The LM833 is a dual general purpose operational amplifier designed with particular emphasis on performance in audio systems. This dual amplifier IC utilizes new circuit and processing techniques to deliver low noise, high speed and wide bandwidth without increasing external components or decreasing stability. The LM833 is internally compensated for all closed loop gains and is therefore optimized for all preamp and high level stages in PCM and HiFi systems. The LM833NG is pin-for-pin compatible with industry standard dual operational amplifiers.Juried Engineering Products are shipped in ESD Sa... [Read More]
Quick tips:1. Please plug the power cord into the amp THEN the wall, plug the audio cables into amp THEN switch on.Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.Parameter: 1. Power supply range: 12v-32v; 2. THD: ≤ 0.04%; 3. Frequency Range: 20Hz - 120Hz (±1 dB); ... [Read More]
