Frequently Asked Questions - Live 1202 ALTO

How to connect a microphone to the Live 1202 console?

Connect the microphone to an XLR input (channels 1 to 6). Make sure the channel is set to mic mode (Line/Mic switch). Enable 48V phantom power if needed via the +48V switch on the rear panel. Adjust the gain with the Gain knob to achieve an optimal level without clipping.

How to activate phantom power (48V)?

Phantom power is activated globally via a +48V switch on the rear panel of the console. Press this switch to power the XLR inputs (channels 1 to 6). Check that your microphones are compatible with 48V before activation.

How to adjust the equalizer of a channel?

Each mono channel has a 3-band equalizer with knobs for treble, mid, and bass. Turn the knobs clockwise to boost the corresponding frequency, counterclockwise to cut. The zero point (12 o'clock position) corresponds to a flat response.

How to use the auxiliary sends (Aux)?

The Live 1202 has two auxiliary sends (Aux 1 and Aux 2). Each channel has an Aux knob to adjust the level sent to the corresponding Aux output. Use the Aux outputs (6.35mm jack) on the rear panel to connect stage monitors or effects processors.

What to do if no sound comes out of the console?

First check that the console is powered on (LED Power lit). Make sure channels are not Muted and volume faders are up. Check the master level and headphone output. Verify cables and speakers. If the problem persists, try a different input.

How to connect the console to powered speakers?

Use the main outputs Main Out (XLR or 6.35mm jack). Connect them to the inputs of your powered speakers, preferably with balanced cables. Set the console's master level then adjust the volume on the speakers. Avoid excessively high levels to prevent distortion.

How to record the mix from the Live 1202?

Use the Record Out (RCA) or the main outputs. Connect a cable to the input of your audio interface or recorder. You can also use the headphone jack as a line output with adjustable level. Set the master volume to obtain a suitable recording level.

How to avoid feedback?

Place microphones behind speakers. Reduce gain on microphone channels and cut ringing frequencies with the equalizer. Use auxiliary sends for monitors with caution. Avoid pointing microphones toward speakers. Enable a low-cut filter if available.

How to clean the mixing console?

Unplug the device before any cleaning. Use a soft, slightly damp cloth (not wet) to wipe surfaces. Never use abrasive products, alcohol, or solvents. Avoid liquid entering connectors or slots. Dry with a dry cloth.

What to do in case of hum or parasitic noise?

Check that all cables are in good condition and properly connected. Use balanced cables for long distances. Keep audio cables away from power cables. Ensure the console is properly grounded. If hum persists, try disconnecting sources one by one to identify the source.

Features

Top Panel

Note: The channels have essentially the same controls with some minor variations between Channels 1-4, 5-10, and 11-12. The three different channel types are shown here.

1. Mic Input: Connect a microphone or line-level device to these inputs with an XLR cable.
2. Line Input: Connect line-level devices to these inputs with 1/4" cables.
3. Insert: Use a standard 1/4" TRS cable to connect an external processor (such as a compressor, limiter, external EQ unit, etc.) to this jack. The signal will be taken after the channel's gain control and returned before the channel's EQ controls. The tip of the TRS connection is the send, and the ring is the return.
4. Gain: Adjusts the channel audio level (pre-fader and pre-EQ gain). Adjust this so that the Signal LED lights up.
5. Peak LED: The LED will flash if the signal is clipping. If this happens, decrease the setting of the Gain knob.
6. Low Cut Filter: When this button is depressed, that channel's audio will be sent through a 75 Hz low-frequency filter with a slope of 18 dB per octave. This is useful for reducing low-frequency noise when using microphones.
7. Compressor: Adjusts the amount of compression on the channel, applied by the mixer's built-in compressor. The LED next to the knob will light up when the compressor is on.
8. Hi EQ: Adjusts the high (treble) frequencies of the channel.
9. Mid EQ: Adjusts the mid-range frequencies of the channel.
10. Low EQ: Adjusts the low (bass) frequencies of the channel.
11. Monitor Knob: Adjusts the pre-fader level of the signal sent from that channel to the Monitor Mix, whose level is controlled by the Monitor Fader.
12. DFX Knob: Adjusts the post-fader level of the signal sent to the mixer's effects processor, whose level is controlled by the DFX Return Fader (DFX Rtn).
13. Channel Pan / Balance: If this knob is labeled Pan, it adjusts the (mono) channel's position in the stereo field. If the knob is labeled Bal, it adjusts the balance between the left and right channels of that stereo signal.
14. Channel Mute: Press this button to mute/unmute the channel. The LED next to the button will light up when the channel is muted.
15. Channel Fader: Adjusts the audio level on the channel.
16. Signal LED (Sig): Indicates that the channel's incoming audio signal is within an optimal range.

1. Aux Send: Use 1/4" TRS cables to connect these outputs to the inputs of an external amplifier or active monitor. Use the Monitor Knob (Mon) on each channel to control the level of the signal sent to Aux Send 1. This is useful for creating a custom monitor mix for onstage musicians.
2. Aux Return (Aux Rtn): Connect the outputs of an external device to these inputs with 1/4" mono cables. If your source is mono, plug it into the left jack and it will be heard on both the left and right sides.
3. Aux Return Fader (Aux Rtn): Controls the audio level sent into the Aux Return (Aux Rtn) inputs.
4. Graphic Equalizer: When the EQ On/Off switch is on (depressed), you can use these controls to adjust the equalization of the main mix.
5. EQ On/Off: Enables or disables the Graphic Equalizer.
6. Main Out / Monitor Out: When this button is raised, the Graphic Equalizer will affect the signal sent to the Main Mix Outputs. When this button is depressed, the Graphic Equalizer will affect the signal sent to the Aux 1 (Mon) Output.
7. Effect Selector: This knob determines what effect the mixer's internal effects processor will apply to the various channels. Turn the knob to change the effect number, and push the knob to select it. The display next to the DFX Mute button will show the preset number. Each channel can send different levels of audio to the processor by adjusting its DFX Knob. See the Effects section for an explanation of the available effects.
8. DFX Mute: Press this button to mute/unmute the effects.
9. DFX Peak LED: The LED will flash if the signal is clipping. If this happens, decrease the setting of your source channels' DFX Knobs. When the effects
10. DFX Return Fader (DFX Rtn): Adjusts the volume of the audio sent from the mixer's effects processor.
11. DFX Bypass: You can connect a standard 1/4" latching-style footswitch (sold separately) to this input and use it to bypass the mixer's internal effects processor (when the footswitch is in its "closed" position).

1. Phones Output: Connect 1/4" stereo headphones to these outputs. The Phones Volume knob controls the volume. The Phones Source button sets what signal is sent to this output.
2. Phones Source: When this button is raised, the signal from the Main Mix Outputs will be heard in the Phones Output. When this button is depressed, the signal from the Control Room Outputs (Ctrl Out) will be heard in the Phones Output.
3. Phones Volume: Adjusts the volume of Phones Output.
4. USB In Source: When this button is raised, the signal sent to the mixer through its USB Port will be sent to the Main Mix Outputs. When this button is depressed, the signal sent to the mixer through its USB Port will be sent to the Control Room Outputs (Ctrl Out).
5. USB In Level: Adjusts the level of the signal sent to the mixer through its USB Port.
6. 2 Track In Source: When this button is raised, the signal from the 2 Track In will be sent to the Main Mix Outputs. When this button is depressed, the signal from the 2 Track In will be sent to the Control Room Outputs (Ctrl Out).
7. 2 Track In Level: Adjusts the level of the 2 Track In.
8. Monitor Fader: Adjusts the level of the Aux Send 1 (Mon) output (the Monitor Mix).
9. Main Fader: Adjusts the level of the Main Mix Outputs.
10. LED Meters: Shows the audio level of the Main Mix Outputs. The Clip LED can light up occasionally, but if it happens too often, reduce the volume of the mix and/or individual channels.
11. Phantom Power: Activates/deactivates phantom power. When activated, phantom power supplies +48V to the XLR mic inputs and the LED next to the button will light up. Please note that most dynamic microphones do not require phantom power, while most condenser microphones do. Consult your microphone's documentation to find out whether it needs phantom power.
12. Power LED: Illuminates when the mixer is on.
13. USB Power Connection: You can use this USB port to connect and power (or charge) a device that requires power from a 5V USB bus.
