HP Poly SHS 2470-03 PTT Amp LEMO FGG.2B.310 4.02K OHM ADD (REF SHS 1890) TAA

Product Overview

AI-generated summary

This is the kind of niche audio part you only buy when you’re already sure what it’s replacing. The “PTT amp”/LEMO FGG.2B style setup screams intercom/radio headsets and field comms rather than everyday meeting-room audio, and at £173.05 ex‑VAT it’s not “cheap fix” territory. In other words: if you’ve got an HP/Poly SHS system and you’re getting a specific failure (low level, distorted mic/press‑to‑talk performance, intermittent switching) and you’ve matched the exact reference, this will likely be a straightforward, no-drama repair and better value than trial-and-error replacements.

Who should buy it: UK businesses maintaining Poly/HP comms hardware in roles like security, control rooms, broadcast/production support, or mobile/temporary comms where SHS accessories are part of a standard fleet. Why buy: correct fitment and reliability—these adapters/modules matter because “almost compatible” parts can lead to flaky PTT behaviour or degraded audio paths. Why not: if you’re just trying to improve general conferencing audio, there are usually more cost-effective, purpose-built upgrades; and if you can’t confidently identify it as the exact replacement for your specific SHS configuration, the risk of wasting time and money is real.

If you tell me your exact SHS model and what problem you’re seeing (PTT not triggering vs mic audio too quiet vs hiss/distortion), I can give a firmer “yes buy” or “don’t” based on typical fault patterns.
