3. The Hardware
3.1 System Components
A complete system consists of up to four components:
·
crystal Control Surface (essential) – available in five main frame layouts.
·
Compact Engine (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.
crystal User ManualVersion: 6.6.0/28/459
3. The Hardware
3.2 Controls Overview
Each control surface consists of at least one Fader Module (with 4 fader strips) and either one or two Central
Modules depending on the frame size.
Some of the control functionality is fixed (system-defined), while some is programmable by the configuration.
3.2.1 Fader Module (951/41-10)
Fader Module
Each Fader Module provides four identical fader strips, each with an ACCESS key, 100mm manual 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.
Belowthe label display are two large MF Keys (3, 4) with foil-printed labels.
All MF Keys are defined by the configuration.
crystal User Manual Version: 6.6.0/2 9/459
3. The Hardware
3.2.2 Central Module (951/41-20)
Central Modules (left & right)
The 4-fader crystal has one Central Module, while all other frame sizes include two (as shown above).
The two stereo peak and correlation meters (A and B) are defined by the configuration.
On the left module, the 8 Function Buttons (INP, DYN,LIM, etc.) are defined by the system. They provide
access to DSP parameter control, bus assign and snapshot save/recall.
On the right module, the same physical keys operate as MF Keys (17 to 24) with foil-printed labels.
Both modules include two rotary encoders (VCAs1, 2) and more MF Keys (1 to 16) with foil-printed labels.
All MF Keys and VCAs are defined by the configuration.
3.2.3 Programmable Functions
Programmable controls, such as MF Keys and VCA encoders, are defined by the configuration stored on the
Compact Engine. They can be edited using the ON-AIRDesigner software, allowing you to change the operation
as required.
In most cases, the 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.

3.3 Control Surface Variants
4-fader single frame
12-fader single frame
crystal can exist as a single or split-frame control surface.
A choice of five main frame layouts are available, with the option to add an extender module to increase the
fader count or create a split-frame surface.
In total, the control surface can include any number of extenders as long as the maximum number of faders
does not exceed 24.
Each frame connects to the Compact Engine via CANbus, and is powered from its own 12V DC power supply
(included). All frames include CAN IN and CAN OUT connectors for easy daisy-chaining. In each case, the
CAN bus address of a module defines its functionality. Thus, frames can be wired in any order.

3.3.1 Frame Layouts
Five main frame layouts are available plus the 4-fader extender. Note that the 4-fader main frame supports a
single Central Module, while all other sizes include two.

3.3.2 Placement Options
crystal is designed to be mounted on a table top surface.
All connectors are positioned along the top edge, so you must make sure that these are accessible:

3. The Hardware
3.4 The Compact Engine
The 19”/1RU Compact Engine contains the signal processing, control system and routing matrix. It also handles
all audio, control and external Wordclock connections.
3.4.1 Front View
1 Status Display & Menu Control
The front panel display shows local device parameters such as the IP address. You can use the >> and OK
buttons to navigate through the menus.
2 RESET button
Press this button to perform a warm start. The button is recessed to prevent accidental operation.
A warm start will reboot the device. Do NOT perform a warm start while live on air!
3 MADI 1 to 4
The Compact Engine can be delivered with 0, 2 or 4 external MADI ports to connect multi-channel digital audio.
Each port supports 64 bi-directional channels.
The odd/even port pairs (1/2, 3/4) can be configured to operate as main and redundant connections.
4 ETHERNET
The ETHERNET port connects other devices to the Compact Engine control system. Applications include remote
control via TCP/IP; networking to other products; updating firmware and uploading a configuration.
5 CAN
The CAN bus port connects to the control surface frame(s).
6 RS 422
The serial port can be used for debugging. It is usually left unconnected.
7, 8 Expansion Slots x 2 - additional IO
The two expansion slots can be fitted with any of the following IO cards:
·
LINE IO (952/31) - 8 x line level in + 8 x line level out.
·
AES3 IO (952/32) - 4 xAES3 in (with SRC) + 4 xAES3 out (with SRC).
·
MIC/LINE IO (952/36) - 4 x mic/line in + 4 xline level in.
·
RAVENNA IO (952/38) - 2 x AoIP ports, supporting either 8 in/out or 64 in/out with the internal MADI
bridge option.
Cards can be fitted to either slot position, but to use all 64 channels of a RAVENNA IO card it must use the left
slot (7) to support the internal MADI bridge.
IO cards must NOT be exchanged while the frame is powered, as to do so may damage the card and/or
Compact Engine.

3.4.2 Rear View
9 Analog & Digital IO
The following audio connections are always included.
·
HEADPHONE 1 & HEADPHONE 2 - two stereo headphone outputs.
·
LINE OUTPUT- 8 x line level outputs.
·
MIC/LINE INPUT - 4 x mic/line in + 4 xline level in.
·
AES3 INPUT - 4 x AES3 inputs.
·
AES3 OUTPUT- 4 x AES3 outputs.
10 GPIO
This connector provides 8 x GPI (optocouplers) and 8 x GPO (silent and self-healing relays) for local signaling
and switched functions.
11 WCLK IN & OUT
WCLK IN can be used to connect an external sync reference. The sync reference options are MADI, WCLK IN,
AES3 or Internal.
WCLK OUT always provides an output of the current system reference.
12 CASE
The CASE grounding screwshould be used to ground the frame.
13 12V DC & AC MAINS Inputs
Every device comes with dual power feeds: AC and DC. To use the DC input, you will need the external 12V DC
power supply. This is optional and must be ordered separately.
If both inputs are connected, then the two feeds provide main and redundant power.
The Compact Engine MUST be connected to the mains using the power cable supplied with the system.
crystal User ManualVersion: 6.6.0/216/459
4. The Standard Configuration
4.1 Introduction
To make the console easy to operate ‘out of the box’, the Compact Engine is delivered with a standard
configuration. This defines how many sources and summing buses you have, where to connect your audio
devices, the signal processing for each source channel, what functions are programmed onto the MF keys, and
so on.
The standard configuration can be modified using a software application called the ON-AIR Designer. The later
chapters in this manual describe the possible configuration options. For more information on using the tool,
please refer to the "ON-AIR Designer User Guide".
If you are using VisTool MK2, then there is an accompanying VisTool configuration which can be operated using
a standard VisTool license. This is described later in the Operation chapter. For more information on installing
VisTool MK2, and modifying its configuration, please refer to the "VisTool MK2 User Guide".
The standard configuration files are available from the Downloads area at www.lawo.com (after Login). Please
note that there is a separate ON-AIR Designer file for each frame size. The "vistool_crystal" project can be used
with any of the ON-AIR Designer files.

4.4 Default Audio Assignments
The tables which followlist the default audio assignments for the inputs and outputs.
For the inputs, the source assignments are fixed and cannot be changed by the user. Instead, you can choose
which inputs are active in the mixby changing the fader strip assignments on the surface.
For the outputs, the configuration loads the default audio assignments.
