YAMAHA CORPORATION YDA144
The YDA144 features Yamaha original non-clip output control function which detects output signal clip due to the over level input signal and suppress the output signal clip automatically. This is the difference from the traditional AGC (Auto Gain Control) or ALC (Auto Level Control) circuit. The independent power-down function for L channel and R channel minimizes consumption current at standby.| Part No. | YDA144 |
