amplifier

Performance description: TB Series amplifiers are a 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 ) overload caused yes. that is automatically cut off the output to check the cause of the malfunction, and issued 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 are a pre-amplifier, with a three-way microphone input, one microphone with a silent sound features, 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 output lines can be used for sound recording or other power button access. The machine has a unified volume control, so that can easily adjust the sound output. TB Series has three divisions, to facilitate the control of each district to improve the practicality. Technical characteristics: 1 Rated output power 80W 2 output format will be 4-16Ω resistance pressure 100V (120V) 3 the frequency response of 40Hz-18Hz ± 0.5dB 4 total harmonic distortion ≤ 0.2% (at rated output power) 5 Letter to dry than the microphone part of> 70dB, line part of> 76dB 6 supply voltage AC220V ± 10% 50Hz-60Hz 7 size 480X370X88: 480X370X88 (mm3)Caution: 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.
