HP Poly SHS 2470-08 PTT Amp LEMO FGG.2B.310 2.67K OHM ADD (REF SHS 1890)

Product Overview

AI-generated summary

At £173.05 ex-VAT, this kind of HP Poly SHS/PTT amplifier “add” module is only really good value if you already live in the same ecosystem—i.e., you’re building or maintaining a specific Poly headset/comm setup and you need that exact LEMO/impedance pairing to make the PTT work properly. In real-world reseller terms: these parts are rarely impulse buys, and they’re usually purchased to fix a workflow (bad call behaviour, wrong audio path, non-functional PTT) rather than to “upgrade” anything for a new deployment.

Who should buy: AV/UC integrators and estates/operations teams standardising on Poly SHS hardware, with spares stocked so engineers can swap components fast without redesigning the cabling/audio chain. Who should *not*: anyone expecting a generic PTT/audio accessory that will work across random radios or headset ranges. If you don’t have the reference model and the correct connector/impedance context, you risk paying for the wrong module—and then it turns into downtime plus returns/rework, which wipes out the seemingly reasonable price.

If you can confirm it matches your existing SHS 1890 reference setup, it’s a sensible, maintainable spare. If not, I’d pause and validate compatibility first—because with niche comms accessories, “almost right” is still the wrong one.
