All of the modules from ROLL MUSIC feature a unique two-stage tube amplifier based on the ECC832 (12DW7) dual triode which provides both voltage gain and output drive. The amplifier provides makeup gain after a buttery smooth passive 2-band tone control with a selectable high band (16k Hz and 8 kHz), fixed low band (150 Hz), and switchable high pass filter (100 Hz). The amplifier is powered by ROLL MUSIC’s proprietary high-voltage internal voltage booster, which produces more than 200 V internally from the ±16 V and +48 V rails available in a standard 500-series powered enclosure.\u003c\/p\u003e","brand":"Roll Music Systems","offers":[{"title":"Default Title","offer_id":44450513158247,"sku":"130483","price":799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/roll-music-rmsb5t_130483_1_0d219e7b-e757-4b24-a49d-1fa4eb5703ac.jpg?v=1787093365","url":"https:\/\/vintageking.com\/products\/roll-music-systems-rmsb5t-vacbax-500-series-tube-equalizer","provider":"Vintage King","version":"1.0","type":"link"}
