TRIODE-TRX-2 MM⁄MC Tube Preamplifier

Description

Triode TRX-2
It is an upgraded product of TRX-1 preamplifier and is equipped with new functions such as analog playback circuit.
The TRX-1 is also succeeded by the 4-band equalizer that can finely control popular tones, which allows you to freely adjust the reverberation characteristics of the room to create an ideal audio room. Especially by adjusting the low-frequency characteristics that tend to be insufficient at night, it is possible to correct at low volume.
On the TRX-1, the 4-band equalizer can be turned on and off only with the remote control, but it can now be turned on and off with the LED switch on the front panel. The remote control function enables volume adjustment, input switching, mute, and 4-band equalizer ON/OFF, and the left and right balance can be adjusted on the front panel. For the rectifier circuit, we have adopted the well-established direct-heat rectifier PSV ONE WE274B to aim for attractive music playback.
