The ExIst Audio Ecosystem

TS09 (The Selector 09) & MC09 (Master Control 09)

Two precision-crafted devices that bring vintage tape workflows into the modern networked era. Route, measure, and control every deck in your studio from a single unified system.

The Ecosystem: Better Together

MC09 (Top) + TS09 (Bottom) — Front View

When paired, the TS09 handles audio routing and level measurement, while the MC09 handles physical transport control, visual feedback, Precision Tone Generation, and MasterLink™ hub functions. Both devices are connected via a PoE++ network, exchanging lightweight data packets using the MQTT protocol. No audio travels over the network; only control data and VU meter levels.

The Multi-Deck Macro Workflow

Imagine you want to dub from your Technics RS-1500 (Port 02) to two Nakamichi Dragons (Ports 03 & 04) simultaneously:

Route Audio on TS09

CH 02 (Technics RS-1500) → Output A (PLAY)
CH 03 & 04 (Nakamichi Dragons) → Output B (RECORD)

Send Macro Command

TS09 switches relays and sends MQTT command to MC09:

"Port 2: PLAY at T+0ms, Port 3 & 4: REC at T+50ms"

MC09 Executes

Checks safety interlocks, then fires the 135-channel optocoupler matrix with the specified stagger delays.

Synchronized Feedback

All decks engage. MC09 touchscreen shows "SYNC: 2▶ 3● 4●". Analog VU needles bounce to life.

Unified Stop

Press STOP on the MC09 transport button. All decks stop. Both displays update instantly.

Infinite Scalability & Single-Cable Power

The 09 Series is designed to grow with your collection. Daisy-chain multiple MC09 units to control dozens of vintage decks, or link up to 5 TS09 units on a single 60W PoE++ port to expand your routing matrix to 45 independent channels.

PoE++ Power & Data in Series

Forget power bricks and messy cables. The entire ecosystem runs on IEEE 802.3bt (PoE++). Dual Ethernet ports on each unit provide both power and network data. Your MC09 can pass data to a connected TS09, while a standalone PoE++ injector powers each unit cleanly.

MC09 + 2× TS09 — The Ultimate Studio Stack

All Your Analog Sources, Under One Roof

For the home audiophile, this means the ultimate dream: every reel-to-reel, cassette deck, and vintage source in your collection, perfectly routed, safely controlled, and beautifully metered from a single, elegant interface.

Chassis & Finishes

Choose Your Aesthetic

Both the MC09 and TS09 are available in two precision-crafted chassis finishes: our signature raw CNC-machined Aluminum, or the deep, stealthy Noir (Black Anodized). Use the toggle on each image to preview the Noir version. Both chassis options can be upgraded with hardwood veneer side panels or fitted with standard 19" rack handles.
