HA150 small preamplifier Use Manual

The HA150 is a small preamplifier with one input and two outputs, such as a vinyl record player turntable and other devices can only output low level RIAA signals, however, most audio devices can only handle line level signals, that is, between the turntable and the audio device (mixer, power amplifier or headphones or recording equipment), the HA150 is used to re-amplify the signal.

Connection method:

 

1. The analog output interfaces such as record player/computer /DVD correspond to the audio input ports of the RCA Lotus left and right channels of the HA150 device.
2. The HA150 device RCA Lotus left and right channel audio output outlet or 6.35 audio output outlet is connected to the wired headset or power amplifier or active speaker, and the corresponding adjustment mode of the two devices is its own.
3. Connect to the power supply (select the output voltage 12V 1A charger)
