        "content": "Which \u201cBehringer 18/20\u201d are you referring to? Probably the UMC1820 audio interface (18 inputs, 20 outputs). If so, here\u2019s what I found out about its outputs and whether they are truly balanced.\n\n---\n\n## What \u201cBalanced\u201d Means\n\n- Balanced audio output means two signal conductors (hot & cold) plus a ground. The hot and cold are equal but opposite in signal polarity. This helps cancel noise picked up along the cable.  \n- Some \u201cbalanced\u201d connections are actually *impedance-balanced* or *pseudo-balanced*. They don\u2019t carry inverted signal on the cold lead, only balance the impedance to help reject noise.  \n\n---\n\n## What the Specs Say\n\nFrom the manufacturer and retailer documents:\n\n- Behringer states that \u201cLine OUT 3\u201310 balanced \u00bc\u02ba TRS outputs\u201d ([manualslib.es](https://www.manualslib.es/manual/935385/Behringer-U-Phoria-Umc1820.html?utm_source=openai))  \n- Also, the \u201cMain OUT balanced \u00bc\u02ba TRS outputs\u201d are clearly labeled balanced. ([manualslib.es](https://www.manualslib.es/manual/935385/Behringer-U-Phoria-Umc1820.html?utm_source=openai))  \n- The spec sheet from Bhphotovideo confirms: \u201c10\u00d7 1/4\u02ba TRS line output\u201d and \u201c8\u00d7 1/4\u02ba balanced line outputs\u201d depending on exact output grouping. ([bhphotovideo.com](https://www.bhphotovideo.com/c/product/1250276-REG/behringer_u_phoria_umc1820_usb.html/overview?utm_source=openai))  \n\n---\n\n## But: True Balanced vs Impedance Balanced\n\nSome user reports suggest the UMC1820\u2019s balanced outputs might actually be *impedance-balanced* rather than fully differential (true balanced):\n\n- One user circled the idea that the UMC1820 outputs are impedance-balanced, meaning that while the connectors are TRS and the circuit attempts balance via impedance, it might not put out inverted signal on the \"cold\" leg. ([reddit.com](https://www.reddit.com/r/Behringer/comments/14f0fm1/does_the_umc1820_have_balanced_outputs/?utm_source=openai))  \n- This is relevant if you\u2019re plugging into gear that expects a true balanced input, or using long cable runs, or trying to eliminate noise hum entirely.\n\n---\n\n## Summary\n\n- Yes\u2014the Behringer UMC1820 has outputs labeled as \u201cbalanced.\u201d The TRS line outputs (Line Out 3-10 and Main Outs) are officially stated to be balanced. ([behringer.com](https://www.behringer.com/en/products/0805-aan?utm_source=openai))  \n- However, there\u2019s reason to believe they may only be impedance-balanced (= pseudo-balanced) rather than fully differential. That means under many conditions they will behave like balanced outputs, but may not reject noise as well as true balanced outputs in every scenario.\n\n---\n\nIf you like, I can check measurements/tests to see exactly how \u201cbalanced\u201d the UMC-1820\u2019s outputs are in practice (e.g. polarity, noise rejection) to help you decide for your setup."
