Components

Subwoofer

The L.U.C.A.S MAX

subwoofer’s housing is split into two chambers. The front chamber serves as the speaker cabinet for the 15" direct-loaded loudspeaker, which has a power-handling capacity of 1,200 W RMS and a nominal impedance of 4 ohms. The active electronic circuitry, the power unit, DDO™ digital controllers and Class D power amps are housed in a separate compartment at the rear of the cabinet.

Satellites

Satellites are loaded with a 10" HK Audio Custom speaker and a 1" compression driver with a 60° x 40° CD horn. They are rated for 400 W RMS powerhandling capacity and a nominal impedance of 8 ohms.

The newly developed, integrated DuoTilt™ pole mount allows sound energy to be utilized far more efficiently. It minimizes annoying ceiling reflections, thereby achieving a clearer, tighter, and more focused sonic image. The cabinet is always stabilized at its center of gravity - no wobbling, tilting, or unintentional turning.

2 Transport

To transport the system, simply set the subwoofer on its casters and place the satellites onto the subwoofer with the foam-rubber grille side facing down. Secure the satellites, for example, using a locking strap. Use original HK AUDIO L.U.C.A.S MAX

‚ protective covers to gear up your personal system for the rigors of the road. Amply padded and protected against moisture, your L.U.C.A.S MAX®is sure to deliver satisfying performance for a long time to come.

More about limiters

Limiters are designed to protect power amps and the speakers connected to them from damage. The functionality and response of a limiter is determined by parameters called attack time, threshold and release time. Adjusting these parameters incorrectly can degrade the sound and bring about dynamic distortion. At peak volume levels, for example, vocals may fail to cut through the mix and instruments that are played percussively may lose their punch and dynamics.

HK AUDIO limiting technologies are more than merely technical tools serving to protect components. We put a premium on authenticity, that is, retaining an audio event’s true dynamics. This explains why our limiters are first and foremost designed to optimise the sound, though they of course also protect the system.

3 Connections and Control

Features

L.U.C.A.S MAX Subwoofer

1 Limiter LEDs

Much like rev counters, these LEDs indicate the active system’s operating status. For more info, read the sidebar “More about Limiter LEDs.”

2 Gain

Operation: Turn the Gain knob all the way down (counterclockwise) before switching the system on. Ensure the system is connected to the satellites and all other connected components are on before powering it up. Be sure to switch on the connected mixer as well as all signal sources connected to it, for example, keyboards, amps, effects, and so forth.

After you power the system up, set the Gain knob to the 0 dBV or 12 o’clock setting. This is the preferred level if you have connected a mixer. (Note: If you connect a CD player or a keyboard directly to the system, you may not be able to achieve peak volume at this setting. If this is the case, twist the Gain knob to the far right.)

If you hear distortion or a saturated signal, first check the signal sources and, if possible, reduce the output signal level there. If you are unable to turn down the level of the signal sent to L.U.C.A.S MAX

at the signal source, adjust the input sensitivity using the Gain knobs. (see also Tips and Tricks— section 4).

3 Balance

Operation: Twist the Balance knob to the left or right to adjust the relative balance of levels between the left and right channels.

4 Display

Display: The numeric display indicates the currently selected system configuration (0 to 5).

0 Mute . . .System is muted 1 Speech . .Voice/speech setup (announcements) 2 Live 1 . . .Gig setup 1 3 Live 2 . . .Gig setup 2

4 DJ 1 . . . .CD playback setup 1

5 DJ 2 . . . .CD playback setup 2

Note: A flashing display indicates that the controller has muted the input. This mute function is triggered via the input signal level. The system is muted when its level falls below the threshold value. The system is enabled as soon as the input signal level rises above the threshold value.

5 Up/Down Buttons

Press these buttons to change system configurations. Operation: Simultaneously press and hold the Up and Down buttons for about 1-2 seconds. Once the letter U (Unlock) appears briefly in the display you can use the Up and Down buttons to select the desired setup. The buttons lock again automatically after a moment, at which time the letter L (Lock) appears briefly in the display.

6 Subwoofer Level

Handling: When this knob is set to the 12 o’clock position, the subwoofer’s and the satellite’s respective volumes are matched, ensuring the proper balance between the subwoofer’s bass output and the stallites’ mid/high-range output. If desired, you can twist the Subwoofer Level knob to the left, i.e. counterclockwise, to cut the subwoofer’s level by as much as -12 dB and to the right to boost it by as much as 6 dB.

7 Ground

Ground lift button for separating the signal and chassis ground in the event of hum. To rid the system of low-frequency hum, press the Ground switch in. If this doesn’t solve the problem, check all power and audio cables connected to L.U.C.A.S MAX®for damage, as well as all cables routing signals to the mixing console (see also Tips and Tr icks in Section 4).

8 Input Left and Input Right (Combination XLR/1/4"

jacks) L.U.C.A.S MAX®is equipped with separate left and right channel inputs for connecting to a mixer.

Connections: Connect the audio cables that route the signal coming from your mixer (master left/right, line out, or a similar circuit) to these balanced inputs using microphone cables equipped with XLR connectors. The XLR connectors’ pin assignments must be as follows: 1= ground, 2= +, 3= -. You can also use a 1/4" Tip-Ring-Sleeve plug to route signals via balanced circuits. Unbalanced signals can be patched in via a mono plug.

9 Through Left, Trough Right

Connections: Parallel outputs for routing the line signal (left or right) to other systems, outboard components, monitor power amps, etc., via XLR cables.

10 To Satellite Left und Right

Connections: Connect these Speakon

outputs to the left and right L.U.C.A.S MAX®satellites using speaker cables equipped with Speakon

connectors. Note: Be sure to rotate the Speakon®connectors clockwise until they lock in place!

11 Power Switch

Operation: On/off switch for the active system. The display on the system controller glows orange to indicate that the system is on.

Note: Once you have engaged the Power switch, it will take several seconds for the display to light up and the system to be ready for operation. This is standard procedure and does not indicate a malfunction.

The active L.U.C.A.S MAX

system should always be switched on last after you power up all equipment connected to it, and should be switched off first before you switch off all the other equipment connected to it.

12 Mains Input

Connections: Use the factory-included Powercon

mains cable (power cord) to connect from this socket to a wall receptacle. Caution! Make sure the local mains voltage matches the voltage specified on the device. Connecting the system to the wrong mains voltage may destroy the L.U.C.A.S MAX

system’s electronic components.

13 Fans

These fans (on the side of the housing) keep the power amp modules cool. Always keep the fan and ventilation vents free of dirt and debris, and ensure they remain unobstructed so air can circulate freely.

L.U.C.A.S MAX Satellite

Input

Connections: Connect the Speakon®inputs to the left and right L.U.C.A.S MAX®satellite outputs using speaker cables equipped with Speakon

connectors. Note: Be sure to twist the Speakon®connectors clockwise until they lock in place! You must first disengage the safety catch before you can unplug the connector. To do this, pull the bayonet catch towards the cord.

4 Tips and Tricks

• Do not expose electronic circuitry to moisture! When you set the system up outdoors, be sure to protect it against rain. Keep soft drinks, beer or any other liquids well away from the cabinets to protect their electronic components from short circuits.

• To ensure proper ventilation, make sure the subwoofer is placed a sufficient distance away from walls and isn’t covered by curtains and the like. This is vital to keep the power amps cool.

• Ensure that the vents on the subwoofer’s side panels are free of dirt and that the fan blades can rotate freely. Otherwise, electronic components may overheat and suffer damage.

• L.U.C.A.S MAX

takes care of delivering optimum sound—so provide it with optimum input signals! Noise such as hum is generally caused by defective cables, the wrong type of cables, or unbalanced signals being fed to the mixing console. Check all audio cables and mains cables.

• Avoid distortion! Not only is it unpleasant to your audience’s ears, it also endangers your equipment. Make sure all components that are connected directly and indirectly to L.U.C.A.S MAX

have sufficient power ratings, and that they are not distorting from being driven at their respective limits. Provide a clean, undistorted signal to the system that won’t require backing off the Gain knob to clean it up.

• Avoid ground loops! If, for example, you connect the mixer to one mains circuit/wall outlet, and L.U.C.A.S MAX®to another, you may encounter a ground loop. To prevent this problem, always connect the L.U.C.A.S MAX®system and the mixing console to the same electrical circuit (same phase!). If your equipment hums despite this precaution, the Ground Lift switch can be a great help.

CAUTION: Never tape over the plug’s ground terminal–this endangers lives!

6 Troubleshooting

The display does not light up when switched on.

1 Check if the power cable is plugged into the Mains

Input.

2 Check if the mains power supply is providing

current.

The display lights up, but there is no sound coming from the cabinets.

1 Check the cables connected to the Left and Right

inputs.

2 Check if the signal sources (mixer, keyboard, CD

player) are on. 3 Is the Gain knob turned up? 4 Check the speaker cables for damage. 5 Check if the Speakon“ connectors are fully engaged

in their sockets (rotated to the right). They must be locked in place to establish an electrical connection.

The subwoofer’s low frequency output is too soft.

1 Check the setting of the Subwoofer Level knob.

Adjust this knob to set the volume of the subwoofer to the desired level.

Sound seems distorted.

1 Check the LED displays on your mixer. They should

not be constantly in the red. If necessary, reduce the volume at the mixer.

2 If the LED displays on your mixer are in the green,

turn back L.U.C.A.S MAX

’s Gain knob.

3 Watch the LEDs of the Limit Left, Limit Right and

Limit Subwoofer displays on L.U.C.A.S MAX

’s control panel. These may light up yellow, but only intermittently. Under no circumstances may they continuously illuminate yellow. If this is the case, turn the Gain down (knob counterclockwise).

Annoying hum

1 Check the cables connecting the source of the

audio signal to L.U.C.A.S MAX®. Replace any damaged cords.

2 If you cannot pinpoint the cause of the humming,

press the Ground switch in. This should remedy the problem in most cases.
