DESCRIPTION

Congratulations! With buying an Electro-Voice CP-Series power ampliﬁ er you have chosen a state-of- the-art appliance that employs most advanced technology. CP-Series power amps combine outstanding audio performance, highest reliability and operational safety.

The audio performance of CP-Series power amps are simply extraordinary. The new switchmode power supply technology, completely designed from scratch and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output and conspicuous reduction in leakage power at the same time. The employed switching power supply combines the headroom-advantage of a transformer power ampliﬁ er with low weight of a pulsed power supply unit resulting in an improved performance-to-weight ratio. Special attention had been given to high efﬁ ciency and interference immunity already in the designing stage with the result that trouble-free operation of CP-Series power amps is possible even in EMV-critical environments. The power ampliﬁ cation stages of the CP3000S follow Class-H technology design, i.e. the power amp provides extremely fast, signal-dependent operating voltage switching, which, results in doubling the regular supply voltage when needed. 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. In other words: 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. Being protected against thermal and electrical overload, short circuit and the occurrence of HF/DC at the outputs, Electro-Voice CP-SERIES power amps fulﬁ ll even the most demanding requirements of Pro-Audio touring applications. 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 and an inrush current limiter additionally prevents mains fuses from blowing. Mechanical construction and workmanship also comply with the highest precision manufacturing standards. The robust chassis is extremely rigid which makes it especially suitable for wearing touring applications. Two three-speed high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running noise. Front-to-rear ventilation allows trouble-free operation even in smaller amp-racks. The electronically balanced inputs are carried out via XLR-type connectors. DirectOuts for through connecting the audio signal are also provided via XLRM-type connectors. Input Routing allows selecting DUAL (stereo) or PARALLEL (monaural) operation mode. By means of the separate BRIDGED OUT-connector and a Bridged Mode-switch, switching to “Mono Bridged” operation is truly uncomplicated as well. The recessed mounted dB-scaled level controls ensure reliable protection against mechanical damage. These particularly precise, secure to operate detent-potentiometers are located on the front panel. CP-Series power amps provide the opportunity for retroﬁ tting an internal analogue signal processor board with x-over and ﬁ lter functions. The easily readable LED display provides a quick overview of the power amp’s current operational status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely durable SPEAKON-type connectors. Also located on the rear panel is a Ground-lift switch, which, when needed, helps eliminating ground-noise loops by separating the power amp’s enclosure from the circuit ground. In normal operation, all CP-Series power amps are capable of driving loads as low as 2ohms. In Mono-Bridged mode the allowable minimum load is 4ohms. This owner’s manual outlines and explains several other features of your CP-SERIES power ampliﬁ er. Please, make sure to carefully read all of it and mind the instructions.

DESCRIPTION

UNPACKING & WARRANTY

Carefully open the packaging and take out the power ampliﬁ er. Next to the power ampliﬁ er itself, the package also includes this owner’s manual, a mains cord and the warranty certiﬁ cate. Keep the original invoice, which states the purchase/delivery date together with the warranty certiﬁ cate at a safe place.

INSTALLATION NOTES

Generally, installing or mounting CP-Series power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation. Installation of appliances with opposite air circulation within one cabinet or closed rack shelf system is not recommendable. When including appliances in a closed cabinet or rack shelf system make sure to provide sufﬁ cient ventilation. Leave a gap of at least 60mm x 330mm (up to the cabinet’s top ventilation louvers) for air circulation between the rear of the power ampliﬁ er and the cabinet’s/rack’s rear inner wall. Make sure to leave at least 100mm of space above the cabinet or rack shelf system. Since temperatures inside of the cabinet or rack shelf system can easily rise up to 40°C during operation, bearing in mind the maximally allowable environmental temperatures for all other appliances installed in the same rack shelf system is mandatory (also refer to “MAINS OPERATION AND RESULTING TEMPERATURE”).

Caution: For trouble-free operation exceeding the maximally allowable environmental temperature of +40°C is not permissible.

To prevent the front panel from bending, the use of installation rails or optionally available “rear-rackmount” rails is obligatory when installing the appliance in a rack shelf system or cabinet.

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. If guaranteeing the listed requirements is not possible on a long-term basis, regular servicing is absolutely mandatory to prevent the power ampliﬁ er from possible failure, mainly being caused by negative environmental effects. 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 ampliﬁ er 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). If foreign objects or liquids have entered the power amp’s enclosure, make sure to immediately separate the appliance from the mains network and contact an authorized service center for inspection before continuing operation.

INPUT A / INPUT B

The inputs INPUT A & INPUT B are electronically balanced offering input sensitivity of

+5.8dBu /1.51V (CP3000S) +7.0dBu /1.74V (CP4000S)

for direct connection of mixing consoles, signal processors, etc.

The XLR-type connectors OUTPUT A & OUTPUT B are prepared

for „through-connecting“ input signals to additional external power amps. 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. When using mixers with unbalanced outputs, bridging PIN1 and PIN3 of the power amp’s input connectors or leaving PIN3 of the cable’s plugs unconnected is necessary. Otherwise, when feeding in unbalanced audio signals via PIN3 (b, -, „cold“) and PIN2 (a, +, „hot“), strange humming and HF-interference may occur, which very likely will damage the power ampliﬁ er and/or the connected speaker cabinets.

NF-CONNECTION CORDS

Choosing high-quality balanced cables (two conductors for the audio signal plus separate shielding mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting unbalanced cables to the power ampliﬁ er inputs is possible as well, using balanced cables is always prefer- able. A great number of today’s audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and therefore efﬁ ciently eliminates the introduction of external interference – mostly noise and hum.

PARALLEL

The input connectors of channel A and channel B are electrically connected in parallel when the selector switch is set to PARALLEL. However, individually controlling the volume of both channels is still possible via the corresponding level controls A and B.

DUAL

If the selector switch is set to DUAL, the audio signals of channels A and B are independently ampliﬁ ed.

possible make sure to use the supplied mains cord for connecting the power amp to the mains network.

POWER AMPLIFIER OUTPUT CONNECTORS

Power amp output connection for the two channels A (left) and B (right) is provided via SPEAKON-type output connectors. A plastic cover to prevent inadvertent erroneous connection protects the BRIDGED OUT connector. Remove the cover only when actually operating the power ampliﬁ er in Bridged-Mode.

CAUTION!

Pins 2+/2- of the CHANNEL A SPEAKON output, which normally are not in use, are also connected to output B to ensure comfortable connection of 2-way speaker cabinets (e.g in Bi-Amping Mode) when using 4-wire Speakon cables.

To prevent short-circuit and/or to protect your speaker systems from being damaged when connecting the cabinets, please make sure to mind the Low- and High channels’ speciﬁ c pin-assignments! If, for example, the subwoofer audio signal is used to feed a tweeter, it is more than likely that this will instantly destroy the HF-driver’s coil.

WARNING: The speaker output terminals are marked with a symbol “ ”, which signiﬁ es that these terminals present a shock hazard to the user.

BRIDGED MODE

With the BRIDGED-MODE switch being engaged, using the channel A input for audio signal feed is mandatory, since input B provides no function. While the ampliﬁ er of channel A operates as usual. Additionally, the audio signal is internally inverted and routed to the ampliﬁ er of channel B. Both amps – A and B – now work in push-pull operation to provide doubled output voltage at the BRIDGED-OUT connector. The regular output voltage of each ampliﬁ er channel A + B is still present at the corresponding output connectors CHANNEL A and CHANNEL B. However, using these signals is not recommendable because of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms connected is not allowable.

CAUTION: Operating the power ampliﬁ er in Bridged-Mode may result in extremely high voltages being present at the BRIDGED OUT connector. The connected loudspeaker systems have to be designed for handling such high voltages. Please carefully read the power handling speciﬁ cations as stated in the documentation of the according loudspeaker system and make sure to check whether they are in compliance with the output capacity speciﬁ cations of the power ampliﬁ er.

GROUND-LIFT SWITCH

The ground-lift switch allows eliminating noise loops. When operating the power ampliﬁ er in a 19“ rack-shelf system or cabinet together with other equipment, setting the switch to its GROUNDED position is recommended. When operating the power ampliﬁ er together with appliances with differing ground potentials, set the switch to its UNGROUNDED position

MAINS INPUT

Under normal circumstances, the mains fuse only blows in case of fault. Replacing the fuse is only permissible for authorized service personnel using a new fuse of the same type with identical amperage, voltage and blow characteristics. The high-performance mains cord supplied with your power ampliﬁ er complies with applicable safety regulations, plus that its diameter corresponds to the power amp’s power output capacity. Whenever

Using a different mains cord with a smaller diameter results in higher leakage, consequently reducing the ampliﬁ er’s maximum power output capacity.

MAINS OPERATION & RESULTING

MAINS OPERATION & RESULTING POWER AMP TEMPERATURES

The following tables are useful in determining power supply and cabling requirements. The power drawn from the mains network is converted into acoustic output to feed the connected loudspeaker systems plus heat. The difference between drawn power and dispensed power is referred to as leakage power or 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. The following table is meant as auxiliary means for calculating temperatures inside of rack-shelf systems/cabinets and the ventilation efforts necessary. The column “Pd” lists the leakage power in relation to different operational states. The column “BTU/ hr” shows the dispensed heat amount per hour.
