[. . . ] 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. CPS 2T * CPS1, CPS 2 THX approved, CPS 2. 4, 2. 6, 2. 8, 2. 11 pending " All Contractor Precision Series amplifiers are made to meet the highest requirements of any demanding application. The mechanical construction follows the highest precision standards of the industry. [. . . ] " THE CPS CLASS-H HIGH EFFICIENCY SERIES With the EV's new CPS Class-H series you get more of what you have come to expect from EV's original CPS power amplifiers: These state-of the art power amplifiers offer our proven original CPS performance and reliability in a new compact, lightweight format. This is made possible by incorporating a highly efficient Class-H design, which results in substantially less heat being generated. This allows the overall size of the amplifier to be reduced substantially without sacrificing performance or reliability. In addition, new features enhance the operational flexibility in many of your installations. And all of this is coupled to our comprehensive protection package present in all EV CPS amplifiers. · HIGHER EFFICIENCY · MORE FLEXIBILITY · MORE COMPACT FORMAT INNOVATIVE ENGINEERING 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. 1 kHz INPUT SENSITIVITY Rated power @ 8 , 1 kHz THD @ rated output power (<0. 1%, CPS2T@100V) IDE- SMTP 60 Hz, 7kHz DIM30 3. 15 kHz, 15 kHz MAXIMUM INPUT LEVEL CROSSTALK ref. 1 kHz, rated output power FREQUENCY RESPONSE ref. 1 kHz INPUT IMPEDANCE active balanced DAMPING FACTOR 1 kHz SLEW RATE SIGNAL TO NOISE RATIO (A-weighted) POWER REQUIREMENT POWER CONSUMTION POWER DISSIPATION 1/8 max. output power @ 4 PROTECTION COOLING DIMENSIONS (W x H x D) WEIGHT OPTIONAL ACCESSORY - 600W (590/580W) 1600W 1100 W 600W 900W 450W 500W (590/580W) 1300W 900W 1700W 1200W 1700W 1200W 52 V (121V/88V) 1800W 1200W 2200W 1600W 3200W 2200W 56 V 64 V 52 V 52 V 50 V 10 Hz . . . 60 kHz 62 V 72 V 78 V 32. 5 dB +2. 2 dBu (1. 0 Vrms) 33. 5 dB +2. 2 dBu (1. 0 Vrms) 35. 0 dB (42/39 dB) 0 dBu (0. 775 Vrms) 32. 0 dB +1. 15 dBu (0. 88 Vrms) < 0. 05 % 32. 0 dB +3. 2 dBu (1. 12 Vrms) 32. 0 dB +4. 7 dBu (1. 33 Vrms) 32. 0 dB +5. 8 dBu (1. 51 Vrms) < 0. 08 % <0. 03% < 0. 08 % <0. 03% (<0. 1%@100V) < 0. 08 % <0. 03% < 0. 02 % < 0. 01 % +22 dBu (9. 76 Vrms) < -80 dB 15 Hz . . . 40 kHz (±1 dB) 20 k > 300 < 0. 02 % < 0. 01 % < 0. 02 % < 0. 01 % < 0. 02 % < 0. 05 % (<0, 1%CPS2T@100V) 25 V/µs >105dB 30 V/µs >105dB 30 V/µs >100dB 35 V/µs 103, 5 dB 35 V/µs 105, 5 dB 35 V/µs 107 dB 35 V/µs 107 dB 240 V, 230 V, 220 V, 120 V or 100 V ; 50 . . . 60 Hz (factory configured) 690W 870W 870W 600W 500W 260W (885BTU/hr) 660W 320W (1090BTU/hr) 820W 396W (1350BTU/hr) 510W (1730BTU/hr) 650W (2220BTU/hr) 650W (2220BTU/hr) 396W (1350BTU/hr) Audio Limiters, High Temperature, DC, HF, Back-EMF, Peak current Limiters, Inrush Current Limiters, Turn-On delay Front to Rear, 3-stage Fans 483 mm x 88. 1 mm x 368. 8 mm (19" x 3. 5" x 15. 22") 15 kg (33. 1 lbs) 16 kg (35. 3 lbs) 22. 5 kg (49. 6 lbs) 13. 5 kg (30. 8 lbs) 15 kg (33 lbs) 16 kg (35. 2 lbs) 8. 15 kg (17. 96 lbs) Rear-Rack Mount Kit 18" (D) 112933, Filter cards please see below!

XC SERIES FILTER CARDS for CPS AMPLIFIERS: All the CPS amplifiers have the ability to accept the XC crossover/filter cards. The 24dB crossover cards (Linkwitz-Riley) 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 (e. g.
