The BIAS control can be used to adjust how long the amplifier operates in pure Class A. With a lower BIAS control, the amplifier works better in controlling treble and midrange. The sound image is more three-dimensional, the tone is warmer and the nuances are more accurate. With a higher control, you get better performance in the bass range. More authority and power. Thanks to the very robust dual power supply, the reproduction is accurate and the sound is powerful.\u003cbr\u003e \u003cbr\u003eMundorf capacitors and Burr\u0026amp;Brown operational amplifiers are guaranteed to be the highest quality parts available for automotive use.\u003cbr\u003e\u003cbr\u003e The amplifier is stable up to 1 ohm loads.\u003cbr\u003e\u003cbr\u003e \u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e - 4 channel amplifier\u003cbr\u003e - 4x 125 W @ 4 ohm, 4x 225 W @ 2 ohm, 4x 350 W @ 1 Ohm, RMS\u003cbr\u003e - 2x 450 W @ 4 Ohm, 2x 700 W @ 2 Ohm, Bridged RMS\u003cbr\u003e - stable to 1 ohm stereo, 2 ohm bridged\u003cbr\u003e - class AB\u003cbr\u003e - adjustable BIAS\u003cbr\u003e - Mundorf capacitors\u003cbr\u003e - Burr-Brown OPA2134PA operational amplifier\u003cbr\u003e - lowpass\u0026amp;highpass filters 20 – 400 Hz \/ 200 – 4000 Hz\u003cbr\u003e - THD 0.01%\u003cbr\u003e - damping factor 220\u003cbr\u003e - response 10 - 50,000 Hz\u003cbr\u003e - dimensions 222 x 61 x 420 mm.\u003c\/b\u003e","brand":"Ground Zero","offers":[{"title":"Default Title","offer_id":56759203758455,"sku":"GZPA 4SQ","price":1199.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/GZPA-4SQ-2_986cc9eb-d1f0-4740-9e33-1dcef0d10105.jpg?v=1771442407","url":"https:\/\/hifikaupat.fi\/en\/products\/ground-zero-gzpa-4sq","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
