This is a high-fidelity stereo headphone amplifier designed by the Germans with NE5532. The NE5532 is a HI-FI preamplifier integrated circuit that is widely known by fans. Its excellent sound quality is highly praised by enthusiasts. Single power supply, but the actual listening effect is still very good, those who are interested may wish to give it a try.
The main parameters:
(1) Input impedance: 10K ohms
(2) Input level: 500mV-700mV
(3) Output impedance: 20-200 ohms
(4) Signal to noise ratio: 90dB
(5) Channel separation: >75dB
(6) Working power supply: 15V DC 200mA
The DC power meters are applicable to the measurement of DC distribution system. The transformation ratio of this series of meters is programmable. They supports digital input, relay output, analog output and communication functions. They provide a variety of different installation sizes and can directly replace the analog pointer ammeter.Some models also support DIN rail installation and can be used as DC multifunctional power meters.
