• Output power: 100W+100W (Vcc = 36 V, RL = 6Ω, THD: 10%); Output power: 80W+80W (Vcc = 34 V, RL = 8Ω, THD: 10%); High efficiency: 90%.
• Wide range single power supply: 15-34VDC(recommended 24V), differential inputs minimize common-mode noise.
• Applicable speaker impedance: 8 ohm best(4 ohm or 6 ohm also works); Four fixed gain settings available: 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB.
• With standby, mute features: short the points shown on pictures to be standby or mute, also can be vacant; With short-circuit protection, over temperature protection.

Mode:

• The TDA7498 has three kinds of modes: standby, mute and normal working mode(you can set the mode by shorting the pins shown on pictures).
• Standby mode: all circuits closed, at a low power state;
• Mute mode: all input signals connects ground, the duty cycle of forward/backward PWM output signal is 50%;
• Normal working mode: the amplifier works normally.

Package Includes:

• 1 x TDA7498 Amplifier Board
