Motu M4 interface

Postby Tony EI7BMB » Sat Jun 06, 2020 12:17 pm

Just got the MOTU M4 interface to replace my UMC 204 unit. Really like it so far . I have the MOTU set at 96000 sample rate and 128 buffer , same for VAC 1. Its a lot easier to monitor my own voice now on Thetis for testing with so much less latency , some may even find it ok for QSO's too.

Tony,

Sounds like those drivers are top notch. This is particularly noteworthy because that interface is really only a USB 2.1 interface regardless of the connector type.

Roger that Scott , drivers making the most of USB 2 I think. Very straightforward installation and with the nice LCD display its easy to see whats going on level wise.

How can you determine that?

[/quote]The spec's on the Motu say "USB-C (compatible with USB Type A) 2.0 audio class compliant". That is marketing-speak for "We put a USB C connector on it but it's really only running USB 2.0."

There are a growing number of sound interfaces with USB C connectors that only run USB 2.0 (or 2.1, whatever). If you look at their spec's, or the many reviews of them on the internet, you will find they are all like this. No doubt they are all using the same chipsets for the interface, too. That's why they all nearly look the same in terms of functionality and features, the building blocks, the chips, are all the same.
