Noise reduction module, accessory for 80-8 tape recorder, bag, manual, 16 RCA cables, no warranty card. Known to be in good condition. This unit is priced on request depending on service required. $250 (Tested appears to work, minimal repair, clean up time is spent) - $400+ range (Full restoration everything repaired, all relays cleaned (there are 16 of them!!) tested, calibrated, etc. ) These are 30 years old, it is almost a requirement to really perfect. Once serviced correctly these are very reliable and great performing machines. We also do a modification in the circuit which reduces the circuit noise another 4 to 6 db and also reduces the crosstalk, simulsync, playback at high frequency by almost 10 db. A significant improvement. $160 for the modification.
*** We left the listing up because we repair these, and did have parts/units to sell. These were very interesting products for the era. The SP1 were very strident and difficult to mod or fix for modern use and now require very rare parts for any repairs. A better product that works in a similar way is the later version Aphex Aural Exciter type A, B, etc. Which has a much nicer sound, is more adjustable to be more euphonic 2nd harmonics enhancement device. Without a doubt, better for vocals and acoustic instruments. We also modify the Aphex to be more nuanced in their operation. However, we will attempt to fix your SP1 if need be, but tough to get parts. You are welcome to call.
With manual, 6 channel signal router, 6 in-2 out line mixer, 2 in-6 out line splitter, 6 in-6 out buffer amp, all 1/4" I/Os balanced, 1 rack space, each channel has Level and Balance/Pan, This is the older better built (more rugged) unit.
3 band (low/mid/hi) compressor/expander in nice condition with wood sides. Original version with individual board modules for VCA! Modified with 3 band controls and ground mods (no input gain mods). Low noise spec. This is the early version unit preferred by audiophiles.
In addition to proper cleaning and calibration we replace any off spec parts (which will happen naturally on a 30 year old device). The modification I do adds 3 newly installed front panel controls which allow for full adjustment of expansion vs. Compression of each low, middle, and high band. Although the ins/outs are RCA, the 3BX has no trouble handling +14 dbm. This device is probably the only 3 band expander/compressor available on the market. On a mix, one could expand the highs to zip up the clarity and reduce noise, while compressing the bass end to add thickness. Adjustment controls for dynamic range, threshold also increase the versatility
