1.) MONO CHANNELS (MIC/LINE) - The mono channels offer balanced XLR connectors for low-impedance microphones and other low-level equipment.

2.) INPUT GAIN ADJUSTMENT - The input gain control has two different scales: one for microphones and one for line level devices.

3.) LOW CUT FILTER - The LOW CUT button activates a low cut filter (75 Hz, slope 18 dB/octave) for reducing low-frequency noise such as mains hum or handling noises from vocal microphones.

4.) STEREO CHANNELS - The stereo channels are configured as stereo pairs with 6.3 mm TRS jack input connectors. Mono signal sources should be connected to the left jack input connector.

5.)  +4 dBu/-10 dBV SELECTION - The line inputs of the stereo channels have a button for selecting the input sensitivity (+4 dBu for professional audio equipment, -10 dBV for general hi-fi devices, etc.)

6.) AUX SENDS - These 6.3 mm TRS sockets can be used to split the signal and send it additionally to external effects processors or the like. In addition, these outputs can be used as submix outputs.

7.)  PHONE - Headphones for monitoring the output signal (MAIN MIX) can be connected to this TRS socket. EQUALIZER - The mono input channels of the LAX16D are equipped with 3-band equalizers (HI/MID/LOW; MID: with adjustable centre frequencies), the stereo channels with 4-band EQs with fixed centre frequencies (HI, HI-MID, MID-LOW and LOW). The boost/cut range is +/-15 dB.

7.)  PHONE - Headphones for monitoring the output signal (MAIN MIX) can be connected to this TRS socket. EQUALIZER - The mono input channels of the LAX16D are equipped with 3-band equalizers (HI/MID/LOW; MID: with adjustable centre frequencies), the stereo channels with 4-band EQs with fixed centre frequencies (HI, HI-MID, MID-LOW and LOW). The boost/cut range is +/-15 dB.

8.) HI - This knob is used to control the high frequencies. You can use it to add more brilliance and presence to the corresponding signal or attenuate undesirably loud high frequencies (boost/cut range -15 dB to +15 dB, centre frequency 12 kHz).

9.) MID - This knob is used to control the midrange frequencies. These are the most important frequencies for musical instruments and the human voice (boost/cut range -15 dB to +15 dB). The FREQ knob is used to set the centre frequency that is to be boosted or cut (100 Hz to 8 kHz).

10.) HI-MID - This knob is used to control the hi-mids, which are slightly higher than the frequencies covered by the MID EQ. This provides even greater flexibility when it comes to equalization of the important midrange frequencies.

11.)  MID-LOW - This knob is used to control the mid-low frequencies (boost/cut range -15 dB to +15 dB, centre frequency 500 Hz).

12.) LOW - This knob is used to control the low frequencies. You can use it, for example, to boost a bass drum, bass guitar or male voice (boost/cut range -15 dB to +15 dB, centre frequency 80 Hz).

13.) AUX SEND CONTROLS - These two knobs are used to adjust the level of the signals sent to AUX buses 1 and 2. This does not affect the MAIN MIX output signal. AUX 1 can be configured as PRE or POST fader using the PRE/POST button. In the POST position (button not pressed) the signal is sent after the channel fader, meaning that the volume set for this channel also affects the AUX 1 signal. In the PRE position (button pressed), the signal is sent before the fader, so that the channel fader does not affect the AUX 1 signal. AUX 2 is a "post fader" path.

14.) PAN/BAL - The mono channels of the LAX16D have panorama (PAN) controls and the stereo channels have balance (BAL) controls, both of which are used to distribute the signal to the right and left output channels.

15 .) MUTE/ALT3-4 - Each of the channels of the LAX16D has a MUTE/ALT3-4 switch. This switch can be used to send the signal of the respective channel to the ALT3-4 output.

16.) SOLO - The SOLO switch lets you hear only the signal of the channel for which the solo function is activated (button pressed) without the other channels. The SOLO switch is especially useful for adjusting input levels (gain adjustment) and as a "preview" option for monitoring the respective signal.

17.) PEAK LED - All channels of the LAX16D are equipped with a peak LED for monitoring the respective audio signal. If the peak LED lights up (6 dB below the actual clipping threshold), this means that the signal is peaking and distortion may ensue

18.) CHANNEL FADER - This fader controls the overall volume of the respective channel, i.e., the level at which the signal is sent to the main mix.

19.) 2-TRACK IN/OUT

• TAPE IN: Use the TAPE IN input to connect a tape recorder or DAT recorder. Press the 2TK IN button on the front panel to send the signal coming from the connected device to the PHONES/CONTROL ROOM output or the 2TK TO MAIN MIX button to send it to the MAIN MIX output.
• TAPE OUT: The mix can be output to a tape recorder via these cinch (RCA) connectors.
• 2TK IN CONTROL: This control is used to adjust the level of the 2TK IN signal, which can be varied from ∞ to MAX.

20.)  STEREO AUX RETURNS - These 6.3 mm jack (TRS) sockets are primarily used to return the audio signal from an external effects processer to the mixer (MAIN MIX). In addition, these connectors can be used as additional AUX inputs. Note: If no connector is plugged into Aux Return 2, the signal of the internal effects processor is present on Aux Return 2.

21.) AUX RETURN CONTROL - This control is used to adjust the return levels of AUX paths 1 & 2, whereby the signals are added to the L/R MAIN MIX.

22.) EFX TO AUX 1- This switch routes the signal that is present at AUX RETURN 2 to the AUX 1 output so that the effects can also be heard in the monitor mix - which proves extraordinarily helpful in practice.

23.) AUX SEND CONTROLS - These controls adjust the master AUX SEND level (-∞ to +15 dB). This makes it possible to boost the AUX signals by up to 15 dB if necessary.

24.) LED LEVEL METER - The stereo level meter (12 segments) is used to monitor the level of the output signal.

25.)SOLO MODE BUTTON & SOLO LED [25]- These buttons are used to toggle between the two solo modes PFL (pre-fader listening, button not pressed) and AFL (after-fader listening, button pressed).

26.) ALT3-4 FADERS - These faders are used to control the level of the ALT output (control range -∞ to +10 dB).

27.) MAIN MIX LEVEL - These two faders are used to control the level of the signals sent to the L/R MAIN MIX and TAPE OUT outputs.

28.) TK TO MAIN MIX - When this button is pressed, the 2-TRACK IN signal is sent to the MAIN MIX output.

29.) ALT3-4 TO MAIN MIX - When this button is pressed, the ALT3-4 signal is sent to the MAIN MIX output and added to the output signal.

30.) CONTROL ROOM SOURCE - These buttons are used to determine which signal is heard via the monitor speakers or headphones: MAIN MIX, ALT 3-4, 2TK IN. Please note that these buttons are inactive in solo mode. If the selected signal cannot be heard after the CONTROL ROOM SOURCE buttons are pushed, please first check whether the solo mode has been activated in one of the channels.

31.) PWR LED (POWER) - This LED indicates that the mixer is on.

32.) PHANTOM LED - This LED indicates that phantom power has been activated.

33.) PHONE/CONTROL ROOM - This knob is used to control the level

34.) DFX MUTE SWITCH - This switch is used to activate/deactivate the effects module. If necessary, this function can also be controlled conveniently using a footswitch connected to the FOOT SW socket.

35.) DISPLAY - The selected preset is displayed here.

36.) PRESET SELECTOR - This knob is used to select the desired effects preset. There is a total of 100 presets available: Echo, vocal, plate and versatile two-effect combinations. Once you have selected the desired preset, press the knob to confirm your selection.

37.) PEAK LED - This LED lights up when the input signal reaches the clipping threshold. When the digital effects module is deactivated, this LED is illuminated constantly

Rear Panel Features:

38.) INSERTS (MONO CHANNELS) -  All mono MIC channels are additionally equipped with Insert sockets (stereo jack, TRS), via which external effects devices or the like can be patched into the respective channel. The signal is sent immediately after the input gain control (TRIM) to an external signal processor, for example, a compressor or limiter. Once the signal has passed through the external signal processor, it is returned to the same channel immediately before the EQ. Note: Connecting external devices to insert points requires a so-called "Y" cable.

39.)  CTRL ROOM OUTPUT - These 6.3 mm sockets are used to send the signal to studio monitor speakers (CONTROL ROOM) or a PA system.

40.)  ALT OUTPUT - These unbalanced 6.3 mm sockets serve as additional outputs. Their level is controlled using the ALT 3-4 fader in the master section of the mixer (max. +22 dBu). The signals of all channels for which the Mute/Alt 3-4 button has been pushed are routed to this bus; they no longer reach the main mix.

41.)  MAIN MIX OUTPUT - The L/R MAIN MIX OUTPUT has both XLR and 6.3 mm TRS sockets via which the main mix output signal can be sent to an amplifier. The output level is controlled by the MAIN MIX LEVEL fader (-∞ to +10 dB).

42.) FOOT SW - This socket can be used to connect an external footswitch for activation/deactivation of the integral effects processor (function identical with that of the DFX MUTE switch).

43.)  PHANTOM SWITCH - This switch activates the +48V phantom power for the four XLR microphone inputs. Important: Make certain that the phantom power is off before connecting microphones.

44.) POWER SWITCH - This switch is used to turn the mixer ON or OFF.

45.) AC INPUT - This socket is used to connect the power adapter.
