17、dard system comprises two ACTOR ADX 112 A mid/high units, two ADX 115 Sub A subwoofers and two ADX 115 Sub B subwoofers. Always connect ACTOR DX starting at the top and working your way down (refer to the diagram on the rear panel of ACTOR DX components)! This may seem unusual if you are accustomed

18、to working with active systems where signals are routed via paralleled pass-through jacks, which would allow connections to be made in any sequence. ACTOR DX, in contrast, features the DDO System Controller housed in the ADX 112 A mid/high unit. This controller lets you determine basic settings such

19、 as the system confi guration, the mid/high units level and the subwoofers level right on the mid/high unit. DDO then routes signals from the mid/high unit to Sub A. Note: Always connect cords in the correct sequence. Never connect a cord carrying a signal from a mixer directly to Sub A because this

20、 bypasses the DDO system controller! Always connect signal sources to the “master” system input located on ACTOR DX mid/high units! 3.2 ACTOR DX Full-range Setup The full-range setup comprises two ACTOR ADX 112 A mid/high units. Select the appropriate system confi guration on the system controllers

Connect cables from top to bottom as described above. Plug a microphone cord into the fi rst mid/high units THROUGH port to route

23、 the mixer signal to the second ACTOR DX stack. Ensure XLR connectors are wired as follows: 1= ground, 2= +, 3= - 3.5 Flying ACTOR ADX 112 A Mid/High Units Use the HK AUDIO rigging frame to fl y ACTOR DX mid/high units. To attach the frame, remove the countersunk M10 hex head bolts from the side pan

24、els. Bolt the rigging frames brackets to the enclosure. Set the mid/high units inclination to the desired angle by loosening the knobs on the sides and fi rmly hand-tightening them again. The serrated plastic washers hold the mid/high unit in place. Note: For reasons of safety, use tested and certif

25、i ed load-securing devices only (for example, half- couplers, TV spigots, brackets, and so forth)! Ensure wall and pole mounts are designed to handle the load (an ACTOR ADX 112 A weighs 30 kg). 3.6 Using the ACTOR DX Tilt Unit Using the optional tilt unit couldnt be easier: Proceed as if mounting th

26、e enclosure on a pole. Set the ACTOR DX tilt unit with the bottom plate facing down on the upper subwoofer and then set the ACTOR mid/high unit on it so the tilt units rod is inserted into one of the two holes (7.5 or 15). Question Can I connect speakers other than an ACTOR DX mid/high unit to an AC

27、TOR DX Sub A or Sub B subwoofer? Answer The system components are acoustically matched for optimum audio performance and may be operated in the indicated confi guration only. Using other mid/high units can degrade the sound and damage the power amp (e.g. the Sub As). Sub As nominal impedance is 4 oh

28、ms, and impedance may not fall short of this value. Connect no more than one Sub B to Sub As speaker out.

Connect other load consumers (for example, another ACTOR DX mid/high unit or an ACTOR DX Sub A bin) to it. Heads up: The Powercon Link socket can handle lo

32、ads up to 8.6 A and 2060 W (at 230 volts). This means you can use it to power up to but no more than two additional ACTOR DX components. Note: Always switch on ACTOR DX components one after another to prevent a sudden spike in the venues power supply. Otherwise the power surge may cause the house ci

33、rcuit breaker to trip. 4 Ground Ground lift button for separating the signal and chassis ground in the event of humming noises. In the event of low-frequency hum, engage the Ground Lift switch. The ground circuit is severed when this button is pressed. If this doesnt solve the problem, check all cor

34、ds connected to ACTOR DX as well as all signal cables routed to the mixing console for damage (see also Tips and Tricks). 5 Input Sensitivity This selector matches the preamps input sensitivity to the mixers output signal level. Engage this switch to select either -10 dB (for exam- ple, for unbalanc

35、ed 1/4” jacks and consumer level devices) or +0 dB (for example, for balanced XLR ports and professional mixers). Recommendation: Select +0 dB when using a professional-grade mixer sporting balanced outputs. This lets you take advantage of console faders full control range and helps prevent overload

36、s. Opt for -10 dB A when using a console with a lower output level (unbalanced 1/4 output). 6 Input Overload This LED lights up when the input level is too high and the entire system (preamp and controller) is being overdriven. Not only does this result in unpleasant distortion, it can also harm the

37、 systems components. If the red LED lights up, reduce the level (volume) at the mixer! 7 Line In Connecting cords: Connect cords carrying signals from your mixer (master left/right, line out, or a similar circuit) to the balanced inputs using a mic cord equipped with XLR connectors. Ensure XLR conne
