Amplifier signal

set2: 1 x 600W boost constant current module + 1 x Amplifier Board Small size design, BTL output, the maximum output 100w, can drive 2 ohm speakers, be balanced (differential) input, external heat sink chip work more stable. Signal input mode can be selected according to the following two needs: Balanced input signal (differential): Signal + Signal -, GND (ground). Unbalanced inputs (single-ended): - end and GND (ground) short circuit, the signal input from the + terminal. 3300 / 25V filter capacitor The output voltage regulation: 1. adjust the CV-ADJ potentiometer, according to your or LED, the output voltage is set to the voltage you need. Clockwise voltage is small, counterclockwise adjustable. 2. clockwise CC-ADJ potentiometer about 20 laps, the output current is set to a minimum, connected to the LED, CC-ADJ potentiometer to the required current. For charg, put the after the end of the, then receive the output, adjust the CC-ADJ to the current you need, (for charg must be used when the is fully charged, because the left The more charge, the smaller the charge current.

XH-A302 Bluetooth amplifier board adopts amplifier chip with high-fidelity stereo sound quality; supports Bluetooth and AUX audio input; amplifier is equipped with Bluetooth 5.0 high-speed transmission, and the effective transmission distance of Bluetooth is 20 meters for unobstructed connection, (depending on personal mobile phone Bluetooth configuration, The signal strength is different, the transmission distance will also be different). The amplifier input is DC12-24V, with dual-channel output, the output impedance is 4-8Ω, and the maximum is 50W*2; the on-board function buttons can freely adjust the volume, switch songs, and select the input mode.

Onkyo tx-sa 606x Dolby TrueHD is Dolby’s next-generation lossless technology developed for high-definition disc-based media. DTS-HD (DTS-HD Master Audio™) DTS-HD Master Audio™ is capable of delivering audio that is bit-for-bit identical to the studio master. WRAT (Wide Range Amplifier Technology) WRAT is based around a low negative-feedback circuit topology that works to reduce signal noise and distortion across the frequency range. CinemaFILTER™ The tonal balance of a film soundtrack designed for a commercial theater will be edgy and bright when played back over audio equipment in your home. We have developed our own solution that restores the correct tonal balance of a movie soundtrack in the smaller environs of your home theater. 450 watts per ch 185 X 7 110 ac volts
