This allows the amplifier to be used with both very sensitive in-ear monitors and power-hungry headphones.\u003c\/p\u003e\n\u003cp\u003eWhen using the balanced input, the PA10 achieves an output voltage of \u003cstrong\u003eup to 6.2 Vrms\u003c\/strong\u003e, enabling powerful and controlled reproduction.\u003c\/p\u003e\n\u003ch2\u003eTrue Balanced Design with 4.4 mm Connection\u003c\/h2\u003e\n\u003cp\u003eMany portable amplifiers internally convert an unbalanced signal into a balanced signal. The \u003cstrong\u003ePA10\u003c\/strong\u003e takes a different approach and offers \u003cstrong\u003etrue balanced signal routing via 4.4 mm input and output\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThis keeps the signal completely balanced throughout processing, which \u003cstrong\u003eminimizes signal loss and enables higher output power\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eAdditionally, \u003cstrong\u003e3.5 mm inputs and outputs\u003c\/strong\u003e are available for unbalanced connections.\u003c\/p\u003e\n\u003ch2\u003eHardware Crossfeed for More Natural Listening\u003c\/h2\u003e\n\u003cp\u003eThe integrated \u003cstrong\u003ehardware crossfeed\u003c\/strong\u003e mixes a small portion of the left and right channels in a controlled manner. This technique can make the perception of the stereo soundstage feel more natural and reduces the extreme channel separation often found in headphones.\u003c\/p\u003e\n\u003ch2\u003eDesign and Portability\u003c\/h2\u003e\n\u003cp\u003eThe PA10 adopts Astell\u0026amp;Kern's characteristic \u003cstrong\u003eSLOPE design language\u003c\/strong\u003e, which is characterized by striking lines and high-quality craftsmanship.
