“ORIGIN” Single channel (mono) multi-function vacuum tube -and- solid state music recording system. Employs -both- solid-state HV-3 and vacuum tube M-2B microphone preamplifiers — selectable via the push of a button. Employs TCL vacuum tube -or- solid state opto-compressor/limiter, switch selectable. Employs NSEQ vacuum tube -or- solid state 4-band parametric equalizer, switch selectable. Offers vacuum tube -or- solid state line input gain, along with vacuum tube DI instrument input, vacuum tube -or- solid state de-esser, transformerless -or- transformer coupled inputs. Large Sifam true audio metering, compressor stereo link jack. More than 130 possible solid state and vacuum tube Oldproduct combinations in one box. Numerous input and output functions. Standard gloss black cosmetic. Unique platinum-crackle cosmetic option available. (“STT” = “Straight To Tape”).

Two channel vacuum tube parametric equalizer-and- two channel solid state parametric equalizer in the same chassis; selectable via the push of a button. Four bands of EQ per channel offering pristine musical accuracy via pure Class-A all discrete FET amplifiers -or-heightened euphonic musicality via pure Class-A all vacuum tube amplifiers. Sweeps all frequencies from 20 Hz to 25 kHz. Stepped end-band frequencies also included at 20, 34, 56, 100, 180, 270 Hz and 4.8, 5.8, 8.0, 10, 16, and 24 kHz. Switch selectable shelving or peaking responses. Boost and cut switch selectable +/- 20 dB or +/- 10 dB resolutions. Boost and cut employs 21-step detented controls. Sweep “Q” from 0.4 to 4.0. Any frequency band can be switch bypassed. Each channel can be switch bypassed. Entirely transformerless signal path on both topologies. “Quasi-Mastering” option (all-detented controls) available. Balanced input option available. Standard gloss black cosmetic. Unique platinum-crackle cosmetic option available.

“TWINCOM” Two channel vacuum tube opto-compressor/limiter -and- two channel solid state opto-compressor/limiter in the same chassis; selectable via the push of a button Offers pristine musical accuracy via pure Class-A all discrete FET amplifiers -or- enhanced euphonic character via pure Class-A vacuum tube amplifiers. Opto-electronic gain reduction with Attack ballistics of 2 mS to 80 mS, Compression Ratio of 1.4 : 1 to 30:1, and Release Time of 30 mS to 3.0 sec. Large illuminated side-by-side Sifam true audio level meters are centrally located. Illuminated switches select channel in/out, stereo link, meter GR/VU select, and Twin Topology. Entirely transformerless, entirely balanced signal path on both topologies front to back. “Quasi-Mastering” option (all-detented controls) available. Standard gloss black cosmetic. Unique platinum-crackle cosmetic option available.
