1、 ALLEN do not rest the console on the meterbridge. 4. Remove the side trim and bracket from the side of the console that is to have the expander fitted. Similarly; remove the side trim and bracket from the side of the expander that is to be joined to the console. Figure shows console to be expanded

2、on right hand side Allen to prevent damage to the console chassis, the expanded console must be supported along its entire length. Should you experience any difficulties in fitting this module or have any queries regarding your GL4000 console please contact your ALLEN Groups 1 to 8, Left, Right and

3、Mono. The meterbridge is available in various sizes to fit each console size and runs full length. Connecting the meterbridge to a console is very easy and only requires plugging in the meterbridge harness and tightening the three grub screws in the lower lip of the meterbridge.

Origin of the change: In accordance with All

7、en & Heaths policy of continual product development, a new fader has been specified for GL4000 consoles. The fader offers a custom taper that has been designed to match the needs of engineers using the consoles in todays live environment. Details: GL4000s with serial numbers which precede the cut-of

8、f number stated above have been fitted with Jung Poon faders. The order codes for these are: AI2665 - Mono Fader AI2664 - Stereo Fader GL4000s from Serial No 401300 onwards will be fitted with the Alps K-fader which has a special taper. The numbers for these are as follows: AI8109 - Mono Fader AI811

9、0 - Stereo Fader Note that since the tapers of the two faders are different, it will be necessary to check that the correct fader is ordered whenever replacements are needed. Otherwise, the channel gain will not correspond to the fader panel silk-screen. Please note however that the audio performanc

10、e of the console will not be compromised by inadvertently fitting the wrong fader type. The channel will perform equally well with either fader type.

27、BY MISHANDLING AND/OR MISCONNECTION, ONLY TECHNICALLY COMPETENT PERSONNEL SHOULD ATTEMPT SERVICE WORK ON THIS UNIT. POWER SUPPLY SECTION D ALLEN & HEATHSection D - 2L4DSM2 TECHNICAL DESCRIPTION The ALLEN & HEATH RPS11 power supply is purpose designed for the GL4000 range of sound reinforcement conso

28、les. CONSTRUCTION All metal chassis for rack mounting in a 19 by 3U space. The unit comprises of a 16swg steel front panel with integral top cover and a separate 16swg steel chassis base on which all the main components are mounted. INSTALLATION The RPS11 is designed to occupy 3U (5.25 inches) of ra

29、ck space. An important consideration when rack mounting the unit is the need for natural convection of air flow over the whole unit. Good ventilation below the unit, in the floor or back of the rack, will ensure a path for continuous air flow. Other equipment in the rack which is known not to produc

30、e a significant amount of heat should be mounted below the unit. Equipment which also relies on good air flow within the rack (i.e. most power amplifiers and other power supplies) should be given due consideration and some space should be provided between such units and between the RPS11 unit. Force

31、d convection, by means of a fan-tray, may be desirable in this situation. The RPS11 can be operated as a free standing unit without requiring any special cooling arrangement, but should not be covered in any way. Always stand the unit on a firm flat surface well away from any soft furnishings. THE P

32、OWER SUPPLY AND CONSOLE EARTHING The RPS11 is a linear power supply which, like other linear supplies, produces DC voltages by rectifying, smoothing and regulating AC voltages from the secondary windings of a mains transformer. This unit connects to the local AC mains supply and provides the regulat

33、ed DC operating voltages required by the GL4000 console. The RPS11 DC output lead is terminated at both ends with an inline 10 pin round connector. A male connector at one end and a female connector which plugs into the console DC INPUT at the other. Near to the console DC INPUT connector is an eart

34、h terminal labelled CHASSIS GROUND. This terminal is connected to mains earth via the DC power cable of the RPS11. THE CHASSIS METALWORK IS ALWAYS CONNECTED TO MAINS EARTH VIA THE EARTH WIRE IN THE MAINS PLUG. DO NOT REMOVE THE EARTH WIRE CONNECTION IN THE MAINS PLUG ! SPECIFICATION AC MAINS INPUT V

37、 fuse is located on the rear of the RPS11 unit next to the AC mains connector. In the event of a mains surge or under-rated fuse value, the mains input fuse will rupture. Switch the unit mains “on/off ” switch to the off position and remove the mains lead plug from the “AC MAINS IN” socket on the re

38、ar of the unit. Lever out the fuseholder square top with a suitable tool and pull the fuse carrier assembly clear of the body. Replace the fuse and push the fuse carrier back into place.Check that the AC mains input voltage setting is correct for the mains supply in your area before switching the un

39、it on again. Check the correct fuse is fitted for the selected mains input voltage. Voltage Setting Fuse 220/230 VACT 3.15A / 250V20mm 100/120 VACT 5.0A / 250V20mm MAINS VOLTAGE SETTING The RPS11 is capable of operating over a wide range of AC mains input voltages by means of a comprehensive set of

40、selectable voltage settings. It is important to check that the RPS11 has the correct voltage setting as marked on the rear panel of the power supply. Confirm that the voltage setting matches the local AC mains supply in your area. Check the arrow indicates the correct AC mains voltage setting for yo

41、ur local AC mains supply To alter the AC mains input voltage setting, lever out the fuseholder square top with a suitable tool. Pull the fuse carrier assembly clear of the body, rotate the fuse carrier body until the required voltage aligns with the arrow and push the fuse carrier back into place. C
