Using scene memories
What are scene memories
The current channel settings of controllers 1–4 can be stored as a scene and recalled when desired. These settings are called "scene memories."
How scene memories are associated with M-48 memories
If an M-48 unit is connected to the Digital Snake system, you can associate scene memories with M-48 memories. An M-48 memory can be stored at the same time that you store a scene, or an M-48 memory can be recalled at the same time that you recall a scene.
Notes regarding scene memories
* Scene memories are saved within the S-4000 RCS project.
* An S-4000 RCS project can contain one hundred scenes.
* Scene memories can be stored and recalled even if a connection has not been established.
* Storage and recall of M-48 memories occurs within the M-48's internal memory.
* If the M-48 is not connected to the system, M-48 memories will not be stored or recalled.
* Scene memories doesn't store/recall the S-4000M's input/output setups (p. 22).

Editing the S-4000M's Input/Output Settings
The S-4000M has a Merge patchbay and an Output patchbay (Output patchbay supports S-0808 8x8 1/O UNITS only). You can edit the S-4000M's Merge/Output patchbays using S-4000 RCS to change input/output assignments.
Merge Patchbay
This merges the inputs of the REAC slave units (REAC ports 1–4) into the channels being sent to the REAC master unit (REAC port A).
Output Patchbay
This assigns the channels being sent from the REAC master unit (REAC port A) to the outputs of the S-0808 units (REAC ports 1–4).
* You cannot edit an S-4000M's input/output settings when the S-4000M is set to the THRU mode.
Storing Input/Output Setups
The S-4000M input/output setup is saved to internal memory. The S-4000M configuration window loads and displays the setup from the connected S-4000M. You can save and load S-4000M input and output setups as a computer file (p. 30)
* S-4000M's input/output setups cannot be saved as part of scene memory.

Splitting Merged Inputs (S-4000M's Split Function)
By using the S-4000M's Split Function, you can split the merged inputs (being sent to the REAC master device) to REAC port 4. It is very convenient when splitting to a monitor console or a multi-channel recording system.
* When a REAC splitter (like the S-4000D) is connected to the S-4000M's REAC port A, the signal from the REAC master device is split.

Notes About the S-4000M's Split Function
* You can connect a REAC slave device to S-4000M's REAC port 4 via a REAC splitter (like the S-4000D). In this case, the physical inputs of the REAC slave device operate normally but all merged inputs being sent to the Master will being sent out from the physical outputs.
* If an M-48 is connected to the S-4000M's REAC port4, it is not possible to manage/setup the M-48 from the M-48 Manager window.
When a REAC splitter (like the S-4000D) is connected to the S-4000M's REAC port A, the signal from the REAC master device is split.
Using S-4000M's Split Function
- Open the S-4000M Con guration window.
If the "Split merged inputs" button is checked, then the S-4000M's split function is already turned on. The following steps will not be necessary.
-
Disconnect the REAC cable connected to REAC port 4 on the S-4000M.
-
Click "Split merged inputs"
A confirmation message box opens to confirm the operation.
- Click [OK]
The display mode of S-4000M changes. The signal of merged input channels are split and sent out the device connected to REAC port 4.

Managing the M-48 Live Personal Mixer
What is the M-48 live personal mixer
The M-48 is a live personal mixer that allows each musician to create their own mix. By unifying the professional monitor mix created by the mixing engineer with the personal mix created by each musician, the M-48 provides a monitoring environment that's ideal for the musician.
40-channel mixer

The M-48 provides a REAC port that is able to receive up to 40 channels of digital audio via REAC. The digital audio sources are mixed by the internal 40-channel mixer for monitoring via headphones or monitor speakers.

The sources 1–40 being input via REAC are mixed by the M-48's 40-channel mixer. Settings and operation of the 40-channel mixer are shared between the mixing engineer and the musician.
* The 40 digital audio source channels being input via REAC to the M-48 are referred to as sources 1–40.
Settings by the mixing engineer
These settings are made by the mixing engineer from the V-Mixer or the PC.
1 Source level / pan settings
These settings specify the LEVEL, PAN, and AUX switch settings for sources 1–40.
2 Source assign settings
These settings assign sources 1–40 to sixteen stereo groups for operation on the M-48.
Operations performed by the musician
These operations are performed by the musician on the M-48 unit.
3 Group mix
VOLUME, PAN, REVERB SEND, and 3-BAND EQ can be adjusted for each stereo group created by the source assign settings.
* The group mix can also be viewed and edited from the V-Mixer or PC.

The M-48 provides two sets of output: PHONES and LINE OUT.
1 PHONES
REVERB, AMBIENT MIC, and AUX IN are mixed into the MAIN bus, then BASS, TREBLE, and LIMITER are applied to the mix which is then output from these ports. This is used for headphones or in-ear monitoring.
2 LINE OUT
As the LINE OUT source, you can choose either PHONES (the signal immediately before PHONES VOLUME), MAIN bus, or AUX bus. This is used for a floor monitor or for two-channel recording. Since a low-pass filter is provided on LINE OUT, it can also be used to output just the low frequency range to a floor monitor or tactile transducer.
Memory functionality
The M-48 has 16 memories, and allows mixer settings to be stored or recalled. Memories 1–16 can be manipulated from the M-48 itself or from the V-Mixer or PC.
Connections with an S-1608 system
Note when connecting M-48 units (S-1608 system)
* The S-1608 system must be using system software version 2.0 or later.
If S-4000 RCS is connected to an S-1608/S-0816 that is operating as a split REAC device, it will not be possible to make M-48 settings.
* Up to four S-4000D units can be connected in series. Approximately 200 microseconds of propagation delay will occur for each unit.
* Up to sixty-four M-48 units can be connected to each Digital Snake system.
* In order to maintain the transmission quality of the digital REAC signal, use fully approved CAT5e Ethernet cable such as the 20 meter or 100 meter REAC cables (SC-W20F / SC-W100S / W100S-R; sold separately).
Note regarding the ordering of M-48 sources
The order in which channels are shown for controllers in the S-4000 RCS window may differ from the order of the M-48 sources.
S-4000 RCS window

M-48 Source Lev/Pan window

This occurs because the REAC master device and REAC slave device handle channels in a different way than a split REAC device (M-48) handles channels.
On an S-1608 system, this discrepancy will occur in the following case.
- When the S-0816 is the REAC master device

To check the version, refer to "Viewing version info for the Digital Snake" (p. 19).
Example 1: S-1608 + M-48 (16 sources)
This is an example in which M-48 units are connected to the S-1608 (REAC master). A total of up to sixteen channels of direct out and bus out signals from the console can be input.

Operations using the keyboard
| Key | Operation |
| [←] ↗ [ | Selects a group |
| [shift] + [↑/ [ ] → | Selects a group (in 8-group steps) |
| [↑] ↘ [ | Selects a source |
| [shift] + [↑/ [ ] ↓ | Selects a source (in 10-channel steps) |
If the "Mix only assigned sources" on the Mix Option ② not checked, a source that is not assigned to any group will also be mixed to the M-48's MAIN buses, and that source cannot be controlled from the M-48's panel.
In some cases you may want to include a source without being able to control it from the M-48's panel:
1. For talkback communication
The mixing engineer can have talkback as one of the sources, leaving the source level up but not assigned to a particular group (knob). This way the talkback signal is not controlled by any of the M-48 knobs yet still can be heard by the musician.
2. To provide simple control
E.g., The mixing engineer can provide just vocal control for a vocalist via source assignment. All other sources are not assigned to any groups (knobs) and can be provided as a fixed mix. The vocalist just adjusts the volume of their voice alone.
Clearing the source assign settings
- Open the M-48 Source Assign window
- Click the [Clear] button.
A message box will ask you to confirm the operation.
