1.2 DC2020 Introduction

Typical-Use Environment

The console is designed to be used with a multi-track tape machine or any LTC/MIDI Ti mecode genera ting device. Ti mecode is read by the console to provi de the tim e base f o r the Mi x Automation.

Good Housekeeping

Shutting-Down The Console

The program which runs the automation system within the console is held on the hard-di sk drive. New re leases may be loaded onto the hard-disk dri ve via the fl oppy drive .

The DC2020 uses an APS520 Powe r Supply Unit. Not e that this powe r supply has powerful cooling fans: it is therefore advisable to install it away from the control room.

We strongly reco mmend tha t you take regular bac kups of your har d disk. This is done by selecting the appropriate backup option from one of the following

screens: Studio Utilities, User Utilities, Proj e ct Uti liti es or Titl e Util it ies.

It is important that you do not switch the power supply off without first shutting down the automation system correctly.

This is done by se lecting the Shutdown Console fro m one of the followi ng scree ns: Studio Uti liti es, Use r Uti liti es, Proj e ct Uti liti es or Title Ut ilit ies.

The Shutdown Console utili ty wri tes t he c onten ts o f RAM to di sk, c loses a ll of the open disk fi le s and then prompts you to swi tch t he console off.

Precautions and Safety Instructions

General Precautions

Caution!

Handlin g and Tra nsp ort

Power Supplies & cables

Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions where it is likely to be subject to vibration, dust or moistu re. Do not use any liquids to clean the fascia of the unit: a soft dry brush is ideal. Use only water or e thyl alc ohol to cl ean the t rim and sc ribble strips. Ot her solve nts may cause dama ge to pa in t or pl a sti c pa rt s.

Avoid using the console close to strong sources of electromagnetic radiation (e.g. video monitors, highpower electric cabling) : this may cause degradation of the audio quality due to induced voltages in connecting leads and chassis. For the same reason, alwa ys sit e the powe r supply awa y from the unit .

In all cases, refer servici ng to qualified per sonnel.

The console is suppli ed in a wooden cra te. If it is ne cessa ry to move it any dista nce after installation it is recommended that this packing is used to protect it. Be sure to disco nne ct a ll c ab ling be fo re mo ving. If the con sole i s t o be reg ula rl y mo ved we recom mend tha t it is inst alle d in a foaml ined fl ightc ase. At al l times av oid ap plying excessive force to any knobs, switches or co nnectors.

Always make sure that the power supply unit (PSU) has been set to the same voltage as the mains supply

Signal Levels

Warning!

Always use the power supply and cable supplied with the mixer: the use of alternative supplies may cause damage and voids the warranty; the extension of power cabl es m ay re sult in ma lfu nc tion of t he mixin g co nsol e.

Always switch the power supply off before connecting or disconnecting the mixer powe r cable , rem ovi ng of instal ling module s, and ser vicing. In the ev ent of an electrical storm, or large mains v oltage fluctuati ons, immediate l y switch off the PSU and unplug from the mains.

Always ensure that you use the correct PSU for your mixer. The DC2020 uses a APS500A power supply.

It is important to supply the correct input levels to the console, otherwise signalto noise ratio or distortion performance may be degraded; and in extreme cases, dama ge to the inter na l ci rc ui try may resu lt . Likewise, on all bal an ce d i nput s av oid sources with large commonmode DC, AC or RF voltages, as these will reduce the availa ble signal range on the inputs. Note that 0dBu = 0.775V RMS.

The microphone inputs are design ed for use with ba l an ced low im pe da nc e (150 or 200 ohms) mic rop hone s.

2.4 DC2020 Installation

Caution!

DO NOT use unbalanced microphones or battery powered condenser microphones without isolating the +48V phantom power: degraded performa nce or damage to the microphone ma y result.

The sensit ivity of the XLR inputs i s variabl e from -2dBu to -70dBu and + 10dBu to

-20dBu in two range s (for +4dBu at the Mix outputs). The maxi mum inp ut level is +28dBu.

The Hi-Z inputs have a sensitivity variable between +10dBu and -20dBu. The maximum input level is +30dBu.

The main outputs of the console (stereo mix, groups, wedge and mix and group insert sends) are balanced at a nominal level of +4dBu, with a maximum output level of +26dBu.

The inp ut insert sends a nd dire ct ou tputs a re ground compe nsat ed at a nominal level of -2dBu, with a maxim um outp ut lev el of +20dB u.

All externa l inputs and m ix and group inse rt returns have a nominal leve l of +4dBu, and a maximum input leve l of +26dBu .

Input insert returns have a nominal level of -2dBu, and a maximum input level of +20dBu.

Installation

The DC2020 is designed for reliability and high performance, and is built to the highest standards. Whilst great care has been taken to ensure that installations are made as troubl efree as possible, car e taken at this sta ge, followe d by corre ct setting up will be rewa rd ed by a long l ife and reliable ope ra t ion .

Wiring Considerations

Power Supply (APS520)

Warning!

A For optim um perfor mance it is essent ial for the earthi ng system to be clean and noisefree, as all signals are referenced to this earth. A central point should be decided on for the main earth point, and all earths should be ’star-fed’ from this point. It is recommended that an individual earth wire be run from each electrical outlet, bac k to the syst em star p oint to pro vide a sa fety e arth refere nce for each piece of equi pment.

B Install separate mains outlets for the audio equipment, and feed these indepe nde ntly from any oth er equ ipment.

C Av o id loc a ti ng m a ins d ist rib ution boxes ne a r audi o e qui pm ent, especia ll y ta pe record er s, whi c h ar e ve ry sensi ti ve to ele c tr om ag ne ti c fi e lds.

D Where possible ensure that all audio cable screens and signal earths are connect ed to ground on ly at their sou rc e.

Always ensure that you use the correct PSU for your mixer. The DC2020 uses a APS520 power supply.

Before switching on your DC2020 console, check that the mains voltage selectors on the power supply unit is set to the correct mains voltage for your area, and that the fuse is of the corre c t ratin g and typ e. This is cle ar ly m ar ke d on the ca se of the power suppl y. Do not repl ac e the fuse with any othe r ty pe , as t his c ou ld b ec om e a safety hazard and will void the warranty.

2.6 DC2020 Installation

Connections

Wiring conventions

The DC2020 use s two different types o f audio connec tor: 3-pin XLR and 1⁄4" 3-pole jacks. The latter are used in seve ral co nfi gura t ion s, as shown below (not e that the patchbay versions have no 1/4" jack sockets except for the SMPTE In and Out connections). The DC2020 also uses DIN, D-type and BNC connectors: these are shown on th e ne xt pa ge .

8. Once the DC2020 emulation is running, choose Select Port... from the Settings pull down menu. Selec t the PC port to which your PC-t o-Consol e cable is connected e.g. port 1.

IMPORTANT:

It is impo rtant t o understa nd th at the Windows / Maci ntosh i nterfa ce is an em ulation of the DC2020 touch sensitive screen. Therefore, the location of a mouse click on the computer screen is translated into a press on one or more cells of the touch sensitive screen.Consequently a touch pad in close proximity to the mouse click may respon d, even though t he mouse pointer is not strictly wi thin the box. This m ay run contrary to expectations if one is familiar with Windows or Macintosh applications.
