Remote Controlled Analogue Summing

〜伝統の SSL アナログコンソールサウンドと PC ベースの高効率な制作環境とを両立させたいすべての DAW ユーザーのために〜

Sigma δelta は、SSL の SuperAnalogue™ サウンドクオリティーで DAW のオートメーションによりミキシングする新しいコンセプトのサミングエンジンです。MDAC を使用してのアナログレベルコントロールは Duality や AWS といったスタジオコンソールに搭載されている機能と全く同じのものです。お使いの DAW で作成したフェーダーオートメーションデーターを使用して Sigma δelta の MDAC を制御し、100% アナログの環境でトラックをミックスダウンできます。

Sigma δelta は、個別にモノまたはステレオに切り替えられるフレキシブルなチャンネルインプットを 16 系統 (最大 32ch 入力) 持ち、全チャンネル分の正確な LED メーター表示が装備されています。２系統のステレオバスにはそれぞれに専用の出力と個別のステレオインサートポイントを持ち、各チャンネルにはダイレクトアウトも装備されています。また、Mix Bus B はファイナルミックスの際などに Mix Bus A に統合してお使いいただくことも可能です。

モニターセクションには、アーティストモニターのためのヘッドフォンアウトとスタジオモニターのためのモニターアウトが装備されています。モニターアウトはメインとオルタネイトの2系統を装備しており２つのモニターセットを接続できます。モニターソースはマトリックスをフロントパネルのスイッチでセレクトすることで切り替えられます。フロントパネルに実装されているポットにより Mix A、Mix B、モニターアウト、ヘッドフォンアウトを切り替えてそれぞれ独立してレベルコントロールできます。また、トークバックインプット (ラインレベル)、モニター Dim (レベル調整可能) も装備しています。

Sigma δelta は、モニターレベル、モニターソース切り替え、インサート、トークバック、B to A サミング、モノチェックなど機能は MIDI を介して一般的なコントロールパネルから操作できます。MIDI の簡易学習機能を使用して効率的なセットアップが可能です。また、フロントパネルにある２つのユーザースイッチの On/Hold や背面のフットスイッチ入力により同様の機能の切り替えを簡単かつ素早く行えます。 Sigma は、ipMIDI を介して PC と接続し、プラットフォームを問わずさらに広範な機能の追加や設定変更を分かりやすく自在に行うことができます。

Powerful and very flexible

It has 16 stereo input channels which can be individually switched between being mono or stereo for up to 32 channels at mixdown. There is accurate metering for all channels via LED meters on the Sigma hardware unit. There are two stereo mix busses with dedicated outputs and individual stereo insert points to facilitate implementation of parallel compression or convenient printing of stems back to the DAW with processing applied. Mix Bus B can also be injected into Mix Bus A for final mixdown. Providing further flexibility, Mix Bus A & B inserts also include an 'insert sum' feature to sum the insert return to the mix bus.

Each input channel also features individual direct outputs for printing individual channels back to your DAW. The inclusion of direct outputs streamlines integration of analogue processing, with a typical configuration connecting DAW I/O outputs to outboard processor inputs, then processor outputs to Sigma inputs and Sigma direct outputs back to the DAW I/O. Unlike "dumb" analogue summing boxes, with this configuration, the gains of each channel on Sigma are automatable POST the outboard processors eliminating the effects of volume change inside the DAW riding into outboard compressors.

An Artist and Studio monitoring section provides separate Monitor and Headphone circuits. The Main monitor output has Main and Alternative connections to accommodate 2 sets of monitors. A comprehensive switching matrix enables selection of monitor source and output. A large front panel level control uses a push-select mechanism to determine whether it adjusts Mix A, Mix B, Main Monitor or Headphone. There is also a Talkback input with adjustable Dim level. A handy front panel ijack input (3.5mm stereo socket) feeds into the monitoring section.

The Sigma Remote app offers full control of all Sigma functions plus store and recall of saved settings. It runs on a Mac, PC, iOS or Android tablet device and connects to your workstation via Ethernet (or wirelessly from a tablet via a wireless router). The user interface provides a series of intuitive pages that makes controlling Sigma's powerful feature set straightforward. Three main screens provide control and setup of the Master Section, Channel Control and Global Settings parameters. Every parameter can be saved for future recall making swapping between projects simple and efficient.

Sigma δelta supports full direct remote control of the mix engine from any SSL MCU-compatible control surface. Supported channel functions are level, pan, solo, mute, mono/stereo, and mix bus routing. Channel labels as well as volume and pan data are returned to the surface for display. The Dim, Cut, Mono and Alt monitor functions, as well as Talkback, can be controlled from MCU F-Keys. MCU control is via MIDI over Ethernet and shares the same Network link as the Remote app and δelta-Control. Similar functionality is also available with Eucon enabled devices.

The Sigma rack unit houses the analogue summing engine, provides connectivity, a set of bright status and level LED's, hardware controls, headphone socket and ijack input. A pair of user assignable dual action push/hold buttons on the front panel plus a foot-switch input can be assigned to the master section functions. The rear panel provides dedicated XLR connections for the Mix Bus A and the Main and Alt monitor outputs. The individual line inputs and direct outputs are connected via standard 25pin D-Sub. An additional pair of D-Sub connections handle Mix Bus inserts, Mix B output and line level Talkback input.

δelta-Control (δ-Ctrl)

The unique new SSL console automation system unites the very best of automation in the analogue console domain with DAW based workflow

The δelta-Control (δ-Ctrl) Single Fader Plug-in is a native AAX/RTAS/VST/VST3 plug-in that allows automation of Sigma channel volume as if it were a DAW plug-in. Inserting 16 instances into the DAW session will allow control of volumes and cuts for all 16 of Sigma’s channels. The automation system in the DAW is used to record and playback Sigma volume control data entered either directly from the fader in the plug-in GUI or from a SSL MCU control surface which is controlling Sigma directly.

The 16-fader ‘Sigma Delta 16’ plug-in provides compatibility to Logic users, as well as offering an alternative workflow to ‘Sigma Delta Single Fader’ plug-in users. The plug-in is available all formats including AAX/AU/VST3/VST.

The Sigma Delta Mix Bus plug-in also allows users to automate Sigma’s two stereo mix busses and their insert points. Plus the Sigma Delta Monitoring plug-in allows full control of Sigma’s monitoring section, including monitor and headphone levels, monitor cut, dim and source selection. It allows Sigma's Monitoring section to be controlled from your DAW, a control surface or the SSL Remote Application running on a computer or a tablet device.
