REAR CONNECT PLATEThe Speakon™ jacks will accept 1/4 or Speakon™ connectors. 1/4cables can be inserted directly into the center of the connector.Use the second connector to DAISY-CHAIN up to one additional speaker in parallel. Speakon pin configuration is: 1+ Positive / 1- Negative SPEAKER CABLES Use either Carvins PRO50S speaker cable for up to 50 or high-current 12GA Speakon™ cables for lengths up to 150. 18GA cables are not recomended. You can DAISY-CHAIN up to one additional speaker per cable by using the unused speaker connector. Be sure the total impedance to the amplifier is not lower than the amplifiers minimum impedance. 1. INPUT 1 XLR and 1/4 (TRS) JACKUse these as the primary input from a mixer (or MIC, see #2). Using a balanced connection will reduce noise, which may be picked up by the cable. You may DAISY-CHAIN as many powered systems as you wish (see #13) however, not non-powered systems (see speaker cables). 2. MIC IN SWITCHUse the OUT position for normal line-level mixer input (note: if this switch is left IN, all signals from the mixer will be distorted). Press this switch IN to add 30dB of gain to the XLR and 1/4 inputs of INPUT 1 so that a microphone can be used. 3. LEVEL CONTROLSThe LEVEL on LINE/MIC 1, INPUT 2, and INPUT 3 adjust the overall volume. 4. INPUT 2This input is designed with a high impedance (>100K ohms) for instruments such as a guitar. Other sources such as keyboards or drum machines can also be connected. 5. INSTRUMENT SWITCHPress the switch IN to provide an alternate tone for instruments on INPUT 2. 6. INPUT 3The RCA jacks are for iPods, MP3 players, CD players, keyboards, and DJ mixers. The signals from the two RCA inputs are combined into a mono signal. For stereo operation, a second active speaker is required feeding the Left (White) and Right (Red) RCA of each system. 7. SHAPE SWITCHPress the switch IN to change the EQ. Use for pre-recorded music on INPUT 3. 8. ACTIVE EQUALIZATIONThe active powered loudspeakers offer a 3-band mid sweep equalizer for custom tuning to the acoustical environment. The EQ system is engineered specifically for the active powered loudspeakers featuring a modest boost and cut range of ±6dB to prevent radical adjustments that could otherwise compromise the system. The Mid-band sweep is particularly useful for enhancing critical mid range frequencies for stage monitoring or for cutting certain frequencies to compensate for room resonances. 9. PROTECT LEDIf the system should go into protect mode, the YELLOW LED will light and the power amps will shut off. This may occur if; a) the system is overheated due to clipping the power amps for an extended period of time, b) one of the internal drivers developed a short, or c) the power amps require service. 10. CLIP LEDThe RED CLIP LED will flash if the internal power amps start to distort. Turn the LEVEL controls down to avoid distortion. Damage to the drivers can result from operating at a level where the RED CLIP LED is constantly illuminated. 11. POWER SWITCH and LEDPush this switch to the ON position to apply power to the unit. The blue POWER LED will light to show the system is on. Power up your mixer first, then turn on the LM Active System. When shutting down, turn the LM active speaker off first, then turn off the mixer. 12. AC POWERUse a standard grounded AC cord. Whenever possible, use dedicated circuits for powered speakers. The powered speakers are available in either 120V or 240V models. 13. OUTPUT XLRUse the second XLR to link as many active powered systems as you wish. (see #14) 14. OUT MIX/THRU SWITCH (for daisy chaining additional systems)Press the switch IN for a direct PARALLEL connection to INPUT 1 only - use with external mixer and for daisy chaining other LM systems.With the switch in the OUT position, the combination of all channels including the EQ are sent to the #13 OUTPUT XLR. This unit becomes the master source for other powered systems.
