WebOne way to maximize the effectiveness of audio headphones as a null detector is to connect them to the signal source through an impedance-matching transformer. Headphone speakers are typically low … Headphones with impedance greater than 100 ohms are typically older or professional studio specific designs. Pre-1990s receivers and pro audio equipment often used resistors to attenuate the speaker output power (wattage) to create a simple and inexpensive headphone circuit. These headphone … See more When describing impedance, there are several terms that you should aware of. When viewed as a simple electronic circuit, the impedance of the audio source may be written as … See more Impedance matchingis the interaction between the source impedance (the device the headphone is attached to) and the headphone … See more Obviously, a headphone driver is capable of reproducing a wide range of frequencies. A perfect driver would remain consistent across the … See more Sensitivity (or efficiency) is a measurement of headphone volume at a specific power rating. Headphone sensitivity is often measured at a specific frequency (1 kHz) at 1 mW of power. Sensitivity ratings are … See more

WebFeb 15, 2024 · If you decide to do that, while I don’t know what the unspecified output impedance of the preamp’s tape outputs is, to minimize the possibility of impedance incompatibilities I would suggest choosing a headphone amp having an input impedance of at least 47,000 ohms (47K). Regards,-- Al WebJun 1, 2024 · Use headphones with 16 Ω or more impdance. Put a 1.4:1 audio transformer between the D/A and the headphones. The D/A output will need to be 1.4x larger than before, but will see a 16 Ω load when 8 Ω headphones are connect to the output of the transformer.
