#### How do I install modules in a Symphony MKII chassis?
Installing modules in a MkII chassis is shown [here](https://knowledge.apogeedigital.com/symphony-i/o-installing-i/o-modules?hsLang=en). This is identical for MK1 and MkII units.
- 8MicPre cannot be used with **16x16SE.**
- 8MicPre cannot be used with any 2x6 module.
All compatible modules can be installed in either slot 1 or 2 in Symphony Thunderbolt units.
#### **How to update compatible modules to current firmware?**
For Mac OS 10.5.7 and above all compatible Symphony MkII modules can be updated with the current Symphony Control driver that can be downloaded [here](https://apogeedigital.com/installer-downloads)
This will install:
- **Symphony Control Software Version: 0.5.13**
- **Firmware: 0.9.B0.21 FPGA 0.51**
With Symphony MKII connected in Thunderbolt audio interface mode or in Pro Tools HD mode with a USB connection this firmware can be updated with the Symphony Firmware Updater app included in the driver.
**Connectivity & Update Process for Mk1 Modules:**
| **Connection Style** | **User Installable** | **Possible Error Messages** | **How To Update** |
| --- | --- | --- | --- |
| Thunderbolt | Yes | None | Regular Firmware Updater included with [MkII Software Installer](https://apogeedigital.com/installer-downloads#installerform) |
| Pro Tools Plus | No | - | Must be sent to Dealer or Authorized repair center |
| Dante | Yes | Symphony Control Prompts for unnecessary Update would actually downgrade unit | Special Dante Updater (Contact [Support](https://apogeedigital.com/company/contact)) |
**How to check which firmware I need for my Symphony MKII configuration:**
