3. Setup and Installation
This fader is an internal component and requires professional installation within a compatible audio mixing console. Improper installation can lead to damage to the fader or the mixer.
3.1 Safety Precautions
- Ensure the mixer is powered off and disconnected from all power sources before beginning installation.
- Wear anti-static wrist straps to prevent electrostatic discharge (ESD) damage to sensitive electronic components.
- Use appropriate tools for disassembly and reassembly of the mixer.
- Refer to the specific service manual of your Alan Mixer GLD80 for detailed disassembly and reassembly procedures.
3.2 Installation Steps
- Carefully open the Alan Mixer GLD80 chassis according to its service manual.
- Locate the fader assembly that needs replacement or installation.
- Desolder the existing fader (if replacing) from the circuit board, noting the orientation of the pins.
- Align the new GLD80 170MM motor fader potentiometer with the corresponding holes on the circuit board. Ensure the motor and shaft orientation are correct.
- Solder the fader pins securely to the circuit board. Ensure all solder joints are clean and strong.
- Carefully reassemble the mixer chassis, ensuring all screws are tightened and connections are secure.
4. Operating Instructions
Once installed, the motor fader operates as an integral part of the Alan Mixer GLD80's control surface. Its primary function is to provide precise, motorized control over audio channel levels or other assigned parameters.
4.1 Manual Operation
The fader can be moved manually by hand to adjust the corresponding parameter. The B10K potentiometer provides a logarithmic resistance curve suitable for audio level control.
4.2 Motorized Operation
The integrated motor allows the fader to automatically move to a position commanded by the mixer's internal automation system or external control signals (e.g., MIDI, DAW automation). This feature is crucial for recalling scenes, automating mixes, and maintaining precise level synchronization.
- Ensure the mixer's automation features are enabled and configured correctly.
- Observe the fader's movement during automated playback to confirm proper function.
- Avoid forcing the fader manually against strong motor resistance, as this may damage the motor or gears.
5. Maintenance
Proper maintenance ensures the longevity and reliable performance of the motor fader.
5.1 Cleaning
- Keep the fader slot on the mixer clean and free of dust and debris.
- Use a soft, dry, lint-free cloth to wipe the fader knob and surrounding area.
- For internal cleaning (only if necessary and by qualified personnel), use compressed air to gently remove dust from the fader track and motor assembly. Avoid using liquid cleaners directly on the fader mechanism.
5.2 Lubrication
The fader mechanism is typically pre-lubricated. Avoid applying additional lubricants unless specifically recommended by the mixer manufacturer's service manual. Improper lubricants can attract dust and degrade performance.
5.3 Inspection
Periodically inspect the fader for smooth operation. If you notice any grinding, sticking, or inconsistent movement, consult a qualified service technician.
