professional power amplifier

Performance description: TB Series amplifier's power output for 4-16Ω/70V/100V / (120V) fixed resistance / pressure form. TB Series with a reliable short-circuit power amplifier. Overload protection device. When the power output of external short-circuit line. Local short circuit and the overload. Input signal is too large. Impedance does not match (such as low resistance access to high impedance output load), such as caused by overload, automatically cut off the output, and a warning signal (PROT indicator constantly flashing). 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. TB Series amplifiers have pre-amplifier with two microphone inputs, one microphone with a silent tone functions, two auxiliary line input, which can be accessed by CD, tuner. Recording tape and so on. Microphone and line level are independently adjustable. Not all the way line-out, sound recording or keys can be used in other power sector, so that can easily adjust the sound output. Technical characteristics: 1 Rated output power 50W 2 output format will be 4-16Ω resistance pressure 100V (120V) 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 ±% 50Hz-60Hz 7 size 435X275X66 (mm3) Should pay attention to the use of: 1. It for Class 1 appliances, use of outside visitors to a reliable earth connection, in order to against electric shock. 2. Microphone gain adjustment knob Tai from a young age, slowly smoothing adjustment. 3. The use of 220V ± 10% .50 Hz-60Hz AC power supply. 4. Do not block air vents, so as not to affect the effect of heat dissipation. 5. To 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.
