4.2 Subgroup Operation
The SX2442FX features four subgroups (SUB 1-4) which allow you to group multiple channels and control their overall level with a single fader. This is useful for managing drums, vocals, or other instrument sections.
- Assign desired channels to a subgroup using the SUB 1-4 buttons on each channel strip.
- Adjust the overall level of the subgroup using its dedicated fader.
- Subgroups can be routed to the main mix using their respective MAIN buttons.
4.3 Main Mix Operation
The main stereo mix is controlled by the MAIN MIX faders. All channels and subgroups routed to the main mix will be combined here. The main mix also features a 9-band stereo graphic equalizer for overall frequency adjustment and a feedback detection system.
4.4 Dual Multi-FX Processor Usage
The mixer includes two independent 24-bit stereo FX processors with 99 presets. These can be assigned to channels via the FX send controls on each channel strip.
- Select a desired effect preset using the program selector on the FX section.
- Use the FX SEND controls on individual channels to send signal to the internal effects processor.
- Adjust the FX RETURN faders to control the overall level of the processed signal in the main mix or monitor sends.
4.5 Monitoring and Talkback
The mixer provides various monitoring options, including headphone output and control room outputs. A dedicated TALKBACK microphone input and control allow for communication with musicians on stage or in a separate room.
5. Maintenance
5.1 Cleaning
Regularly clean the mixer's surface with a soft, dry, lint-free cloth. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish and controls. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth.
