FMR Audio Really Nice Compressor RNC 1773
The FMR Audio Really Nice Compressor, or "RNC" as it is lovingly known, draws a thick line in the sand between what is "cheap" and what is simply "inexpensive." This tiny little stereo workhorse, originally introduced in the late 1990s, has found its place in both weekend-warrior bedroom studios and top control rooms thanks to its transparent compression and compact footprint. It would be a steal at three times the price, and should make a number of higher-cost compressors blush and get back to the gym. - 6
Rupert Neve Designs Portico 542 500 Series Tape Emulator Module
The Rupert Neve Designs 542 Tape Emulator, a 500 Series adaptation of the popular RND Portico 5042, gives you all the thick tone and pleasing saturation of using a great tape machine.

Shadow Hills Dual Vandergraph 500 Series Stereo Compressor Module
The Shadow Hills Dual Vandergraph is a Class-A discrete stereo 500 Series compressor with topological ties to the behemoth Shadow Hills Mastering Compressor. This versatile module sounds thick as a brick, even before inviting any compression to the party. When it's time to start digging in, four switchable ratios go from gentle to aggressive while the sidechain filter section of the Optograph sits on the opposite side. Simple threshold and output gain controls are all you need to worry about to get your stereo mixes or groups under control. While the Dual Vandergraph may lack attack and release controls, each ratio has its own time constants to give you a range of sounds from fast and punchy to slow and gooey. Use the gentler ratios across an entire mix to give your track a bit of glue and polish, or strap it across a drum buss and and absolutely pummel it for explosive pumping sounds. To sum it up, if you've got two empty spaces 500 Series frame, you should probably have a Dual Vandergraph. - 69
Empirical Labs EL-9 Mike-E Preamp / Compressor
The Empirical Labs EL-9 Mike-E is a digitally-controlled combination microphone preamp / direct box / compressor. The compressor section includes a saturation circuit to warm up digital signals. - 70
Urei 1178 Stereo Peak Limiter
The Urei 1178 is a stereo peak limiter which is similar to two 1176 Rev H in a single 2U enclosure.
It lacks the Class-A amplifier and input transformer of more sought-after vintage 1176s, and joins the timing controls for both channels to one set of attack and release knobs. Though it does feature a switch to operate in dual mono, the lack of separate attack and release controls for each channel only makes it practical as a stereo unit. - 72

Altec 436C Compressor Amplifier
The Altec 436C is a single channel tube compressor with fixed attack control and variable-mu topology, where ratio increases with the amount of gain reduction. These units are widely used on bass guitars, vocals, and other legato sources.
Though originally shipped with terminal block I/O, many of these units have since been modified with either XLR or TRS I/O, or at least are supplied with pigtails that terminate to either.
EMI in England was famous for modifying these units after purchasing several for Abbey Road when they were unable to attain the Fairchild limiters of the day. They added six switchable recovery times, a "Hold" control, and an output attenuator. - 97
Urei LA-4 Compressor Limiter Pair
The Urei LA-4 is a single channel compressor / limiter in half-rack format with very simple controls for input/threshold and output gain. Ratio control and meter function are selectable on these same two knobs. Attack and release times are not controllable.
The LA-4 used op-amp electronics and saw a couple very minor circuit revisions through its production and cosmetic changes. Black Panel and Silverface versions are largely interchangeable when properly serviced. The LA-4 is a very popular platform for modifications to expand its bandwidth and speed up the slew-rate of the audio electronics.
The rear panel features a high/low sensitivity switch and terminals for input and output connections. Later versions (post 1980) featured rear connections for stereo coupling. - 99
Rupert Neve Designs Portico 5017 Desktop Preamp / Compressor
The Rupert Neve Designs Portico 5017 is a desktop format +66dB mic preamp with "Silk" function/ +30dB direct box / single-knob compressor.
