Power Amplifiers/Transformers:

Product: CPS1 - Power Amplifier as manufactured by Bosch Security Systems. 5-way protection system with comparator circuitry which constantly monitors the input and output signals and activates the internal limiters whenever a non-linear operational state is encountered. This provides reliable protection of the connected loudspeaker systems against overload and clipping. Protection system provides on-board protection against thermal and capacitive overload, short-circuit and the occurrence of HF or DC at the output. 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. The electronically balanced inputs are provided via XLR-type and Phoenix connectors which are also used to loop the signal through. Using the Input Routing-switches allows the amplifiers to be 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 extremely silent running fans providing front-to-rear air circulation, guaranteeing trouble-free operation even in smaller power amplifier rack systems.
