Dual Channel Audio Amplifier Board Hifi Fever Capacitor Discrete Tube Power Diy
Description:
Brand Name: Aiyima
-UPC2581V is a HiFi-level dual-channel pre-driver integrated circuit developed by NEC for S-ONY. There is no corresponding internal equivalent circuit, and there is no corresponding index or parameter. It is an integrated circuit used by S-ONY tens of thousands of amplifiers. ;
-The UPC2581V pre-driver contains two channels of input stage and voltage amplification stage. The internal twin transistor has excellent consistency and HiH level sound quality.
-The UPC2581V uses a classic circuit, which only contains the input stage and voltage amplification stage, does not contain the push stage, and has a low temperature. It does not need to add a heat sink to the UPC2581V, and the external circuit is more flexible.
Feature:
1. Using 718 thick tongs foot resistance. high quality.
2. Fever capacitor, fly in black gold capacitor. N-ichkon MUSE goddess capacitor (green) sound clear and low-frequency, compact and compact, medium-frequency texture, clean sound and clean. The layering is good, high-frequency gorgeous and smooth, high resolution,
3. S-akamoto O-MRON relay, combined with the classic UPC1237 protection circuit to prevent switching shock and DC output protection, protect the horn.
4. Working voltage: allowable range Dual AC18V - 32V.
5. Output power: Max 120W + 120W, impedance 4 to 8 ohms.
6. Board size: 155X92MM, heat sink size: 155X132X52MM
7. Two input sockets are compatible, blue and white three plugs and two ones for easy installation
8. Onboard dual-circuit insurance circuit.
