LM15/LM15A

Thank you for purchasing Carvin’s LM loudspeaker system. This User Guide contains important information that will help you get the most from your Carvin LM loudspeaker so please take a moment to read it and be sure to keep it in a safe place for future reference.

LM FEATURES

• Available in both active powered and passive models (4 models)

• Powered models are bi-amped and time-aligned

• Ideal for live mains/monitor application

• Premium Neodymium woofers (LM15 - 3” voice coil, LM12 - 2.5” voice coil)

• Wide dispersion, asymmetrical HF horn

• Lightweight – only 26 Lbs (12 Kgs) for the LM12 and 31 Lbs (14 Kgs) for the LM15

• Rugged Polypropylene injection-molded enclosures

• Exclusive design facilitates use as mains or monitors

• Pole cups with thumb screw included for mounting on speaker stands

• Four suspension points for installation.

Powered Speakers

Carvin’s Powered Speakers amplification take the guesswork out of selecting the ideal power source to drive your LM loudspeakers. The active powered amplifiers are perfectly mated with the LM12A and LM15A loudspeaker systems. Powered LM loudspeaker systems make setup and operation easier with less gear to haul. Feed your mixer’s output or instrument directly to these loudspeaker systems, and you’re ready!

Powered features

• Direct connection to your music source (mixer/iPod)

• IN and OUT XLR’s for daisy chaining or, as a stand-alone PA/acoustic system

• 3 CH operation - for mic, instrument and iPod

• Powerful 3-band EQ with mid sweep feature

• Separate EQ for instrument channel

SUGGESTIONS FOR OPTIMAL PERFORMANCE

• To help control feedback, face loudspeakers away from microphones. The use of a graphic EQ will also help control feedback as well as enhance the overall sound.

• For optimal coverage and dispersion, elevate the loudspeaker above eye level.

• For passive LM systems (non powered), select an amplifier with a power capacity equal to 1 to 1.5 times the continuous power handling.

• Ensure all amplifiers are supplied and connected to properly rated AC power circuits. Underpowered amplifiers will cause premature clipping distortion and possible damage to drivers.

LIMITED WARRANTY

Parts and labor are covered for 3 years against manufacturer’s defects. Burned out drivers caused by excessive or insuficient power (creating distortion), physical damage caused by general use, moisture or dust are not covered by warranty. CAUTION: Square wave distortion from power amps can destroy drivers much faster than clean RMS power. The power generated by the internal power amps has the capacity to damage the drivers if driven too hard, in which case they would not be covered under warranty.

SPEAKER CABLES Use either Carvin’s 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 amplifier’s minimum impedance.

TROUBLESHOOTING TIPS

• If the protect LED illuminates, cycle power switch off for ten seconds and reapply power.

• Protect LED may illuminate due to the following reasons: overdriving, temperature, or failed speaker drivers.

• Be sure pole mount thumb screw is tightened to avoid rattling which could be perceived as audible distorion.

HELP SECTION

1) UNIT WILL NOT TURN ON: Check the power to the AC cord. Check for tripped circuit breakers, unplugged extension cords or power-strip switches that may be turned off. Check the fuse or circuit breaker on the unit if available. If the fuse has been replaced with the proper value and the fuse fails again, or the internal circuit breaker activates after reset, the unit will require servicing.

2) NO OUTPUT with POWER light ON: Shipping damage will be the primary reason for your product to not function properly. Please give us a call to help you determine the problem.

3) KEEP YOUR UNIT LOOKING NEW: Use only a dry cloth to wipe the control and venting areas. Surfaces without openings may be cleaned with a damp cloth.

RISK OF ELECTRIC SHOCK

DO NOT OPEN

This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

REFER SERVICING TO A QUALIFIED TECHNICIAN

1. INPUT 1 XLR and 1/4” (TRS) JACK

Use 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 SWITCH

Use 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 CONTROLS

The LEVEL on LINE/MIC 1, INPUT 2, and INPUT 3 adjust the overall volume.

4. INPUT 2

This 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 SWITCH

Press the switch “IN” to provide an alternate tone for instruments on INPUT 2.

6. INPUT 3

The RCA jacks are for iPod’s, 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 SWITCH

Press the switch “IN” to change the EQ. Use for pre-recorded music on INPUT 3.

8. ACTIVE EQUALIZATION

The 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 LED

If 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 LED

The 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 LED

Push 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 POWER

Use 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 XLR

Use 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.
