Page 13: Installation
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 14: 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 15: Points To Remember
POINTS TO REMEMBER In all cases, 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 16: Inspection And Installation
INSPECTION AND INSTALLATION UNPACKING AND INSPECTION Your Model 1620LE was carefully packed at the factory, and the container was designed to protect the unit from rough handling. Nevertheless, we recommend careful examination of the shipping carton and its contents for any sign of physical damage which could have occurred in transit. - Page 17 LINE VOLTAGE SWITCH Unless a tag on the line cord specifies otherwise, the Model 1620LE was shipped ready for operation with nominal 240 V AC power mains. To change this for nominal 115 V AC operation, slide the VOLTAGE SELECTOR switch on the rear panel to the 120 position. The voltage is visible in a window next to the switch slot.

Microphone Input: The AUX 4 preamplifier position is supplied from the factory with a microphone preamplifier, Part No. 1620-PC, installed. Connection is made via a standard XLR-type socket. The wiring convention is: Pin 1 – Screen Pin 2 – Hot +ve Pin 3 –... -
Page 19: Output Connections
OUTPUT CONNECTIONS House Output: The main or house output of the Model 1620LE is available on the Rear panel in Balanced and Unbalanced form. Balanced Output, via XLRs, is transformer isolated and floating. Balanced or symmetrical lines should be connected as follows: Screen Hot +ve Cold -ve... -
Page 20: Mono Output
If the installation is to include booth monitor speakers and a booth microphone, care should be taken to turn down the booth output before turning up the microphone input to prevent acoustic feedback. Similarly, do not turn up the booth output until the booth microphone has been turned down. - Page 21 Headphone Monitor The headphone monitor output appears on a 6.3 mm (1/4 in.) three-conductor stereo phone jack on the front panel. The minimum recommended impedance of the headphones is 200 Ohms per side. IMPEDANCE AND TERMINATION Modern audio systems utilise amplifiers and other active devices which have very low output impedances and high (10k to 50k) input impedances.

Page 24: Headphone
HEADPHONE The headphone circuit is designed as a cue and monitoring circuit. With the CUE/PGM switch in the PGM position, the program signal is fed to the headphones. With the switch in the CUE position, the signal feed is taken from before the individual input level controls. A six position selector switch determines which input will be heard. -

To install a connector and preamplifier card: Remove the three screws fastening the top cover of the 1620LE to the chassis, and remove the cover. -
Page 28: Aux 4 Input : Bypassing Master Gain Controls
AUX 4 INPUT : BYPASSING MASTER GAIN CONTROLS The Model 1620’s microphone signals will appear at the tape outputs and effects loop, and will be affected by the house master and tone controls. In some circumstances, it may be desirable to keep the mic signal from appearing at these points so that it does not get processed along with the music and is not recorded on tape. -
Page 29: Tone Control Bypass
TONE CONTROL BYPASS In some circumstances, it may be desirable to defeat the tone controls. To disable these controls: Remove the three screws fastening the top cover of the 1620LE to the chassis, and remove the cover. Locate the Tone Control circuit board on the right side of the front panel. Press and release the EQ IN/EQ OUT switch until it is in the EQ OUT position.
