After Sales Modifications
Please be aware that any modifications other than those made or approved by Calrec Audio Limited or their agents, may
invalidate the console’s warranty. This includes changes to cabling provided by Calrec and variations to the recommended
installation as detailed in Calrec documentation.
Modifications to this equipment by any party other than Calrec Audio Limited may invalidate EMC and safety features
designed into this equipment. Calrec Audio Limited can not be liable for any legal proceedings or problems that may
arise relating to such modifications.
If in doubt, please contact Calrec Audio Limited for guidance prior to commencing any modification work.
CALREC Putting Sound in the Picture 15
Installation
In many installations the AC power connectors will not be readily accessible, effectively making the equipment
permanently connected. The installation should be carried out in accordance with all applicable installation rules and
regulations.
Service Personnel
The AC power disconnect devices are the 2 x IEC (IEC60320-1 C13/C14) couplers located at the rear of each unit.
WARNING: The apparatus has a dual power system. It is essential that BOTH AC power IEC couplers are disconnected
to prevent exposure to hazardous voltage within the unit.
Third Party Equipment
Integrating third party equipment into a Calrec system may compromise the product’s ability to comply with the Class B
radiated emission limits set in the EMC (Electro Magnetic Compatibility) standard EN55022.
Calrec Audio Limited can not be responsible for any non-conformities due to use of third party equipment. If in doubt,
please contact Calrec Audio Limited for guidance prior to integrating any third party equipment.
ESD (Static) Handling Procedures
In its completed form, this equipment has been designed to have a high level of immunity to static discharges. However,
when handling individual boards and modules, many highly static-sensitive parts are exposed. In order to protect these
devices from damage and to protect your warranty, please observe static handling procedures, for example, use an
appropriately grounded anti-static wrist band. Calrec will supply an electrostatic cord and wrist strap with all of its digital
products.
All modules and cards should be returned to Calrec Audio Limited in anti-static wrapping. Calrec Audio Limited can
supply these items upon request, should you require assistance. This applies particularly to digital products due to the
types of devices and very small geometries used in their fabrication, analogue parts can however still be affected.
RoHS Legislation
In order to comply with European RoHS (Reduction of Hazardous Substances) legislation, Calrec PCB and cable
assemblies are produced with lead-free (tin/copper/silver) solder instead of tin/lead solder.
In the unlikely event of a customer having to carry out any re-soldering on Apollo, Artemis or Hydra2 hardware, it is
imperative that lead-free solder is used; contaminating lead-free solder with leaded solder is likely to have an adverse
effect on the long-term reliability of the product. Circuit boards assembled with lead-free solder can be identified
(in accordance with IPC/JEDEC standards) by a small oval logo on the top-side of the circuit board near the PCB
reference number (8xx-xxx). The same logo is used on the connector hoods of soldered cable assemblies.
If in doubt, please check with a Calrec customer support engineer before carrying out any form of re-soldering.
ISO 9001 and RAB Registered
Calrec Audio Ltd has been issued the ISO9001: 2008 standard by the Governing Board of ISOQAR.
The award, for both UKAS and RAB registration, is the most comprehensive of the ISO9000 international standards.
Granted in recognition of excellence across design, development, manufacture and after- sales support, the certification
follows a rigorous and thorough review of Calrec’s internal and external communication and business procedures.

Putting Sound in the Picture
SURFACE OVERVIEW
The Summa surface is shown here in its smallest format, 12+8, which includes one 8 fader section with a large TFT
touchscreen (touch display), and one 12 fader section with a large TFT display (meter display). Summa is available in two
larger formats: 24+8 and 36+8. Each have the same 8 fader section with multiple 12 fader panels. All surface sections
of the Summa are described in detail in the following pages.
FIGURE 1 - SUMMA 12+8 SURFACE
22 SUMMA Networked Audio Production System SYSTEM OVERVIEW
CONTROL SURFACE SECTIONS
Fader Strip
Each Summa 12 fader panel is made up of 12 fader strips, each combining a motorised fader, several push buttons and a
small TFT fader display. The image below explains the operation of each button.
FIGURE 1 - FADER STRIP
CALREC Putting Sound in the Picture 23
Fader Display
Each fader strip includes a small TFT display. The image below highlights each icon which can appear on the display.
FIGURE 2 - FADE R D I SPLAY
24 SUMMA Networked Audio Production System SYSTEM OVERVIEW
Control Cell
A control cell combines a small TFT display, an illuminating button and a rotary control. There are two control cells
situated above each fader strip. The function of these control cells varies depending on which control mode you have
selected.
In access mode , all control cells on the surface show EQ and dynamics controls for the currently accessed path.
In function-specific—strip—control modes, the control cells correspond to the faders below them, for example, in pan
mode, each control cell operates the pan controls for the fader below.
FIGURE 3 - CONTROL CELL
CALREC Putting Sound in the Picture 25
Control Modes
Control modes allow you to set how the control cells function across the surface. The two main styles of layout are the
‘strip’ modes, which are function-specific and follow a channel strip style layout (i.e control cells are associated to the
fader directly below them), and access mode, in which all control cells show dynamics and EQ controls for the currently
accessed path. See “Control Modes” on page 44 for more information.
FIGURE 4 - CONTROL MODES
26 SUMMA Networked Audio Production System SYSTEM OVERVIEW
Parameter Adjust
The parameter adjust control combines a rotary control and a push button, and can be used to adjust all touch display
controls—as you tap to select controls on the touch display they are automatically linked to the parameter adjust button
and rotary control. Controls are mapped logically to the rotary control and button; switches and buttons on the touch
display are attached to the physical button, and level controls and menu scrollers are attached to the rotary control.
FIGURE 5 - PARAMETER ADJUST
CALREC Putting Sound in the Picture 27
Console Monitors
Two sets of loudspeakers can be fed from Summa’s console monitor bus, one ‘main’ and one ‘small’ set. There is also
provision for a separate loudspeaker for monitoring the console’s PFL feed. The console monitors section of the surface
allows control of all sets of loudspeakers. The image below explains each loudspeaker control in detail.
FIGURE 6 - CONSOLE MONITORS
28 SUMMA Networked Audio Production System SYSTEM OVERVIEW
Studio Monitors
Summa has three dedicated studio monitor feeds for relaying signals back to the studio floor. This section of the surface
provides level, mute and talkback control for these feeds.
FIGURE 7 - STUDIO MONITORS
Linking Paths
When paths are linked, adjustments to the parameters of one linked path are also made for all other linked paths.
Adjustments are made relatively across all paths, preserving any offsets. The CLEAR button, as shown here, provides a
quick way to clear all path linking on the surface. See “Control Linking” on page 135 for more information.
FIGURE 8 - LINK BUTTON
CALREC Putting Sound in the Picture 29
Surface Layers
The Summa surface has six layers in total, allowing fader-control of 6 times as many paths as there are faders on the
surface. You can switch between layers using the layer selection buttons 1–6 on the surface. When selecting a layer, all
fader positions, button states and control cell states change immediately to reflect faders on the newly selected layer.
FIGURE 9 - SURFACE LAYERS
Surface Reset
The surface reset button is recessed to avoid it being pressed accidentally. If a reset is required a pointed implement
should be used to push it. Two types of surface reset can be performed using the surface reset button:
• If a non-critical error occurs, such as a user interface crash or freeze, press the reset button and release within 5s.
The surface will reboot from local memory which is stored on an internal SD card. The reset LED will flash green
throughout.
• If a more serious error occurs, such as the surface not booting correctly or a corruption of the user interface, a full
reprogram should be performed: Press and hold the reset button and release after 5s. The surface is reprogrammed
from memory stored within the core processing rack. The LED will flash Red throughout.
