TA2400电子混响放大器设有三级效果控制器:①残响深度控器(VR1),②延迟时间控制器 (VR2),③回音效果控制器(VR3),可产生山谷旷野及室内、礼堂或音乐厅的残响、回音等特技音效。其主要技术指标如下: 频率响应:10Hz～50kHz±1dB(在1kHz、深度电位器为0时) 输入电平/阻抗:150mV/50kΩ(同上) 总谐波失真:0.05％(在1kHz、1V、深度电位器为0时) 最大输入电平:2V(同上) 信噪比:90dB(在1V、深度电位器为0时) 混响时间:0～3s(在效果电位器拨至10、
TA2400 electronic reverb amplifier with three effects controller: ① reverb depth controller (VR1), ② delay time controller (VR2), ③ echo effect controller (VR3), can produce valley wilderness and indoor, auditorium or Concert Hall reverb, echo and other special effects. The main technical indicators are as follows: Frequency response: 10Hz ~ 50kHz ± 1dB (at 1kHz, the depth of the potentiometer is 0) Input level / impedance: 150mV / 50kΩ (above) Total harmonic distortion: 0.05% Depth potentiometer is 0) Maximum input level: 2V (above) Signal to noise ratio: 90dB (at 1V, depth potentiometer is 0) Reverberation time: 0 ~ 3s (in the effect potentiometer dial to 10,
