Web22 Apr 2024 · To calculate the output voltage after the matching circuit, we need to know the ratio of impedance, in our case, 1500 Ω/75 Ω=20. The voltage ratio (like turns ratio in transformers) is equal to the square root of the impedance ratio, so √20≈8.7. This means that the output voltage will be 8.7 times bigger, so it will be equal to 8.7 mV. Web14 Feb 2024 · HA-300MK2 offers two balanced headphone outputs: 4.4mm and XLR4 and we have optimize these two headphone outputs separately.

WebThe transformer should ensure there is enough voltage and current (power) to drive the headphones. The ratio of the transformer and the impedance of the headphones will determine the reflected load seen by the valve. It does not matter if the headphones see a reflected impedance of the valve which is lower than the headphone impedance. http://kearman.com/bentongue/xtalset/1nlxtlsd/1nlxtlsd.html tijani condo
