TTSH: The 2600 Project

Low-Gain Electronics is offering a build commission service for the Two Thousand Six Hundred project by Zthee (thehumancomparator.net), to those not wanting to DIY. It has a portable suitcase style case with handle and lid. Tolexed in black it will be built to look like the classic 2600 but protect your 2600 much better than the original.

Price for the commission will be $3500 USD**
This includes shipping (usually around $200USD) within the 48 states*

Payment is made in 2 parts:
50% deposit ($1750)to get the project started
50% ($1750) upon completion when the unit is ready to ship


* international shipping will require a small fee caculate & invoiced when ready to ship.
**3% PayPal/Convenience fee applied to commissions placed with PayPal/Credit Cards

Build time will take anywhere from 4-7 weeks from the time you order. Depending on the volume of orders, parts availabilty, and when you place your order, it could take up to but not limited to 10-12 weeks. When things pick up we will try to keep one or two units in stock so the wait times keep to a minimum. We will keep you updated as to the status of your build. It will definitely be worth the wait! Orders are shipped on first come first serve basis. Commission price get's you the TTSH. This includes... EVERYTHING pcb/panel kit, parts, case and covers labor for building the synth. So when you place an order with us for the commission build you will receive a built/tested/ready to play TTSH synthesizer. Simply open the box, plug in the synth and start enjoying that classic 2600 sound!

Wait times will be longer at first due to part/kit ordering, but as things progress it will speed up.

If you aren't willing to wait, don't commission the job.



Please contact: logan at lowgain-audio dot com
to place your order to get your spot on the list to ship.
Include the following information:

1. Your full name
2. General location
3. Which case option you would like***
4. What payment method you plan on using (Paypal/Credit Card/Money Order)


*** At thie time I am only offering TTSH Commissions in the Black Suitcase model.

You will receive a response notifying you that we have received your email and will send an invoice for the commission. Commissions are not started until deposit payment is made. There is a 25% (of total commission price) restocking fee for refunds since specialty parts are ordered when you make the deposit on your commission. This means if you break the commission contract and want a refund you will lose $875 of your initial deposit.

**This is a commission build. The TTSH is not an original product/project of Low-Gain Electronics. Simply offering to build it for those not interested in DIY building the PCB/panel kits soon to be available here. This project is an advance build so it's not recommended for the novice DIY builder**

 

 

Control Voltage Processor (CVP-1):
Dual 1 to 3 active buffered outputs with true Bipolar attenuverters. 
What that means is when the knob is set to the middle (detented for ease of use) there is 0 voltage/signal being passed to the output. I've found a lot of bipolar attenuverting circuits that rely on phase cancellation to have bleed when set to what should be 0 due to not having enough of a null range in the middle. The CVP-1 does not have that problem!

When the input is not being used it has an internal 5V source normalled to it. Which means you can send up to +/-5V to 3 different places at once! It also provides offset voltages for the Mix Section (see blow)

The CVP-1 contains two of these "aux send" circuits and in the middle lies a MIX section. The inputs to the mix section are taken from Channel 3 outputs on each side of the CVP-1. There is a SUM output and an OR output. These are kind of a summation of the SubMix concept and the Short Bus concept wrapped into one module. It will allow for a large range of functions!

The CVP-1 is DC coupled and works very well for Audio signals much like an "aux send" module to send signals to various places through out your system.

SubMix6 (SM6):
Back by popular demand , the SubMix 6 is an improved concept over the original SubMix7. Featuring 6 active/buffered inputs, with linear attenuators, with two dedicated mix outputs labeled A and B, and one dedicated SubMix output labeled AB.

Mix Option: (Available Simultaneously)

(2) 3 inputs x 1 output x (1) submix output
(1) 6 inputs x 1 output
That's half the functionality of the original SubMix in less than a quarter of the size!

The SubMix 6 was designed with the intention of sub-mixing the waveform outputs from VCO's. Passive Mixers tend to function more like waveform "on/off" switches with little in between for mixing options. With active inputs, the load on the summing bus stays constant and you get a smoother, more gradual mix, regardless of the load on the input.

The SubMix6 is CV and audio friendly, keeping in mind you will have offset/clipping if you use the submix output of the mixers that are mixing AC (Audio) and DC (Control) signals at the same time.

You can also take advantage of the submix output and experiment with feedback loops!

Features

Twin 3 input mixers with dedicated outputs
Submix output sums both mixers, allowing 6 input mixing
All outputs are available simultaneously
Active/buffered inputs
Linear attenuators
Feedback loop functionality
Skiff friendly

SubMix:
The SubMix is an improved concept over the original SubMix7. I wanted more room to play around with the mixer in live situations. It now has 12 active inputs, with linear attenuators, allowing the user to have up to 7 different mix outputs. There are four dedicated mix outputs labeled A, B, C, D. There are also 3 dedicated submix outputs labeled AB, CD, and ABCD.

Mix Options: (Available Simultaneously)
(4) 3 in x 1 out
(2) 6 in x 1 out
(1) 12 in x 1 out

The SubMix was re-designed with the intention of sub-mixing the waveform outputs from VCO's. I've found by using passive mixers I'd hear drop outs or "nulling" of signal which sounds similar to phase cancellation. So passive mixers functioned more like waveform "on/off" switches for me. This effect was due to the different loads being created on passive input nodes (typically caused by the attenuator varying the load). With active inputs (unity gain buffers) the load on the summing bus stays constant and you get smoother/more gradual mix regardless of the load on the input.

The SubMix is CV and Audio friendly, keeping in mind you will have offset/clipping if you use submix outputs of mixers that are mixing AC AND DC signals.

You can also take advantage of the submix outputs and play around with feedback loops!

Short Bus V2:
The Short Bus is a seven input OR combiner. Aside from its new facelift (.060" powder coated steel panel) it has newly upgraded toggle switches which allow you to easily select one of three options, two dedicated bus outputs (labeled A and B) or you can select the "Off" position. The Short Bus allows for easy mixing of gate, trigger, and clock signals. You can "mix" CV with the Short Bus, however all negative voltages will be ignored. High voltage at the inputs takes priority and voltages are not "Summed". The OR combiner diodes have been upgraded to allow for lower voltage drops. Forward voltage drop average is now around .18V instead of .7V.

6HP, 0mA (Passive)
Retail: $99USD

UTL-1:
The UTL-1 is a passive* bi-directional Banana Jack <=> 1/8" (3.5mm) format jumbler. With the ability to work with every format of modular that uses banana or 3.5mm jacks. The UTL-1 comes in handy when interfacing different modular systems together. Just connect the ground jack (black jack located on the side of of the UTL-1) to your banana modular systems power supply ground jack and you're ready to go!

*this unit is passive and does not perform
any voltage/level scaling/offsets


Built from the same die cast aluminum enclosures used for boutique effects pedals, the UTL-1 is built like a tank and can take a beating.

Retail: $89USD

UTL-2:
The UTL-2 is a passive* bi-directional Banana Jack <=> 1/4" format jumbler. With the ability to work with every format of modular that uses banana or 1/4" jacks. The UTL-2 comes in handy when interfacing different modular systems together. Just connect the ground jack (black jack located on the side of of the UTL-2) to your banana modular systems power supply ground jack and you're ready to go!

SubMix7: (Discontinued)

The SubMix7 is a seven active input mixer. With 6 linear attenuated active inputs and one direct active input the SubMix7 allows for mixing of AC or DC signals. The direct input makes it easy to daisy chain mixers to allow for more inputs if needed.

The SubMix7 was designed with the intention of sub-mixing the waveform outputs from VCO's. I've found by using passive mixers I'd hear drop outs or nulling of signal which sounds similar to phase cancellation. So passive mixers functioned more like waveform "on/off" switches for me. This effect is due to the different loads being created on passive input nodes. With active inputs (unity gain buffers) the load on the summing bus stays constant and you get a smoother/more gradual mix regardless of the load on the input.
