Webb20 aug. 2024 · In addition to protection against constant voltage, the circuit provides a delay in connecting the speaker system. After applying the supply voltage, the relay does not turn on immediately, but after 2-3 seconds, this is necessary in order to avoid clicks in the columns when the amplifier is turned on. The supply voltage of the circuit is 12 volts. Webb7 apr. 2010 · A simple transistor based time delay circuit is used for attaining the purpose. The circuit is so connected to the existing amplifier that, when the amplifier is powered on the bridge D1 also gets powered through the amplifier’s power switch.

Webb30 apr. 2024 · I have D2 connected to the RLY's "normally closed" output, so when I turn on the switch, D2 also turns on, but it never turns off like I want it to. I thought the RC time constant would be 1 sec since C1*R2 = .001 * 1000 = 1, but using the setup below, the relay never engages. I used a multimeter to measure voltage drops across R2, RLY, and C1 ...
Webb18 aug. 2024 · You can increase the value of C2 to add more turn on delay. Q2 drives the relay that connects the output of the amplifier to speaker. When a DC offset is detected on the output, Q1 will turn on and will cause the Q2 to turn off and will deactivate the relay that connects the speaker to amplifier. Update: Corrected the orientation of D3. Webb13 apr. 2024 · Hi forum. I've made a simple 12 V 3 sec. delay relay, coupled to the headphone output of my Rogers Gomez NP-100v12 Amp. Here are photos of my NP-100v12 - 12AU7 / IRF510 Headphone Amp with Turn-on Delay. It can also be used for speaker-outputs for a power amplifier. The Takamisawa 12v relay i've used is a two …
WebbIt's a simple but very effective circuit that would work just as well with a mains transformer instead of the capacitive dropper. By inserting the 1n4001 diode between the diode bridge and the smoothing capacitor, we can derive the 100Hz post-rectifier waveform. This turns the first transistor on and off again 100 times a second.
