Proudly from our beginning, we at MANLEY LABS have been closely involved with numerous mastering facilities around the world. For these most demanding engineers in our industry, we have created specialised products such as our all-tube tape repro head amps, digital converters, high-powered vacuum tube monitor amplifiers, through to custom monitoring consoles, all the way up to complete facility design and installation.
The Mastering Version of the SLAM! incorporating detented and logable 1/2dB steps built with 1% metal film resistors on sealed gold-contact Grayhill switches is in full production.
You can read on the regular SLAM! page all the particulars about the limiters and the general gist of the SLAM! Keep reading on below for specific info about the Mastering Version of the SLAM!
Differences and Features, yes there are some differences and features:
First off: no microphone preamps. You mastering engineers certainly don't need those. The mic pre and input select switch are removed and the switches become dedicated "mode" switches one each for the ELOP and the FET limiters.
1) The ELOP limiter gets more Ratios - 10:1, 5:1, 3:1, 2:1 and something new called AutoHF which starts off as a 1.5:1 ratio and increases gradually to 10:1 for highs. This is something like a de-esser, and of course can work with the ELOP SC toggle at 200Hz for even more effect.
2) The FET limiters get new modes that are 50%, NORM, LP Lim, BOTH, and CLIP.
3) The LEFT blue erstwhile-"limit" button becomes a master stereo LIMIT bypass switch here in the Mastering Version. When it is not engaged, it becomes a true hard-wire bypass (This was not possible on the mic preamp regular version obviously).
4) The Right blue button becomes the DAC select switch (stereo).
5) The what-was-the-Phantom toggle on the back of the unit becomes the Unbalanced 1/4" jack input select in this new mastering version.
6) There are no pots on the faceplate of the Mastering Version of the SLAM! All of the knobs in the Mastering Version are discrete detented switches in mostly 1 dB steps, with some appropriate 1/2 dB and 2 dB steps, right where they should be.
More than that, we really like the way it works and sounds and we generally prefer it to the non-mastering version for stereo tracks. There is a lot less fiddling involved to maintain L/R balances and the new modes are subtle but fun. It is easy to make just about anything sound better.
