Introduction vii

,QWURGXFWL RQ
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 best p arts of the C ADAC etho s and designed them into a new console dedi cated to the li ve touring, conference and event industry.
The R- Ty pe devel opment from a very early stage took into account the needs and re­quirem ents of t his i ndust ry , with use ful idea s and f e ed-bac k f rom the w orld’s top sou nd compan ies . 24 slo t lig htwe ight mono -coq ue fr ames ca n be lo aded with i nput or out put modul es in any order or configuration allowing for maximum fle xibility when configur­ing for a show or a tour.

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.

2-2 System overview
51516 'XDO#2XWSXW#JURXS#PRGXOHV/#;584
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.
51517 '&#0DVWHU#IDGHUV/#;588
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.
See section 9.3 DC Master fader 8255 for details of the fader module functions and appendix C. Jumpers to select VCA Master for DC master bus coding.
51518 /0&05#0DVWHU#RXWSXW#PRGXOH/#;594
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.
51519 /LVWHQ#DQG#6WHUHR#RXWSXW#PRGXOH/#;638
The R-Type console offers the console operator the choice of two audio monitoring functions. The LISTEN section is for local loudspeaker monitoring and the HEAD­PHONES section is for personal monitoring.
Fo r the LISTEN section, there are two output connectors (XLR) on the rear of the module that are designed to feed the user’s choice of external power amplifiers and louds pe ak e rs . T he ou tp ut l e v el is a dj us te d us ing th e 6 0mm f a der an d t he out p ut le v e l is displayed on a pair of LED-meters. The source selection into the loudspeaker monitoring are: PFL (from input channels), LISTEN (from output modules) and EXTERNAL - which is provided as a convenient input to listen to an external source.
R-Type Revision R2005-2
Syste m ov erv iew 2-3
Each selection has an input trim to adjust the balance of the levels. The output can be DIMmed or MUTEd using t he appr opriate switch.
The HEADPHONE section provides the same three source selections as the Listen section. The monitoring level in the headphones is adjusted with the potentiometer prov ided and can also be MUTEd.

The os cillator section contains a low distortion sine wav e oscillator, a pink noise gen­erator, plus an additional input for an external oscillator - for testing and line-up pur­poses. The signal level meter can be switched to monitor each source. The oscillator section can be routed to channels an d/or groups.
The communications section is equipped with a standard microphone amplifier with phantom power and a high pass filter. The output of the microphone amplifier can be routed to the TALK; LINE and REMOTE bus’, each of which is equipped with a send le v el p ot en tio met er. The assoc ia t ed LE D me te r can b e switched to mo ni t or a n y o f th e communication lin es.
The remote calling section also has a microphone amplifier with phantom power and routing to the LISTEN and TALKBACK bus’. Additional visual signalling and monitor­ing ci rcuits is also included.
The CHECK button, at the top of the module, controls the console SOLO function.
Chapter 11 Osc & Communications 8271 has full details of all the module functions.

The CCM and FCM form the control centre for the R-T ype console system. The CCM handl es the memory and communication functions for the console and the FCM han­dles the fader programming facilities.
Additi on al l y, the CCM co nt a in s cont r ol f unc t io ns f o r: Mast er Mu t es (c ha nn el , o utpu t s, matrix and LCR); send 1 to 8 stereo pairing; EVENT and MIDI programming; module LED illumination control; Littlite illumination control; fan spee d control.
A QWER TY keyboard can be plugged into the rear panel for inpu tting of alpha numeric information for use by master fader displays, and software programming functions. An external computer can be connected to the system via a USB port.
The CCM /FCM combination can be placed in any frame in the console system, but they must always be located together. Only one CCM and FCM are allowed in a sin­gle console system.

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
NOTE:
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.
phase

The a.c.-input connectors on each power supply unit have three conductors: ‘LIVE’ (brown), ‘NEUTRAL’ (blue) and ‘EARTH’ (yellow/green). For safety and electromag­netic compatibility considerations, it is essential that the ‘EAR TH’ conductor is con­nected on all PSUs continuous circuit to the “zero-signal reference potential” point in the building.

CADAC power supply units are designed to run from a minimum of 208V up to a maximum of 260V, 50/60Hz a.c. In many parts of the world, the normal single-phase a.c. supply is 100-127V, this means that the CADAC power supply units must be con­nected across two of the phases in the three-phase a.c. supply, see 3.3.4 Connect-

CADAC 8400 switch-mode power supply units are designed to run from a minimum of 208V up to a maximum of 260V a.c, 50/60Hz.
The 84 00 is rated thus +13V@9 2A, ±18V@44A an d 48V@5A. This is sufficient to supply power to a 3 frame configuration, where 4 frames or more are used, the 8019/ 8020 PSUs should be used, see 3.3.7 Switch-Mode Power Supply Units (8019 &
8020).
The a .c. input is connected to the PSU via a 3-core cable, CMA reference 3183TQ – BASEC approved, rated at 20A.

Connection to a 3-phase outlet is required on sites where the syst em voltage between any one of the phases and neutral is 100-127V and the voltage between any two of the phases is 200-240V. Before c onnecting to an y 3-phase outlet, please refer to a qualified electrician who understands your particular installation and the local safety and wiring regulations. Under no circumstances should the 8400 switch­mode power supply units be operated without the green/yellow safety earth conduc­tor connected to the building safety earth conductor system. Each power unit is equipped with an input supply filter whose reference ground conductor is the chas­sis. Failure to connect the green/yell ow safety earth conductor to the correct earth/ ground building reference is a safety and fire hazard.
1. Connect the LIVE (Brown) conductor on the “system 1” 8400 unit to the phase 1 (L1, RED) terminal on the 3-phase power outlet connec tor.
2. Connect the NEUTRAL (Blue) conductor on the “system 1” 8400 unit.
3. Connect the EARTH (Yellow/Green) conductor on the “system 1” 8400 unit to the SAFETY EARTH (Yellow/Green) terminal on the 3-phase power outlet connec­tor.

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.

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’.
