SPM4 mixes audio through 4 audio transformers specifically developed to achieve very low distortion and highly linear acoustic response. SPM4 provides the ability to mix the midrange\/woofer and tweeter channels coming from the amplifier and supply one single mid-high channel. The Ch1(L\/R) channels feature two inputs, one features an inverting input compared to Ch2 (L\/R) channels; the mixing process often gives better results when one of the two channels undergoes a 180° dephasing. SPM4 is especially recommended to extend the number of inputs of the Audison digital processors or amplifiers with built-in DSP because they feature a De-equalizer (De-Eq). In that case, any possible non-linear acoustic emissions due to the mixing of the pre-existing filtered channels are duly compensated.\u003c\/span\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":44104205009148,"sku":"SPM4","price":329.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/products\/spm4top.jpg?v=1675884757","url":"https:\/\/diycustoms.store\/products\/audison-spm4","provider":"diycustoms.store","version":"1.0","type":"link"}
