TC-500 // Versatile Tracking Compressor for 500 Series.
« on: October 07, 2020, 08:57:17 PM »
Hi Guys,

here's my latest project  ;)





Let's start with a bit of history. Some of my friends and colleagues are dialogue and foley recording engineers. They have been asking for a transparent compressor that could adapt easily to the incoming signal and help control wide dynamic range recordings.

The first prototype I made was a VCA compressor with RMS detection. It worked beautifully on vocal, but the foley guys needed something to tame the peak as well... So I added a second stage of VCA compression with peak detection. This is not a limiter, but more a peak attenuator. The ratio is fixed at 2:1, Attack & Release are also fixed. You simply turn the knob to the desired amount of gain reduction.

Here’s a small diagram showing the configuration:

The goal here was to make a versatile compressor that is easy to use and gives great results fast. I’m really happy how it turned out  :D
It’s already in the recording chain of two local studios and it saved numerous dialogue takes from clipping the converters.

I should have a small demo video ready next week (various instruments & vocal tracks)

As usual, if there’s enough interest I could make a small batch of kits available on the white market.

Cheers
Gabriel

Very cool, great work!

If kits were made available, I'd be interested for sure!  Is this VPR compatible, 51x...?  EDIT: Well, the title says 500 series, so I guess I asked a dumb question.  ;D

Looks amazing.....

One thing you could try is to put the Peak Limiter before the compressor. I have found in the past that this "helps" the Compressor stage. It seems to allow the Compressor to work more easily and just compress the signal and not have to deal with extreme transients.

I used to have 2 dbx 165s and the first just did some slight Limiting, trimming the peaks off, and the second 165 was the main Compressor. Sounded absolutely gorgeous. The 165 internally is set up as compressor first and then limiter.

It even works in the digital domain as well. In my Protools template I have all my channels set up in this way, Limiter first then Compressor. I find the Compressor sounds more natural and nicer.
If opportunity doesn't knock, build a door.

Hi Guys,

sorry about the late reply... busy week  ;)

The partial kit cost $145 USD
+ shipping (1-2 modules)
$20 US & CANADA
$40 International

Unfortunately I can't offer cheaper alternative to ship internationally with a tracking number... Canada Post recently raised their prices.

The kit will include:
- Front Panel
- ENIG PCB
- Knobs
- Jensen Transformer
- Alpha Rotary Switch (Ratio)
- Build Guide


The rest of the components will be available thru a single Mouser cart for approximately $105 USD.

I'm supplying the Alpha switch because it comes with a 20mm shaft that needs to be cut. I'll do the work for you.
Also, That Corp is having a hard time supplying parts to their distributor at the moment due to the covid-19.
Mouser will have the 4305 IC back in stock the first week of december. This will make a nice Christmas project  ;)


I will create a thread on the white market this week to start taking orders. I should have around 20 kits available. First come, first served. The kits could ship in 4 weeks.

I'll try to upload a small demo video this week to show how the compressor behave  ;)

Thanks

Just got bad news from Mouser today. They won't have the That's 4305 IC in stock before the first week of December. I wanted to include them in the kits, but I decided to readjust the price and they will be part of the Mouser Cart instead.
Thanks
