Introduced a performance:        QG Series AT models for the power output set 4-16Ω/70V/110V resistance / pressure form.        QG Series AT models with reliable short-circuit. Overload protection device. When the power output of external short-circuit line. Local short circuit and the overload. Input signal is too large. Impedance matching (low resistance load, such as access to high impedance output load) caused more than set, automatically cut off the output, the occurrence of alarm hearing sound (PREPARE stop lights flash). At this point, should first turn off power switch, check the cause of the malfunction, failure to be removed, and then re-open the power switch.        QG Series AT models with pre-amplifier, microphone input with a three-way, which with silent sound microphone MIC1 strong interpolation function, two auxiliary line input, which can be accessed by CD / audio and telephone. For the convenience of the user using this product decoding with U disk function, and there are MP3 or WMA format music U disk with the machine connected to the disk U can play music, microphone and line. MP3 is independent and adjustable volume. The machine has a uniform tone control, so that can easily adjust the sound output, no line-out, access keys can be used recordings or other amplifier.         The machine has four divisions, each division will be an independent volume control and improve the practicality of it. Second, the technical characteristics:        1 Rated output power 200W 2 output format will be 4-16Ω resistance pressure 70V/110V; four district 110V output 3 the frequency response of 40Hz-18kHz ± 0.5dB 4 total harmonic distortion <0.2% (at rated output power) 5 part of the microphone signal to noise ratio> 70dB, line part of> 76dB 6 supply voltage AC220V ± 10% 50Hz-60Hz 7 size 480X370X88 (mm3) Third, they should pay attention to the use of items: 1. Class 1 aircraft for electrical appliances, use casing with the earth connection is possible, in order to against electric shock. 2. Microphone gain adjustment knob Tai from a young age, long for the smooth adjustment. 3. The use of 220V ± 10% .50 Hz-60H AC power supply. 4. Do not block air vents, so as not to affect the effect of heat dissipation. 5. Should avoid unnecessary load short-circuit. 6. If the machine is abnormal, non-professionals shall not open the machine for maintenance, in order to avoid electric shock accidents.
