[Ensemble (Firewire)](https://knowledge.apogeedigital.com/legacy-products?hsLang=en#ensemble-firewire) # Ensemble (Firewire): Maestro 2 Device Settings ![Screen Shot 2023-05-03 at 4.12.23 PM](https://knowledge.apogeedigital.com/hs-fs/hubfs/Screen%20Shot%202023-05-03%20at%204.12.23%20PM.png?width=688&height=222&name=Screen%20Shot%202023-05-03%20at%204.12.23%20PM.png)  1. **Peripheral Prefix** - Use this drop-down menu to assign a letter prefix (A-Z) to each peripheral device dis- played in the Devices Sidebar. The letter prefix is included in all graphic representations of the peripheral as well as I/O labels in Maestro and Core Audio compatible applications. 2. **UV22HR** – UV22HR is applied to the stereo audio path selected in this drop down list. UV22HR should be ap- plied to analog and digital inputs when recording to a 16–bit session and applied to digital outputs when rout- ing signals from Ensemble to 16–bit digital devices such as external CD burners or DAT recorders. UV22HR is only available at sample rates of 44.1k – 48k, as higher sample rate formats and devices support 24 bit operation only. 3. **Optical In** – This drop down list sets the digital format of the rear panel Optical In to either S/PDIF or ADAT/ SMUX. 4. **Optical Out** – This drop down list sets the digital format of the rear panel Optical Out to either S/PDIF or ADAT/SMUX. 5. **Word Clock Out** – The rate of the word clock output may be set in this drop down list to be equal to the unit sample rate (WC x 1) or 1/2 the unit sample rate (WC x 1/2), to accommodate connected devices. 6. **SRC Select** – Sample rate conversion is applied to the stereo audio path selected in this drop down list. When converting a digital input (at any sample rate) to the sample rate of Ensemble (and thus the DAW session), ap- ply sample rate conversion to the digital input. 7. **SRC Rate** – When converting the output of the DAW session to another sample rate, apply sample rate con- version to a digital output (under SRC Select) and select the desired destination sample rate in the SRC Rate drop-down list. 8. **I/O Allocation** – With this drop down menu it’s possible to allocate the number of channels made available through Firewire I/O. When using slower host computers and/or higher sample rates, allocating fewer channels to Firewire I/O means less CPU resources are used for Firewire communication. Please note that when an 18 x 18 allocation is selected, the highest sample rate possible is 96kHz. Also, any hardware I/O may be routed through the available Firewire I/O in the Maestro Routing pages. 9. **CD Mode** – Selecting “On” in this menu sends a 44k1, 16–bit stereo signal to the S/PDIF Coax output, regard- less of the DAW session sample rate or bit depth. CD Mode sets UV22HR to S/DPIF Out, and if the DAW ses- sion is at any other sample rate than 44k1 sets SRC Select to S/PDIF Out and SRC Rate to 44k1. 10. **Over Hold** – By selecting “On”, the red Over indicators on the front panel meters and in Maestro’s Input/Output page remain lit until manually cleared by clicking the Clear Meters button in the Maestro Toolbar. 11. **Meters Display** – The signal displayed by the front panel meters may be set from this drop-down list. Settings available are Off (meters display no signal), Input (meters display Ensemble inputs) or Output (meters display Ensemble outputs). - [BOOM](https://knowledge.apogeedigital.com/boom?hsLang=en#main-content) -
