Page 7: Introduction
ODUCTION Welcome Thanks for purchasing a UREI by Soundcraft 1603/1605 mixer, we hope you get just as much joy from using it as we got from designing it. The UREI by Soundcraft engineering team have 30 years experience in progressive audio design and take the utmost pride in the way we develop and manufacture products. -
Page 8: General Precautions
General Wiring Procedures To take full advantage of the excellent signal to noise ratio and low distortion of Soundcraft consoles, care must be taken to ensure that incorrect installation and wiring does not degrade the performance of the desk. Hum, buzz, instability and Radio Frequency interference can usually be traced to earth loops and inferior earthing systems. -
Page 9: Initial Wiring Considerations
INITIAL WIRING CONSIDERATIONS For optimum performance, it is essential for the earthing system to be clean and noise free, as all signals are referenced to this earth. A central point should be decided on for the main earth point system, and all earths should be 'star fed' from this point. It is common electrical practice to `daisy chain' the earths to all electrical outlets but this method is unsuitable for audio installations. -
Page 10: Points To Remember
POINTS TO REMEMBER When using balanced connections use good quality twin screened audio cable. Check for instability at the output. Always connect both conductors at both ends, and ensure that the screen is only connected at one end. Do not disconnect the mains earth from each piece of equipment. This is needed to provide both safety and screen returns to the system star point. -
Page 11: Inspection And Installation
2mm Allen key ENVIRONMENTAL CONSIDERATIONS The 1605/1603 Mixer will operate satisfactorily over a range of ambient temperatures from 0 C to +50C (+32F to +122F), and up to 80% non-condensing relative humidity. If the system is installed in an equipment rack, console or desk with high heat producing equipment (such as power amplifiers), adequate ventilation should be provided in order to assure longest component life. -
Page 12: Making Adjustments And Fitting Spares
Pull off all the pot knobs. Undo the 9 (for 1605) or 8 (for 1603) retaining Allen screws using a 2mm Allen key. The fascia can now be lifted clear of the subframe underneath. Take care not to bend the panel. -
Page 13: Replacing The Cross- Fader
Undo the 7 (1605) or 6 (1603) Allen screws using a 2mm Allen key. The fader panel can now be lifted clear of the subframe underneath. Take care not to bend the panel. Replacing The Channel Faders Using a 2mm Allen key undo and remove the 2 screws which secure the fader to the fader panel. Unplug the 8-pin connector, appying slight lateral force to the plug from side to side as you pull the plug from the socket. -
Page 14: Moving The Rear Connector Panel
MOVING THE REAR CONNECTOR PANEL It is possible to move the rear connector panel from its factory default position to its alternative location underneath the console. This alternative position can make it easier to rack or furniture-mount the console. To move the rear connector panel proceed as shown in the following diagram. -

This gives a cut or boost of +/-12dB to frequencies centred at 600Hz This gives a cut or boost of +/-12dB to frequencies below 60Hz When this switch is depressed its internal LED lights up. This indicates that the channel’s signal is being routed to the master section. -

Meters The L & R bargraph meters show, by default, the signal levels at the Master Left and Right outputs. If any Cue switch on the desk is pressed the meters display the level of the cued signal. Split Switch If the Split switch is depressed the meters will show a mono sum of the cued signal on the left meter, and a mono sum of the pre- fader master outputs on the right meter. - Page 24 Booth The booth eq has two bands. Both controls give a cut/boost of +/-6dB. Level The level of the booth outputs is controlled via this pot. Left/Stereo/Right This 3-position works as follows: left: mono signal is fed to booth left ouput only stereo: normal stereo right: mono signal is fed to booth right ouput only When depressed this switch causes the booth outputs to be cut by 12dB.

EXTERNAL MUTE OPERATION If the external mute mode is enabled the following happens when the n.c. link on the rear of the console goes open circuit: The pre-insert signal from the mic on channel 1 is routed directly to the master outputs, bypassing all level controls and eq controls. -

- Page 29 Earth Loop (Ground Loop): The result when the equipment sees more than one path to the system earth. Current flows because a resistive loop susceptible to radio and mains interference is formed. In severe cases this can result in audible hum or buzz in the system. Breaking the loop by removing all but one path to earth usually solves the problem.
- Page 30 Polarity: Sometimes erroneously referred to as ‘phase’ this is the + / - sense of a balanced signal or loudspeaker connection. Reversed polarity should be avoided and checked for as it can cause uncomfortable phasing effects as the listener moves between the speakers. Polarity Reverse is often used to correct for wrongly wired cables and connectors.
