Aud­i­son bit One HD DSP

Pro­ces­sor Re­view

Pasmag (USA) - - TEST REPORT -

When it comes to the world of DSP pro­cess­ing for car au­dio, one of the lead­ing prod­ucts for the last seven years has been the Aud­i­son bit One. Be­cause Aud­i­son is so pas­sion­ate about au­dio and re­lent­lessly work­ing to­wards pro­duc­ing ever bet­ter gear, we now have the new bit One HD. The bit One HD presents a whole new era of DSP per­for­mance, with the im­ple­men­ta­tion of the most pow­er­ful DSP chipset avail­able. Op­er­at­ing at 450 MHz/32 bits, the new pro­ces­sor pro­vides the com­put­ing power to make the bit One HD ca­pa­ble of pro­cess­ing high res­o­lu­tion au­dio at 96 kHz/24 bits. The new flag­ship pro­ces­sor has a sug­gested re­tail price in the U.S. of around $1,700, and has al­ready gar­nered a cov­eted EISA award. care­fully be­cause this is a com­pli­cated de­vice. A guid­ing hand from your lo­cal Aud­i­son dealer wouldn't be a bad idea ei­ther. In ad­di­tion to the man­ual, a handy fold-out quick start sheet with sim­ple graph­i­cal in­struc­tions is also printed and en­closed. As soft­ware up­dates be­come avail­able, the bit One HD is eas­ily up­dat­able as well, thanks to its open plat­form de­sign.

When a prod­uct is this pow­er­ful, get­ting the in­stal­la­tion di­aled in is crit­i­cal.

Thanks to an au­to­mated cal­i­bra­tion process, the bit One HD can au­to­mat­i­cally ad­just and make corrections for up to 12 dif­fer­ent chan­nels of in­put, in­clud­ing fix­ing fac­tory equal­iza­tion and chan­nel de­lay is­sues. The unit comes with two dif­fer­ent discs (CD and DVD) that have spe­cially de­vel­oped au­dio setup tracks on them. Cal­i­brat­ing the in­put lev­els, cor­rect­ing the fac­tory EQ, and even com­pen­sat­ing for the chan­nel de­lays in OEM sys­tems is done au­to­mat­i­cally by sim­ply fol­low­ing some on-screen prompts. The soft­ware walks you through your sys­tem ar­chi­tec­ture, and even has pro­vi­sions if you hap­pen to be us­ing some pas­sive crossovers. While the guided process works fine and is very sim­ple to use, and I com­pletely un­der­stand why the in­put sen­si­tiv­ity setup process has been au­to­mated, I'm sort of old school and I would pre­fer the op­tion of set­ting it my­self. If you're like me, for­tu­nately you can manu-
