Milabar Through the use of an optimized power supply with dynacorx dispersion toroidal transformers as well as of Class H technology a large amount of headroom above the specified nominal output has been achieved along with a considerable reduction in weight and thermal leakage. The soft-start function limits against current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on. The Compact Linear Precision Series power amplifiers combine outstanding audio performance with maximum reliability and operating security as well as being markedly lighter than equivalent power amplifiers.

Do not use this apparatus near water. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fi t into your outlet, consult an electrican for replacement of the obsolete outlet.
Refer all servicing to qualifi ed 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 Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment 16 To completely disconnect this equipment from the AC Mains, disconnect the power plug from the AC receptacle The mains plug of the power supply cord shall remain readily operable.
Management of WEEE waste electrical and electronic equipment applicable in Member States of the European Union and other European countries with individual national policies on the management of WEEE The symbol on the product or on its packaging indicates that this product may not be treated as regular household waste, but has to be disposed through returning it at a Telex dealer. To reduce the risk of electric shock, do not perform any servicing other than that contained in the Operating Instructions unless you are qualifi ed to do so.
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 5Replacing special components that are marked in the circuit diagram using the security symbol Note is only permissible when using original parts 6Altering the circuitry without prior consent or advice is not legitimate 7Any 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. The audio performance of CL power amps are simply extraordinary. Optimised power supply units employing low-leakage toroidal transformers and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output. Compared to Class-AB power amps, Class-H power amps generate by far less power dissipation at identical output. Consequently, reduced leakage power or dissipation is synonymous to less waste heat — energy is used more effi ciently.
As a result, installing Class-H power amps within rack shelf systems is possible with less space between appliances. In addition to that and despite offering identical output, power consumption is a lot less than in Class-AB operation.
Back-EMF-Protection eliminates the risk of the output transistors being damaged by electrical energy back-feed. The power outputs are switched via relay with a time delay during soft-start. An inrush current limiter prevents mains fuses from blowing Mechanical construction and workmanship also comply with the highest precision manufacturing standards.
The rigid sheet steel chassis even resists the most wearing tour operation. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks.
The electronically balanced inputs are carried out via XLR-type connectors. The recessed mounted dB-scaled level controls ensure reliable protection against mechanica damage. These particularly precise, secure to operate detent-potentiometers are located on the front panel.
CL-Series power amps provide the opportunity for retrofi tting an internal analogue signa processor board with x-over and fi lter functions. In normal operation, all CL-Series power amps are capable of driving loads as low as 2ohms. Please, make sure to carefully read all of it and mind the instructions. Installation of appliances with opposite air circulation within one cabinet or closed rack shelf system is not recommended. When including an appliance in a closed cabinet or rack shelf system make sure to provide suffi cient ventilation.
Make sure to leave at least mm of space above the cabinet or rack shelf system. The power amplifi er has to be protected against: dripping or splashing water, direct sunlight, high temperatures or direct infl uence of heat sources, high humidity, extensive dust and vibrations Condensation on internal parts may occur when transporting the power amplifier from a cold into a warmer environment.
In that case operation is only permissible after the appliance has gained the new temperature after approximately one hour. The soft-start function limits against current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on. The loudspeaker outputs are activated via relay switching with a delay of approximately 2 seconds to effi ciently attenuate eventual power-on noise. This is normal, confi rming the correct operation of the protection circuitry.
POWER-indicator not lighting are: the appliance is not connected to the mains or the primary fuse is defective. The output relays interrupt the connected loads from the power amps while input signals are interrupted as well, preventing the connected loudspeaker systems and the power amplifi ers themselves from being damaged.
Whatever caused the fault — e. In case of thermal overload you have to wait until the power amplifier automatically regains normal operation The SIGNAL LED lights as soon as an audio signal of approximately 30dB below full odulation is present at the output. The LED is dimmed when speaker cables are hort-circuited or a protection circuit has been activated The 0dB LED lights whenever the power amplifi er is driven at its maximum.
Higher nput voltage does not result in higher peak output voltage. In addition, the 0dB dicator comes in handy when adjusting external limiters This indicator lights as soon as the integrated dynamic audio signal limiter is ctivated and the power amplifi er is driven at the clipping limit or generally at its aximum capacity.
To prevent distortion in mixing consoles connected to your CL-Series amp, setting these controls to a value between 0dB and -6dB s generally recommended. The voltage gain of all models is set to 32 dB constant gain. This results however in different input sensitivities for the different models see table , but the level adjustment of active crossovers or signal processors in multi-way systems is much easier.
Power amplifi ers with different output power can be changed without consideration, the crossovers have not to be adjusted due to the constant amplifi cation of the whole unit line.
The input signal is directly routed to these output connectors. There are no repeaters or other electronic components within that signal path. Accordingly, input and output connectors of the corresponding channel are interconnected in parallel, offering permanent electrical connection, without regard to the setting of the Power-ON switch Although having XLR-type output connectors, some mixing console models provide unbalanced output connection only.
Although connecting unbalanced cables to the power amplifi er inputs is possible as well, using balanced cables is always preferable. With balanced cabling, the shield connects all metal enclosure parts and therefore effi ciently eliminates the introduction of external interference — mostly noise and hum.
Make sure to remove the cover only when actually operating the power amplifi er in Bridged-Mode. While the amplifi er of channel A operates as usual, the audio signal is internally inverted and routed to the amplifi er of channel B. However, using these signals is not recommendable because of the aforementioned phase inversion. The connected loudspeaker systems have to be capable of handling such high voltages. Please make sure that power handling specifi cations as stated in the documentation supplied with your speaker systems match the specifi cations of the power amplifi er.
Replacing the fuse is only permissible when using a new fuse of the same type with identical amperage, voltage and blow characteristics. If the mains fuse blows more often, please contact an authorized service centre. Make sure to use the supplied mains cord for connecting the power amp to the mains.
Using mains cords with smaller diameters results in higher leakage and consequently reduced maximum power output capacity At V and V units the mains fuse is installed internally. This is fore safety reasons. In case of a blown mains fuse please contact a qualifi ed service personnel for servicing. The power drawn from the mains network is converted into output power to feed the connected loudspeaker systems and into heat.
The difference between power consumption and dispensed power is called power dissipation Pd. The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures.
