The Solid State Logic E-Series Dynamics Module for API 500 Series Rack is a single-unit API 500 Series lunchbox-style compressor/limiter and expander/gate module. The device utilizes a similar circuit design and components as the original SSL E-Series channel strip, including a true RMS converter in the sidechain and a gain element that replicates the original Class A VCA chip.

Half of the module consists of a compressor/limiter with a ratio control that allows you to select from no compression to full limiting. You can change the curve from over-easy to hard-knee style compression with the push of a button. A threshold knob allows you to set the threshold at which point compression occurs between +4 and -26 dB. A release knob allows you to set the release time between 0.1 and 4 mS. A linear release button allows you to switch between a linear and a logarithmic release curve, and a fast attack button allows you to change the attack time from 3 ms for a 20 dB gain reduction to 30 ms for a 20 dB gain reduction. For metering, the unit has a 5-segment LED meter that shows the Compressor/Limiter activity in red and yellow and the Expander/Gate activity in green.

The Expander/Gate component of the module features an EXP button for switching between a 20:1 gate and a 2:1 expander. You can set the range of gating or expansion between totally inactive to up to 40 dB. A threshold knob sets the level at which the gate or expander engages between +4 dBu and -26 dBu. The threshold circuitry is designed with variable hysteresis which increases in relation to the threshold being lowered. This allows the sound of a musical instrument to decay below the threshold and before being gated or expanded by the module. The Expander/Gate section of the unit generally has a linear attack time of 1.5 ms per 40 dB, but this can be changed to a faster attack time of 100?s per 40 dB with the push of the FAST ATT button. A release knob allows you to adjust the time between 0.1 and 4 seconds at which the Expander/Gate will reduce the signal level after it is under the threshold. There is also a dynamics "In" button that allows you to put the entire module in or take it out of the circuit in your API 500 lunchbox-style rack.

Good Solid Mount
Got for my 2019 TRD Off Road. Works great, solid mount. Phone easy in, easy out once you get used to it. Looks and feels well made.

Solid Product
I was a bit skeptical based on the price ($85 total after taxes) but you can tell that for the price, this thing is sturdy and high quality. Holds solid onto the vent and keeps my iPhone in place. Easy to adjust and move to your liking, also easy to turn 90* and have your phone sideways. Only drawback is that is obstructs the view of the clock on my 4Runner and slightly obstructs my windshield, but I am sure I will get used to it.

Great phone holder
I use this phone mount in my Subaru Impreza, and it works perfectly with my vents. It holds my phone super securely—no wobbling or slipping—so it’s great for navigation or hands-free use. Really solid and reliable for the price.

Excellent product.
First impression: excellent product. The only reason I deducted a star is because the price is obviously quite insane.

A+ mount for 4Runners
This is the best phone mount I've ever had. Got it for my 2021 4Runner. Very strong, doesn't come loose, easy to place and remove the phone from the mount. Can't recommend enough.
