Product Details:
The fully balanced circuit structure and circuit principle diagram are as follows: From the output port of the sound source device to the speaker, the entire signal is transmitted in differential mode, completely suppressing induced noise. Considering that many front-end devices only have RCA single end signal output, we have also designed a set of RCA interface inputs, which can switch between single end RCA and balanced XLR by controlling the relay through toggle switches.
Double parallel structure: The cold end and hot end are respectively driven by two chips in parallel, with four LM1875 chips per channel, which can easily drive speakers of 4~8 ohms.
Dual mono construction: The two channels are powered by two transformers respectively, and the chassis is grounded at one point at the volume potentiometer (the only intersection point of the two channels). Two channels do not affect each other, completely eliminating the possibility of cross-talk between two channels, greatly improving sound separation, accurate sound image positioning, and stronger three-dimensional sense.
Use 2PCS high-quality A-core 100W power transformer.
Use 4pcs LM1875T chips and 2pcs NE5532 amplifiers per channel.
Use Panasonic FC series decoupling capacitors and ELNA CE-BP series audio capacitors coupling capacitors. Main filter ELNA 8200uf/35V capacitor.
Use ALPS potentiometers imported from Japan.
Use UPC1237+Omron relay speaker protection circuit, effectively eliminating the impact sound of on/off and DC output protection function, making your speaker safer.
Use American CMC RCA terminals and pure copper crystal terminals.
Use an all aluminum chassis.
