Guest room control host
The amplifier has at least 100~15,000HZ frequency response requirements; the deviation at rated output is +1/-2DB (equalization control reaches "flat").
The frequency response of the power amplifier is lower than 70HZ, attenuation with a slope of 6DB per octave.
The total harmonic distortion of the uncompressed amplifier can not exceed 0.5% at 1000HZ full output; it can not exceed 1% at 50% output.
At rated input, the output level error of the limiter circuit is less than or equal to 3DB, and harmonic distortion of less than or equal to 0.5% is generated when fully restricted.
The output of the amplifier meets the requirements of UIC 568 "Railway Passenger Car Audio Equipment" for frequency characteristics and distortion.
The power amplifier can not be damaged when the input or output is subjected to a short circuit or an open circuit.
The output power of the amplifier can fully meet the input requirements of the speaker.
The overall technical parameters of the guest room controller are as follows:
Power supply voltage DC110V, fluctuation range 77V~137.5V;
Size: 19-inch 3U chassis;
Operating temperature range: -21℃~+55℃;
Storage temperature range: -40℃~+55℃;
Vibration and shock; meet IEC61373;
EMC; meet EN50121-3-2;

产品描述
所有放大器采用固体元件设计。
放大器至少有100~15,000HZ的频响要求;额定输出时偏差为+1/-2DB(均衡控制达到"平直")。
功率放大器低于70HZ的频响,以每倍频程为6DB的斜率衰减。
无压缩放大器总的谐波畸变,在1000HZ满输出时可不超过0.5%;50%输出时可不超过1%。
在额定输入时,限制器电路输出电平误差≤3DB,在全限制时产生≤0.5%的谐波畸变。
放大器的输出符合UIC 568《铁路客车音响设备》对频率特性和失真的要求。
功率放大器能在输入或输出承受短路或开路时不损坏。
放大器输出功率能完全满足扬声器的输入要求。
客室控制器总体技术参数如下∶
电源电压 DC110V,波动范围77V~137.5V;
尺寸∶19英寸3U机箱;
工作温度范围∶-21℃~+55℃;
存储温度范围∶-40℃~+55℃;
