INTRODUCTION The new D.A.S. Variant series was designed for use in fixed installations, portable A/V, or applications requiring high SPL and control of the vertical coverage. The series comprises three models, the variant 25A which features two 5” speakers for mid-low frequencies and one compression driver (2” voice coil and 1” exit) coupled to a serpis-25 plane wave generator for the high frequencies. The variant 25A model can be used alone as a frontfill or under balcony unit for voice reproduction.
DESCRIPTION variant 25A The variant 25A is a two way class AB self powered system. Nominal amplifier power (Continuous) per way: LF:125 W HF:75 W. Amplifier panel description: A) LIMIT: Amplifier limiter indicator lights. When lit, the level of the signal source should be reduced. B) SIGNAL: Signal presence indicator at the amplifiers' inputs. C) ON: Indicator light for each amplifier channel. E1) AC INPUT: Blue PowerCon® NAC 3 FCA connector.
variant 112A i) ARRAY EQ: In order to compensate for the summing of the mid and low frequencies, the onboard signal processing of each variant 112A unit provides high frequency boost. The signal treatment has been designed to provide optimum response for arrays of 3 or more cabinets, so when employing just one or two units it may be appropriate to lower the high frequency level. The ARRAY EQ switch can be used to attenuate the equalization of the very high frequencies in -3 dB steps.
variant 18A Low frequency mono-amplified system. Nominal amplifier power (Continuous) 1250 W. Amplifier panel description: A) LIMIT: Amplifier limiter indicator lights. When lit, the level of the signal source should be reduced. I A B C B) SIGNAL: Signal presence indicator at the amplifiers' inputs. H G F C) ON: Indicator light for each amplifier channel. D E D) FUSE. E) AC INPUT: With PowerCon NAC 3 FCA connector.
Equalization Switch ON/OFF A sound system should be switched on sequentially. Switch on the self-powered unit last in your sound system. Switch on the sound sources such as CD players or turntables, then the mixer, then the processors, and finally the self-powered unit. If you have several units, it is recommended that you switch them on sequentially one at a time. Follow the inverse order when switching off, turning self-powered units off before any other element in the sound system.

The variant 112A can reproduce frequencies down to 63Hz , so in those applications where no high sound pressure level is required (speech, vocals, etc) and there is no need of extending the low frequency range the system can be installed without subwoofers. If it is required extending the low end then the variant 18A is recommended.
In applications like live sound concerts, disco dance music, where high sound pressure level is required double eighteen subwoofers should be used. DAS Audio recommends the LX-218CA. To align both systems an external DSP with two different signal lines will be needed. Note: the relationship between the number of subwoofers and the number of variant 112A depends on the application and is a parameter to be defined by the user.
Troubleshooting Problem Cause Solution No sound from the unit. The SIGNAL presence LED indicator(s) do(es) not light up. 1- The signal source is sending no signal. 1- Check that the mixer or sound source is sending signal to the UNIT. 2- Defective cable. 2- Check that the cable from the sound source to the UNIT is connected correctly. Replace the cable if defective. Full power cannot be obtained. The LIMIT LED indicator(s) never light(s) up. 1- The signal source does not have a hot enough output.
USING THE SYSTEM WITH SUBS SIGNAL INPUT SATELLITE OUTPUT When variant 25A units are used in combination with variant 18A subwoofers it is recommended to plug the mixer into the variant 18A's input and then to connect the variant 18A 138Hz high pass filtered output to the variant 25A input. The ratio between variant 25A and variant 18A units that DAS Audio recommends to achieve a correct balance is 4:1 (As it depends on the kind of music and the application, it is subject to changes).
When using a subwoofer other than the variant 18A in combination with the variant 25A units, it is recommended that external processor be used to filter the signal fed into the variant 25A units at 138 Hz. If an externally amplified subwoofer unit is to be used in combination with variant 25A satellites, the signal treatment will depend on the characteristics of the subwoofer used. In order to achieve a good quality sound, DAS Audio recommends the use of variant 18A subwoofers.

RIGGING SYSTEM Introduction This section contains needed information for flying D.A.S. Audio line array systems, description of the elements and safety precautions. To perform any operations related to flying the system, read the present document first, and act on the warnings and advice given. The goal is to the allow the user to become familiar with the mechanical elements required to fly the acoustic system, as well as the safety measures to be taken during set-up and teardown.
To facilitate the insertion of the connecting links in the corresponding slot of the top box, each angle has an associated pin hole which is labeled and located on each side of the box. Highly resistant 6mm quick release pins with a ball safety lock are used set the angles.
Most of the accessories needed to fly or stack the units are integral to the enclosures. The only additional items needed are the rigging bumpers. A) AX-V25 The AX-V25 rigging grid (bumper) is made from steel beams and is designed to handle great loads. It features a center reinforcement bar that is also used for the lifting slings. One chain can be used to determine the tilt angle of the whole cluster, depending on the hole used to attach the chain to the center bar.
C) AXW-V25 The AXW-V25 is made from stainless steel and has been specially designed to wall mount up to 3 variant 25A units. Six special M8x35 DIN912 screws must be used to attach the accessory to the wall. The whole cluster can be tilted as in the AXC-V25 accessory. Truss AXC-AT The AXC-V25 can also be used to pole mount up to two units on top of one variant 18A unit or on a tripod by making use of a special adaptor (AXCZT).
The AXC-V112 can also be used to pole mount up to one unit on top of one variant 18A or on a tripod by making use of special adaptor (AXC-ZT). M8x35 DIN912 screws AXC-V112 The AXC-V112 ceiling mount accesory features several holes on the top plate which allow for hook clamps to be fixed to it, so up to 2 units can be flown from truss structures. AXC-ZT Truss E) Quick release pins AXC-AT Each cabinet variant 25A/112A includes 4 steel heavy duty quick release pins stored on the rear panel.
Safety factors The safety factor is defined as the coefficient between the breaking load limit and the maximum safe working load limit (SWLL). In this case, the breaking load limit of each of the flying points is 875 kg (1925 lb) as determined by destructive testing in independent laboratories. With a 7:1 safety factor, a total amount of 20 units variant 25A can be suspended from the AX-V25.
APPENDIX: Line connections: unbalanced and balanced There are two basic ways to transport an audio signal with microphone or line level: Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them. Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono.
