REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT. [. . . ] When the switch is down, the signal is sent ( See page 33 for details). (29) [OUTPUT LIMITER] switch Activates or deactivates the limiter function for all the buss outputs (stereo L/R outputs, group outputs 1 through 4, Aux send outputs 1 through 3, effect send output, and monitor outputs). When the switch is down ( ), the limiter function is active. 30 31 (30) [GROUP 1-4] faders Each fader adjusts the output level of the corresponding group output signal which is output from the [GROUP OUT] jack (See page 33 for details). (31) [STEREO] fader Adjusts the output level of the stereo output signal which is output from the [STEREO OUT (L/R)] and [ST MIX OUT (L/R)] jacks. 24 Model LM16 [Names and functions] Control unit (rear panel) 1 (1) [TO CONTROLLER] connector Used to connect to the [CONTROLLER] connector of the main unit using the supplied (or a different) CAT5 cable (See page 13 for details). <Note>: Use only a CAT-5 STP cable (straight type) for connection between the main unit and the control unit.

The connector is a combo type - a combined XLR connector and phone jack in one. You can connect a microphone to the XLR connector or connect a line signal to the phone jack. (Note that you cannot use the XLR receptacle and phone jack on a same combo connector simultaneously. ) See page 28 for details. (3) [AC IN] connector Used to connect the supplied power cord (See page 15 for details). <Note>: Use only the supplied power cord. A different power cord may cause fire, etc. Also note that when you hear thunder rumbling, disconnect the power cord from the AC outlet. (4) [POWER] switch (2) [INSERT (1 through 8)] jacks Each jack is used for connecting an external effects processor such as a compressor/limiter. To connect an external effects processor, use a Y-cable as shown below ( See page 31 for details). Turns on or off the LM16 (See page 15 for details). <Note>: Do not turn off the LM16 while accessing the internal hard disk. Even if you turn off the LM16, it consumes a very small amount of power. Therefore, it is recommended to disconnect the power cord from the AC outlet if you do not use the LM16 for a long time. 25 Model LM16 [Names and functions] (5) [PHANTOM (1-8, 9-16)] switches You can supply phantom power to the XLR INPUT connectors in eight channel groups (1-8 and 9-16) using these switches. When the [PHANTOM] switch is set to ON, the corresponding [PHANTOM] indicator on the control panel is illuminated (See page 28 for details). (13) [STEREO OUT (L, R)] connectors These XLR balanced connectors output the stereo L and R buss signals. You can connect these connectors to a power amplifier for driving main speakers on stage, etc (See page 16 for details). (6) [CONTROLLER] connector Used to connect to the [TO CONTROLLER] connector on the rear panel of the control unit using the supplied (or a different) CAT-5 cable (See page 13 for details). (7) [AUX SEND (1, 2, 3)] jacks Each of these unbalanced phone jacks outputs the corresponding AUX SEND buss signal at -2dBu nominal level. You can connect to a stage monitor, effects processor, etc (See page 16 for details). (8) [MIDI OUT] port Used to connect to the MIDI IN port of an external MIDI device. From this port, MMC (MIDI Machine Control command) is output (See page 40 for details). (9) [EFF SEND] jack This unbalanced phone jack outputs the EFFECT buss signal at -2dBu nominal level. You can connect to the input jack of an effects processor, etc (See page 16 for details). (10) [USB HOST] port By connecting a FAT16 or FAT32 USB memory stick to this port, you can also use the USB memory stick when upgrading the version (See page 37 for details). (11) [GROUP OUT (1, 2, 3, 4)] connectors These balanced phone jacks output the group buss signals at +4dBu nominal level. You can connect these jacks to input connectors of an external mixer, etc (See page 16 for details). (12) [ST MIX OUT (L, R)] jacks These unbalanced RCA pin jacks output the stereo L and R buss signals. You can connect these jacks to an external master recorder, etc (See page 16 for details). 26 Model LM16 [Mixer basics] Mixer basics Signal flow of the mixer A mixer accepts audio signals and modifies them, then mixes them. The following diagram shows how the input signals flow through the mixer section of the LM16. As the diagram indicates, an analog signal from the [INPUT] connector is level-adjusted by the [TRIM] control and converted to digital, then sent to the channel fader via the EQ. After the channel fader, the pan control adjusts the left and right (or odd and even) balance of signal sent to stereo left and right busses (or odd and even group busses). Then the stereo signal is finally level-adjusted by the [STEREO] fader and output from the [STEREO OUT (L, R)] connectors. In the diagram below, busses are shown as pipes. [. . . ] Damage to any product on which the original serial number has been defaced, modified or removed. Damage to or deterioration of the external cabinet. Damage occurring during shipment of the product. (NOTE: Shipping claims must be presented to the carrier. ) Damage resulting from accident, misuse, abuse or neglect. [. . . ]
