Contractor precision series amplifiers

Complete Protection
The extensive and complete protection system features comparator circuitry, which constantly monitors the input and output signals and activates the internal limiters whenever a nonlinear operational state is encountered. This provides reliable protection of the connected loudspeaker systems against overload and clipping as well as on-board protection against thermal and capacitive overload, short-circuit and the occurrence of HF or DC at the output.
Additionally, special circuitry prevents the output-stage transistors from being damaged by Back-EMF. During soft start, delayed switching of the power outputs is accomplished via relays and a limiter controls the initial current inrush, preventing the mains fuse from being blown during the power-on operation.
Superior Flexibility
All models feature electronically balanced inputs that are provided via XLR-type and Phoenix connectors, which are also used to loop the signal through. Using the Input Routing switches lets you determine if the amplifiers are operated in stereo or monaural mode; “monobridged” operation is also possible.
The dB-scaled level controls are to be found on the rear panel. These potentiometers guarantee precise and reliable operation. In normal operation all CPS power amplifiers can be used to drive loads down to 2 ohms; in bridged mode the minimal load is 4 ohms. All amps are equipped with silent running fans providing front-to-rear air circulation, guaranteeing trouble-free operation even in smaller power amplifier rack systems.
Innovative Means Extra Reliability
In EV’s Class H design, rather than supplying the voltage for the maximum output power permanently, the permanent voltage rail is designed to cover the average music signal. If dynamic peaks require a higher output voltage, the voltage rail is switched to the maximum. This process saves nearly 50% of the power consumption in a conventional design and results in a dramatic reduction in heat output. The real test in a successful Class-H design is to make the voltage switching totally unaudible to the user. This is where EV’s amplifier engineering excellence makes the difference over other so-called “switching” designs. The audio performance of the CPS Class-H amplifiers speaks for itself. They truly set the new standard in Class-H amplifiers and meet the expectations we set in the original CPS models. All the CPS amplifiers have the ability to accept the XC crossover/filter cards. The 24dB crossover cards send by default lo-pass signal on channel A and hi-pass signal on channel B, but could be modified differently if needed. The XC5 for example is the perfect card to make a CPS2 or a CPS 2.6 or CPS2.8 to drive a standard cinema 2-way system. The XHP card with variable 12dB hi-pass filters per channel has a dedicated setting for the Sx600PI/PIX.

Contractor Precision Series amplifiers combine top-quality performance and reliability with innovative designs perfectly tailored to the needs of professional sound installation. Available in 2RU configurations of up to eight channels, CPS amps are compact and efficient to operate, with every detail thought through from the contractor's point of view. For fast installation and setup, each model features Phoenix-type input and output connectors, programmable power-on delay, remote power-on/off, rear-mounted attenuators and switchable high-pass filters.

For worry-free dependability, there's full protection against hazards, such as excessive heat, overloads, shorts, HF, DC, back EMF and inrush current. And for the ultimate in system control and supervision, the optional RCM-810 module enables the inclusion of CPS amps in IRIS-Net networks of up to 250 devices. Offering exceptional ease, flexibility and audio performance, CPS series is the ideal installation solution for cinema, club sound, commercial sound/life safety, and performance and sports venues.
