IMPORTANT SAFETY INSTRUCTIONS
The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the 
presence of uninsulated “dangerous voltage” within the 
product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance (servicing) instructions in the literature accompanying the appliance.
1.Read these instructions.
2.Keep these instructions.
3.Heed all warnings.
4.Follow all instructions.
5.Do not use this apparatus near water.
6.Clean only with a damp cloth.
7.Do not block any of the ventilation openings.
Install in accordance with the manufactures instructions.
8.Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat.
9.Only use attachments/accessories specified by the manufacturer.
10.Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
For US and CANADA only:
Do not defeat the safety purpose of the grounding-type plug. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. When the provided plug does not fit into your outlet, consult an electrican for replacement of the absolete outlet.
IMPORTANT SERVICE INSTRUCTIONS
CAUTION: These servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the Operating Instructions unless you are qualified to do so. Refer all servicing to qualified service personnel.
1.Security regulations as stated in the EN 60065 (VDE 0860 / IEC 65) and the CSA E65 - 94 have to be obeyed when servicing the appliance.
2.Use of a mains separator transformer is mandatory during maintenance while the appliance is opened, needs to be operated and is connected to the mains
3.Switch off the power before retrofitting any extensions, changing the mains voltage or the output voltage.
4.The minimum distance between parts carrying mains voltage and any accessible metal piece (metal enclosure), respectively between the mains poles has to be 3 mm and needs to be minded at all times.
The minimum distance between parts carrying mains voltage and any switches or breakers that are not connected to the mains (secondary parts) has to be 6 mm and needs to be minded at all times.
5.Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only permissible when using original parts.
6.Altering the circuitry without prior consent or advice is not legitimate.
7.Any work security regulations that are applicable at the location where the appliance is being serviced have to be strictly obeyed. This applies also to any regulations about the work place itself.
8.All instructions concerning the handling of MOS - circuits have to be observed.

Meeting the highest requirements of modern audio applications - especially, when it comes to sound pressure level, coverage and sound quality - is only possible when using active multi-component loudspeaker systems which provide the possibility to separately amplify and reproduce the audio signal’s individual frequency ranges. Active 2-way installations with additional sub woofer systems probably offer the best price-performance ratio. The low frequency range of the audio signal is reproduced by the sub woofers while high-quality full-range cabinets take care of the Mid/Hi frequencies and vocals.
One of the essential advantages when using active 2-way systems with additional sub woofers is the fact that the vocals are not divided between several speaker systems. This, in return, offers more convenience when adjusting the sound system. Unlike than with active 3- or 4-way configurations – difficult analyzing and measuring of sound fields is unnecessary.
Since locating low-frequency sound is merely impossible, simply using monaural sub woofers is absolutely sufficient for smaller stages or rooms. On wider stages it is indispensable to use individual sub woofer systems for both sides. Otherwise, the level differences between bass and treble would result in audible degradation of the overall sound. Of course, adding a centrally located sub woofer might additionally improve the sound quality.
The ACONE Controller has been designed to be used in high-performance installations that employ active 2-way systems plus sub woofers. Applications like these also mostly incorporate professional linear power amplifiers like the Electro-Voice P1200, P2000, P3000 or Q44, Q66. When using processor controlled power amplifiers like the Electro-Voice P1250, the processor section is simply switched off.
Installing and operating the ACONE Controllers is easy as can be since the user does not need to know any complex detail about crossover functions and equalization. All controls for matching the sound to different acoustic conditions and loudspeaker systems are located on the front panel. Difficult tasks - like electronic signal routing and settings for instance - are automatically carried out inside the appliance. The newly designed PowerMax12 crossover function (patents pending) optimally utilizes amplifier output power and loudspeaker transmission capacities. Compared to conventional crossovers or controllers, this results in an improved overall sound quality which is achieved with less effort.
The ACONE Controller is also most suitable for integration in active 2-way instrument reinforcement applications for keyboards, E-bass and drums. The PowerMax12 crossover function eliminates the often complained about “lack-of-punch-and-definition”, like it is common for conventional active musical instrument reinforcement systems.
Its excellent dynamic range of more than 116dB, the extremely low noise level and the outstanding price-performance ratio makes the ACONE Controller an advantageous alternative to conventional crossover and controller solutions – even in the critical field of permanent installation.
