Features: pure resistance circuit, fixed input resistance, no noise, encoder + MCU control data, no sound size jump. Encoder / remote control volume control, sound source selection.
The volume limit protection can be set i. No higher than the value you set. Four channel input selection, two channel output selection and simultaneous output.
(automatic memory after selection) With remote control switch other equipment functions, such as front stage, power amplifier, etc. Volume progressive function (there are many modes to choose when the volume is turned on). Volume, input selection and output selection all have automatic memory function.
The balanced volume control system can be realized by the combination of two volume relay boards and two sound source switching boards, that is, one board is used for the balance control of one channel. (we also can provide 110V version) Volume board resistance : 10K 50K 100K for choose Display text color: default is Red. 1 set × Remote control volume control board (as the picture shows). The remote not included battery!
