4. CONTROL ELEMENTS

1 MIC INPUT (1 to 4)

Your is YdXipMXB/BFX4 low-noise microphone preamplifiers with optional phantom power, 50 dB of Gain and 115 dB of S/N ratio. You can connect almost any type of microphone. Dynamic microphones do not need phantom power. Use phantom power only with condenser microphones but make sure that the phantom power button is disengaged before connecting the microphone. Phantom power will not damage your dynamic microphones but it may damage tube or ribbon microphones so make sure to read the microphone instructions manual before engaging phantom power. Use switch (24) to activate/deactivatephantom power. These two 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.

NOTE: Never try to connect a line-level signal to the XLR MIC input when the phantom power is engaged or you may seriously damage your equipment.

2 STEREO LINE INPUTS (5 to 8)

These are channels 5/6, and 7/8. They are organised in stereo pair and provided with 1/4" TRS phone sockets. If you connect only the left jack, the input will operate in mono mode, that is the mono signal will appear on both input channels. You can use these inputs with a stereo keyboard, drum machine, etc.

3 GAIN

This control is provided with 2 different indication rings: one is for 1-4 channels, with a range of 0\~50dB when MIC is used and a range of +15\~-35dB when LINE is used, the other for 5-8 channels with a range of +20\~-20dB. For optimum operation, you shall set this control in a way that the PEAK LED will light up only occasionally in order to avoid distortion on the input channel.

4. CONTROL ELEMENTS

4 AUX SENDS

For AUX1(MON) jack, use this to connect the input of an external amplifier or active monitor speaker. For AUX2(FX) jack, use this to output the line level signal of the AUX2 post fader bus. You can use it to feed the inputs of a stereo multi-effects (you will need a Y-type cable).

5 AUX RETURNS

You can use these stereo 1/4" phone sockets to return the stereo signal of an effect unit to the Main Mix. Alternatively you can use them as an extra auxiliary input and using the AUX RETURN level control as volume control. The signal will be sent directly to MAIN MIX control.

6 CTRL ROOM OUTPUT

These 1/4" phone sockets will be used to send the signal to a pair of powered Studio Monitor speakers or to a second set of PA.

7 MAIN MIX OUTPUTS

This stereo output is controlled by the Main Mix Level on the Master section and will send the audio signal to an amplifier or to a pair of active speakers. The output level can be varied from -∞ to +10 dB.

8 CD/TAPE IN

Use the Tape input to connect a CD Player, Tape, DAT, iPOD or any other line-level source. You can send this signal either to CONTROL ROOM OUTPUT and/or to the MAIN MIX OUTPUT using the relative CD/TAPE TO select buttons.

9 CD/TAPE OUT

These RCA jacks will route the main mix signal into a tape or DAT recorder.

10 PHONES

This socket will be used to send the signal to a pair of headphones.

CHANNEL STRIP

11 LEVEL

This knob controls the channel's level from -∞ to +10 dB.

12 PEAK LED

This red LED will let you know about the status of the signals processed into your .DYNXeMIX8A(EX)phNX-or an instrument to your

MIX82(FX) and sing/play at normal volume. Set the level control of that channel so that the PEAK LED lights-up only occasionally. If this LED is always on, you are experiencing a lot of distortion and you should turn the GAIN control down or reduce the EQ boosting. If this led never lights up, turn the GAIN control up again.

4. CONTROL ELEMENTS

13 PAN/BAL

This is the PANORAMA control, or balance control. You can adjust the stereo image of the signal via this control. Keep this control in center position and your signal will be positioned in the middle of stage. Turn this control fully counter clockwise and the signal will be present only on the left speaker and vice-versa. Of course a large number of intermediate positions is available.

14 AUX

These two controls are used to adjust the level of the signal sent to AUX buses, and their adjustable range goes from -to+10dB. AUX1 is configured as PRE(MON)-FADER, so, generally, it can be used for monitor application. While AUX2 is configured as POST(FX)-FADER, therefore, most of the times, it will be used for effects and processors input, however, you can also changed it to PRE(MON)-FADER configuration according to the specific application. (For more detail, please see chapter 6.) In this typical compact unit, excluding sending out directly to the external effect or processor equipment, AUX SEND2 will also be sent to the internal onboard effect module.

3-BAND EQ

You have three EQ control for each mono and stereo input channel each providing +/-15 dB of boost and cut (MID is +/-12 dB). The signal will be unaffected when the controls are on center position. You may use an external equalizer to make up a mix properly but a master equalizer will not have effect on a single channel and you may overload the signal easily. Individual EQ will give you a much better control on single tracks.

15 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.

16 MID

This is a peaking filter and it will boost/cuts frequencies with their center at 2.5 kHz. This control will affect especially upper male and lower female vocal ranges and also the harmonics of most musical instruments.

4. CONTROL ELEMENTS

17 LOW

If you turn this control up, you will boost all frequencies below 80 Hz. You will give more punch to bass drums and bass guitar; and you will make the male vocalist more "macho". Turn it down and 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.

MASTER SECTION

18 MAIN MIX LEVEL

This knob controls the level of the signal sent to MAIN OUTPUTS and CD/TAPE OUT. Also AUX RETURNS and CD/TAPE IN signals will be sent to this control.

This knob controls the signal sent to CONTROL ROOM OUTPUT & PHONES OUTPUT.

20 CD/TAPE IN

This knob controls the signal sent from CD/TAPE IN.

21 OUTPUT LEVEL METERS

These consist of two column of 8 LEDs each ranging from -30 dB to +18 dB (CLIP). The O LED corresponds to a level output of 0 dBu. The CLIP LEDs come to life when the output reaches +18 dBu. Set the MAIN MIX level control so that the CLIP LEDs only flashes occasionally. In general, you get a good mix level when the Meter LEDs operate in the range 0 to +6. If you exceed +6, you will get distortion. If even -30 LEDs are sleeping your signal-to-noise ratio will suffer.

4. CONTROL ELEMENTS

22 AUX RETURNS

TO MAIN MIX, This control is used to control the volume of the processed signal sent to Main Mix bus, which can be varied from -∞ to +10 dB.

TO AUX1 MON, This control is used to control the volume of the processed signal sent to Monitor Mix, which can be varied from -∞ to +10 dB.

23 MAIN/CD/TAPE

If you push down the CD/TAPE TO CONTROL ROOM button, the CD/TAPE IN signal will be routed into the Control Room output and the level will be adjusted by the Control Room knob nearby the Main MIX LEVEL knob.

24 CD/TAPE TO MAIN MIX

If you push down the CD/TAPE TO MAIN MIX button, the CD/TAPE IN signal will be routed into the MAIN output and will be adjusted by the MAIN MIX LEVEL knob.

25 PHANTOM PWR Switch

This button will apply +48 Volt Phantom Power only to the 4 XLR MIC input sockets. When condenser microphones are not used, please make sure that the Phantom Power is disengaged.

26 PHANTOM LED

This LED indicates when the PHANTOM POWER is engaged.

27 POWER LED

This LED indicates when your LYNX-MIX82(FX) is switched on.

DSP SECTION(For LYNX-MIX82FX Model)

There is a powerful 24-bit/256 preset digital multi-effects included in your LYNX-MIX82FX. Effects include reverbs, chorus, flanger, delay and combinations of the above.

28 PRESETS

This knob will select one of the 16 Factory Presets.

29 VARIATIONS Control

For each of the 16 Factory Presets you can apply up to 16 variations, so in total your LYNX-MIX82FX offers 256 different presets. If you want to know which parameter is modified by this control, please look at the following chart.

4. CONTROL ELEMENTS

5. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your . LYNXeMIX8&FAdvise you to read carefully the

following section to be the real master of your own mix. Not paying attention enough 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 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-MIX82(FX) or the connected power amplifier at no more than 75%.
4. Now, set the CONTROL ROOM/PHONE level at no more than 50%.
5. Position HI, MID and LOW EQ controls on middle position.
6. Position panoramic (PAN/BAL) control on center position.
7. With a pair of headphones or studio monitor speakers connected apply a Line Level input signal so that the PEAK LED does not light up.
8. While speaking into the microphone (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 ideal dynamic range.
9. 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.

Audio Connections

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

6. APPENDIX

PREFADER AND POSTFADER CONSIDERATIONS

Interesting consideration! Where are the faders in your ?? LYNX-MIX82(FX) Actually a fader is usually regarded as a slider, that is a linear potentiometer. All potentiometers in your LYNX-MIX82(FX) be but we keep the pre-fader/post-fader description that is quite industry standard and easily understandable. When your LYNX-MIX82(FX) leaves the Alto Factory, the AUX bus of all input channels is wired post-fader. In this way, the Aux bus can be used for the internal or external multi-effect. If you want to use the LYNX-MIX82(FX) Aux bus for powered stage monitors, you should disconnect the above-indicated POST route track and solder the PRE route track like in this drawing. In this way, the signal is routed to the AUX SENDS output before the Channel Level control.
