Features

• BTL 20 W × 2-channel (4 Ω), GV = 40 dB
• Built-in various protection circuits (thermal protection, short circuit to VCC and short circuit to GND, VCC-open short circuit to VCC , GND-open short circuit to GND, overvoltage and supply surge, and ASO, etc.) Especially, the supply surge breakdown voltage is 100 V or more. GND open breakdown voltage is 16 V or more.
• Built-in standby function Free from shock noise at STB on/off.
• Built-in muting function Free from shock noise at mute-on/off. Adapting attenuator method so that abnormal sound due to waveform deformation is not generated . Attack t.
