JLM AUDIO Langevin AM16 Rack Case

Features

  • Custom AM16 1 unit high Rack Case with New  Laser Printing. Laser turns black anodizing white so marking can not be scratched off. Automatic 85v to 265v Switchmode power supply for +24v & 48v rails. IEC removable power cord and Gold Neutrik XLR inputs and outputs on rear panel  1 to 4 AM16 can be fitted to rack and laser writing changed to match. Each Mic Pre has switchable 48v, Phase, High Gain and 45dB variable input PAD pot (Marked as output on this version).

 

JLM AUDIO MCI Channel Rack Case

Features

  • Cut down MCI 400 Channel strip in 1 unit high Rack Case with New Laser Printed front panel. Channel 4 Mic Pre and EQ are the original from the Channel Strip but Mic Pre 1 to 3 are made by using the spare MCI opamps still on the main MCI PCB and our JLM Mini Transformers to make three extra Mic Pre amps with 60dB of gain and 48v, PAD, PHASE Switches where added to all four Mic Pre's. The unit is run from a external 24vac 1amp transformer which generates +/-24v and 48v internally.
JLM AUDIO Racked AWA Dual Channel Strips

Features

  • Road Case with 2 pairs of AWA Mic Pre and EQ. These are like AWA versions of the 1073 Neve but running on a higher voltage rail. These modules are rare. The input transformers are so large that they are the full width of the dual module which is obviously why they are made in pairs. We have added the output faders which work as 10dB trims normally or full fade to -70dB when the pot has its inbuilt switch pulled to the out position. Unit runs from +30v & 48v Switchmode power supply. These things sound great and have fatter low end that the Neve 1073. The EQ is very good with only the treble control needing its frequency shifted to make it more useable.  To get these modules working properly they need a lot of recapping and switch & pot cleaning and replacing. Also the modules are only unbalanced out with the external amp PCB and external Output Transformer. We use one of our unbalance to balanced modules with a new laser cut rear panel with XLR in & outs and TRS insert which screw straight on to the rear of the module. 
JLM AUDIO Pultec Road Case

Features

  • Custom Road Case with mounted Micro 240v to 110v stepdown transformer and XLR & TRS inputs and outputs. Pultec had tube rectifier go short circuit and destroyed the main filter capacitors which were internally replaced.  Replaced all tubes due to micro phonics and loss of output of 12AU7. Used 5814 Military Spec version of 12AU7 tube. Cleaned noisy original pots by opening rear metal caps and using CAIG pot cleaner and clean switches with CAIG switch cleaner. Unit tested as good as new with Flat 10Hz to 40kHz  at -1dB. THD less than 0.05% and Signal to noise greater than 90dB. Road Case was kept as compact and light as possible as the Pultec is for hire. Front panel came up like new with a real mirror finish but took a lot of cleaning work due to very old paper tape stuck on the front that had gone rock hard.

Hey Joe (there's a song in there),

Pres are fab. Love the top end, especially on guitars. Have just finished Lyall Adonis' debut album and I really put them through their paces. Some string sessions at my place with a pair of Oktava M012a condensor mics and piano recordings with same set up. I insert my TLA stereo valve compressor across it and it sounds fab. Used McCormack's Line 6 combo stereo direct into pres for some e/guitar tracks and that's when you hear some classic 70s guitar tone. You really get back what you put in. They're very true with that extra something. Very flexible gain structure as well. The line level pad is great for loading in samples and stuff from CDs and the hi gain is excellent for mics like my Sennheiser MD441U3 which is quiet as a ribbon mic. I did all the vocals with a 50s Neumann U-47 (the Sinatra one) and no EQ. Beautiful, warm as toast. I've got the pres and compressor in a roadcase and I've been taking them into studios, very portable. I dug out a whole lot of 70s drum loops I have on file (Stevie Wonder, Al Green, Shuggy Otis etc) and tweaked them through Q8s for a bit of sparkle and re-laid them on my portable DAT. I use 'em a lot in my solo shows and now they sound more THERE! Will try and send photo units in case.

JLM Audio Kaoss Pad Control Box

Features

  • Made for Brisbane band George this stomp box sends either Tyrone, Katie or Both Vocals to a Kaoss Pad.
