HP Poly SHS 2177-02 PTT Amp LEMO FGG.2B.310 and Wiring Options (REF SHS 1890) TAA

Product Overview

AI-generated summary

For £152 ex-VAT, this HP Poly “PTT amp” kit with the LEMO FGG.2B.310 connector is the sort of thing you buy when you *already know you’re missing one specific piece* in a dispatch-style or in-room conference setup. It’s not a general-purpose upgrade; it’s basically the fix for a particular connectivity/triggering path (push-to-talk and wiring integration) referenced by the SHS 1890 family. If your install plan matches that reference and you need reliable PTT amplification/conditioning with the correct connector option, it’s decent value versus paying for labour to improvise or source the wrong leads.

I wouldn’t buy it for “just in case,” and I wouldn’t buy it as a substitute for a proper audio/endpoint solution. If you’re building a meeting room from scratch, there are usually cheaper, more straightforward approaches (or you’ll need additional parts anyway), and you risk ending up with an incompatible connector/wiring expectation that only shows up after the installer’s already on site. In short: it’s a sensible, cost-effective part for integrators and IT teams standardising a known Poly SHS 1890 workflow—less sensible for anyone guessing or hoping it’ll “probably work.” If you tell me what endpoint/mic system you’re integrating and how the PTT is being triggered, I can sanity-check whether this is the right type of purchase.
