3. The Hardware
3.1 System Components
A complete system consists of up to four components:
· ruby Control Surface (essential) – available in single or split-frame configurations.
· DSP Core (essential) – all audio interfacing, routing, control and signal processing.
· VisTool MK2 (optional) – runs on an external PC to provide real-time displays and touch-screen control.
· Key Panels (optional) – a range of panels offering additional keys and talkback control.
This document describes the ruby control surface.
For more information on other components, such as the DSP Core or VisTool MK2, please refer to the manuals
for those products.

rubyUser ManualVersion: 6.0.0/410/82
3. The Hardware
3.2 DSP Core Compatibility
The ruby control surface is compatible with the following DSP Core products:

rubyUser Manual Version: 6.0.0/4 11/82
3. The Hardware
3.3 Controls Overview
Each control surface consists of at least one Fader Module (with 4 fader strips), a single Central Module, and up
to 6 additional Central Modules running in monitor mode.
Some of the control functionality is fixed (system-defined), while some is programmable by the configuration.
3.3.1 Fader Modules
Fader Module
Each Fader Module provides four identical fader strips, each with an ACCESS key, 100mm motorised fader,
backlight and label display.
The upper section includes a rotary control and four small MF Keys (1, 1a, 2, 2b). Their functions are labeled by
the OLED displays.
There are then three large MF Keys (3, 4, 5) with foil-printed labels.
All MF Keys are defined by the configuration.

rubyUser ManualVersion: 6.0.0/412/82
3. The Hardware
3.3.2 Central Modules
The Central Module (full mode)
Central Module (monitor mode)
Each control surface must include one Central Module. If additional Central Modules exist, then these must run in
monitor mode.
The Central Module (full mode)
The upper section includes four sets of rotary encoders and small MF Keys which interact with the 12 Function
Buttons: INP, DYN,LIM, etc. Their functions are labeled by the OLED displays. When none of the Function
Buttons are active, the controls are defined by the configuration (MF Keys 29 to 42 and VCAs 3 to 6). When a
Function Button is pressed, then the controls provide DSP parameter control, bus assign, system options and
snapshots. To the left are two large MF Keys (45 & 46) with foil-printed labels.
In the lower section are more large MF Keys (1 to 28) with foil-printed labels, and two rotary encoders (VCAs1, 2)
which are labeled by the displays.
All MF Keys and VCAs are defined by the configuration.
Central Modules (monitor mode)
Physically, these modules are identical to the full mode Central Module, but they provide slightly different
functionality.
Each module provides the same programmable MF Keys and VCA encoders, but in the upper section the 12
Function Buttons are NOT supported. This means that there is no access to DSP parameters, bus assign,
system options and snapshots. All controls are defined by the configuration. Note that the 12 Function Buttons
cannot be programmed by the configuration and, therefore, will remain blank.

rubyUser Manual Version: 6.0.0/4 13/82
3. The Hardware
3.3.3 Programmable Functions
Programmable controls, such as MF Keys and VCA encoders, are defined by the configuration stored on the
DSP Core. They can be edited using the ON-AIR Designer software, allowing you to change the operation as
required.
In most cases, the large MF Keys are labeled by foil-printed labels and, by default, the control surface ships with
the labels for the standard template functions. If you change the MF Key functionality, then you will need to
exchange the foil-printed labels. Printed sheets with the most common labels are included with each control
surface frame.

3. The Hardware
3.4 Control Surface Variants
8-fader single frame
12-fader split-frame
ruby can exist as a single or multi-frame control surface.
A choice of four main and five extender frames are available. Frames can be combined to increase the fader count
or create a split-frame surface. Each frame connects to the DSP Core via CAN bus, and is powered from its own
12V DC power supply (included). All frames include CAN BUS IN and CAN BUS LINK OUT connectors for easy
daisy-chaining.
In total, a single control surface can include any number of frames as long as the maximum number of faders
does not exceed 60.
One of the frames must include a Central Module but this can exist only once. Therefore, any additional Central
Modules will run in monitor mode. A single control surface can include up to 6 "monitor mode" Central Modules.
3.4.1 Main Frame Layouts
Four main frames are available. Each one includes a Central Module:
4-fader
8-fader
12-fader
16-fader
3.4.2 Extender Frame Layouts
Five extender frames can be added, either to increase the fader count or create a split-frame console.
4-fader extender
8-fader extender
12-fader extender
16-fader extender
Central Module ext.

rubyUser Manual Version: 6.0.0/4 15/82
3. The Hardware
3.4.3 Split-frame Configurations
By combining different frames, you can easily create a surface suitable for multiple operators.
In the example below, the surface includes three frames:
· 1 x 8-fader main frame (for the Assistant Operator)
· 1 x 12-fader main frame (for the Main Operator)
· 1 x 4-fader extender frame (for the Presenter)
By setting the correct CAN bus addresses, the order of fader strips and position of the Central Module is
flexible. In our example, the Main Operator's station can house the Central Module plus fader strips 1, 2, 3, etc,
even though its CAN bus is wired after the Assistant's station.
Multi-frame Configuration
A single control surface can support up to 60 faders, a single Central Module and up to 6 monitor mode
Central Modules.

rubyUser ManualVersion: 6.0.0/416/82
3. The Hardware
3.5 Placement Options
Each frame is available in one of three versions to provide different placement options. Note that the version must
be specified at the time of ordering; there is no possibility to convert the frame later.
Table Top
Countersunk
Countersunk Short
The differences in construction are:
· Table Top - designed to be mounted on a table-top surface. This version includes a leather front buffer
and stylish side/rear profiles.
· Countersunk - designed to fit flush within your studio furniture. This version comes with different front,
rear and side profiles.
· Countersunk Short - the same as Countersunk but with shorter side profiles and no upper cover plate to
hide the cables (i.e. the rear panel connectors will be visible).

rubyUser Manual Version: 6.0.0/4 17/82
3. The Hardware
3.6 Accessories
Each control surface frame ships with the following additional items:
· 1 x external 12V DC power supply - to power the frame.
· 1 x 2m IEC power cable (country-specific) - to connect mains to the 12V DC power supply.
· 1 x 3m RJ45 cable - to connect the CAN bus from the surface to the DSP core or another frame.
· Printed sheets with a selection of foil printed labels - to label the MF Keys.
If your control surface consists of multiple frames, then you will receive one set of accessories per frame (as every
frame requires its own power, CAN bus and MF Key labels).

Unpacking
Each frame is delivered in its own box with all included accessories.
Please check the contents of the shipping boxes, and in the event of any transport damage, contact your local
Lawo representative or email [e-mail].
Please take note of the Technical Data label, which includes your serial number, located on the underside of
each frame. Write down the serial number for your records BEFORE mounting!
Dimensions and Weight
The dimensions and weight of the frame depend on its size and version: table-top, countersunk or countersunk
short. Drawings for 8-fader frame versions are included in the Appendices. Drawings for other frame sizes are
available from the Download-Center at www.lawo.com (after Login).
Temperature and Cooling
The control surface is designed for normal studio installation and needs no special air conditioning.
Power Consumption & Electrical Voltage
Please see the 12V DC Power Supply appendix.

4. Installation
4.2 Installing Countersunk Frames
Countersunk
Countersunk Short
Countersunk frames are optimized for easy countersunk mounting.
The frame has rounded-off edges so that it will fit smoothly into holes cut by a wood milling machine.
For the countersunk (regular) version, all cables can be hidden in the cable tray and connected to the console
inlets from the open underside of the tray.
For the countersunk short version, the table must be designed to provide a small opening in order to properly
cable the device.
All countersunk frames have flat side parts without edges. Therefore, the installer must provide some kind of
support onto which the surface will rest.
Please see the dimension drawings for details.
