We think of it as a workhorse: the design focuses on high power delivery rather than a long list of features that push up the price. If you need an amplifier that simply gets on with the job, this is a sensible choice.\u003c\/p\u003e\n\u003cp\u003eConnections are where the QA400 earns its keep. Each channel takes a combo input that accepts both a 6.3mm jack and an XLR, plus RCA (phono) inputs, so you can feed it balanced or unbalanced signals to suit your setup. Outputs cover Speakon-style SPK terminals, 6.3mm jack and 4mm binding posts, giving you options whatever your speakers and cabling. Overheat and overload protection circuitry is built in, so the unit looks after itself under load.\u003c\/p\u003e\n\u003cp\u003eThe QA400 fits a standard 2U 19-inch rack, making it easy to add to an existing rig or fixed install. It runs on 110\/240Vac at 50\/60Hz through an IEC socket, so it works with typical UK mains. With THD of 0.25% and a signal to noise ratio (SNR) of 90dB, it holds up well for live sound, background music and general PA duties. It sits alongside the wider QA Series, so you can pick the power rating that matches your needs without changing the way you connect or mount the amplifier.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e6.80KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e88mm x 482mm x 270mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower rms @ 8 Ohms\u003c\/td\u003e\n\u003ctd\u003e2 x 70W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower rms @ 4 Ohms\u003c\/td\u003e\n\u003ctd\u003e2 x 100W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower max. @ 4 Ohms\u003c\/td\u003e\n\u003ctd\u003e2 x 200W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse rating\u003c\/td\u003e\n\u003ctd\u003eT5A (240V) \/ T10A (110V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e110\/240Vac, 50\/60Hz (IEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e0.25%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSNR\u003c\/td\u003e\n\u003ctd\u003e90dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003eCombo (6.3mm jack + XLR) and  RCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003eSPK, 6.3mm jack and 4mm binding posts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/172020UK_38d047f4-5a1b-419e-8d44-85add4c066c1.pdf?v=1784989345\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat inputs does the QA400 accept?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach channel has a combo input taking both a 6.3mm jack and an XLR, plus RCA (phono) inputs.
