The majority of the [[Recording Studios]] in the New Adelphi Building (1 thru 6) use the RME M32 AD/DA combination for digital conversion, converting analogue signal into digital information. Unlike what you might be used to when using an audio interface at home, where conversion and transfer is often combined, the RME's simply convert the analogue audio into a selection of different digital formats. The process of then transferring this information into the computer is then handled by a selection of additional interfaces depending on your choice of DAW.

[[Recording Studios]] 1 through 6 use the RME M32 AD/DA combination for digital conversion, encoding analogue signal into digital information and back again. Unlike converters you may be used to when using an audio interface at home, where encoding and transfer are often combined, the RME interfaces blindly convert analogue audio into a selection of different digital formats. The process of transferring this digital signal into the computer is handled separately by a selection of additional interfaces. Which ones you use will depend upon your choice of [https://en.wikipedia.org/wiki/Digital_audio_workstation DAW].

The RME M32s act autonomously so any changes you might need to make, such as changing your sample rate, need to be made on the front panels of the units. Likewise any changes you make on the front of the M32s will not be carried over to your chosen DAW, these settings need to be made to match. For example: if you wanted to recording in Logic X at 44.1khz you would have to make sure that the sample rates matched both in your logic project and on the RMEs.

As standard the RME M32 AD, the top unit, acts as the Master Clock for each studio, keeping both the digital converters in synchronisation with each-other and the computer. This ensures stability when recording and ensures you avoid any nasty pops and clicks when recording where there should not be any. For the majority of the time this will mean the top unit's clock section will simply show the sample rate your are intending to record at.

You can also choose to use the New Adelphi Buildings Master Clock as well by setting the RME M32 AD's Clock Section to "Wordclock", although this is fixed at a sample rate of 48khz so while it can be used for recording at this speed it is most useful if you're recording across the building or running an Audio for Video/Media project.

Instead of generating a master clock signal locally, you can use the New Adelphi [[Master Clock]] by setting the RME M32 AD ''Clock Section'' to '''"WCK"''', meaning ''[https://en.wikipedia.org/wiki/Word_clock Word Clock]''. However, this is fixed at a sample rate of '''48kHz''', so your session must also be configured to run at this rate. There are details as to why the house clock runs at 48kHz on the [[Master Clock]] wiki page.

The recording studios were designed to allow you to use your own laptop instead of the provided iMac should you wish. To do this, you must use the '''RME MADIface''' interface by connecting your laptop to the USB port labelled ''MADIFACE'' on the control room [[Connectivity Panel]]. This provides 64 simultaneous input and output channels between your laptop and the RME M32 converters, giving 128 channels of audio over standard [https://en.wikipedia.org/wiki/USB#USB_2.0 USB 2.0].
  
−
It is possible in all the different studios to use your own laptop as a substitute for the provided iMac, studios 1-6 use RME's Madiface technology to allow for near complete integration with the studio. Your laptop can be connected to the Madiface using a USB cable which in turn transfers digital audio to and from the RME M32 converters using the optical cable option.
+
To use the '''MADIface''' interface you need to install the [http://www.rme-audio.de/en/downloads/driver/uc.php free driver from the RME website]. Look for '' 'MADIface XT / USB / Pro' '' in the downloads and install the correct version for your Mac or Windows system. Linux systems using ALSA v1.1 and above should work with no additional driver.
  
−
Firstly you will need to download and install the RME Madiface drivers and software to your laptop, these can be found on the [http://www.rme-audio.de/en/products/madiface_usb.php| RME website] and then ensure the RME is set to the same settings as in the image above. You will also need to ensure your settings match those on the front RME M32s in the "Fireface" dialogue box that appears upon connecting the Madiface to your computer.

Once you have configured the RME M32s to the correct settings for your chosen DAW, you may wish to work in a sample rate other than 44.1kHz. The RME M32s offer clock speeds of up to 192kHz, though the most common alternative is 48kHz.

If you intend to use a 48kHz sample rate it is best practice to set the M32s to follow the [[Master Clock|house clock]]. Simply set both the AD and DA units to ''Word Clock'' by choosing '''WCK''' from the ''CLOCK SECTION''. When configuring your DAW, choose the ''Word Clock'' or ''External Clock'' option.

 +
For other frequencies, the '''M32 AD''' (top unit) should always be the device generating the local clock pulse. The M32 units only generate 44.1kHz or 48kHz frequencies, but can clock up to 192kHz by multiplying this signal by two or by four. You choose the multiplier using the ''STATE'' option in the ''CLOCK SECTION''. This ''STATE'' must be set on '''both''' M32 units to work.

Recording Studios 1 through 6 use the RME M32 AD/DA combination for digital conversion, encoding analogue signal into digital information and back again. Unlike converters you may be used to when using an audio interface at home, where encoding and transfer are often combined, the RME interfaces blindly convert analogue audio into a selection of different digital formats. The process of transferring this digital signal into the computer is handled separately by a selection of additional interfaces. Which ones you use will depend upon your choice of DAW.

REMEMBER: IF YOU ARE EVER UNSURE ABOUT HOW TO USE THE RME ASK AT THE STUDIO OFFICE FOR HELP!

USING THE WRONG SETTINGS CAN COMPLETELY RUIN A WHOLE SESSIONS' WORK.

The RME M32s act autonomously so any changes you might need to make, such as changing your sample rate, need to be made on the front panels of the units. Changes will not be carried over to your chosen DAW automatically; these settings need to be made to match. For example, if you want to record in Logic at 44.1kHz, you have to make sure that the sample rate matches both in your Logic project and on the RME converters.

Clocking with the RMEs

As standard, the RME M32 AD (top unit) acts as a local master clock for each studio, keeping the digital converters and the computer interface in synchronisation with one another. This ensures stability when recording and ensures you avoid any nasty pops and clicks when recording. For the majority of the time this will mean that the AD unit's Clock Section will simply show the sample rate at which you are intending to record, usually 44.1kHz.

Instead of generating a master clock signal locally, you can use the New Adelphi Master Clock by setting the RME M32 AD Clock Section to "WCK", meaning Word Clock. However, this is fixed at a sample rate of 48kHz, so your session must also be configured to run at this rate. There are details as to why the house clock runs at 48kHz on the Master Clock wiki page.

Using the RMEs with Logic

When using Logic with the RMEs, the digital protocol is ADAT. The RMEs send and receive the digital signal between an RME HDSPe 'RayDAT' PCIe card held within a metal chassis (the mysterious black box with the blue light either above or below the RME M32s). This is connected via an extra long optical Thunderbolt cable to the iMac in the recording studio control room.

How both the RME M32s should look when recording in Logic at 44.1khz

In the image above you can see how the RMEs should look when recording in Logic at 44.1kHz. Unless you wish to experiment with other sample rates, it is most likely that this is how you will be recording into Logic.

The M32 AD (top box) is operating as the master clock in this instance, meaning that the CLOCK SECTION is showing the sample rate being generated and sent to the M32 DA (bottom box). This is the rate at which your Logic session should be configured to run.

The M32 DA (bottom box) handles the conversion of digital audio back into the analogue domain. This requires the most adjustment between different recording setups. Ensure the ADAT input has been selected by pressing the 'sync' button in the ADAT section. Also ensure that the CLOCK SECTION of the DA has ADAT chosen by pressing the 'select' button (on the left) until ADAT is selected.

In Logic, your project sample rate should be set to match the one chosen on the M32 AD and select HDSPe RayDAT as your recording interface.

Using the RMEs with Pro Tools Ultimate

When using Pro Tools Ultimate with the RMEs, the digital protocol is MADI, connected over BNC cable. The RMEs send and receive the digital signal between the Avid HD MADI interface, located above the RME M32s, which in turn connect to a Pro Tools Ultimate 'HDX' PCIe card held within the same metal chassis as the 'RayDAT' card mentioned above. Again, this is connected via an extra long optical Thunderbolt cable to the iMac in the recording studio control room.

Ensure the BNC MADI input has been selected by pressing the 'select' button in the MADI INPUT section. Then ensure that the CLOCK SECTION of the DA has MADI chosen by pressing the 'select' button (on the left) until MADI is selected.

If you are using sample rates higher than 48kHz then you may need to adjust the clock "state". Please see below for more details on advanced configurations.

Using the RMEs with Your Own Laptop

The recording studios were designed to allow you to use your own laptop instead of the provided iMac should you wish. To do this, you must use the RME MADIface interface by connecting your laptop to the USB port labelled MADIFACE on the control room Connectivity Panel. This provides 64 simultaneous input and output channels between your laptop and the RME M32 converters, giving 128 channels of audio over standard USB 2.0.

To use the MADIface interface you need to install the free driver from the RME website. Look for 'MADIface XT / USB / Pro' in the downloads and install the correct version for your Mac or Windows system. Linux systems using ALSA v1.1 and above should work with no additional driver.

When using your own laptop with the RMEs, the digital protocol is MADI, connected over optical fibre. The settings are very similar to the Pro Tools configuration described previously.

How both the RME M32s should look when recording to your own laptop at 44.1kHz

In the image above you can see how the RMEs should look when recording to your own laptop at 44.1kHz. You will also need to ensure that the MADIface configuration matches the M32s using the "Fireface Settings" window which appears upon connecting the MADIface to your computer.

The M32 AD (top box) is operating as the master clock in this instance, meaning that the CLOCK SECTION is showing the sample rate being generated and sent to the M32 DA (bottom box). This is the rate at which your DAW should be configured to run.

The M32 DA (bottom box) handles the conversion of digital audio back into the analogue domain. This requires the most adjustment between different recording setups. First, switch off the synchronisation to ADAT using the 'select' button in the ADAT section; the four SYNC lights should switch off and you can now configure the MADI INPUT settings. Ensure the OPT MADI input has been chosen by pressing the 'select' button in the MADI INPUT section. Then ensure that the CLOCK SECTION of the DA has MADI chosen by pressing the 'select' button (on the left) until MADI is selected.

If you are using sample rates higher than 48kHz then you may need to adjust the clock "state". Please see below for more details on advanced configurations.

Using Different Sample Rates

Once you have configured the RME M32s to the correct settings for your chosen DAW, you may wish to work in a sample rate other than 44.1kHz. The RME M32s offer clock speeds of up to 192kHz, though the most common alternative is 48kHz.

If you intend to use a 48kHz sample rate it is best practice to set the M32s to follow the house clock. Simply set both the AD and DA units to Word Clock by choosing WCK from the CLOCK SECTION. When configuring your DAW, choose the Word Clock or External Clock option.

For other frequencies, the M32 AD (top unit) should always be the device generating the local clock pulse. The M32 units only generate 44.1kHz or 48kHz frequencies, but can clock up to 192kHz by multiplying this signal by two or by four. You choose the multiplier using the STATE option in the CLOCK SECTION. This STATE must be set on both M32 units to work.

Here is an example of a pair of RME M32s setup for recording in Logic at a sample rate of 96kHz

When the STATE options are unlit, no multiplier is set. Double speed (DS) multiplies the clock by two, quad speed (QS) by four. In the image to the right you can see an example configuration of the M32s set for use in Logic, communicating over ADAT to the HDSPe RayDAT PCIe card. The M32 AD (top unit) is generating a 48kHz clock signal and doubling it to 96kHz. The M32 DA (bottom unit) receives the same 48kHz clock signal over ADAT and also doubles it to 96kHz.

The table below shows the full options for different sample rate selection.

Sample Rate
(kHz) 		M32 AD
'CLOCK' 		M32 AD & DA
'STATE'
44.1 44.1 Off
48 48 Off
88.2 44.1 DS
96 48 DS
176.4 44.1 QS
192 48 QS

The STATE setting on both units remain the same regardless of whether you are using ADAT or MADI; you only need to choose which protocol to listen to (either ADAT or MADI) on the M32 DA. Everything else is the same as described in the earlier sections.

Total Mix

Total Mix is the software provided by RME to manage the routing of your outputs and inputs, it allows us to listen back to audio post conversion on the long faders of the desk with almost no latency whilst recording audio on the short faders. It also lets us decide where we might want to route out DAW outputs, so if you were working on a desk with fewer channels you could potentially combine signals to double up on each channel.
