Operating Instructions
The SH-GE 90 offers various controls for sound customization.
Equalizer Adjustment
- 24-Band Control: Use the individual sliders to adjust the gain (boost or cut) for each of the 24 frequency bands. This allows for precise shaping of the audio spectrum.
- Frequency Response Display: The unit features a spectrum analyzer display that visually represents the frequency response. Observe this display while making adjustments to understand the impact on the sound. There are typically three display types to choose from.
- Preset Modes: The SH-GE 90 may include several factory preset equalization curves (e.g., Rock, Pop, Jazz, Classical). Select these for quick sound adjustments.
- User Memory: You can typically store custom equalizer settings in user memory slots for recall. Refer to the on-screen menu or front panel controls for saving and loading presets.
DSP Sound Field Processing
Engage the DSP (Digital Sound Field Processor) function to simulate different acoustic environments, such as a concert hall, stadium, or club. Use the dedicated DSP controls to select and fine-tune these effects.
Microphone Input
The two microphone inputs feature level regulators. Adjust these controls to achieve the desired microphone volume without distortion.
Remote Control
The included remote control allows for convenient adjustment of most functions from a distance. Ensure the remote has fresh batteries and an unobstructed line of sight to the unit's IR receiver.
Maintenance
Proper care will ensure the longevity and optimal performance of your SH-GE 90.
- Cleaning: Gently wipe the exterior surfaces with a soft, dry cloth. For stubborn marks, slightly dampen the cloth with water. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the finish.
- Ventilation: Ensure that the ventilation openings on the unit are not blocked. Restricted airflow can lead to overheating and potential damage.
- Storage: If storing the unit for an extended period, disconnect it from power and store it in a cool, dry place, protected from dust.
