Tillverkas tyvärr inte längre.
8-kanalig micpreamp av svensk tillverkning.
Svenskbyggd(!) 8-kanals rackmonterad lågbrusig mic-preamp. DC-kopplad förutom de matchade plastfilm-ingångskondensatorerna och baserade på ett lågbrusigt klass A, matchat diferentialpars ingångssteg, följt av O/P-förstärkare med mycket lågt brus och distorsion.
XLR-anslutningar in och ut, 48V fantommatning, 20dB pad, HP-filter 12dB/oktav vid 100Hz, 60dB gain.
Tveklöst mest prisvärda preampen om man behöver ett ofärgat och lågbrusigt ljud!
