HP Poly SHS 2692-01 PTT Amp High Gain LEMO FGG.2B.310 (REF SHS 1890)

Product Overview

AI-generated summary

At £152 ex-VAT, this HP/Poly “PTT amp” is one of those niche pieces that only makes sense if you’re already living in that ecosystem. It’s not the kind of accessory you buy “just in case” for general audio setups—high-gain PTT amplification is typically there to fix a specific problem in comms/dispatch/radio-style workflows (think clearer push-to-talk levels, consistent mic drive, and reducing the fiddly trial-and-error you get when levels aren’t matching). If you’re maintaining or upgrading an existing Poly/HP comms install that uses this style of LEMO interface, then it’s genuinely useful and good value compared to spending time diagnosing level/compatibility issues.

I wouldn’t buy it if you’re building a one-off conferencing or standard PC headset rig. The interface/intent is too specialised, and if your current hardware doesn’t require a dedicated gain stage with that particular connection style, you’ll just be paying for complexity you don’t need. In short: buy it if you’re replacing the exact missing/failed component in an existing compatible setup; skip it if you’re hoping it’ll be a universal “audio booster” for anything with a mic.
