This article will work through the process of using Peering to incorporate a Hapi mk 2 with an MT 48.
Peering expands IO and incorporates another Merging interface's IO onto the MT 48. The MT 48 can additionally output through the Hapi as well.
To start: both the MT 48 and the Merging interface must be at matching sampling rates.
One should be Master (typically the MT 48), and one slave. This is indicated with a green M and S on the interface's screen.
Next, regarding connectivity: the MT 48 is connected to the computer over USB C, and the Merging Hapi is connected over Cat 5e ethernet to the MT 48 directly.
Only Cat5e or Cat6 ethernet cables should be used to Peer.
On the MT 48, go to Menu > Peering.
Selecting the Hapi will display different options which can be Peered over and controlled on the MT 48.
For example - for additional monitoring, we can peer the Headphone outputs and DA outputs; these can be mapped from Menu > Bus Routing on the MT 48.
Mix 2 now controls the Hapi's Headphone output.
Below, Hapi's AD inputs are being peered to the MT 48. Mixes can now be estabilished on screen - useful when tracking a drumset.
Peered inputs can be recorded; in Menu > Settings > USB IO, the Peered option should be enabled.
These can be pre- and post- FX options (onboard EQ and Dynamics.)
Peering with the MT 48 in Monitoring Mission
When using the MT 48 in Monitoring Mission, the MT 48 becomes a Monitoring Controller.
This can be highly effective for multichannel monitoring applications.
To enable Monitoring mission, hold the Home diamond key and select Monitor on the Mission select screen.
Peering can be enabled here, as can the Settings option.
Go to Peering and enable Inputs and Outputs.
A typical use case might be set to surround sound monitoring, with which monitors are connected to Hapi outputs:
From here, go to Settings > Sources.
Create a New Source, for your Surround Bus in your DAW.
Make sure to give it a name, set the Type appropriately, and map the channels to appropriate USB Outputs.
Then, go to Settings > Monitors. Create a new Monitor set, or edit an existing one.
Name, Mode, Button, and Type must all be set according to the appropriate monitoring type being implemented.
Scrolling further down, Patches defines the output routing.
Scrolling down within here will display any Peered options available. For this example, monitors are connected to the DA 1 card of the Hapi. Selecting Auto will automatically route all channels, in Dolby order.
All monitors can now be controlled from the MT 48.
Outputting from the defined source (a surround sound bus in DAW) will now output through the Hapi's DA card into connected monitors.
If you ever need to verify your routing, open MT Discovery.
Right click on the MT 48, and select Open Advanced Page. Select the I/O Router tab.
This will display all incoming and outgoing routes from the MT 48, including Peering.
This page will look and route differently depending on which mission you select, Music vs Monitor Mission.
