HPToy iOS/Android app was modified to get the switch for 3 output modes:\n1) Balanced - the same as PDv2 balanced 2.5mm TRRS up to 600mW/channel output\n2) Unbalanced - you can use that mode with E1DA 2.5/3.5mm adapter to drive your unbalanced headphones, however, power in that mode is lower vs Balanced mode\n3) Unbalanced Boost - the same as Unbalanced with full 600mW power but with some crossfeed effect. This is the price for the versatility of a single 2.5mm TRRS output\nAlso, PDv2.1 got the new USB audio bridge CT7601 Comtrue, instead of Cmedia which was far from ideal.\n\n\n\n\n\nSoft-start Function\nPDv2.1 has a soft-start function to avoid high inrush current, in fact, PDv2 may work with any Android phone without Y-splitter, if you wish to use such a power-hungry device with your phone.\n\n\n\n\n\nCompressor/Limiter\nThis function really useful for an open back planars to \"compensate\" ambient noise. And limiter keeps sound distortion-free at high volumes, also you can see the output clipping indication in the app e) Preset manager allows to save/load presets and export/import(email/skype/www etc) as well to share PowerDAC settings between users f)\n\n\n\n\n\nIntuitive Controllable Filters\n7 parametric EQs, left/right gestures control frequency, up/down gain, zoom in/out Q-factor. Also available LPF/HPF and APF for phase alignment and text form Biquad control just in case. Default standard configuration: DAC+2.5/3.5 Adapter+Type B to A Cable\n\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/E1DAPowerDACV2.1-2.jpg?v=1620385754","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/E1DAPowerDACV2.1-5.jpg?v=1620385754","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/E1DAPowerDACV2.1-6.jpg?v=1620385754","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/E1DAPowerDACV2.1-7.jpg?v=1620385754","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/E1DAPowerDACV2.1-3.jpg?v=1620385754"],"price":89.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.808Z"},"share_url":"https://firestarter.network/l/lst_59aryNxr","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
