# UAD Satellite Thunderbolt with KVM Switching
## Product Overview
**[UAD Satellite Thunderbolt (Octo)](https://www.sweetwater.com/store/detail/SatelliteTBO--universal-audio-uad-2-satellite-thunderbolt-octo-custom-dsp-accelerator)**
- **Original connection:** Thunderbolt 2
- **DSP cores:** 8 SHARC processors (Octo) or 4 SHARC processors (Quad)
- **Purpose:** Offload UAD plugin processing from host computer
- **Current use:** Studio B (Thunderbolt 2 version)
**Thunderbolt 2 → Thunderbolt 3/4 adapter required:**
- [Apple Thunderbolt 3 to Thunderbolt 2 Adapter](https://www.bhphotovideo.com/c/product/1293724-REG/apple_mmel2am_a_thunderbolt_3_usb_c_to.html) (~$50)
- Bidirectional (works for connecting TB2 devices to TB3/4 computers)
## Mac vs Windows Compatibility
### macOS Support (Excellent)
**All modern Macs work:**
- ✅ M1/M2/M3 Apple Silicon Macs (via Rosetta 2 for UAD software)
- ✅ Intel Macs (2016+) with Thunderbolt 3/4
- ✅ Stable UAD driver support (macOS 12 Monterey through 14 Sonoma+)
**Connection:**
```
Mac Thunderbolt 3/4 port → Apple TB3→TB2 adapter → UAD Satellite TB2
```
**Driver installation:**
- Download UAD Software from Universal Audio website
- Installer handles drivers automatically
- UAD plugins appear in DAW after authorization
**Apple Silicon notes:**
- UAD Console runs under Rosetta 2 (Intel emulation)
- Minimal performance impact
- All plugins work identically to Intel Macs
### Windows Support (Limited but Functional)
**Windows Thunderbolt compatibility:**
- ⚠️ **Thunderbolt support varies wildly** between Windows PCs
- ✅ **Works on:** Dell XPS, HP ZBook, Lenovo ThinkPad P-series with Intel Thunderbolt controllers
- ❌ **Problematic on:** Custom-built PCs with add-in Thunderbolt cards, older laptops (pre-2018)
**Key requirement: Intel Thunderbolt controller**
- Windows PCs need **Intel-certified Thunderbolt 3/4 controller** (not generic USB-C)
- Check manufacturer specs: "Thunderbolt 3 certified" or "Intel Thunderbolt controller"
- Generic USB-C does NOT support Thunderbolt devices
**Driver installation (Windows):**
1. Install Intel Thunderbolt drivers from PC manufacturer (Dell, HP, etc.)
2. Install UAD Software from Universal Audio
3. Reboot after both installations
4. Authorize UAD plugins
**Common Windows issues:**
- **Thunderbolt not recognized:** Update Intel Thunderbolt drivers from PC manufacturer
- **UAD Satellite disconnects randomly:** Disable USB power management in Device Manager
- **Plugins don't appear in DAW:** Run UAD software as Administrator during first launch
**Bottom line for Studio B/C/D:**
- If students bring **Macs** → UAD Satellite will work reliably
- If students bring **Windows laptops** → 50/50 chance (depends on laptop's Thunderbolt implementation)
- **Plan for Windows students:** Have backup workflow (use host CPU for plugins, or limit to Mac-only sessions)
## KVM Switching Scenario: Studio B
### Current Studio B Setup (Hypothetical)
**Your Mac:**
- UAD Satellite connected via Thunderbolt (for your sessions)
- Audio interface (e.g., Apollo Solo) connected via Thunderbolt
**Student brings their laptop:**
- Connects to KVM switch for monitors + keyboard/mouse
- Wants to use UAD Satellite for plugin processing
### Proposed KVM Hub: CalDigit Thunderbolt 4 Element Hub
**[CalDigit Thunderbolt 4 Element Hub](https://www.bhphotovideo.com/c/product/1676742-REG/caldigit_500934_thunderbolt_4_element_hub.html)** (~$180)
**What it does:**
- **4 Thunderbolt 4 downstream ports** (connect up to 4 TB devices)
- **3 USB-A ports** (for keyboard, mouse, etc.)
- **1 Thunderbolt 4 upstream port** (connects to computer)
- **Daisy-chainable** (up to 5 devices in Thunderbolt chain)
- **Power delivery:** 60W to connected laptop
**Key limitation: THIS IS NOT A KVM SWITCH**
- CalDigit Element Hub is a **Thunderbolt hub**, not a KVM
- It **expands** one computer's Thunderbolt ports (4 downstream from 1 upstream)
- It does **NOT switch** Thunderbolt devices between two computers
### The Harsh Reality: Thunderbolt Cannot Be KVM-Switched
**Why you can't switch UAD Satellite between computers like video/keyboard/mouse:**
**Thunderbolt carries PCIe data:**
- UAD Satellite uses Thunderbolt for PCIe DSP communication (not just data transfer)
- When you switch Thunderbolt, devices disconnect and reconnect (like unplugging/replugging)
- UAD plugins unload from DAW, authorization resets, processing stops
**No consumer Thunderbolt KVM exists:**
- True Thunderbolt KVMs cost $5,000+ (enterprise IT management)
- Even those cause device reinitialization (5-10 second disconnect/reconnect)
- Not suitable for real-time audio work
**What happens if you manually switch UAD Satellite:**
1. Unplug Thunderbolt cable from Mac → UAD Satellite disconnects
2. Plug into Student laptop → UAD Satellite reconnects (10 seconds initialization)
3. Student's DAW sees UAD plugins
4. After session: Unplug from Student → Student's session loses plugins
5. Plug back into Mac → Your DAW sees UAD Satellite again (10 seconds initialization)
**Problems with manual switching:**
- 10-second wait every switch
- Your Mac loses UAD access during student session
- Student's session can't be reopened without UAD Satellite connected
- Risk of cable damage from constant plugging/unplugging
## Realistic Studio B Workflow Options
### Option 1: Dedicated UAD Satellite per Computer (Best Solution)
**Setup:**
```
Your Mac → [Your UAD Satellite TB2 + TB3→TB2 adapter] → Your Thunderbolt port
Student Laptop → [Spare UAD Satellite TB3 + CalDigit Hub] → Student's Thunderbolt port
```
**Cost:** ~$1,300 for [UAD Satellite Thunderbolt 3 Octo](https://www.sweetwater.com/store/detail/SatelliteOCt3--universal-audio-uad-2-satellite-thunderbolt-3-octo-custom-dsp-accelerator)
**How it works:**
- Your UAD Satellite stays connected to your Mac (never switches)
- Student plugs their laptop into CalDigit Hub → Spare UAD Satellite available
- Both computers can access UAD plugins simultaneously
- No switching delays, no cable swapping
**UAD plugin licensing:**
- UAD plugins are **iLok-based** (not tied to hardware)
- **You can authorize plugins on multiple Satellites** with one iLok account
- Student needs their own UAD plugin licenses (or use your iLok account during session)
- **Important:** UAD Console software requires online authorization check (student needs internet connection)
**Pros:**
- ✅ No switching complexity
- ✅ Both computers always have access
- ✅ Student can work independently
**Cons:**
- ❌ Expensive ($1,300 for spare Satellite)
- ❌ Student needs their own UAD plugin licenses (or borrow yours via iLok)
### Option 2: Manual Cable Swapping (Free, but Tedious)
**Setup:**
- Keep UAD Satellite unplugged until student session
- When student arrives: Unplug Thunderbolt from your Mac, plug into student laptop
- Wait 10 seconds for UAD Satellite to initialize
- Open UAD Console on student's laptop, authorize plugins (requires internet + iLok)
- After session: Unplug from student, plug back into your Mac
**Pros:**
- ✅ Free (no additional hardware)
- ✅ Works with any student laptop (Mac or Windows with Thunderbolt)
**Cons:**
- ❌ 10-second wait every switch
- ❌ Your Mac loses UAD access during student session
- ❌ Student's session requires UAD Satellite to reopen later
- ❌ Constant cable plugging/unplugging (wear on connectors)
### Option 3: CalDigit Hub for Thunderbolt Daisy Chain (Your Mac Only)
**Setup:**
```
Your Mac Thunderbolt port → [CalDigit Element Hub]
├→ UAD Satellite TB2 (via TB3→TB2 adapter)
├→ Audio interface (e.g., Apollo Solo)
├→ Storage drives
└→ (spare Thunderbolt port for other devices)
```
**What this does:**
- Expands your Mac's single Thunderbolt port into 4 Thunderbolt ports
- All devices (UAD Satellite, Apollo Solo, storage) connect through hub
- **Does NOT switch devices to student laptop**
**For student:**
- Student connects to separate KVM switch (video + keyboard/mouse only)
- Student brings their own audio interface OR uses a spare interface
- Student does NOT have access to UAD Satellite (it stays on your Mac)
**Pros:**
- ✅ Simplifies your Mac's Thunderbolt connections
- ✅ No switching complexity
- ✅ Cheap ($180)
**Cons:**
- ❌ Student can't use UAD plugins (no UAD Satellite access)
- ❌ Requires student to bring their own interface or use a spare
### Option 4: Native Plugins Only (No UAD Satellite for Students)
**Setup:**
- Your Mac keeps UAD Satellite (never shared)
- Student uses native CPU plugins (FabFilter, Waves, etc.)
- Student brings their own audio interface
**Pros:**
- ✅ No Thunderbolt switching complexity
- ✅ Works with any student laptop (Mac/Windows/Linux)
- ✅ No UAD licensing issues
**Cons:**
- ❌ Student doesn't get UAD plugin experience
- ❌ Requires student to use different plugins than you
## Studio C/D Scenario: Apollo Solo with KVM
**[Universal Audio Apollo Solo](https://www.sweetwater.com/store/detail/ApolloSoloTB--universal-audio-apollo-solo-thunderbolt-3-audio-interface)** (~$600)
- **Connection:** Thunderbolt 3
- **Built-in DSP:** SHARC processor for UAD plugins (fewer cores than Satellite)
- **Audio interface + DSP accelerator** in one unit
### Same Thunderbolt Switching Problem
**Apollo Solo cannot be KVM-switched between computers** for the same reasons as UAD Satellite:
- Thunderbolt carries PCIe audio + DSP data
- Switching = disconnect/reconnect (10 seconds, loses audio engine)
- No consumer Thunderbolt KVM exists
### Realistic Studio C/D Workflow
**Option 1: Dedicated Apollo Solo per computer**
```
Your Mac → [Your Apollo Solo] → Your Thunderbolt port
Student Laptop → [Spare Apollo Solo] → Student's Thunderbolt port
```
**Cost:** ~$600 per spare Apollo Solo
**Option 2: Student uses separate audio interface**
```
Your Mac → [Your Apollo Solo] (stays connected)
Student Laptop → [CalDigit TS4 dock] → [Student's Scarlett/Focusrite via USB]
```
**Student uses:**
- Their own audio interface (USB, no Thunderbolt needed)
- Native CPU plugins (no UAD DSP)
- KVM switch for video + keyboard/mouse only
## CalDigit Element Hub: What It Actually Does
**NOT a KVM switch:**
- Does NOT switch Thunderbolt devices between two computers
- Does NOT have multiple "upstream" inputs (one for each computer)
**What it IS:**
- **Thunderbolt port multiplier** for one computer
- Expands 1 Thunderbolt port → 4 Thunderbolt ports
- Useful for connecting multiple Thunderbolt devices to single laptop
**Example use case (CORRECT usage):**
```
Student Laptop (1 Thunderbolt port) → [CalDigit Element Hub]
├→ External SSD
├→ Thunderbolt display
├→ Audio interface (if it were shareable, which it isn't for audio work)
└→ (spare port)
```
**Example use case (YOUR situation):**
```
Your Mac (2 Thunderbolt ports) → Port 1: [CalDigit Element Hub]
├→ UAD Satellite TB2 (via adapter)
├→ Storage drives
└→ (spare ports)
→ Port 2: [Apollo Solo directly connected]
```
This keeps your Thunderbolt devices organized but **does not enable switching to student laptops**.

## Studios B/C/D: Single Display Changes Everything
### Critical Insight: You Don't Need a KVM Switch
**Your observation is correct!** Studios B, C, and D have **single display setups**, which completely changes the hardware requirements.
**With single display:**
- ❌ Don't need TESmart KVM ($470 saved per studio)
- ✅ Just need **Thunderbolt port multiplier** (CalDigit Element Hub, $180)
- ✅ One cable swap = all peripherals rerouted
**Current USB Hub Grey approach:**
```
Student Laptop USB-C → [USB Hub Grey]
├→ Ethernet (internet)
├→ Keyboard/Mouse
├→ Lynx Aurora (Studio B) or PreSonus (Studios C/D)
├→ iLok
├→ Softube Console
└→ HDMI to single monitor
```
**Proposed CalDigit Element Hub approach (SAME workflow, better hardware):**
```
Student Laptop Thunderbolt → [CalDigit Element Hub]
├→ Ethernet (via USB-A adapter)
├→ Keyboard/Mouse (USB-A ports)
├→ Audio interface (Thunderbolt)
├→ iLok (USB-A)
├→ Softube Console (USB)
└→ HDMI to single monitor (via adapter)
```
**What you're missing: NOTHING!**
Your approach is **correct** for single-display studios:
- ✅ One cable swap switches everything (monitor, keyboard, mouse, audio interface)
- ✅ CalDigit Element Hub is exactly the right tool (port multiplier)
- ✅ No need for expensive KVM switch ($470 saved per studio)
- ✅ Thunderbolt devices still face disconnect/reconnect (10 seconds), but acceptable for single cable convenience
### Per-Studio Hardware (Revised for Single Display)
**Studio B:**
- **CalDigit Element Hub** ($180) instead of USB Hub Grey
- Connects: Lynx Aurora (Thunderbolt), keyboard/mouse (USB-A), iLok, Softube Console, HDMI adapter
- Student swap: Unplug Thunderbolt cable from your Mac → Plug into student laptop
- 10-second wait for Lynx Aurora to reinitialize (acceptable trade-off)
**Studios C/D:**
- **CalDigit Element Hub** ($180 each) instead of USB Second Best Hub
- Connects: Apollo Solo (Thunderbolt), keyboard/mouse (USB-A), iLok, Softube Console, HDMI adapter
- Student swap: Unplug Thunderbolt cable from your Mac → Plug into student laptop
- 10-second wait for Apollo Solo to reinitialize (acceptable trade-off)
### Cost Comparison: Single Display vs Multi-Display
**Studio A (3 displays):**
- Needs TESmart KVM ($470) for independent monitor routing
- Needs CalDigit Element Hub ($180) for Thunderbolt organization
- Cannot swap Thunderbolt audio easily (keep separate per computer)
- **Total: ~$650+ for proper KVM setup**
**Studios B/C/D (1 display):**
- Only need CalDigit Element Hub ($180) for port multiplier
- One cable swap = everything switches
- 10-second reinitialize acceptable for single cable convenience
- **Total: $180 per studio**
**Savings for Studios B/C/D:** $470 per studio × 3 = **$1,410 saved**
### What About UAD Satellite in Studio B?
**Your UAD Satellite TB2 can connect through CalDigit Element Hub:**
```
Student Laptop Thunderbolt → [CalDigit Element Hub]
├→ UAD Satellite TB2 (via TB3→TB2 adapter)
├→ Lynx Aurora
├→ Keyboard/Mouse
└→ HDMI to monitor
```
**Trade-offs:**
- ✅ Student gets UAD plugin access
- ✅ One cable swap for everything
- ❌ 10-second wait for UAD + Lynx to reinitialize
- ❌ Your Mac loses UAD access during student session
- ❌ Student needs UAD plugin licenses (iLok sharing)
**Alternative (if you want to keep UAD for yourself):**
```
Your Mac → [Your UAD Satellite TB2 stays connected directly]
Student Laptop → [CalDigit Element Hub without UAD]
├→ Lynx Aurora only
├→ Keyboard/Mouse
└→ HDMI to monitor
```
**This way:**
- ✅ Your Mac always has UAD access
- ✅ Student still gets Lynx Aurora (professional interface)
- ✅ Student uses native CPU plugins (no UAD)
- ❌ Student doesn't get UAD plugin experience
### Shared Single-Display Approach (All Studios B/C/D)
**Per-studio hardware:**
- CalDigit Element Hub: $180
- Apple TB3→TB2 adapter (if needed): $50
- **Total: $180-230 per studio**
**For 3 studios (B, C, D):** ~$540-690 total (vs $2,490 with KVM approach)
## The Bottom Line
### What Works
✅ **KVM switching for video, keyboard, mouse** (TESmart or similar)
- Hardware-based, instant switching
- No device reinitialization
- Works perfectly
✅ **CalDigit Element Hub for Thunderbolt port expansion** (your Mac)
- Organize multiple Thunderbolt devices on your Mac
- UAD Satellite + Apollo Solo + Storage all connect through hub
- Stays connected to your Mac permanently
✅ **Separate audio interfaces per computer**
- Your Mac: Apollo Solo + UAD Satellite (via CalDigit Hub)
- Student: Spare Apollo Solo OR spare USB interface
- No switching complexity, both computers always have audio access
### What Doesn't Work
❌ **Switching Thunderbolt devices (UAD Satellite, Apollo Solo) between computers**
- Thunderbolt is PCIe data, not just video
- No consumer KVM exists
- Causes device disconnect/reconnect (5-10 seconds)
- Loses audio engine, plugin state, authorization
❌ **Using CalDigit Element Hub as a KVM**
- It's a Thunderbolt port multiplier for ONE computer
- Does NOT switch devices between two computers
- Has only 1 "upstream" port (not 2+ for multiple computers)
### Best Recommendation
**Studio B/C/D setup:**
1. **KVM switch for displays/keyboard/mouse** (TESmart HKS403-P23, $470 per studio)
2. **CalDigit Element Hub for your Mac** (organize Thunderbolt devices, $180 per studio)
3. **Separate audio interfaces:**
- Your Mac: Keep your Apollo Solo + UAD Satellite (connected via Element Hub)
- Student: **Spare USB audio interface** (Focusrite Scarlett 2i2, $180)
- **Skip the spare UAD Satellite/Apollo** (too expensive, $600-1,300 per studio)
**Why spare USB interface instead of spare Apollo/Satellite:**
- Much cheaper ($180 vs $600-1,300)
- Student still learns professional recording workflow
- No UAD licensing issues
- Works with any student laptop (Mac/Windows/Linux)
- You keep UAD plugins for your sessions (not shared)
**Total cost per studio:**
- TESmart KVM: $470
- CalDigit Element Hub: $180
- Spare Focusrite Scarlett 2i2: $180
- **Total: ~$830 per studio**
**For 3 studios (B, C, D):** ~$2,490 total
This avoids the Thunderbolt switching problem entirely while keeping costs reasonable.
## Windows Laptop Compatibility Summary
**If student brings Windows laptop:**
- ✅ **Video/keyboard/mouse via KVM:** Works perfectly (any Windows laptop)
- ✅ **USB audio interface:** Works perfectly (class-compliant or Windows drivers)
- ⚠️ **UAD Satellite via Thunderbolt:** 50/50 chance (depends on laptop's Thunderbolt controller)
- ✅ Works: Dell XPS, HP ZBook, Lenovo ThinkPad P-series (Intel Thunderbolt)
- ❌ Problematic: Custom PCs, older laptops (pre-2018), non-Intel Thunderbolt controllers
**Bottom line:** Use spare USB audio interface (not spare UAD Satellite) to avoid Windows Thunderbolt compatibility issues.
