4、d to combine QSCs legendary reliability and sonic quality into a low cost/high performance package. The com- pact size of the MX 700 makes it perfect for working musicians who dont want to carry bulky amplifiers, but still demand high power. It is also ideal for powering mid range drivers and tweete

5、rs in large sound systems. The MX 700 provides 170 watts per channel into 8 ohms, 270 into 4 ohms, and 350 into 2 ohm loads. The MX 700 uses 2-speed fan cooling to mini- mize operating temperatures and fan noise. Front panel gain controls and clip indicators make operational settings simple and stra

QSC is a pioneer in premium quality, high power, low profile amplifiers with thousands of units installed in touring systems and concert halls worldwide. The MX 700 puts QSCs proven tech- nology

7、 to work in a very economical package. The result is proven reliability at a new level of value. TUV PRODUCT? SERVICE geprfte? Sicherheit .

8、ces. The amplifier shall operate from 50-60 Hz AC power, with internal taps for selecting voltages 100,120, or 220-240 Vac. The amplifier shall operate from a normal household AC outlet, drawing less than 444 VA when driven with random program material at 1/8 rated power into four ohm loads. The amp

9、lifier shall be supplied with a single molded AC cord having an appropriate AC plug for the intended operating volt- age. 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. R

10、ack mounting shall be possible without clearance necessary between amplifiers for ventilation. 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

11、 transformer secondaries, power supplies, and protection systems. All pro- tection systems 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- mat

12、ched loads. Each channel shall monitor temperature of its heat sink, and shall trigger fan speed boost, and if necessary, signal muting to pre- vent excessive temperature rise. Each channel shall have on-off muting, acting for two seconds after turn-on, and within 1/4 second after turn-off or loss o

13、f AC power. Each channel shall have DC fault protection for the load. 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 front panel Gain control and a red LED sh

14、owing true amplifier clipping. The front panel shall also include a power switch and green LED power-on indicator. The output connectors for each channel shall include a touch proof bind- ing post. The input connectors shall be mounted on the rear panel and shall provide barrier strip and 1/4 connec

15、tions for each channel. Inputs shall be elec- tronically balanced, with a minimum impedance of 10 kilohms per side, and a common mode rejection of at least 50 dB from 20 Hz to 20 kHz. Each channel shall be capable of meeting the following performance cri- teria with both channels driven: Sine-wave o

16、utput power of 150 watts into eight ohms, and 225 watts into four ohms, 20Hz to 20kHz, with less than O.1% THD. Frequency response at 3dB below rated power shall be 20Hz to 20kHz within O.15 dB. The voltage gain shall be 35, equivalent to 31dB, and the input sensitivity shall be .96 Vrms. The signal

17、 to noise ratio over the range of 20 Hz to 20 kHz shall exceed 100 dB, A weighted. IHF damping factor shall exceed 200. The amplifier chassis shall occupy two rack spaces, with provision for securing the rear corners. Depth from mounting surface to tips of rear supports shall be 12.0 (30.5 cm). Weig

18、ht shall not exceed 25 Ibs. (11.3 kg.). The amplifier shall be the QSC Audio Products Model MX 700.
