Six digital inputs, an analog RCA input, and balanced XLR and unbalanced RCA line outputs connect your headphones and speaker system through one component. A high-resolution touchscreen and included remote put volume, input selection, and digital filters within reach.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eBalanced headphone power\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe WANDLA HP’s fully-balanced composite IC headphone amplifier delivers 3.5W into 50Ω through its front-panel 4.4mm output. For single-ended headphones, the included 4.4mm-to-6.35mm adapter provides access to up to 1W into 50Ω. The headphone section offers a 122dB dynamic range, with output impedance rated at 1Ω balanced and 0.5Ω unbalanced.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eESS conversion with Ferrum engineering\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe ESS Sabre ES9038PRO DAC works with Ferrum’s proprietary current-to-voltage converter and an output stage informed by the development of the OOR headphone amplifier. USB-C and I2S support PCM up to 32-bit\/768kHz and native DSD512. The DAC section specifies THD of 0.00009% and unweighted THD+N of -115dB.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSERCE digital processing\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFerrum’s ARM-based SERCE platform handles incoming digital audio using the company’s own software.
