Vintage 1970's Opamp Labs 10x4 Sidecar Recording Console Mixer Quad Eight Langevin

Up for sale is a Opamp Labs 10X4 recording console sidecar that has recently been serviced, fully tested, and is in excellent functional condition.  This sidecar is in excellent cosmetic condition with the exception of some defects in the vinyl armrest and wood veneer (see photos).

10x4 Sidecar
(10) 360BM Microphone Preamps
(10) 325EQ Equalizers (Inductor based, two band, stepped frequency selection)
(10) Line inputs (unbalanced inputs)
4 echo sends per channel, pre/post selectable
4 busses with UTC A-22 output transformers
4 echo returns
Direct outs on each channel through 5 pin XLR multipin connectors (wiring not included)
External rackmount +/-24V Power One linear power supply

Dimensions: 20.5"x30"x13"

The buss output levels are controlled through the four grey knobs on the right hand side of the console. The individual pan knobs are not connected for channels 1-6, so mixing is only Left/Right/Center through the four buss assign switches. The pan knobs are present and can be connected if you need individual pan controls for each channel.

This Opamp Labs desk sounds excellent and is on par with any vintage console on the market including any discrete API, NEVE, Quad Eight, Electrodyne, Sphere or Spectra Sonics console from the same era. The console runs at +/-24VDC and has more headroom than an API console. All the EQ's use inductors giving the EQ a Pultec/Quad Eight smoothness not found in later IC chip designs. The microphone preamps sound punchy and full like a 1970's Quad Eight. According to Bob Olhsson of Motown fame: "Some of arguably the best sounding mixes of the 1970s (if not of all time) were made using the Opamp Labs-based console in Armin Steiner's Sound Labs mix room." This console is one of the rare Opamp Labs consoles built at the Opamp Labs factory by Bel Losmandy in Los Angeles, CA. Included in this listing is a link to a track recorded few years ago with an identical 20 channel Opamp Labs desk to 2" tape. 

The console has been fully restored, fully recapped, cleaned and is in excellent condition. Since the photos the fader knobs have been replaced with all new matching Opamp Labs red knobs. Although this console has been restored and has been in daily use, it's almost 40 years old so if you purchase the console I'd suggest being technically inclined or having the resource of someone who is at your disposal upon delivery to help you use and set up the console appropriately. That said, maintenance on this console is easy - if there's ever a problem with a channel you just swap out the opamps with a spare and you're back to recording. All the opamp modules used in the console are still for sale via Opamp Labs in LA so I doubt you'll ever have anything that can't be handled quickly and cheaply.

All consoles for sale in our shop are tested with an Audio Precision audio analyzer prior to shipping for SN ratio, phase, THD, and frequency response. Feel free to contact me with any questions. Thank you!
