It works with most standard hearing aids and suits public and commercial buildings where clear sound matters. The unit fits a standard 19\" rack, so it sits neatly alongside other equipment in an installation.\u003c\/p\u003e\n\u003cp\u003eThree mic\/line channels each have their own phantom power switch and mic\/line level switch, so you can connect a mix of microphones and line sources. Front panel controls are adjusted with a screwdriver, covering channel volume, bass, treble and loop current level. These tamper proof controls help keep settings fixed once the system is set up. Channel 1 can be given priority, which is handy for announcements over other audio. Adjustable metal loss correction lets you compensate for metalwork in the building that would otherwise affect loop performance.\u003c\/p\u003e\n\u003cp\u003eA peak current LED shows when the loop is running near its limit, and alarm contacts allow a built-in siren to sound if needed. The amplifier runs from 110\/240Vac at 50\/60Hz through an IEC connection. Frequency response is 50Hz to 5kHz (±3dB), with line input sensitivity of -6dBu into 6k Ohms and mic sensitivity of -56dBu into 2k Ohms. Signal to noise ratio is 75dB on line inputs and 60dB on mic inputs, with THD below 1%. Note that a hearing loop is also known as an induction loop or audio induction loop, and the same amplifier is often called a loop driver in North American listings.\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\u003e4.22KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e483mm x 235mm x 88mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eArea coverage\u003c\/td\u003e\n\u003ctd\u003e600m² max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse\u003c\/td\u003e\n\u003ctd\u003eT2A 250V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRack height\u003c\/td\u003e\n\u003ctd\u003e2U\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\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e50Hz - 5kHz (±3dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity : line\u003c\/td\u003e\n\u003ctd\u003e-6dBu\/6k Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity : mic\u003c\/td\u003e\n\u003ctd\u003e-56dBu\/2k Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal to noise ratio\u003c\/td\u003e\n\u003ctd\u003e75dB (line), 60dB (mic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;1%\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\/952867UK_bbd9c3d3-d864-40ee-b1d7-90a8b5b889ab.pdf?v=1785056505\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many inputs does the LA-600 mkII have?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt has three mic\/line channels, each with its own phantom power and mic\/line level switch, so you can mix microphones and line sources.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it rack mountable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
