User manual ELECTRO-VOICE CPS-2T EDS

[. . . ] The CPS-2T has sophisticated protection circuits that guard it and the load from problems. Protection circuits guard against overload, over-temperature, shorted outputs, radio-frequency interference and dc faults. [. . . ] The power amplifier shall meet many worldwide product safety requirements including Underwriter's Laboratories UL-813 standard, Canadian Standards and CE standards. The power amplifier shall contain a limiter circuit driven by a high-quality input/output comparator to protect the load from damage by amplifier clipping. The amplifier shall contain sensing circuitry to provide protection for the output transistors against over temperature, excessive output voltage, shorted loads, excessive phase shift and back-EMF current. The load shall be similarly protected against start-up/shutdown transients, low ac line voltage and dc. Rear-mounted controls shall include detented dB-scaled level potentiometers for each channel, an input routing switch for selecting dual/stereo or parallel mono operation, a switch for selecting dual/ stereo or bridged operation and a chassis ground-lift switch. Rear-mounted input connectors shall include a 3-pin female XLR-type connector wired in parallel with a male 3-pin XLR-type output connector for signal routing. Output connector shall be a "Euro-style" Phoenix Contact 12-pin #KGS-MSTB2. 5/12 connector. Front-panel indicators shall include power on, a protection indicator and separate signal present and limiter indicators for each channel. The power amplifier shall meet the following performance specifications: rated output power from 20-20, 000 Hz at less than 0. 2% THD, each channel 330 watts into 8 ohms, 600 watts into 4 ohms as well as 25, 70 or 100 volt lines; In bridged mode at 1 kHz, the amplifier shall deliver 1, 200 watts into 8 ohms; THD (total harmonic distortion) shall be less than 0. 05% at 1 kHz at rated output power at 8 and 4 ohms, 0. 1% at 100 volts, 0. 2% at 70 volts and 03% at 25 volts; transient intermodulation distortion (DIM 30), shall be less than 0. 03% at 8 and 4 ohms, 0. 1% at 100 volts, 0. 3% at 70 volts and 0. 5% at 25 volts. Dimensions shall be 132. 5 mm (5. 25 in) high x 483 mm (19. 0 in) width x 385. 5 mm (15. 7 in) deep. The power amplifier shall be the Electro-Voice CPS-2T. Specifications: Conditions: 1.
