CADAC would like to thank y ou for purchasing this R-Type console which will bring
many trouble-free years for you to enjoy.
The CADAC R-Type live production touring console is designed to be used as a
Front of House Board or as a Monitor Board. It offers a comprehensive range of features that vastly support and enh ance the job of the Sound Engineer and represents
the ul timate choice for the live touring environment as well as for theatres a nd fixed
installations. The R- Typ e mixing console is entirely modular and fully user configurable, at the same time offering legendary CADAC sound quality and reliability. The
compact light-weight design makes it easy to handle, thus allowing rapid load-in and
load- out for touring applications.
The standard R-Type frame si ze encompasses 24 positions of which a maximum of
16 ma y be bussed toge ther to give a total of 384 spaces where 3 63 may be dedicated mono or stereo inp ut channels. There are 16 pairs of sends for each input;
sends 1 to 8 may be switched between mono (16 sends) and stereo (8 sends).
Sends 9 to 12 and 13 to 16 may be configure d as 8 mono sends or 8 conventional
stereo groups receiving information from the main module pan pot. Direct routing can
be performed to matrices 13 to 16. In addition to a stereo bus, both channels also
incorporate a left, centre and right bus which may be used either as a stereo bus with
separate centre level or with full L-C-R panning. The mono channel has a level controlled direct output.
All modules can be upgraded to incorporate motorized faders.
The module width for the CADAC R-Type is only 35mm, contributing to a compact
footprint and a reduced overall width for improved ergonomics and feature accessibility.
This manual provides information on the installation of an R-Type console and
includes functional descriptions of the modules with enhanced automated functi ons.

CADAC is renowned world-wide for their state-of-the-art theatre consoles. The
CADAC sound and bui ld quality, along with extensive features and automation has
made the company a hou sehold name in t he theatres in London’s West End, Broadway in New York and most major theatres throughout the world. Manufacturing arguably the best mixing consoles in the world, however, also comes at a price.
For a long time, the traditio nal “rock’n’roll” touring sound and hire companies and engineers have been asking for the same quality at an affordable price, with specifications and features more suite d to general live perf ormances. We have now taken the

Mixing consoles consist of a number of input channels and output groups with associated faders, moni toring and control functions - organised in a way to allow the op erator to do the particular job that the console has been designed to achieve. When
module positions are fixed in relation to the frame structure, various operational compromises occur during the life of the console. The R-Type console system allows the
owner or operator to move any m odule into any frame position and to change the
numbe r of fr ame s ass oc ia te d wit h the syst em to inc rea se or decr ea se th e numb er of
input channels and output groups t o meet the needs of a particular project. The
number of inputs, output s, faders and control functions can be varied during the life
of the console, extending the system as work loads increase, and/or to change the
function of the console (for example, to change from FoH configuration to monitor
layout). Experience gained with our “J”, “F” and “M-Type” series consoles has shown
that this type of structure extends the useful life of the mixer by at least one order of
magnitude.
Each R-Ty pe frame has 24 module positions (slots) and there can be as many as 16
frames in any one console system. Each frame has provision f or main and bac k up
power supply inputs and any two adjacent frames have full audio bus and control
function interco nnection on a single multi-way bus loom. Digital control func tions are
automatically mapped on power-up.
The standardised frame wiring provides a total o f 55 balanced busses. Thus a fully
equip ped console syst em can have 32 sends - 16 of which can be switche d as 8
stereo sends for in-ear monitoring or stereo FX applications; 16 m atrix sends; simultaneous L-C-R and stereo outputs; stereo monitoring and PFL. Standard (and
optional motor) channel VCA faders can access up to 16 V CA master fade rs and 16
mute groups. Additional MIDI, EVENT and alpha-numeric display functions for master faders can be programmed and stored in 128 user memo ries (cues) associated
with the CCM.
Extended programmable functionality will be offered, using an external PC (via USB
ports on the CCM) running SAM, at a later date.

Both mono and stereo modules are available. The modules have balanced insert
ports (send and return connectors); four band parametric EQ and high-pass filter selectable pre or post insert; balanced direct output - selectable pre or post fader.
Full details of the functionality offered on these mo dules is discuss ed in chapters 7
Mono Input Channel 8241 and 8 Stereo Input Channel 8231. Also see Appendix D.

51515&KDQQHO#IDGHUV/#;579#PRQR/#;569#VWHUHR1
Both mono and stereo VCA channel faders are available to control the input channels. Each fader has an input level meter (with dual input meters on the stereo) and
DC master/Mute group display.
Full details of the f unctionality offered on these modules is discussed in sections 7.3
Each of the output modules provides two identical OUTPUT channels, that can be
used as either a ’stereo pair’ or dual mono format, and additionally a 16-way level
controlled MATRIX output. The left section of the module controls the A send. The
right section of the module controls the B send.
Up to 16 output modu les may be specified per c onsole and can be placed anywhere
in the multi-frame console structure (they do not need to be placed adjacent to each
othe r, or even in the same frame). Visual monitoring of output levels is provided on
LED bar meters and audio monitoring is provided by pressing the required LISTEN
button on the Output (see 2.2.6 below).
The master faders of either the send group or the matrix level can be controlled from
a selected DC master fader by switching on the appropriate VCA and assignment.
Additionally an external signal may be mixed with either send output by using the
INJECT function. Pr e fader balanced insert ports are provided on all three outputs.
The module mix bus coding for the Output and Matrix is manually selectable using 8way and 4-way jumpers.
See chapter 9 Outputs and Matrix 8251 for details of the module functions and
appendix B. Jumpers to select Output and Matrix for mix bus coding.

A maximum of 16 DC master f aders may be included in the console system. Each
master fad er must be mounted direc tl y be low an ou t p ut gr ou p mo dule, but outpu t
group/master fader combinations may be placed in any of the console system
frames, as suggested in 2.2.3 above. LED assignment displays are fitted to each
master fader. When the “VCA” swit ch is selected on a send or matrix sect ion of a
group module, the LED bar on the left side of the master fader directly below the
module indicates which of th e DC master faders has control of the sel ected group
module fader.

This module provides the amplifier s for the L-C-R outputs, together with master faders and output level metering. All three mast er faders may be put unde r VCA control
of a standard channel V CA fader, which must be located directly below the module.
An external sign al may be mixed with any of these outputs by using the INJECT function.
Audio monitoring of each output is accessed by pressing one, or all three LISTEN
but tons (see 2.2. 6 below).
Full details of the module functions are discussed in chapter 10 L-C-R Output 8261.

The R-Type console is no rmally supplied with the model 8 400 Power Supply Unit.
Each 3U x 19” rack mount power unit supplies all 4 voltages required by the R-Type
console. A single 8400 PSU will power 3 fully loaded R-Type frames.
For console configurations with 4 or more frames, the 8019/8020 systems

must be used, see 3.3.7 Switch-Mode Power Supply Units (8019 & 8020).
Cadac consoles are designed to allow the use of two independent power supply systems in a redundant configuration – “main” and “backup”. Both power supply unit s
are used to power th e console system, so that under normal condit ions, the ‘load’ is
shared equally between the “main” and “backup” PSU. If a fault occurs in one of the
power units (causing it to ‘shut-down’), the remaining power unit will power the console (see fig. 3-11).
Designate one power supply unit as “PSU 1" and the other as “PSU 2". PSU 1 and
PSU 2 should be connect ed to the same
possible. In situations where it is necessary to provide a separate ‘feed’ to each PSU
syste m , make sure that the cable lengths are the s ame. This is to minimize any
induced a.c. power input noise by ensuring that the “EARTH IMPEDANCE” is the
same for both PSU-syst ems.

designed to run from a minimum of 208V up to a maximum of 260V a.c, 50/60Hz.
The 80 19 “18 V ” uni t is r a te d at 10 0A per r a il an d the 8 020 “1 3V” un it is rat ed at 100A.
The 80 19 ±18v unit and the 8020 +13v/48v unit are based on two PowerOne PSUs
each with additional circuitry as shown on CADAC drawings C3.8393 (8019) and
C3.8392 (8020).
The a.c. inputs are connected to the PSU s via two 3-core cables, CMA reference
3183TQ – BASEC approved, rated at 20A.

If replacing a switch-mode pow er supply unit is required, please note the following:
Make sure that the power supply system’s power switches are in the position
■■■■
OFF and disconnected from the mains.
The work should only be carried out by a suitably qualified electrician.
■■■■
Be careful to observe correct polarity w hen connecting the new PSU.
■■■■
Note that a console m ust never have one voltage withou t the ot her, for ex ample
■■■■
+18V must never be fed into the console without -18V.
When switching the power supply system back ON after replacement has taken
place, make sure that both LEDs on the front of the PSU-system come on. If only
one LED comes on, let go of the ON push-button immediately. Failure to do so may
lead to fire hazard and major damage to the console.

Each 8019/8020 switch-mode power supply provides the following outputs: 13v,
±18v and 48v. Each PSU is fitted with a front panel mounted 9-way 'D-ty pe’ connector labelled ‘Connections for Remote Start’. If a remote start facility is used, Power
Failure and Over-Temperature LEDs may also be fitted with the remote start
switches if required.
Fig 3-17 and 3-18 shows the circuit for starting up a “sys tem” with a single switch.
This has proved to be the most popular method of connecting the remote start facility. This circuit can easily be extended to provide a single switch remote for all four
PSUs if required.
NOTE:
The remote start s witch must be a ‘momentary’ type. You can use 3 separate sin-
■■■■
gle pole switche s for each Power Supply to turn on 13v,±18v and 48v outputs of the
PSU al ternatively use one single pole for the w hole lot.
The remote switch(es) must be mounted on a metal panel.
■■■■
Use shielded cable for the remote switch wiring.
■■■■
The 9-way ‘D-typ e’ free plug must have a conductive shell. This is to ensure that
■■■■
the cable shield connects directly to the PSU unit chassis.
Connect the cable shield to the metal panel where the remote start switch(es) are
mounted.

CADAC consoles are designed t o work continu ously with two power supply systems
- ‘main’ and ‘backu p’. The ‘main’ power supply un it is designated ‘System 1’. The
‘backup’ power supply unit is designated ‘System 2’
On each power supply, turn all AC input switches to the ON-position.
Start th e PSUs (in one PSU system) simultaneously, by press ing and holding the
START-buttons until yo u hear the relay click. The CCM will cycle through its self-test
routines and any Master Mut e switches pr eviously selected will be set ON, thus protecting external equipment from possible DC pulses when the ±1 8V PSUs are
started.
Repeat for PSU system 2. If you cannot start the PSUs simultaneously, start the 13V/
48V first. However, do NOT operate the console for long periods without all power
lines on.

computer has complet ed its boot-up routine, then...
Switch to PC2 on the CCM and power-up the second computer and wait until it
■■■■
has completed its boot-up routine.
Once both computers have booted correctly, they should allow the keyboard and
monitor to be switched back and forth without problems.
If the overall cable length for the keyboard and monitor are very long (greater than
5m), it may be necessary to use a keyboard and a monitor booster unit to retain keyboard reliability and a clean monitor display.

7+RZ#WR#XVH#WKH#507\SH
This se ction of the manual provides instructions and information on how to use the
R-Type and may be seen as a pra c tical guide as to how specific procedures are carried out.
The very nature of the R-Type is such that its flexibility allows for several ways to
achieve the same end result. To avoid confusion, this means that in this section you
will learn how to carry out certain procedures to achieve a desired outcome. This
does not, however, imply that the same outcome cannot b e achieved by taking a different route.
In order to assist you in the most effective way to quickl y become familiar with the
operation of the R-Type, we recommend that you initially follow the directions given
belo w and as you gain experience you may well f ind that alternative routes suit your
work practice better.
The directions given assume that the power supplies are in position ON, the buttons
fo r 13V, 18V and 48V ar e pressed and th at the console is in its default condition.
Preferably, the CCM memory should be cleared and finally, the display on the CCM
should read ‘Welcome to the R-Type’.
