GL2200 MIXING CONSOLE

Transcription

1 GL2200 MIXING CONSOLE SYS-LINK EXPANDER OPTION This option connects a GL2200 console as a channel expander to a second console with just one or two interconnecting cables. Kit GL2200-SL1 = SINGLE Single option to install SYS-LINK to one GL2200 console to allow interconnection to a second console already fitted with SYS-LINK. Interconnecting cables not supplied. For information on using SYS-LINK please refer to APPLICATIONS NOTE AP3623 FITTING INSTRUCTIONS Publication AP3622 ISSUE 1 JAN 99

2 FITTING THE GL2200 SYS-LINK EXPANDER OPTION 1) CHECK THE CONTENTS: GL2200-SL1 KIT RED, VIOLET, YELLOW, BLUE (ALL) BLUE GREEN ORANGE RED SYS-LINK IDC HARNESS SNAP-IN PILLARS fig. 1 Contents: 1x SYS-LINK circuit board assembly with interconnecting harness and mountings already fitted. 1x SYS-LINK Fitting Instructions (AP3622) 1x SYS-LINK Application notes (AP3623) 1x IDC Harness (AL3616) 2x Snap-In Pillar (AB2233) 1x 8K2 Resistor (AC0045) 2) TOOLS REQUIRED: SLIM BODIED SOLDERING IRON WITH SMALL TIP SOLDER 1pt CROSS POINT LONG NOSE PLIERS 5mm NUT DRIVER 2 GL2200 SYS-LINK OPTION ALLEN & HEATH

3 3) PRELIMINARY: To fit the SYS-LINK option it is not necessary to remove any of the circuit board assemblies as access to the SYS-LINK solder pads can be made with the circuit boards in place. 4) REMOVE THE CONSOLE BASE: Before inverting the console to remove the base, remove the two screws next to the end stereo input channel on the console front panel. Then invert the console and remove the base as shown in fig. 9. 5) REPLACE R45 RESISTOR: Referring to fig. 2 and fig. 3; if R45 is a 22K resistor (bands: red, red, orange) then this needs to be replaced by the supplied 8K2 resistor (bands: grey, red, red). However, if R45 is already a 8K2 resistor (bands: grey, red, red) then do not replace. R45 OSC/Noise fig. 2 6) REMOVE THE BLANKING PLATE & POWER SUPPLY BRACKET The SYS-LINK blanking plate is located on the rear panel. Unscrew the retaining screws and remove the blanking plate. The power supply bracket is located under the PSU. Unscrew the two screws (A) and remove the bracket as shown in fig. 3. ALLEN & HEATH GL2200 SYS-LINK OPTION 3

4 7) DISCONNECTING THE HARNESS ASSEMBLIES: Disconnect the MAIN HARNESS (B) plugged into the connectors mounted along the edge of the circuit boards. Disconnect the flexible flat cables (C) plugged into the GROUP circuit boards. A OSC/Noise C B CONSOLE FRONT GL2200 inverted with the base cover removed. fig. 3 8) FITTING THE SYS-LINK IN HARNESS: Remove the two screw fixings from the harness D Type connector. Mount the D Type connector onto the rear panel with the fixings. Mount the other connector onto the straight molex connector on the Osc/Noise as shown in fig. 4.

5 9) POSITIONING THE SYS-LINK ASSEMBLY: Fit the bracket to the SYS-LINK circuit board assembly with the 2 nylon snap-in pillars (D) as shown in fig. 5. Place the SYS-LINK and bracket assembly on the console as shown ready for soldering the wires.

Note, the wires for the Group, Left & Right s are soldered to the trackside of the circuit boards and not the component side. The wires to the OSC/Noise go through the. It is recommended that the wires in the SYS-LINK harness are soldered to each circuit board in the following order: OSC/Noise, GROUP 3, GROUP 1, LEFT and then finally the RIGHT circuit board assembly.

7 11) FITTING THE SYS-LINK OUT ASSEMBLY: When all the SYS-LINK wires have been soldered, remove the 2 screw fixings from the D Type Connector and manoeuvre the SYS-LINK circuit board and power supply bracket assembly into the console chassis as shown in fig. 7. Mount the D Type Connector onto the rear panel with the 2 fixings.

8 12) REFIT THE POWER SUPPLY BRACKET: Carefully stand the console on its rear panel and re-fit the two front panel power supply bracket screws next to the end stereo input channel. Support the console during this process. Place the console on its control surface and fit the two power supply sub chassis screws. 13) REFIT THE HARNESSES: Referring to fig. 8, re-fit the MAIN HARNESS (B) onto the circuit boards. Check the harness is correctly aligned onto the circuit board connectors with pin 1 aligned with the red stripe of the ribbon harness. Reconnect the two flexible flat cables (C) to the GROUP circuit board assembly. Ensure that all harnessing is tidy. 14) REFIT THE BASE: fig. 9 Refit the base. Locate the two screws for the power supply bracket before fitting the other screws. 15) PLUG ON THE INTERCONNECTING CABLES: SYS-LINK connectors are 25way D Type female. Use 25way D Type male to male connector cables. Connect pin one to pin one on all connectors. Connect shield (screen) to 0V. Standard cables are available from electronic suppliers or computer shops. It is advised that the cable is a screened type less than 10 metres. Use professional quality locking connectors. When connecting to equipment other than the GL Series link all unused audio inputs to 0V earth at the SYS-LINK input. 16) TEST THE SYSTEM: Test all SYS-LINK inputs and outputs for correct signal level and quality by probing the D Connector pins or by interconnecting two consoles with SYS-LINK fitted. Test the PFL/AFL system for correct DC buss switching. The SYS-LINK circuit diagram and technical details are included for reference.
