The output level is controlled by the AUX Level control (10). 6 BUS OUTPUTS 1 4 These BUS outputs feature 1/4'' TRS balanced jacks and provide signal from group outputs. The output level is controlled by the BUS Level fader. 14 XR-1016FX/XR-1824FX ANALOG MIXER MONO INPUT 1 MIC IN This XLR balanced mic preamp input supports sources with a gain range of 0 dB to -50 dB. All MIC/LINE inputs feature an 80 Hz high pass filter, which can be enabled to reduce low frequency pops, bumping and rattling noise when using a mic for vocals. 1 2 LINE IN (1/4) These jacks are 1/4" balanced (TRS) high impedance inputs. The cores are positive and used for unbalanced inputs. MIC IN and LINE IN should not be used at the same time. 2 3 GAIN May refer to MIC GAIN or LINE GAIN subject to input source. Using MIC IN, Gain Range: 0~50dB; Using LINE IN, Gain Range: -20~+30dB. Preferably set to a level where PEAK LED only flashes occasionally, so to prevent distortion. 3 4 LOW CUT 4 An 80Hz low cut filter toggle. Enable it to cut off unwanted low frequency noise (e.g., operating noise, stage noise, air noise) to improve clarity. These unwanted energy 5 could drain power from your audio system. 6 5 COMP Turning this knob clockwise lowers the compressor threshold, increasing the amount of compression. The compression ratio is within 4:1 and varies with the signal level and 7 the amount of compression. This is useful for controlling peak levels from live sources, and is designed to subtly tame the level of live vocals without noticeable artifacts. 8 6 HIGH EQ 9 This smooth-tilt tone control adjusts treble frequency levels (±15dB at 10 kHz), reducing noise or boosting brightness. 7 MID EQ The IF control is set to 1250 Hz, with a gain of +/-15 dB and a bell curve. 10 8 MID FREQ This control knob determines the center frequency of the MID EQ control. The center frequency of the bandpass filter can be set between 100 Hz and 8kHz. 9 LOW EQ This smooth-tilt tone control adjusts the bass frequency level (±15 dB at 100 Hz), adding 11 depth to thin sounds or clarity to overly thick sounds. 10 AUX1-4 12 13 Each channel of the XR-1016FX mixer provides 4 aux sends; AUX1 and AUX2 are PRE fader 14 sends. AUX3 is a POST or PRE fader send, depending on the position of the AUX3 PRE/POST button (32). FX/AUX4 send is always post-fader. FX/AUX4 is sent to the internal PRO DSP FX board. Signals in FX/AUX4 send are also routed to the AUX4 OUTPUT jack on the rear panel. 15 11 PAN 16 This control determines the signal position of the assigned L/R channel and group 1/2 bus. Turning the knob counterclockwise increases the amount of signal sent to the left channel and odd group; while turning it clockwise increases the amount of signal sent to the right 17 channel and even group. For example, when the GROUP SWITCH (17) is in the 1/2 position, turning the knob counter-clockwise will increase the amount of signal sent to Group 1, and turning it 18 clockwise will increase the amount sent to Group 2. Equal amount is sent to each group if rotated to the middle. 15 XR-1016FX/XR-1824FX ANALOG MIXER 12 MUTE SWITCH Pressing this switch will mute the signal sent to the main mix, aux sends, and FX effects. The mute switch does not affect the signal sent to the solo system. 12 13 13 MUTE LED 14 The mute button is equipped with a red LED that lights up when the channel is muted. 15 14 PEAK LED This LED usually indicates that the channel signal level is approaching clipping (distortion), 16 but it also lights up when muted. Because the peak indicator circuit monitors the signal after gain, EQ and master level, peaks can be caused by high settings of any of these controls. It lights up upon a static signal (test sound) of +15 dBu, which corresponds to the audible 17 peak of a highly dynamic signal (i.e. a piano). When lit, there is about 5dB of headroom remaining, and the gain and EQ boost should be reduced. Under optimal settings of input gain and EQ, LED will only flash briefly at the loudest peak. 18 15 PFL SWITCH This PFL button allows monitoring of the signal on this channel through a speaker connected to the CTRL ROOM OUTPUT or a headphone connected to the PHONES OUTPUT. 16 MAIN SWITCH This button allows signals to be routed individually to the MAIN MIX. 17 GROUP 1-4 SWITCH The BUS1/2, BUS3/4 buttons allow the signal to be routed to the stereo BUS 1/2, 3/4 respectively. 19 18 CHANNEL FADER Used to adjust the signal level of the channel sent to the main output; control range is - to +10dB, the optimal position is 0dB. 19 LINE/Hi-Z SWITCH To connect a guitar directly to the mixer without using a DI Box, press this switch down first; then connect the guitar's output to the channel's 1/4" TRS input. This helps to match the directly connected input impedance and preserve high frequency fidelity. The channel's 1/4" TRS input will become a line input, just like any other mono line input. To use guitars or other instruments on other channels, you'll need to use an external DI box first. Without the DI box or if this switch is not pressed the guitar may sound dull and muddy. STEREO INPUT 20 STEREO INPUTS (RCA) RCA L/R line input which accepts signal from MP3 or CD player. 21 STEREO INPUTS 1 1/4'' TRS balanced or 1/4'' TS unbalanced line inputs. If you are connecting a mono source, use the left (mono) input and the mono signal will appear on both sides of the main mix. 22 STEREO GAIN This control establishes the nominal operating level of the channel.

Trioatme alexvimel.ize3 To do so, set the channel fader to 0, then press the PFL switch and observe the LEVEL LED. If the CLIP LED glows and stays red, you need to reduce the gain. 23 LINE IN / USB-B IN SWITCH When this switch is not pressed, the input signal of this channel is provided by line input; or when pressed, provided by USB-B. 16 20 21 22 IN USB-B 23 XR-1016FX/XR-1824FX ANALOG MIXER PANEL 24 FOOT SWITCH This 1/4" TRS connector is where the foot switch is connected. The internal effect can be turned on and off through the foot switch. If the internal effect channel has been muted, the foot switch will not work. 24 25 25 PHONES OUTPUT This 1/4" TRS connector provides stereo headphone output. The output volume of this channel is controlled by the PHONES volume control knob. 26 L/R MAIN OUTPUT There are two 1/4'' TRS balanced jacks and two balanced XLR outputs for Left/Right outputs. 1/4" output can be connected with Tip, Ring, Sleeve (TRS) balanced or Tip, Sleeve (TS) unbalanced connector. Its output level is controlled by MAIN FADER (39). Both XLR and TRS outputs can be used at the same time. 27 CTRL ROOM OUTPUT These 1/4" jacks are usually connected to the input amplifier or headphone amplifier in the control room. 28 PHANTOM POWER (two on XR-1824FX) This switch applies +48VDC to the XLR input connector to power mics that require phantom power. If enabled, do not connect unbalanced dynamic mics or other XLR input devices that cannot handle this voltage. 29 FX TO AUX 1-3 29 31 This allows routing of signal in the FX return channel to AUX1-3 send. 30 AUX3 PRE/POST This button sets whether the AUX3/FX signal is pre-fader or post-fader. 31 AUX 1-4 MASTER These potentiometers control the AUX1-4 master level. When PFL button is pressed, the signal present on the respective individual aux output can be monitored through the speaker connected to the CTRL ROOM OUTPUT (27) or the headphones connected to the PHONES OUTPUT (25). 32 LEVEL LED This 12-LED level meter helps to control the main mix output level. Keep the output level below the "CLIP" LED to avoid signal overload and distortion. 33 PFL ACTIVE LED This LED illuminates when one or more of the PFL buttons are pressed. 34 CTRL ROOM VOLUME This is the level control of signal routed to the CTRL ROOM OUTPUT. During regular use, the main channel mix signal is routed to this output; when one or more PFL buttons are pressed, the PFL bus signal is routed to CTRL ROOM OUTPUT and PHONES OUTPUT. 35 PHONES VOLUME This knob controls the level of the headphone output. Set the headphone volume level to the minimum (-) before connecting 37 and wearing headphones to avoid hearing damage. 17 26 27 28 8 32 33 34 30 35 36 38 39 XR-1016FX/XR-1824FX ANALOG MIXER 36 MONITOR SETTINGS There are two buttons for monitoring settings. For the upper button: when not pressed, it monitors the audio from MAIN L/R; when pressed, it monitors audio from BUSSES. For the lower button: when not pressed, it monitors audio from BUS 1/2; when pressed, it monitors audio from BUS 3/4. 37 FX FADER This fader controls the signal level from the internal DSP effector. The mute button, when pressed, disables signal flow to the output bus or main mix. The PFL button allows the current channel's signal to be monitored by CTRL ROOM OUTPUT and PHONES OUTPUT. The MAIN button allows the effect signal to be sent to the main channel for mixing. The 1/2, 3/4 buttons allow the effect signal to be sent to the stereo busses BUS 1/2 or BUS 3/4. 38 BUS 1/2, BUS 3/4 FADER Faders BUS1/2 and BUS3/4 control the level of the stereo bus outputs. 37 38 39 BUS 1/2 and BUS 3/4 can be fed by each input channel to create stereo audio groups routed to the physical BUS OUTPUTS. When the MUTE button is pressed, signal flow to the BUS output or main mix is disabled. The MAIN button next to the BUS fader routes the BUS to the MAIN MIX. When the PFL button is pressed, the signal present in the BUS can be monitored through speaker connected to CTRL ROOM OUTPUT or headphones connected to PHONES OUTPUT. 39 MAIN FADER This fader controls the level of the MAIN MIX. 40 PREVIOUS TRACK 41 PAUSE/PLAY 42 NEXT TRACK 43 44 45 40 41 42 43 BLUETOOTH (BT) MODE LED 44 USB-A PLAYBACK MODE LED 47 46 45 USB REC MODE LED 46 EFFECTS SELECTION (1-16) KNOB & MODE SELECTION BUTTON 47 EFFECT STATUS (1-16) DISPLAY OPERATIONS a.
