New 14-inch MacBook Pro and upgraded 16-inch MacBook
The Pro uses an improved headphone jack, and Apple says it adapts to low-impedance and high-impedance headphones, without the need for an external amplifier.On 14-inch and 16-inch MacBook
At the Pro conference, Apple mentioned how the improved audio features include an improved headphone jack. Now, the company has detailed what these amendments are and how they will benefit users.
“newMacBookPro models support the use of high-impedance headphones, “This is described in a new support document about improvements.” When you connect headphones with an impedance of less than 150 ohms, the headphone jack provides an effective value of up to 1.25 volts, but for impedance For 150 to 1k ohm headphones, the headphone jack provides 3 volts rms, which may eliminate the need for an external headphone amplifier.”
In addition to this impedance detection and adaptive voltage output, the new 3.5mm headphone jack also has “a built-in digital-to-analog converter” that supports a sampling rate of up to 96kHz, which means that users can enjoy high-fidelity, full-HD Audio”.
