4. Instruções de operação
4.1 Operação básica
The TT 25-CXA is an active monitor, meaning it has a built-in amplifier. Once powered on and connected to an audio source, it will reproduce the incoming audio signal. Adjust the input sensitivity as needed, typically -2 dBu for consumer-level equipment or +4 dBu for professional line-level signals.
4.2 DSP Processing and Presets
The monitor features integrated DSP processing. This allows for precise control over various audio parameters, including crossover frequencies (900 Hz), protections (Thermal, HF), and limiting (soft limiter, dynamic). The unit includes 8 selectable presets to optimize performance for different applications or environments. Consult the rear panel controls or the RDNet software for preset selection and advanced DSP adjustments.
4.3 Monitoring Applications
The TT 25-CXA is versatile and suitable for various monitoring roles:
- Vocal Stage Monitorar: Its accurate and deep voicing, with transparent mids and accurate high frequencies, makes it ideal for main vocal monitoring.
- High-Output Drum or Keyboard Monitor: Capable of delivering high SPL, it can effectively monitor drums or keyboards.
- Sidefill Monitor: For small to medium-scale applications, it can serve as a sidefill monitor.
5. Manutenção
5.1 Limpeza
To clean the exterior of the monitor, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by a dry cloth. Do not use abrasive cleaners, solvents, or waxes. Ensure no liquid enters the speaker grille or control panel.
