13、 WEIGHTShipping53 lb; 24 kg; Net44 lb; 20 kg ARCHITECTS AND ENGINEERS SPECIFICATIONS The amplifier shall contain all solid-state circuitry, using complementary silicon output devices in a class AB output circuit. The amplifier shall op- erate from 50-60 Hz AC power, with internal taps for selecting

14、voltages 100,120, or 220-240 VAC. The amplifier shall operate from a normal house- hold AC outlet, drawing less than 580 VA when driven with random pro- gram material at 1/8 rated power into four ohm loads. The amplifier shall be supplied with a single molded AC cord having an appropriate AC plug fo

15、r the intended operating voltage. The amplifier shall employ forced-air cooling with a two speed fan for minimum acoustic noise. Air flow shall be from rear to front to avoid tem- perature rise inside the rack. Rack mounting shall be possible without clearance necessary between amplifiers for ventil

16、ation. The amplifier shall be capable of continuous operation at 1/8 power, into four-ohm loads, for ambient temperatures up to 104 F (40 C). The amplifier shall contain two independent channels, with separate AC transformer secondaries, power supplies, and protection systems. All pro- tection syste

17、ms shall be self resetting upon removal of fault, and the re- maining channel shall continue to operate. Each channel shall have inde- pendent protective circuitry against open circuit, short circuit, or mis- matched loads. Each channel shall monitor temperature of its heat sink and power transforme

18、r, and shall trigger fan speed boost, and if neces- sary, signal muting to prevent excessive temperature rise. Each channel shall have on-off muting, acting for three seconds after turn-on, and within 1/4 second after turn-off or loss of AC power. Each channel shall have DC fault protection for the

19、load, consisting of a load-grounding relay with fault fusing to interrupt power. Fault fuses shall be adequately large to prevent nuisance blowing at any output power the amplifier is capable of delivering. Each channel shall have the following controls and displays: A rear panel Gain control and Br

20、idge/Stereo/Parallel mode switch, front panel displays consist of a green LED power-on indicator; one yellow LED signal indica- tor, triggering at -30 dB; a red LED showing true amplifier clipping; and a red LED which indicates muting when illuminated. The output connectors for each channel shall be

21、 shrouded barrier strip connectors. The input connector shall be mounted on a removable panel to permit upgrades. The standard input panel shall provide detachable Euro-style header con- nections for each channel. Inputs shall be electronically balanced, with a minimum impedance of 10 kilohms per si

22、de, and a common mode rejec- tion of at least 50 dB from 20 Hz to 20 kHz. The standard input panel shall contain switches for mono-bridging and parallel inputs, and solder pat- terns for input isolation transformers, gain reduction resistors, and first- order high and low pass filters . The input pa

23、nel shall have enough space behind it to contain a circuit board measuring up to 5.9 wide by 4.1 “ deep. The multi-pin connector to the amplifier circuitry shall supply positive and negative DC supply cur- rents, and for each channel, balanced input signals, output signal, and clip/protect signal. O

24、ptional XLR and 1/4” RTS input connectors may be installed in place of a standard blank panel, mounted above the standard input panel. Each channel shall be capable of meeting the following performance cri- teria with both channels driven: Sine-wave output power of 200 watts into eight ohms, and 300

25、 watts into four ohms, 20 Hz to 20 kHz, with less than O.1% THD. Frequency response at 3 dB below rated power shall be within 0.2 dB. The voltage gain shall be 40, equivalent to 32 dB, and the input sensitivity shall be 1.02 Vrms. The signal to noise ratio over the range of 20 Hz to 20 kHz shall exc

26、eed 100 dB. IHF damping factor shall exceed 200. The amplifier chassis shall occupy three rack spaces, with provision for securing the rear corners. Depth from mounting surface to tips of rear supports shall be 17.9 (45.5 cm). Weight shall not exceed 44 Ibs. (20 kg). The amplifier shall be the QSC Audio Products Model CX6. 1675 MacArthur Boulevard Costa Mesa, California 92626-1468 USA Phone: 714/754-6175 Fax: 714/754-6174 RadioFans.CN 收音机爱 好者资料库
