Manufacturer's Description from Roll

Are you dissatisfied with the harsh, sterile sound of your Digital Audio Workstation? Do individual tracks sound good while full mixes sound flat and lifeless? Are you having a hard time deciding between an API or a Neve console for creating lush analog mixes from your DAW? Are you unable to afford either one? Do you have a rack full of expensive vintage and esoteric microphone preamplifiers sitting unused at mixdown time? Perhaps the RMS216 Folcrom from Roll Music Studios can help you find the sonic glory you've been missing.

The Folcrom is a high quality passive mixer intended for multichannel analog summing of digital mixes. It uses no active circuitry and provides no gain or level controls. The idea is to control the level, panning, EQ, and effects sends of your mix from within the DAW, and send as many as 16 different tracks or submixes to a high quality multichannel outboard DAC which in turn feeds the Folcrom. You then perform only the summing in the analog domain. This enables you to maintain absolute repeatability from within your DAW.

Each of the Folcrom's input channels features a balanced connection on standard 8-channel DB25 connectors and a pair of pushbutton switches to assign that channel to the Left or Right output, neither, or both. The output of the Folcrom is a stereo pair of balanced, 150-ohm signals on XLR connectors and requires approximately 30-40dB of make-up gain (program dependent). This signal is ideally suited for feeding into an outboard microphone preamp of your choosing. The Folcrom is therefore able to assume a wide variety of tonal character dependent on your choice of amplifier. The Folcrom itself has an extremely simple, pure, and transparent signal path. The absence of faders, EQ, aux sends, pan knobs, or any other superfluous features allows for an entirely passive circuit. There are no amplifiers, ICs, transistors, capacitors, or transformers in the signal path whatsoever. The simplicity of the fully balanced, symmetrical signal path allows the use of no-compromise passive components for ultimate fidelity. The unit passes signals "from DC to daylight" without coloration. The "sound" of your mixer is up to you and your preamps. Chances are your mic preamps just sit there unused at mixdown time anyway, so why not put them to work?

By excluding the make-up gain amplifier from the Folcrom, we are able to provide an ultimate quality summing buss without compromise and at a price that's less than you paid for your car. At the same time, it provides a unique opportunity for wide tonal control by allowing you to choose your flavor of make-up gain. Put those old Telefunken or RCA tube preamps to work when you want super thick warmth; or plug into your Great River MP-2 when you need pristine clarity. What other analog console can give you so many options, in such a small space, and at such a reasonable price?

About Manufacturer

The name Roll Music Studios is an indication of our business and aesthetic philosophy regarding music and the effective production of it. Roll Music stems of course from Rock and Roll Music, which has been fairly popular in our community for a number of years. The name has been shortened at times to simply Rock Music, and we believe that dropping the word Roll coincided with a conspicuous deviation from the rhythmic principles which gave early Rock & Roll music much of its power. This may be a somewhat unorthodox position for us to hold, since Rock Music and its various sub-sub-genres such as Hard Rock and Punk Rock are widely believed to be founded on the raw power element of the driving Rock & Roll rhythms. We believe the real power of Rock & Roll music came from a more subtle, subversive polyrhythm that revealed its true animalistic, sexual origin.* We therefore adopted the name Roll Music in an effort not to reject the pounding, thrusting rhythm of Rock Music, but to reaffirm our commitment to the fluttering, fleeting side rhythms present in true Rock & Roll music.
