Electro-voice CPS1, CPS 2, CPS 2T BROCHURE

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.

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 extremely silent running
fans providing front-to-rear air circulation, guaranteeing trouble­free operation even in smaller power amplifier rack systems.

The original CPS power amplifiers have provided reliable, clean
power amplification in thousands of fixed audio installations
worldwide. The CPS1, 2 and 2T continue to offer excellent value

for a variety of installations in churches auditoriums, convention
centers, factories, stadiums, etc., anywhere reliable performance
is needed and space is not at a premium.

THE CPS ORIGINAL AMPLIFIERS –
Exceptional Reliability and Value

The CPS1 can deliver up to 450 watts of power

at 1kHz into 4 ohms. The CPS 1 has been
extremely popular in smaller venues such as houses of worship,
retail spaces, and entertainment venues where background or fore­ground music is needed.

The CPS2 incorporates all the advanced fea-

tures of the CPS1 but can deliver up to 600 watts

of power at 1kHz into 4 ohms.

The CPS2T offers all the performance of the

CPS2 and adds the capability of 70v/100v con­stant voltage operation. It also features Transformer Saturation
Protection (TSP) that monitors the current demands of the 70v/100v
matching transformer and can protect against overload and distor­tion. The exceptions reliability and performance of the CPS2T has
made it the amplifier of choice for a wide variety of distributed audio
installations such as convention centers, factories, warehouses, sta­diums, office buildings etc. Anywhere large amounts of reliable 70v
amplifier power is needed the CPS2T can meet the spec easily.
