First off, there's nothing that I'm aware of that's wrong with this unit. I was using it up until 6 months ago for summing with no issues at all, but haven't had it patched in to the network since then, as I’m not doing much mixing. That being said, I'm blowing it out for a quick sale (have other expenses) and selling AS IS just in case. There's some reports from some Sigma users of a high pitched whine in some Sigma's, but I have not experienced that with this unit at all. Just note that as this also requires ethernet network setup that can be a little bit of a pain, but SSL support is usually very good with assisting. The serial # on this unit is S10270.

Description:

For sale is a SSL Sigma Delta digitally controlled analogue summing mixer. Control from within your daw, or via the panel (pictured). Will transfer the iLok license for the plugin. No cables included except power supply (DB25 cables not included).

ANALOGUE HEART

The Sigma offers 16 input channels selectable between mono and stereo as well as direct outs feeding two independent mix buses (Mix A and Mix B) that can also be fed into one another for mix bus parallel processing. There are mix bus inserts, external source inputs and a well-endowed monitoring, headphone and talkback control centre. On the front panel are two customisable user buttons beneath a rotary encoder that selects between the various mix, monitor and headphone output levels. There’s also a mini jack plug for iPhone and laptop input and a 1/4-inch headphone socket. A ‘MIDI learn’ function allows further customising of operations via external MIDI devices and there’s a footswitch socket around the back that can be assigned to various functions but is nominally set up for talkback on/off switching.

It’s clear that SSL wants the Sigma to take over as the hub of your mixing workflow and be its beating analogue heart. In order to do this, a swarm of compact D-sub connectors on the rear panel covers the 32 channels of inputs, direct outs, mix bus inserts, talkback and even some miscellaneous sends and returns thrown in. In order to properly unleash the power of the Sigma and interface it with even a modicum of outboard gear, a comprehensive patch bay set up will definitely be required.

Two sets of monitor outputs and the Mix A output are on dedicated stereo XLR outputs, and there’s an ethernet port and a USB port for factory diagnostics. The only thing letting down the general vibe of supreme compact 21st Century English Analogue Cool is the +12V DC wall wart power supply — unfortunate but true! SSL is quick to point out that the Sigma is built using the same SuperAnalogue circuitry that graces their Duality and AWS consoles and the popular small-format X-Desk. With a price tag well above $5k we’re talking a pretty big outlay here, so the Sigma needs to be judged with the spotlight on an eye for functionality and ease of use as well as a careful ear for sonic performance.
