Controls and Functions INPUT CHANNEL SECTION - continued That means that the channel Fader also affects the level of a POST aux send. A POST Auxiliary bus is what you want to use (almost always) for sending to an effects processor, either internal or external. When using the POST aux sends, (while turning the channel Fader up or down) the level of effects will track the channel level correctly. independently on each channel.
Controls and Functions 12 – PEAK LED The L2400 and L3200’s MIC/LINE pre-amp also includes a PEAK LED which when illuminated, indicates that the signal is peaking or overloading. To reduce distortion, lower the GAIN control to keep this LED from staying on.

L2400 and L3200 Input and Output Connections CHANNEL - MONO MIC/LINE INPUTS on/off simultaneously for channels 1 through 20(28). XLR connector pin-out - Pin 1: Ground, Pin 2: Hot (+), Pin 3: Cold (-) The L Series mixers offer plenty of mono mic/line and stereo line input channels, sixteen on the L2400 and twenty four on the L3200’s, for connecting a variety of signal sources from microphones to line level devices such as synthesizers, drum machines and direct boxes.
L2400 and L3200 Input and Output Connections 8 - MAIN OUT B - 1/4-inch jacks In a live sound application, you can drive a second speaker system using the MAIN OUT B outputs connected to a power amplifier or powered speakers. In a recording application, the MAIN OUT B outputs are used to connect a stereo device such as computer sound card, MP3, or cassette recorder. The signal at the MAIN OUT jacks follows the MAIN OUT B level control knob allowing you to set a different level to the recorder.
L2400 and L3200 Input and Output Connections 14 - GROUP OUT - XLR 1/4" jacks 19 - Record Out - RCA jacks The signal present at this connector is the MAIN bus signal before it has passed through the MASTER level control and graphic equalizer. The nominal output level is -10dBV and the impedance is 100 Ohms.\ In a live sound application, you can connect additional zone speaker systems using GROUP OUT outputs connected to a power amplifier or powered speakers.
Using the USB I/O Using the USB I/O 3. Most of the time, you’ll want the output volume from the computer at the maximum position, but sometimes it defaults to the middle of the slider, making the output very quiet. The volume can be increased in several ways. The simplest is to click the loudspeaker icon (figure 3) in the system tray and drag the slider to the top (figure 4).
Using the USB I/O Getting Started with Windows XP - continued 5. To use the L Series as your default input/output device (for system sounds and programs like Sound Recorder), ensure that it is set for playback and recording in the Audio tab (figure 6). 2. To select the L SERIES as the computer's audio input, open the System Preferences from the dock or the main Apple Menu (figure 8). Figure 8 3. Next open the Sound preference (figure 9). Figure 6 6.
Using the USB I/O Getting Started with MAC OS X - continued 5. Next, click in the Output tab and select USB Audio Codec (figure 11). You may notice that the Volume slider sets itself to the full level. This will allow you to have full range using L Series’ hardware MAIN Volume control. You can also assign the USB out to feed from the AUX1 and AUX2 outputs enabling you to build a stereo mix for recording that’s independent from the house sound system.
L2400 and L3200 Wiring Guide CONNECTING THE L2400 and L3200 There are several ways to interface the L2400 and L3200 to support a variety of applications. The L2400 and L3200 feature balanced inputs and outputs, so connecting balanced and unbalanced signals is possible.
