INPUT CHANNEL SECTION

The following section details each part of the L1200 and L2000’s INPUT CHANNELS including the LOW CUT, 3-BAND EQ, the MONITOR and EFX sends, PAN, GAIN and VOLUME controls.

1 – PEAK LED

The L1200 and L2000’s MIC/LINE pre-amp also includes a PEAK LED which, when illuminated, indicates that the input signal is near overload.

2 - GAIN Control Knob

Each of the L1200 and L2000 channel’s pre-amp stage has a variable GAIN control to help set a clean level. The Mic/Line inputs’ GAIN control has a range of -6 to -50dB on the MIC input and +14 to -30dB on the LINE input. The Stereo inputs’ GAIN control has a range of -10 to -50dB on the MIC input and +20 to

-20dB on the LINE input.

3 - LOW CUT Switch

Each of the L Series’ channels include a LOW CUT (or high pass) filter which rolls off the low frequencies from 75Hz and below at the rate of 18dB per octave.

Auxiliary Buses ( 4 - 7 )

The L Series include several auxiliary signal paths, or buses, that can be used to create independent mixes for sending to the internal or external effects processors, or to an external monitor system. These buses start by sending the signal from each individual channel, which is set with one of the auxiliary control knobs. Then, the mix of all the channels auxiliary level is ultimately sent to either an internal effects processor, or to an output jack to connect to an external effect or monitor system. To help you control your effects and monitor mixes, the L series has four auxiliary buses, with switching to give you a possibility of 2 monitor mixes with two effects sends, or 3 monitor mixes and one effects send.

1 to 24 on the L2000 1 to 16 on the L1200

25/26 to 31/32 on the L2000 17/18 to 23/24 on the L2000

PRE….? POST….? What’s That?

In order to operate your mixer correctly, it is important to understand the concept of PRE and POST fader sends. An auxiliary bus that is set up as PRE Fader routes, or sends, the signal to its output from a point in the channels’ circuit that is electronically before the channel Fader. That means the channel Fader has no effect on the PRE aux level. A Pre Fader send is what you want to use for a monitor mix, so when the level is changed for the mix in the main PA speakers using the channel Fader, the level in the monitor set by the aux control

Controls and Functions

INPUT CHANNEL SECTION - continued

knob remains the same. An auxiliary bus that is set up as POST Fader routes, or sends, the signal to its output from a point in the channels’ circuit that is electronically after the channel Fader. 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.

4 – AUX 1-2 Pre Fader Send

Each of the L series’ input channels include a pair of Pre Fader Auxiliary sends; AUX 1-2 and their control knobs adjust the amount of that channel’s signal that is sent to the AUX 1-2 Output. The signal feeding AUX 1-2 is sent before, or pre, the channel Fader, so the channel Fader has no effect on the AUX 1-2 output levels. The AUX 1-2 buses are usually used to create a separate mix for a floor monitor system.

5 – AUX 3 Pre/Post Fader

Each of the L series’ input channels include an Auxiliary send (AUX3) which can switch from Pre to Post sends; AUX 3 and their control knobs adjust the amount of that channel’s signal that is sent to the AUX 3 Output. Aux 3 can be configured for pre or post fader send using the PRE/POST switch (6). The AUX 3 bus is usually used to create a separate mix for a floor monitor system, but you can set the Pre/Post switch to Post to use the send as en effects bus to an external processor.

6- PRE/POST switch

The PRE/POST switch is used to select the point that the AUX 3 bus uses to send the signal. When the PRE/POST switch is set to PRE, the signal feeding AUX 3 is sent before the fader, so the channel Fader has no effect on that level. This is the normal setting when using AUX 3 as a monitor send. When the PRE/ POST switch is set to POST, the signal feeding AUX 3 is sent after the fader, so the channel Fader has an effect on that level, meaning the Aux level tracks up and down with the channel Fader. This is the normal setting for using AUX 3 as an effects send, since in most applications when you set the channel louder you want the effect to get louder too. When you move the Channel Fader up or down the level of effects will track the channel level correctly.

7 – EFX- Post Fader Send

The L series provide high quality, 24 Bit digital effects, and the level of effects can be set independently on each channel. The channel’s EFX knob controls the amount of signal that is sent to the EFX bus feeding the internal DSP effect processors.

8 - Channel Equalizer - Mono Channels

The L1200 and L2000 mic/line input channels incorporate a 3-band, swept-mid equalizer allowing you to adjust the high, mid-range, and low frequencies independently on each channel. The frequency centers, range of boost or cut, and equalizer type for each band are described in the following section:

HF (HIGH FREQUENCY) 12kHz +/- 15dB Shelving type

The channel’s HIGH frequency response is flat when the knob is in the “12:00” position. Rotating the knob towards the right will boost the channel's high frequency response at 12 kHz by 15dB, and rotating it towards the left will cut the high frequency by 15dB.

MF (MID FREQUENCY) CUT & BOOST

The MF knob is used in conjunction with the FREQ knob to create the tonal shape in the midrange frequency when using the mono channel’s equalizers. You can adjust the frequency on the mid-range control with the FREQ knob, and use the MF control to either boost or cut that frequency by plus or minus 15dB. The channel’s MID frequency response is flat when the MF knob is in the “12:00” position.

FREQ (MID FREQUENCY) Variable 100Hz – 8K

The FREQ is a control enabling you enhanced capabilities in the tonal shaping of the input channel signal. Thanks to the FREQ control, you have a variable mid-range equalizer, allowing you to pin point the exact frequency you want to boost or cut. The MID SWEEP has a “fixed Q” of two octaves (the amount, or width, of frequencies
