The Power Amplifier must use a big power supply schema, due to great sound must also be supported with power (power supply) that great anyway. In the power amplifier 1000W (500W (L) and 500W (R) can work if driven by transformers least 10A. Diode bridge and Electrolite - capacitor (elco) must have a value too big. Average power amplifier can work if given the power consumption of the transformer between 2x24V to 2x80V, or more.
Indeed, the power amplifier can reach 40kg weight. But now some products speaker / Power Amplifier system known already implemented switching power supply with electronic methods. imagine if there is an active speaker / power amplifier transformer that uses ordinary (conventional), weighing up to 40 kg, but the active speaker / power amplifier system that uses switching power supplies only 20kg.
Ok, we return to the basic power supply of conventional systems. In the big power supply to the power amplifier used transformers worth between 5-30A and voltage 24-80V.
Bridge diode and elco have big capacity. Bridge diode adapted to the size of transformers, ranging elco 2x4.700uF to 2x10.000uF with voltage 63-100V. Used to filter capacitor 100nF. The power supply system using symmetrical power supply.
sometimes equipped with dual output transformers are symmetrical, ie the first 2x24V10A secondary, secondary and two 2x15V 1A, for example.
the second secondary (2x15V) used for pre amp Amplifier OP. TRANSFORMER CT connection is usually connected to the grounding (box).
but do not directly connect the grounding cable to the CT, because it will cause hum. Wiring must be correct, the wiring system distributed by the regulator power supply to each termauk to grounding equipment.
