        "content": "If you're trying to identify which Bryston 5-channel power amplifier you have, here\u2019s what the sighted person should check and where to look. Bryston amps almost always have identifying labels in consistent places, and those labels will include the **model number**, **serial number**, and other useful info.\n\n---\n\n### \u2705 Places to look for the model number\n\n1. **Rear panel**  \n   - Look closely at the back of the amplifier. There is usually a **label or plate** near the power inlet (where the AC cord plugs in) that includes the model number, serial number, and electrical ratings.  \n   - This label is sometimes called a *data plate*, *rating label*, or simply *nameplate*.  \n   - If you see something that says \u201cModel,\u201d \u201cModel No.,\u201d \u201cMod,\u201d or things like \u201cBryston 9B SST\u201d or \u201c9B-THX,\u201d that\u2019s likely it.\n\n2. **Bottom of the unit**  \n   - If nothing visible on the back, flip or tip the amplifier (safely, using two people if needed) and check the bottom panel. Bryston sometimes places the full specifications label there.\n\n3. **Front panel width and style** (less precise, but may help narrow it down)  \n   - Bryston had different widths: some models are 19-inch rack width, some 17-inch consumer width.  \n   - The appearance of the front panel (color, LED lights, input selector switches) may hint at whether it\u2019s an older model (such as \u201cST\u201d series) or a newer one (such as \u201cSST,\u201d \u201cSST2,\u201d or THX versions).  \n   - For example: their **9B SST** is a 5-channel model with one chassis, and each channel has its own LED on the front. ([studiocare.com](https://studiocare.com/products/bryston-9b-sst-thx-5ch-multi-channel-amplifier-5-x-140-watt-rms?utm_source=openai))  \n   - The **9B-THX** is another 5-channel model, and its specifications (power per channel, etc.) match the 5-channel Bryston class of amps. ([stereophile.com](https://www.stereophile.com/content/bryston-9b-thx-five-channel-power-amplifier-specifications?utm_source=openai))\n\n---\n\n### \ud83d\udee0 What to tell your sighted helper\n\nAsk them to describe or report:\n\n- What text is on the label by the power cord input. Especially phrases like \u201cModel:\u201d or \u201cModel No.:\u201d\n- Any numbers like \u201c9B SST,\u201d \u201c9B-THX,\u201d \u201c5B,\u201d etc.\n- The voltage rating (sometimes helps date or identify). For example if it says 120V / 230V etc.\n- Whether there are five LEDs on front panel (for channel indicators).\n- Any switches labeled \u201cBalanced / Single-Ended,\u201d or input types such as XLR vs RCA.\n- Any serial number\u2014they usually also print the model name near the serial number.\n\n---\n\nIf you like, you can have your helper send me the text they read, and I\u2019ll help you identify exactly which Bryston model it is."
