?

For monitor sends, use AUX1 or AUX2 in PRE mode (press the PRE/POST button) so the level is independent of the channel fader. Connect the AUX SEND output to a powered monitor or amp. Adjust the master AUX sends.

What is the difference between PFL and AFL?

PFL (Pre-Fader Listen) lets you hear the channel signal before the fader and EQ, regardless of the fader position. AFL (After-Fader Listen) listens after the fader. Use the SOLO MODE button to toggle between them.

My mixer has no power. What should I check?

Check the power cord connection and the mains voltage setting. Ensure the POWER switch is on. Verify the fuse; if blown, replace with the same type: T1.25 AL. If problems persist, consult qualified service personnel.

Can I use unbalanced cables with balanced inputs?

Yes. For XLR inputs, connect pin 1 to 3 for unbalanced use. For TRS jacks, use a TS plug (tip/sleeve) – the ring is connected to ground automatically. Balanced operation is recommended for long cable runs to reduce noise.

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 compressor-limiter, 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.

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.

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

Abbreviation of PANORAMA control for mono channels, allowing to set the stereo signal front. Keeping this control in central position, the signal will be equal in both Left and Right speakers. Stereo channels have BALANCE control, similar to your hi-fi set control.

17 PEAK LED

Inside your LYNX-MIX 124UM mixer, the audio signal is treated in several different stages and then sent to the PEAK LED. When the LED is red illuminated, it warns you that you are reaching signal saturation and possible distortion. In order to avoid distortion you should reduce the GAIN, EQ, or LEVEL settings.

18 MUTE Button & LED

Each channel is equipped with a MUTE button. Pressing this button is equal to turning the fader down, which can mute the corresponding channel output except for the channel INSERT send and SOLO (in PFL mode). And the MUTE LED will illuminate.

19 ASSIGNMENT Controls

Each channel provides four push-buttons: SUB1-2, SUB3-4, MAIN L-R and SOLO. Pressing the SOLO button, the corresponding SOLO LED will illuminate and the SOLO signal will replace other signals send to the Headphone/Control Room and Meters. Usually use the SOLO function in live work to preview channels before they are let into the mix. It is useful to set an instrument's input level and EQ, and you can also solo any channel that you want to. The SOLO switch never affects any mix other than the Control Room. The other three buttons are signal assignment switches. Pressing the SUB1-2 will assign the channel signal to Subgroup1/2, using the PAN knob you can adjust the amount of channel signal sent to the SUB1 versus SUB2, completely turning the Pan to left, the signal will be addressed to Subgroup1 only and vice-versa. In the same way, pressing the SUB3-4 or MAIN L/R will assign the channel signal to Subgroup3/4 or MAIN MIX L/R, and this setting too will be affected by PAN.

20 FADER

This fader will adjust the overall level of this channel and set the amount of signal send to SUB1-2, SUB3-4, and MAIN L-R outputs.

21 Control Room Source

You can choose to monitor any combination of MAIN MIX, SUB1-2, SUB 3-4 and 2TK IN via these Matrix switches. Engaging these switches, the stereo signals will be delivered to the Phones, Control Room and Meters display.

※NOTE: When any SOLO switch was engaged, the SOLO signal will replace other signals, and that signal will be present to Control Room, Phones, and Meters.

22 PHONES/CTRL ROOM Controls

Rotate these knobs to independently adjust the stereo level of CTRL ROOM and PHONES-these levels should adjusted from -∞ to MAX.

4. CONTROL ELEMENTS

23 Master AUX SENDS Controls

These four controls are used to determine the master AUX SEND levels, which can be varied from -∞ to +15 dB. Connecting to your mixer an external effect units with no input gain control, you can get a further +15 dB gain available from these Aux Send outputs. In the same way, AUX4 Master control will provide the needed level adjustment for the internal effect unit.

24 SOLO Button

The function of these SOLO buttons is similar to channel SOLO buttons. Pressing any SOLO button, the corresponding AUX send will be routed to the Ctrl Room/Phones outputs and Meters display.

25 Master STEREO AUX RETURNS Controls

These four controls set the level of effects received by stereo AUX RETURN connectors, which can be varied from - to +15 dB. They are used to provide the further gain for low level effects.

26 TO AUX SEND1/2

Both these rotary knobs assign the AUX RETURN signals to their respective AUX SEND outputs: The "TO AUX SEND1" assign the signal from AUX RETURN1 to AUX SEND1 bus, and "TO AUX SEND2" assign the signal from AUX RETURN2 to AUX SEND2 bus. The adjustable range goes from -do +15 dB.

27 MAIN MIX & CTRL/R Button

AUX RETURN3 is equipped with the Main Mix & Ctrl/R button. Release the button to send the stereo signal from AUX RETURN3 to MAIN MIX buses; Engage the button, then the stereo signal will be sent to CTRL/R output.

28 SUB1-2/SUB3-4/MAIN MIX Buttons

These three buttons are configured for AUX RETURN4, they can be regarded as the signal assignment switches. When engaging the SUB1-2, the stereo signal from AUX RETURN4 will be assigned to Subgroup1/2; in the same way, pressing SUB3-4 the signal will be assigned to Subgroup3/4, and pressing MAIN MIX it will be assigned to MAIN MIX buses.

29 AUX RETURNS SOLO Button

The function of AUX RETURN SOLO is like the channel SOLO button. Engaging this switch signal from AUX RETURN (1-4) will be sent to CTRL OUT, PHONES outputs and Meters display. Pressing this button, the LED next to the button will light. This feature is affected by SOLO mode button (n.35).

30 SUBGROUPS ASSIGN TO MAIN MIX

Through these switches, you can operate the subgroup faders as a master controls assigning the subgroup signals to MAIN MIX. Engage the LEFT switch to send the corresponding subgroup signal to MAIN MIX L, and the RIGHT switch for MAIN MIX R. When engaging the both switches, the signal will be sent to L/R of MAIN MIX.

31 SUBGROUPS Fader

These faders are used to control the levels of the signal send to the SUB-GROUPS OUT, the adjustable range goes from - to +10 dB. Any channel that is assigned to the subgroups, not muted and not turned down will be assigned to the SUB OUTS.

This fader sets the amount of signal send either to the Main Mix Output and to the Tape Output.

33 LED Meter

The stereo 12-segment LED Meter shows the level of signal send to Ctrl Room and Phones outputs.

34 2TK TO MIX Button

Engaging this switch allows you to combine the 2-Track output with the Main Mix. In other words, feeds the 2-Track In signals into Main L/R output. after the Level control, otherwise, release the button will output the soloed signal before the Level control.

※NOTE: The SOLO function will never affect sound output to main recording output, and also can't be affected by channel's MUTE switch.

4. CONTROL ELEMENTS

35 SOLO MODE Button

This button provides two modes: up for PFL (Pre-Fader-Listen) mode, down for AFL (After-Fader-Listen) mode.

36 EQ Switch

Engage this button to include the stereo graphic EQ in ST OUT output circuit. It can be used to modify the overall sound character of your mix. If you release the button, the stereo graphic EQ will be bypassed.

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 "O", 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.
