6.35 mm Headphone Output
6.35 mm Headphone Output counts the full-size TRS headphone jacks provided by the amplifier.
A conventional stereo TRS jack uses contacts for left, right and a shared return. It is often called a quarter-inch headphone output. This count is separate from smaller headphone jacks, balanced headphone sockets and line outputs intended for another amplifier.

Check the headphone’s plug and the amplifier’s permitted load before connecting it. A correctly wired adapter can change plug size, but physical fit alone does not establish the required output level or suitability for a particular headphone. Start at a low volume when changing headphones or outputs.
More than one jack may provide different operating ranges or share the same signal and control. Confirm whether simultaneous use is supported and whether it changes the available output. The jack count does not state power, noise, output impedance or independent channel control; those are separate specifications needed to understand the amplifier’s behaviour.
